2.5 Specifications

Installation Instructions

3.1 Location & Mounting
The DVP-1200 should be installed in a centralized location, easy to access and protected from environmental elements. A Mechanical room, Alarm Control Room, or other similar areas are recommended.
Mounting holes are provided in the DVP-1200 case at the four corners. See Figure 3-1. The panel should be mounted with space around the panel for access to conduit entry holes provided on the top, bottom, and right side of the panel.

3.2 Installation
3.2.1 General Wiring Information
WARNING
This equipment helps monitor for the presence and concentration level of certain specified airborne gases. Misuse may produce an inaccurate reading, which means that higher levels of the gas being monitored may be present and could result in overexposure. For proper use, see supervisor or User manual, or call Macurco Technical Service at 1-844-325-3050.
Field wiring is completed via modular connectors (provided), except for the safety ground, AC power, and relays. After wiring, simply plug the modular connectors into the matching connectors on the printed circuit board (PCB).

Note: It is recommended to always install with wires enclosed within the rigid metallic conduit.
The power to the remotely mounted sensors should be size AWG18 (minimum) for short runs. Refer to Table 3-1 for recommended wire gauges.

Table 3-1 – Wire Gauge for run Length
Do not bundle sensor power or sensor signal connections with other AC power cables to prevent electrical interference. If other AC power connections must be bundled with the DVP-1200 sensor cables, the sensor connections should be made with two twisted pairs of the appropriate gauge, with an overall foil and braid shield. All shields should  be terminated at the DVP-1200 end of the cable only.
The power connections to the MRS-485 and remote mounted sensors should be size 18 AWG (minimum) for short runs. Refer to Table 3 1 for recommended wire gauges. The power for the MRS-485 adapter is connected via a two-terminal screw type connector, 12 to 24 VAC or 12 to 24 VDC and no polarity.
The MRS-485 adapter output is wired in the standard 2W-Modbus circuit definition with selectable built-in terminating resistors at the ends of the RS-485 bus. It is recommended to always use twisted wires to reduce noise and allow for reliable data communication over greater distances. For best performance use shielded 3-conductor wire with one twisted pair providing a pair for signal (A & B), common (COM) and shield ground (SHD) connections. Use at least 3-conductor wire with one twisted pair providing a pair for signal (A & B) and common (COM) connections. The Macurco MRS-485 Modbus output is connected via a four-terminal screw type connector.
Running the Modbus cable adjacent to or in the same conduit with high voltage wires is not recommended as there may be interference from the high voltages near the bottom left corner of the panel.
3.2.2 Installation Diagram

3.2.3 Power Connection
The main power cable should be routed into the bottom left conduit entry.
Macurco recommends a minimum wire size of 18 AWG and the wire insulator must be rated for at least 140°F (60°C) service.
The power connector will accept wire from 12-24 AWG.
The safety ground wire should be connected to terminal labeled as GND. Connect the wires to the following terminals:

Table 3-2 – Input Power Connection

1. The line, neutral and ground wires should be stripped 1/4 in. (6.5 mm).
2. Press down the white button of the connector. You can use flat-headed screwdriver for this.
3. Insert the bare wire into the respective wire cavity of the connector. Refer Table 3-2.
4. Release the white button.
5. Ensure that the wire cannot be easily pulled from the connector.

Note: For ethernet connection, use surge protector (Model: DTK-MRJPOE manufactured by DITEK) and connect one end of the surge protector to DVP-1200 ethernet connection.
3.2.4 Remote Sensor Connection
Remote sensors must be connected to the DVP-1200 at one of the three RS-485 connectors labeled “MRS-485 DETECTOR CONNECTION”.
3.2.4.1 MRS-485 Connection and Operation
The Macurco MRS-485 Adapter converts the Macurco 6-Series 4-20mA analog output to a digital output for use with the DVP1200 and other addressable network systems.
To install the MRS-485 on a Macurco 6-Series detector,

1. Remove the 4-20mA/Power plug from the Macurco 6-Series gas detector
2. Plug the MRS-485 adapter into the empty socket.
3. Install the provided MRS-485 screw.
   

Power connections to Macurco sensors used with the DVP-1200 are polarity- insensitive (no polarity) since a bridge rectifier is connected to the power input terminals. All sensors used with the DVP-1200 panel employ screw clamp terminal blocks for power and signal connections. The polarity of the current loop connections is marked on the printed circuit board of the sensor.
The MRS-485 will monitor the 4-20 mA current output of the detector. At power up and during its warm-up period, the 6-Series detector will communicate its sensor type over the 4-20 current output using a custom protocol. The MRS-485 will automatically register each 6-Series detector as it is programmed with information about all the detectors to which it can be connected. The
MRS-485 will use this information to determine the gas level sensed by the 6-Series detector by measuring the 4-20 mA currentloop output during normal operation of the
detector.
When the LED is solid GREEN, the operation is normal, the MRS-485 knows the detector type, no errors are detected, and no MODBUS data are being received or transmitted over the RS-485 line.
When the LED is GREEN with random bursts of AMBER, the operation is normal, and data are being received or transmitted over the RS-485 line. The AMBER LED will come on anytime that there is data traffic.
NOTE: After complete system installation, verify all sensors (verify sensor address and sensor type) connected to the panel are detected by the panel and there is not any trouble indication for any of the connected detector.
3.2.4.2 Connection
The Macurco MRS-485 output is connected via a four-terminal screw type connector. The MRS-485 adapter is wired in the standard 2W-Modbus circuit definition with selectable built-in terminating resistors at the ends of the RS-485 bus. The power for the MRS-485 adapter is connected via a two-terminal screw type connector, 12 to 24 VAC or 12 to 24 VDC and no polarity.
NOTE: Running the Modbus cable adjacent to or in the same conduit with high voltage wires is not recommended as there may be interference from the high voltages.

3.2.4.3 Dip Switches and Addressing
Each MRS-485 (and the detector it’s connected to) must be configured to a unique address. If there are 10 detectors on the serial line, then 10 unique addresses must be used, one for each detector. To set the address, use the eight DIP switch positions.
For each unit choose the value from 1 to 192 (see chart) and set the eight switches to match the address. UP means ON or 1 and DOWN means OFF or 0. For example, to configure a unit as address “50”, set switches “2, 5, 6” (see Table 3-3) to ON or in the up position (01001100).
NOTE: If CX-6 is assigned address X and connected to DVP-1200, then address X is assigned to NO2 Sensor (Type: 2) and address X+1 is assigned to CO Sensor (Type: 1) by the panel.

3.2.4.4 Topology
An RS485-MODBUS configuration without repeater has one trunk cable, along which devices are connected, directly (daisy chaining) or by short derivation cables. The trunk cable, also named “Bus”, can be long. Its two ends must be connected on “Line” Terminations. (see Section 3.2.4.5 Line Termination – End of Line Resistor). The use of repeaters between several RS485MODBUS is also possible.
The DVP-1200 has three Modbus termination blocks that will accept two trunk cable connections allowing for two MODBUS communication lines. The Trunk cable must be wired in parallel from the panel to the end of line with no off shoots “T-tapping”.
3.2.4.5 Line Termination – End of Line Resistor
The MRS-485 and DVP-1200 are wired in the standard 2W-Modbus circuit definition with selectable built-in terminating resistors at the ends of the RS-485 bus. The MRS-485 and DVP-1200 provide integral termination for the end of line resistors (EOL). The terminations use 4-pin connector with a jumper to select termination: The user  selects no termination or one of the two Modbus line termination options. The MRS-485 and DVP-1200 have two-line termination options (100 Ohm and 120 Ohm)
available.
Place the EOL jumper on one of the following positions:
N = No termination (default)
2 = 120 ohm
1 = 100 ohm

3.2.4.6 Baud Rate
At the baud rate of 19200 (default baud rate for Macurco MRS-485 and DVP-485) and with cables less than 1,000 ft. in length, termination resistors are not recommended.
At the baud rate of 19200 and with cables longer than 1,000 ft., termination resistors are recommended.
It is recommended to use an RS-485 type of cable and 120 ohms for termination resistor.
An RS-485 network requires a 3-wire cable: a twisted pair and a third wire. It is difficult to tell whether shielding is required or not in a particular system until problems arise, so it is recommended to always use shielded cable.
When using termination resistors use only 2 resistors, one at each end of the RS-485 transmission line (i.e. 1 at the DVP-485B and 1 at the last/farthest MRS-485).
For any other baud rates calculate when (at what length) termination resistors are required. This is calculated by dividing the length L by the ratio between the new baud rate and 19200 or (x/19200) where x is the new baud rate.

For example, if new baud rate is 9600

Use termination resistors when cables are longer than 2000 ft.
For example, if new baud rate is 38400

Use termination resistors when cables are longer than 500 ft.
NOTE: Other manufacturers may have different recommendations on wire length and EOL resistor usage.

At 19200 baud rate (default), 1000 ft or less, and using RS-485 or Cat-5 type cable

At 19200 baud rate (default), more than 1000 ft, and using RS-485 type cable
3.2.4.7 Wire Selection
For best performance, use shielded 3-conductor wire with one twisted pair providing a pair for signal (A & B), common (COM) and shield ground (SHD) connections.
For the balanced pairs used in an RS485 system, wire with a characteristic impedance of higher than 100 Ohms may be preferred, especially for 19200 and higher baud rates.
3.2.4.8 Wire Length
For the RS485-MODBUS, the wire gauge must be chosen sufficiently wide to permit the maximum length (1000 m or 3281ft). 24 AWG is always enough for the MODBUS Data. The modular RS-485 connector will accept wire from 16 to 28 AWG. The wire insulator must be rated for at least 140°F (60°C). Category 5 cables may operate for RS485-MODBUS, to a maximum length of 600 m 1968.5 ft.
The maximum length of the trunk cable depends on the

• baud rate
• cable (gauge, capacitance or characteristic impedance)
• number of loads on the daisy chain
• network configuration (2-wire)

For a maximum 9600 Baud Rate and 26 AWG (or wider) gauge, the maximum length is 1000m (3281ft). The derivations must be short, never more than 20m (65.5ft). If a multi-port tap is used with n derivations, each one must respect a maximum length of 40m (131ft) divided by n.
3.2.4.9 Grounding
The Common Circuit (COM) must be connected directly to protective ground, preferably at one point only for the entire bus.
The shield should be connected to each detector at the SHD terminal and connected to a ground terminal or chassis only at one end of the bus.
3.2.4.10 External Power Supply
Select a UL Listed NEC Class 2 power supply which can power the MRS-485 units connected to 6-Series detectors.
To determine the required minimum power supply,

• Each MRS-485 connected with a detector is rated at 3.25W.
• The minimum power which the power supply needs to deliver for 12 detectors is figured as: 12 detectors x 3.25 W pedetector = 39W
• Therefore, a 24VDC, 60W power supply will work.

3.2.4.11 Power Wire
All field wiring is completed via modular connectors (provided). After wiring, simply plug the modular connectors into the matching connectors on the MRS-485. The power connections to the remotely mounted detectors should be size 18 AWG (minimum) for short runs. Since Macurco detectors are rated for operation between 12 and 24 VDC  or VAC, the voltage drop between the power supply and the MRS-485 should not be an issue if the recommended power wire gauge guidelines are followed.
The terminals will accept wire from 16 to 28 AWG. To install a wire, strip back approximately 0.25 in. (6 mm) of insulation and insert the bare wire into the terminal. Tighten the screw clamp and ensure that the wire cannot be easily pulled from the connector.
3.2.4.12 4-20mA Connection
There are three 4-20mA output modular connectors. The wire terminals for the three 4-20 mA connectors are available at the connector labeled “4-20mA O/P”. The connector accepts wires from 16 to 28 AWG. Refer to Figure 3-4 for details.
3.2.4.13 Relay Connection
The wire terminals for the four onboard relays are available at the connectors labeled “R1”, “R2”, “R3”, and “R4”. The wire terminals for the optional expansion relays are available at the connectors labeled “R5”, “R6”, “R7”, and “R8”.
Each relay will be wired to be either normally open (NO) or normally closed (NC). There is no polarity for these connections.
Each terminal can accommodate a wire size from 12 to 24 AWG.
Connect one wire to the COM terminal. For normally open (NO) configuration, connect the other wire to the NO terminal. For normally closed (NC) configuration, connect the other wire to the NC terminal.
To connect wires to the relay terminals,

1. Strip each wire back 1/4 in. (6.5 mm).
2. Press down the white button of the connector.
3. Insert the bare wire into the wire cavity of the connector.
4. Release the white button.
5. Ensure that the wire cannot be easily pulled from the connector.

3.2.5 Remote Relay Connection
In addition to the onboard relays (four standard and four optional), the DVP-1200 can be connected to two additional remote relays. Each remote relay box includes two relays.
The wire terminals for the Remote Relay are available at the connector labeled “REMOTE RELAY CONNECTION”.
3.2.5.1 Remote Relay (RR-24) Mounting
Macurco RR-24 is shipped with mounting brackets and screws. Install mounting brackets on the back four corner of the enclosure. RR-24 should be mounted with sufficient space all round for access to conduit entry holes provide on the top and bottom side of the unit.
3.2.5.2 Remote Relay (RR-24) Wiring
All the connectors in RR-24 are spring tightening and will accept wire from 14 to 24 AWG. To connect the wires to terminals, press down the white button of the connector (use flat-headed screwdriver), insert bare wire into respective wire cavity of the connector and release the white button. Ensure that the wire cannot be easily pulled from the connector. Refer to figure below for location of different connectors in RR-24.
The power connections to the RR-24 should be size AWG18 (minimum) for short runs. For longer run follow recommended power wire gauge guidelines. Match the polarity for power connection.
For RS-485 or communication connection it is recommended to always use a twisted wire to reduce noise and allow for reliable data communication over greater distances. For best performance use shielded 3-conductor wire with one twisted pair providing a pair for signal (A & B), common (COM) and shield ground (SHD) connection.
NOTE: Running the RS-485 cable adjacent to or in the same conduit with high voltage wires is not recommended as there may be interference from the high voltages.
RR-24 provide integral termination for end of line resistors (EOL). The termination uses 4-pin connector (labeled J8) to select termination. Place the EOL jumper on one of the following positions:

• NU = No termination (default)
• 120 = 120 Ohm
• 100 = 100 Ohm

3.2.6 Remote Relay Operation
Power LED will light up green to indicate the unit is operational. TX LED will flash blue to indicate the unit is communicating with DVP-1200. RELAY 1 and RELAY 2 LED will light up red when corresponding relay is activated. Refer to Figure above for location of Relay 1 and Relay 2.
3.2.6.1 Changing RR-24 Settings
The DIP switches are used to set the Modbus address and are also used to change the communication settings. Valid Modbus addresses for RR-24 are from 1 to 192 where switch 1 is the least significant bit (LSB) and switch 8 is the most significant bit (MSB). Address 254 is used to place the RR-24 in programming mode.
3.2.6.2 Programming Mode
When the RR-24 is powered with address set to 254, it enters programming mode. The STATUS LED will be flashing RED and GREEN alternatively every 200 milliseconds to indicate that RR-24 is ready and waiting for the user to enter new communication settings using 8 dip switches. Using the 8 dip switches, use can change the communication settings like baud rate and parity.
When looking at the switches with “Address” marking on top, the switches are defined from left to right.

• Switch 8, switch 7 and switch 6 are used to modify baud rate
• Switch 5 and switch 4 are used to modify parity
• Switch 1 is used to request to save the new settings
• Switch 3 and 2 are unused and should be left in ON position.

Table 3-1 – Baud Rate configuration

Table 3-2 – Parity Configuration

Set the switches to the desired value and then set switch 1 to ON and then OFF, and the new settings will be saved in EEPROM.
The result of saving operation is displayed on STATUS LED. Alternating GREEN/OFF every 200 milliseconds indicates saving new settings passed and alternating RED/OFF every 200 milliseconds indicates that saving new settings failed. Once the new settings have passed, disconnect power from the unit, set the address for the device using the address switches and apply power back tounit.
3.2.7 Horn & Strobe Connection
There are four connection terminals for horns and strobes. The modular connectors are located at the top left of the board and are labeled “Horn/Strobe”.
Refer to Table 3 4 for recommended wire gauge vs. run length for the horn & strobe functions (maximum 2.5-volt drop in the wire). The horn & strobe circuits are Class 2 control circuits, so Class 2 conductors should be used

Table 3-4 – Wire Gauge vs. Run Length

4.4.4 Unoccupied Failure Display
When Title 24 is enabled, during unoccupied time, DVP-1200 compares the readings of all CO detectors connected (irrespective of assigned zones), and if any CO detector is more than 15 ppm above or below the average of all CO detectors for longer than 4 hours, the detector has failed. This failure is referred to as unoccupied failure in rest of the manual. Refer to “Section 4.6.3.5 for process to define occupied time. Time outside the defined occupied time is unoccupied time.
If there is unoccupied sensor failure, the panel will enter ALARM mode during which the internal buzzer will sound, the ALARM/WARNING LED will be red, and the display will switch to the ALARM status display. Any outputs assigned to alarm condition will be triggered. Figure 4-6 shows an example of DVP-1200 display during unoccupied failure. “FAIL – UNOCC.” on the screen indicates unoccupied failure.

DVP-1200 displays the address of the unoccupied failure detector. If there are more than one unoccupied failure detector, then display scrolls every 5 seconds to display all unoccupied failure detector.
If unoccupied failure sensor is part of a zone (Zone 2 in above figure), then the status of the zone will be updated to ALARM and all outputs assigned to that zone will get activate. If 4-20mA output is assigned to the zone with unoccupied failure sensor, then its output will be 20mA.
When the HUSH key is pressed and held for 5 seconds, the internal buzzer will be silenced for 4 hours. If the h orn or strobe turn on delays have not finished, then they will also be silenced.
When all indicators have been silenced, the display will show that unoccupied failure indications have been silenced for four hours and the display will return to normal mode. In VIEW SENSOR screen, sensors with unoccupied failure silenced will display “FAILED UNOCCUPIED” alternating with current gas reading.
4.4.5 Occupied Failure Display
When Title 24 is enabled, during occupied time, DVP-1200 compares the readings of all CO detectors assigned to a zone, and if any CO detector is more than 15ppm above or below the 30-minute rolling average of all CO detectors assigned to the corresponding zone, then the detector has failed. This failure is referred to as occupied failure in rest of the manual. Refer to “Section 4.6.3.5 for process to define occupied time.
If there is occupied sensor failure, the panel will enter ALARM mode during which the internal buzzer will sound, the ALARM/WARNING LED will be red, and the display will switch to the ALARM status display. Any outputs assigned to alarm condition will be triggered. Figure 4-7 shows an example of DVP-1200 display during unoccupied failure. “FAIL – OCC.” on the screen indicates occupied failure.

DVP-1200 displays the address of the occupied failure detector. If there are more than one occupied failure detector, then display scrolls every 5 seconds to display all occupied failure detector.
The status of the zone with occupied failure sensor will be updated to ALARM and all outputs assigned to that zone will get activate. If 4-20mA output is assigned to the zone with occupied failure sensor, then its output will be 20mA.
When the HUSH key is pressed and held for 5 seconds, the internal buzzer will be silenced for 5 minutes. If the horn or strobeturn on delays have not finished, then they will also be silenced.
When all indicators have been silenced, the display will show that occupied failure indications have been silenced for 5 minutesand the display will return to normal mode. In VIEW SENSOR screen, sensors with occupied failure silenced will display “FAILEOCCUPIED” alternating with current gas reading.
4.4.6 Calibration Due Warning Display
When there are up to 30 days until calibration for any carbon monoxide sensors connected, panel will trigger Calibration Due Warning. Calibration Due Warning has lower priority than gas warning. This feature is applicable only for carbon monoxide detector with calibration period feature with Title 24 feature enabled in DVP-1200.
DVP-1200 displays the address of the detector with calibration due warning. If there are more than one detector with calibration due warning, then display scrolls every 5 seconds to display all detectors with calibration due warning.
If there is a carbon monoxide sensor with calibration due warning, the panel will enter WARNING mode during which the internal buzzer will sound, the ALARM/WARNING LED will be amber, and the display will switch to the WARNING status display.
Any outputs assigned to warning condition will be triggered.

When the HUSH key is pressed and held for 5 seconds, the internal buzzer and horn/strobe will be silenced. Silence period is dependent on time left to calibration. Following table shows silence period for different time to calibration.

Table 4-2 – Calibration Due Silence Period

When all indicators have been silenced, the display will show that calibration due warning indication have been silenced for corresponding silence period. After approximately 5 seconds the display will return to normal mode. Only a calibration due warning with lower silence interval (refer Table 4-2) or calibration due warning from new sensor will reset the HUSH and panel will go back to state indicating Calibration Due Warning.
When in normal display mode, for detectors with Calibration Due Warning silenced, panel will display current gas reading alternating with “CALIBRATION DUE” in VIEW SENSOR screen for the corresponding sensor.
4.4.7 Calibration Overdue Trouble Display
When the panel detects a carbon monoxide sensor with Calibration Overdue condition it will go into trouble state. This trouble has higher priority than a regular trouble condition. This feature is applicable only for carbon monoxide detector with calibration period feature with Title 24 featured enabled in DVP-1200.DVP-1200 displays the address of the detector with calibration overdue trouble. If there are more than one carbon monoxide sensor with calibration overdue condition or are sensors in trouble due to other conditions, then display scrolls every 5 seconds to display all detectors with the trouble condition.
During Calibration Overdue trouble, the trouble LED will be ON (the POWER/TROUBLE LED will be red), and the display will switch to the TROUBLE status display. Any outputs assigned to trouble condition will be triggered. The status of the zone with calibration overdue carbon monoxide sensor will be updated to TROUBLE and all outputs assigned to that zone will get activated. If 4-20mA output is assigned to the zone with calibration overdue sensor, then its output will be 20mA.
When the HUSH key is pressed and held for 5 seconds, the internal buzzer will be silenced for 15 minutes. If the horn or strobe turn on delays have not finished, then they will also be silenced for 15 minutes.
When all indicators have been silenced, the display will show that calibration overdue trouble indication have been silenced for 15 minutes. After approximately 5 seconds the display will return to normal mode.
When in normal display mode, for detectors with calibration overdue trouble silenced panel will display “CALIBRATION REQUIRED” in VIEW SENSOR screen for the corresponding sensor.
4.5 Ventilation Control
The ventilation control function operates independently from the alarm function. It provides the ability to configure the DVP1200 for control of up to 8 zones. Each zone
can be configured to control relays and an external horn and strobe if desired.
When more than one zone is controlling a relay it only takes one zone to activate the relay, but all controlling zones must release the relay before it will turn off. Each of the relays, horn, and strobe has independent turn-on delays (to ignore short duration, transient gas signals) and turn off delays (to ensure minimum run times for fans that must run for internal cooling).
A VFD may be enabled and controlled by the DVP-1200 output relays or the DVP-1200 4-20mA output. This allows an operator to change fixed speeds for a VFD if it’s used as a stand-alone control.
Here is an example of an application where VFD is controlling the speed of a fan: An operator can close relay 1, 2, or 3 to set the fan speed. If relay 1 is closed, the VFD will operate at 50%, If relay 2 is closed, the VFD will operate 75%, If relay 3 is closed, the VFD will operate at 100%.
Each zone can respond to gas levels indicated by one or more of the sensors, with configurable turn on and turn off concentrations (rising and falling) for each gas type.
For example, each zone can be configured to monitor a separate set of four sensors and control a single relay.
A single sensor may be assigned to multiple zones if desired. Here is an example of a control scheme which has single sensors assigned to multiple zones:

1. One zone monitors all sensors and turns one relay on at a relatively low gas concentration.
2. A second zone monitors the same sensors and turns on a second relay if the gas concentration reaches a higher level.
3. A third zone also monitors the same sensors and turns on the last relay as a signaling device to a live monitor station, as well as turning on an external horn and strobe.

In addition to controlling the relays based on the gas concentration, each zone can have a timed function, e.g. turn on low volume ventilation fans at 7:00 AM and turn them off at 8:00 PM.

display a message if an invalid value is entered. Values entered cannot be larger than range of the detector, rising value must be equal or greater than Falling value, and Alarm value must be equal or greater than Warning. Refer to Table 4-2 for default values for each field or menu item.

The following options are available for GROUP CONFIGURATION:

• RISING – If the gas concentration is greater than or equal to this level, the zone output(s) will be turned on.

• FALLING – If the gas concentration is less than or equal to this level, the zone output(s) will be turned off.

• WARNING – The gas concentration used to trigger a warning status for the group of sensors within the zone. Setting a warning level of 0 (zero) will disable warning detection for this sensor.

• ALARM – The gas concentration used to trigger an alarm status for the group of sensors within the zone. Setting an alarm level of 0 (zero) will disable alarm detection for this sensor.

• MODE – When multiple sensors are being monitored by a group, the output decision can be based on either voting, or the average of all sensors in the group. Valid modes are AVERAGE or VOTING (default). The bottom box in the LCD displays the current Mode used for the group (or sensor type).

  • AVERAGE: The gas concentrations from all sensors (of same type) in the group in a zone are averaged and

  • If the average is greater than or equal to the rising trip point, the zone outputs(s) are activated.

  • If the average is less than or equal to the falling trip point, the zone output(s) are de-activated.

  • If the average is between the two trip points, the outputs remain in their previous state.

  • VOTING: The number of sensors (of same type) in the group indicating a value greater than or equal to the rising trip point is counted.

  • If the count is greater than or equal to the QUORUM, then the zone output(s) are activated.

  • For zone outputs to be deactivated first the count of sensors (of same type) with value greater than or equal to the rising trip point should be less than quorum value and count of sensors (of same type) with value less than or equal to the falling trip point should be greater than or equal to the quorum.
    NOTE: Activating the output(s) is given priority if there is an equal number of sensors (of same type) with gas readings greater than or equal to the rising trip point and sensors (of same type) with readings less than or equal to the falling trip point.

  • QUORUM: It is up to the installer to ensure that the quorum entry is appropriate for the configuration. A value greater than the number of sensors being monitored by the group, stops the group from controlling the outputs. The default quorum value is 1. Select Quorum and hit Enter after Selecting Voting to change the quorum to values other than default value of 1.

The default sensor types and settings are as follows:

Description| Carbon Monoxide| Nitrogen Dioxide| Combustible Gas| Ammonia| Hydrogen Sulfide| Refrigerants| Carbon Dioxide (Type: 9)| Oxygen Depletion| Oxygen Enrichment| Carbon Dioxide (Type 10)
---|---|---|---|---|---|---|---|---|---|---

Table 4-2 – Sensor Default Settings

*The GROUP CONFIG. menu for Oxygen (SENSOR TYPE 8) has an additional option “O2 MODE” with available options: DEPLETION, ENHANCEMENT, BOTH. The Oxygen sensor can be configured to signal for:

1. High gas levels (ENHANCEMENT)
   Values equal to or greater than 20.9% v/v are only valid for Enhancement settings (Rising, Falling, Warning and Alarm).

2. Low gas levels (DEPLETION)
   Values equal to or less than 20.9% v/v are only valid for Depletion settings (Rising, Falling, Warning and Alarm).

3. High and low gas levels (BOTH)

If “BOTH” is selected for O2 mode, then panel will signal alarm, warning or zone activation for both oxygen depletion and enhancement. E.g. with default settings as indicated in Table 4-2 panel will indicate alarm condition for oxygen sensor reading of less than or equal to 19.5% vol as well as reading greater than or equal to 23.5% vol if “BOTH” is selected for O2 Mode. Whereas if “DEPLETION” mode is selected then panel will indicate alarm condition for reading less than or equal to 19.5% vol only and similarly if “ENHANCEMENT” mode is selected then panel will indicate alarm condition for reading greater than or equal to 23.5% vol only.

4.6.2.5 4-20mA OUTPUT or Analog Output
Menu path: Main Menu–>CONFIGURE SYSTEM? –>MANUAL CONFIGURE? –>CONFIGURE ZONES? –>ADD/EDIT ZONES–>420MA OUTPUT: –>
To assign 4-20mA output to a zone, select “4-20MA OUTPUT:” from the zone configuration menu and press ENTER. Then select “OUTPUT NUMBER:” and press ENTER.

Input the 4-20mA output number to assign it to the zone. Valid entries are 1, 2 and 3 and press ENTER. The display will return to the 4-20 O/P menu screen and show the currently assigned 4-20 mA output in the OUTPUT NUMBER field.
NOTE: A zone can be assigned only one 4-20mA output, and a 4-20mA output can only be assigned to one zone. 4-20mA output once assigned to a zone can be re- assigned to a different zone but cannot be deleted from the zone.

NOTE: Oxygen sensor readings is an exclusion for 4-20mA output i.e. its reading is not considered while computing output value for 4-20mA output.
Next, the output mode can be set to PEAK or SCALE.
PEAK – In this mode the gas reading active in the zone (except for the oxygen) corresponding to highest mA output is used to control the analog output assigned to the specific zone. In this case, any active gas reading, that is part of the zone will be taken in consideration, and the sensor reading corresponding to highest mA output will be  used to control the analog output. E.g. If a CO and NO2 sensor is assigned to a zone and CO Sensor reading is 50ppm (which corresponds to 8mA) and NO2 sensor reading
is 10.0ppm (which corresponds to 12mA) then 4-20mA or Analog output assigned to the zone will output 12mA.
SCALE – In this mode, the 4-20mA value for all detectors added to a zone are computed (for all sensor types except oxygen), and the output is the average of the 4-20mA value for all detectors assigned to the zone. E.g. If a CO and NO2 sensor is assigned to a zone and CO Sensor reading is 50ppm (which corresponds to 8mA) and NO2 sensor reading is 10.0ppm (which corresponds to 12mA) then 4-20mA or Analog output assigned to the zone will output 10mA.
To select the output mode for 4-20mA output, select OUTPUT MODE from the 4-20 O/P menu and press ENTER. Then, select PEAK or SCALE from the 4-20 O/P MODE menu and press ENTER. The display will return to the 4-20 O/P menu and the output mode selection will be updated as shown in Figure 4-29.
When the status of the zone is TROUBLE then 4-20mA output assigned to corresponding zone will switch the output to 20mA.

4.6.3 CONFIGURE RELAYS, H/S, BUZZER?
Menu path: Main Menu–>CONFIGURE SYSTEM? –>MANUAL CONFIGURE? –>CONFIGURE RELAYS, H/S, BUZZER? –>
The DVP-1200 includes 4 standard onboard relays with the option to add an additional 4 onboard relays. Additionally, remote relays can be added to the system. It also has an onboard buzzer and includes 4 outputs designed to operate standalone horn/strobe units. This section includes directions to configure those components.
From the CONFIGURE SYSTEM menu, select CONFIGURE RELAYS, H/S, BUZZER? and press ENTER. The display will show the CONFIGURE RELAYS, H/S, BUZZER? menu as shown in the images below.

4.6.3.1 CONFIGURE RELAY?
Menu path: Main Menu–>CONFIGURE SYSTEM? –>MANUAL CONFIGURE? –>CONFIGURE RELAYS, H/S, BUZZER? –>CONFIGURE RELAY? –>
To configure an onboard relay, follow the menu sequence as shown in Figure 4–30. With “RELAY:” selected, press ENTER.

Then, input the relay number to configure and press ENTER. The current relay configuration will be loaded and become editable as shown in Figure 4–32.

The following options are available for relay configuration:

• RELAY – Select the relay number to view settings and make changes.

• RELAY ON/OFF – Sets the selected relay to normally closed (ON) or normally open (OFF). Default value for this setting is
  OFF. Highlight this sub-menu and press Enter to change this configuration. Fail Safe operation can be implemented by configuring a relay to operate Normally ON, and wiring the circuit using the NC (normally closed) contact. In this way, if the control panel loses power the relay will activate the controlled device if it still has power.

• DELAY – Sets a delay between when conditions to activate the relay occur and when the relay activates. The time format is: [mm: ss]. Default delay time is 00:00. Highlight this sub-menu and press Enter to enter delay for the selected relay.

• MIN RUNTIME – Sets the minimum runtime once a relay is activated. The time format is: [mm: ss]. Default value is 00:00. Highlight this sub-menu and press Enter to enter minimum run time value for the selected relay.

• SET – The user must select SET to save the changes. The changes will become active as soon as the user selects SET.

ASSIGN ALARM RELAY
The user can assign a single relay to activate when an alarm condition occurs (regardless of zone). A relay assigned to ALARM will be dedicated to ALARM only and will not be shared with zones.
To assign a relay to ALARM, follow the menu as shown in Figure X. If any of the relay was assigned for Alarm, then it would be displayed in sub-menu “ASSIGN ALARM RELAY:”.

In the example below, relay 1 is assigned for the ALARM relay. After pressing ENTER, the display shows confirmation of the relay status. Enter “0” to set no relay as the alarm relay.

4.6.3.2 CONFIGURE REMOTE RELAYS
Menu path: Main Menu–>CONFIGURE SYSTEM? –>MANUAL CONFIGURE? –>CONFIGURE RELAYS, H/S, BUZZER? –>CONFIGURE REMOTE RELAYS?
To configure remote relays, follow the menu as shown in the images below. The user must first select DISCOVER REMOTE RELAYS before ASSIGN AND CONFIGURE REMOTE RELAYS becomes selectable.

Once the system has found remote relay, the screen shown in Figure 4-36 below will be display with address of remote relay. If DVP-1200 does not find any remote relay, then it will display NO RELAY FOUND in bottom box of the LCD. In this case it is recommended to verify the communication settings for Remote Relay in DVP-1200 matches with RR-24 unit in addition to verifying the wiring between RR-24 and DVP-1200.

After successful remote relay discovery, next step is to assign and configure remote relay. Relays 9 to 12 in DVP-1200 are reserved for remoted relays. Odd number relay (9 and 11) correspond to Relay 1 of the remote relay (RR-24) and even number relay (10 and 12) correspond to Relay 2 of the remote relay (RR-24). Remote relays can only be assigned to continuous relay number i.e. a remote relay can be assigned either Relay 9 and 10 or Relay 11 and 12. If only one remote relay is connected, then DVP-1200 will only allow to assign the connected remote relay to Relay 9 and 10. Follow the menu sequence as shown below to assign remote relay.

Following additional fail-safe settings are available for Remote Relay Configuration.

• FAIL SAFE ACTIVE/NOT ACTIVE
  With this setting one can either enable (FAIL SAFE ACTIVE) or disable (FAIL SAFE NOT ACTIVE) fail safe operation for corresponding remote relay.

• FAIL SAFE STATE ON or OFF
  This setting defines the state of the relay during fail safe condition if fail-safe settings is active or enabled.

• FAIL SAFE TIMEOUT (s)
  This is the time (in seconds) that the remote relay must wait for communication from the DVP-1200 before going into fail-safe mode if fail-safe setting is active (ON). Valid entries are 10 to 3600 seconds.

To change corresponding setting, highlight the line and hit Enter. Select the desired settings and hit Enter again. Once the desired configuration is selected for all fail-safe settings hit SAVE to save the settings and transfer the settings to remote relay.
Repeat the assignment procedure for second remote relay.
To configure Relays 9 to 12 for regular settings (delay, minimum run time etc.) use CONFIGURE RELAY? menu. Once remote relay is discovered and assigned then only corresponding relay number (9,10,11 and 12) will be valid entries for CONFIGURE RELAY menu.
4.6.3.3 CONFIGURE H/S
Menu path: Main Menu–>CONFIGURE SYSTEM? –>MANUAL CONFIGURE? –>CONFIGURE RELAYS, H/S, BUZZER? –>CONFIGURE H/S?
To configure a horn/strobe, follow the menu as shown in the images below. With “HORN/STROBE(S):” selected, press ENTER.
Then input the horn/strobe number to configure (H/S 1 is shown in the example below) and press ENTER.

Select CONFIGURATION and press ENTER. The current configuration for the selected horn/strobe will load and become editable as shown in the images below.

The following options are available for horn/strobe configuration:

• HS ON/OFF – Sets the selected Horn/Strobe to normally closed (ON) or normally open (OFF). Default value for this setting is OFF.

• DELAY – Sets a delay between when conditions to trigger the horn/strobe occur and when the horn/strobe turns on.
  The time format is: [mm: ss]. The default delay time is 00:00. To set the delay for the selected horn/strobe, highlight this sub-menu and press Enter.

• MIN RUNTIME – Sets the minimum runtime once a horn/strobe is activated. The time format is: [mm: ss]. The default minimum runtime is 00:00. To set the minimum runtime for the selected horn/strobe, highlight this sub-menu and press Enter. A horn would not normally require a minimum on time, but this parameter allows a more versatile configuration.

• MODE – The horn/strobe MODE can be set to CONTINUOUS(DEFAULT) or INTERMITTENT.

• ASSIGN TO ALARM/TRB – The horn/strobe can be assigned to activate during an ALARM, WARNING, or TROUBLE condition (regardless of zone). The default setting is NOT ASSIGNED(DEFAULT).

NOTE: A horn/strobe assigned to ALARM/WARNING/TROUBLE will be dedicated to that function and will not be able to be assigned to a zone.
• SET – The user must select SET to save the changes. The changes will become active as soon as the user selects SET.
4.6.3.4 CONFIGURE BUZZER
Menu path: Main Menu–>CONFIGURE SYSTEM? –>MANUAL CONFIGURE? –>CONFIGURE RELAYS, H/S, BUZZER? –>CONFIGURE BUZZER

The DVP-1200 includes an onboard buzzer. The buzzer is will activate during an ALARM, WARNING or TROUBLE condition. If the buzzer is activated, the user can press the HUSH button to silence it.
To configure the onboard buzzer, follow the menu as shown in Figure 4-37. Select CONFIGURE BUZZER? and press ENTER. The display will show the buzzer configuration options. It will also show the current buzzer configuration in the bottom box of the display.
The following options are available for the buzzer configuration:

• ON (CONTINUOUS) –During an ALARM, WARNING or TROUBLE condition, the buzzer will activate continuously. This is the default setting.
• ON (INTERMITTENT) – During an ALARM, WARNING or TROUBLE condition, the buzzer will activate intermittently (1 second on, 1 second off).
• OFF – This configuration will disable the functionality of buzzer and buzzer will not activate during any ALARM, WARNING or TROUBLE conditions.

4.6.3.5 TITLE 24?
Menu path: Main Menu–>CONFIGURE SYSTEM? –>MANUAL CONFIGURE? –>TITLE 24? –>

Figure above shows the Title 24 menu screen in DVP-1200. DVP-1200 features like occupied failure, unoccupied failure, calibration due and calibration overdue are enabled only when Title 24 is enabled in DVP-1200. By default, the Title 24 feature for the DVP-1200 is disabled. To enable Title 24, select line with TITLE 24 and press Enter, then select “Enable” and hit Enter.

By default, weekdays (Monday to Friday) 8 AM to 5 PM is configured as occupied time. Use “WEEKDAY START/STOP TIMES” and “WEEKEND START/STOP TIMES” to modify occupied period during weekday and weekend respectively. Up to two occupied period can be defined for weekday and weekend. DVP-1200 validates that Start Time is earlier than the End Time i.e., 9:15 AM as Start Time and 1:00 PM as End Time is a valid entry, but 10:00 PM as Start Time and 3:00 AM as End Time is invalid entry because 3:00 AM is earlier event in a day in comparison to 10:00 PM.

Time period outside of defined occupied period is considered as unoccupied time. Using “OCCUPIED PERIOD” menu selection you can selectively enable occupied period for WEEKDAY, WEEKEND or ALL WEEK. In Figure 4-43, “OCCUPIED PERIOD” has “WEEKDAY” selected which means only the time defined in “WEEKDAY START/STOP TIMES” will be considered as occupied time during a weekday. Even if there is time defined in “WEEKEND START/STOP TIMES” entire weekend time will be regarded as unoccupied time.
4.6.3.6 LOAD DEFAULTS?
Menu path: Main Menu–>CONFIGURE SYSTEM? –>MANUAL CONFIGURE? –>LOAD DEFAULTS? –>

4.6.5 VIEW SENSORS?
Menu path: Main Menu–>VIEW SENSORS–>

The VIEW SENSORS menu allows the user to view information about the sensors connected to the DVP-1200. Press the left/right cursor to scroll through the sensors. To select a specific sensor without scrolling, select “Sensor: x” and press ENTER. Then, enter the sensor address and press ENTER.
Sensor Description: Each sensor can be given a user defined description. The description is often used to describe the sensor’s location. To add or change a sensor’s description, select Sensor Description and press ENTER. A screen with sensor address, DESCRIPTION and SAVE will appear. Select ‘DESCRIPTION’ and hit ENTER. Then, use the alphanumeric keys to enter the description and press ENTER. Sensor description is limited to 20 characters. Use RIGHT arrow key to move to next character or to add a space and use DEL to delete last character entered. Once desired description is entered, SAVE the sensor description. Sensor Description entered for each sensor will be displayed in ALARM, WARNING and TROUBLE screen if corresponding sensor is one of the sources for the ALARM, WARNING or TROUBLE signal.

Disable: No – If any sensor is disabled, the panel will not take the sensor readings into consideration for Zone Outputs activation, panel fault conditions, etc. This is like a virtual delete.
When a sensor previously disabled is enabled back, then all the functionality related to the sensor is resumed back, i.e. sensor readings will be taken into consideration for Zone Outputs activation, panel fault conditions, etc.
This option allows the user to disconnect a sensor for repair or replacement without any trouble or error at the panel. For example, to replace a sensor, first disable that specific sensor in the panel. Then, disconnect it from the system and replace it with the new unit (of same type). Lastly, return to the VIEW SENSORS menu and enable the sensor. Using this method, all previous sensor configurations will be retained so it will not be necessary to reconfigure the sensor.
Delete – This will delete the sensor from the panel and from all the zone to which the sensor is added.
If the sensor is connected to the panel even after deleting it, then the panel must discover the sensor again. However, it will be like a new sensor discovery. Therefore, the sensor will not be added to any zones.
Note: When replacing a sensor (already registered with DVP-1200) with a sensor of different type but same address(e.g. CO sensor with address 17 replaced with NO2 sensor with address 17) then it is recommended to perform a Delete operation for corresponding sensor address, after sensor replacement is complete, and verify correct sensor type is displayed for corresponding sensor address.
Type: – Displays the sensor type. See Table 4-2 for a definition of each type.
The bottom box of the display shows the current gas reading of the detector. It also lists any zones the detector is part of. E.g. In following example, Sensor 1 is CO Sensor (Type: 1) reading 0ppm and is currently assigned to Zone

This information (COMPANY and PHONE) can be entered or edited by pressing ENTER in the TECHNICAL SUPPORT screen.

BACnet

5.1 General Information
When DVP-1200 boots, it is set by default to acquire the IP address using the DHCP client. For the BACnet the following information is important and will be necessary to configure the BACnet/IP client.

• Device Instance: 12345 (default)
• Port Number: 47808
• IP Address: Use the IP address being leased by the DHCP server (router). This information can be retrieved by checking ETHERNET SETTING in COMMUNICATION setting of the DVP-1200 connected to the network on the DHCP server. If static IP address is being used, use the one that was assigned to the DVP-1200.
• DVP-1200 BACnet/IP interface server, only allows the client to read values from DVP-1200. Writing is not allowed by the interface.

Following information about DVP-1200 are accessible via BACnet.

1. Group Settings (Range, Alarm, Warning, Rising, Falling) for each type of sensor for all Zones.
2. Readings and Type for all detectors
3. Zone Configurations (Types of detectors assigned, Horn/Strobe Assigned, Relay Assigned, Analog Output Assigned, Quorum for Voting Mode) for all Zones
4. Output status and values of DVP-1200 Outputs
5. Title 24 Configuration and Sensor Status

Note: BACnet Objects with value 65535 indicates the value received is not reliable. Some of the possible reasons for such a high value received are sensor not connected to panel, sensor is in trouble, or invalid/not supported BACnet object.
Operator must figure out the root cause of such readings.
For details on BACnet implementation or BACnet capabilities of DVP-1200, refer to DVP-1200 PICS available in product page in company website (www.macurco.com).
5.1.1 Group Settings for each type of sensor for all Zones
Information about Group Settings for each gas type can be accessed via BACnet output in DVP-1200. Table 5-3 shows the BACnet Object Type and Object Instance for each object. N in Table 5-3 refers to zone number. E.g. if I want to access the Alarm settings for CO sensor in Zone 3, then Object Instance for the corresponding object is 3+ (3-1) * 68= 139.
Group settings are local to zone and hence each zone can have different settings for same type of sensor. Table 5-1 shows the possible values for ‘code’ object and corresponding detector type. Similarly, Table 5-2 shows the possible values for ‘Eng.unit’ object and corresponding engineering unit.

Table 5-1 – Types of Detectors

Table 5-2 – Engineering Unit

Table 5-3 – BACnet Objects for Group Settings of all Zone
5.1.2 Readings and Type for all detectors
Each sensor addresses from 1 to 192 has two BACnet Objects (one for sensor reading and one for sensor type referred as group). Table 5-4 shows the BACnet objects and corresponding object instance. N in Table 4 refers to the sensor address.
E.g. to retrieve sensor reading for address 16, corresponding object instance is 553 + (16-1)*2 = 583.
If a sensor address is not detected by the panel, then corresponding BACnet object reading and group value will be 65535 and 0, respectively.
Note: If the value of sensor reading BACnet object is outside the range of detection of the sensor then the reading is not reliable and cause for unreliable reading must be investigated. Refer to Table 4-2 or sensor manual for information on rangeof detection.

Description| BACnet Object Type| BACnet Object Instance| Notes
---|---|---|---
Sensors[N] where N is from 1 to 192| reading| Analog value| 600+(N-1)2| e.g. To retrieve sensor # 16 reading, use 600+(16-1)2 = 630
type| Analog value| 600+(N-1)*2+1

Table 5-4 – BACnet Object for Detector Reading
5.1.3 Zone Configurations
(Types of detectors assigned, Horn/Strobe Assigned, Relay Assigned, Analog Output Assigned, Quorum for Voting Mode) for all Zones
Table 5-6 shows the BACnet Objects representing zone configuration for each zone. N in Table 5-6 refers Zone number.
When binary output is set to 1 (or active), it means that the corresponding DVP-1200 output (Horn/Strobe, Relay) is configured or assigned to that zone, or in case of the group[X] means that the sensor of type X (Table 5-1 lists the valid values of type i.e. value of X) is added to that zone.
If any of the three analog outputs are assigned to the zone, then object “analog output” for corresponding zone will have the analog output number (valid values are 1,2 and 3). If the zone does not have any analog (or 4-20mA) output assigned, then “analog output” will have value 0. “mode” BACnet object retrieves information about the mode for each sensor type in the zone. Value for mode is a 12-bit number. Bit 11, bit 10, and bit 6 are always set to 1. So, this field will have values from 3136 to 4095. If a sensor type has mode set to ‘VOTING’ in Group Configuration of the Zone, then its corresponding bit will be set to 1. And, if the sensor type has mode set to ‘AVERAGE’ then its corresponding bit will be set to 0. E.g., If Zone [1]. mode present value is 4095 then it means that all sensor types in Zone 1 are set to VOTING. Similarly, if Zone [2]. mode present value is 4094 then it indicates that all sensor types in Zone 2 are set to VOTING mode except Type 1 (CO) which is set to AVERAGE mode.

(Bit 8)| Type 8
(Bit 7)| Bit 6| Type 6
(Bit 5)| Type 5
(Bit 4)| Type 4
(Bit 3)| Type 3
(Bit 2)| Type 2
(Bit 1)| Type 1

Table 5-5 – Bit Assignment for Zone[N]. mode value
“quorum[X]” is another analog type object for Zone Configuration. If voting mode of operation for a sensor type X (Table 51 lists the valid values of type i.e. value of X) is selected, then value of this BACnet object represents quorum value for that sensor type.

Table 5-6 – BACnet Objects for Zone Configuration
5.1.4 Output status and values of DVP-1200 Outputs
When the output (buzzer, Horn/Strobe, Relay) is active the binary output value for corresponding output is set to 1 (active) and when the output is not active then the corresponding output is set to 0 (inactive).
For three analog outputs, the values of corresponding BACnet object represents the current output (in mA) from the analog or 4-20mA output in DVP-1200.
Table 5-7 shows the BACnet objects and corresponding Object Instance for DVP-1200 panel outputs.

Table 5-8 shows the BACnet objects with information relevant to Title 24 configuration and sensor status. Table 5-8 also shows the expected values for Title 24 Configuration BACnet objects.
Each CO sensor addresses from 1 to 192 has three BACnet Objects (Trouble, Fault and UntilCalDue) to communicate the status of the CO sensor status related to Title 24 feature. Table 5-8 shows the BACnet objects and corresponding object instance. N in the table refers to the sensor address. Following are the expected values for each of the three BACnet objects.

• Trouble
  0 – No Trouble
  5 – Trouble
  Possible reasons for trouble indicated by value of 5 are calibration overdue, calibration due feature disabled, and calibration period feature not supported by the detector.

• Fault
  0 – No Fault
  1 – Unoccupied Fault
  2 – Occupied Fault
  4 – Calibration Overdue
  8 – Calibration Due Warning
  16 – Calibration due feature disabled

• UntilCalDue
  255 – Calibration due feature disabled
  254 – Unknown calibration due value or value not transmitted by detector yet
  253 – Calibration due feature not supported
  241 – There are more than 30 days until calibration due
  1 to 240 – There are 30 or less number of days until calibration due
  0 – Calibration overdue
