Section 1 ­ Introduction
The FireNET Plus is an analog addressable fire alarm system that meets the requirements of UL 864 9th Edition.
1.1 Basic Features
The basic FireNET Plus control panel includes one SLC (Signaling Line Circuit) loop. The loop is capable of supporting 127 analog addressable points which can be any combination of sensors and modules. One additional SLC loop can be added to the panel increasing the analog addressable point capacity to 254. When analog sounder bases are used, the upper addresses 128 ­ 254 are allocated to increase loop capacity to 254 analog addressable points. This doubles the analog addressable point capacity of the panel. The combination of analog addressable points derived from sensors, modules, and sounder bases cannot exceed 800 addresses and sub-addresses maximum.
Up to 4.0 amps of power is available to drive the system, SLC loops, notification appliances, and auxiliary equipment.
Two Class B notification appliance circuits rated at 3.2 amps each (see Section 2.7 and 2.8 for additional details regarding NAC circuit ratings).
Three programmable Form C relays are built-in to the control panel.
500 network-wide zones for device and circuit grouping.
Analog Smoke Detector Features: Automatic Drift Compensation Maintenance Alert Adjustable Day/Night Sensitivity Calibration checking meets sensitivity test requirements of NFPA 72.
Auto-Learn utility identifies system devices, which makes initial system start-up easier.
An 8 line by 40 character graphic LCD display provides a flexible and intuitive operator interface (320 characters total).
Help screens are available from the front panel and annunciator user interface to assist in programming and operation.
512 additional points can be added to the system using the FN4127-IO 16 channel input/output boards. Each of these points can be programmed individually to be an input or low current output. These points are for secondary use only.

1.3 Limitations of Fire Alarm Systems
Follow Recommended Installation Guidelines: To achieve early fire detection, fire detection sensors should be installed in all rooms and areas of a house, apartment, or building in accordance with the recommendations of the National Fire Protection Association Standard 72 (NFPA 72), manufacturer’s recommendations, state and local codes, and the recommendations contained in Guide for the Proper Use of System Smoke Detectors, which is made available at no charge to all installing dealers. Generally, the standards and recommendations include the following (but installers should refer to the specific guidelines above before installing):
· Sleeping Rooms: Smoke detectors should be installed in every sleeping room. · Hallways: More than one smoke detector should be installed in a hallway if it is
more than 30 feet long. · At least Two Smoke Detectors: There should never be less than two smoke
detectors per apartment or residence. · Smoke Detectors in Alarm, Electrical, or Phone Locations: Smoke detectors
should be located in any room where an alarm control is located or an alarm control connects to an electrical source or phone line. If detectors are not so located, a fire within the room could prevent the alarm control from reporting a fire. · Notification Systems: All fire alarm systems require notification devices, including sirens, bells, horns, and/or strobes. In residential applications, each automatic alarm initiating device when activated should cause the operation of alarm notification device that should be clearly audible in all bedrooms over ambient or background noise levels (at least 15dB above noise) with all intervening doors closed. · Alarm in Every Bedroom and Level of Residence: A smoke detector with an integral sounder (smoke alarm) should be located in every bedroom and an additional notification device should be located on each level of a residence. · Maintenance: A maintenance agreement should be arranged through the local manufacturer’s representative and maintenance should be performed annually by authorized personnel only. To keep a fire alarm system in excellent working order, ongoing maintenance is required per the manufacturer’s recommendations and UL and NFPA standards. At a minimum the requirements of Chapter 7 of NFPA 72 (1999) shall be followed. · Test Weekly: The alarm system should be tested weekly to make sure all sensors and transmitters are working properly. The most common cause of an alarm system not functioning when a fire occurs is inadequate maintenance.
Alarms Cannot Guarantee Warning or Protection: Fire alarm system cannot guarantee warning or protection against fire in every potential situation. A study by the Federal Emergency Management Agency (an agency of the United States government) indicated that smoke detectors may not go off or give early warning in as many as 35% of all fires.
Limitation on Fire Alarm Effectiveness: A fire alarm system may not provide timely or adequate warning, or simply may not function, for a variety of reasons. For example:

FireNET Plus I & O Manual

v1.02

· No Detection: Particles of combustion or smoke from a developing fire may not reach the sensing chambers of smoke detectors because: 1. Barriers (such as closed or partially closed doors, walls, or chimneys) may inhibit particle or smoke flow. 2. Smoke particles may become cold, stratify, or not reach the ceiling or upper walls where detectors are located. 3. Smoke particles may be blown away from detectors by air outlets. 4. Smoke particles may be drawn into air returns before reaching the detector.
· No Multi-Floor Detection: In general, smoke detectors on one level of a structure cannot be expected to sense fires developing on another level.
· Insufficient Smoke: The amount of smoke present may be insufficient to alarm smoke detectors. Smoke detectors are designed to alarm, at various levels of smoke density. If such density levels are not created by a developing fire at the location of the detector, the detector will not go into alarm.
· Smoldering vs. Flaming Fires: Smoke detectors, even when working properly, have sensing limitations. Detectors that have photoelectric sensing chambers tend to detect smoldering fires better than flaming fires, which have little visible smoke. Detectors that have ionizing-type sensing chambers tend to detect fast flaming fires better than smoldering fires. Because fires develop in different ways and are often unpredictable in their growth, neither type of detector is necessarily best and a given type of detector may not provide adequate warning of a fire.
· False Alarms and Pre-Fire Disconnection: Smoke detectors are subject to false alarms and nuisance alarms and may have been disconnected by users. For example, a smoke detector located in or near a kitchen may go into nuisance alarm during normal operation of kitchen appliances. In addition, dusty or steamy environments may cause a smoke detector to falsely alarm. If the location of a smoke detector causes an abundance of false alarms or nuisance alarms, do not disconnect the smoke detector, call a professional to analyze the situation and recommend a solution.
· Fast Fires and Explosions: Smoke detectors cannot be expected to provide adequate warning of fires caused by arson and children playing with matches (especially within bedrooms), smoking in bed, violent explosions (caused by escaping gas, improper storage of flammable materials, etc.).
· Heat Detectors: Heat detectors do not sense particles of combustion and are designed to alarm only when heat on their sensors increases at a predetermined rate or reaches a predetermined level. Heat detectors are designed to protect property, not life.

FireNET Plus I & O Manual

11

firealarmresources.com

v1.02

· Unheeded Warning: Warning devices (including horns, sirens, and bells) may not alert people or wake up sleepers who are located on the other side of closed or partially open doors. A warning device that activates on a different floor or level of a dwelling or structure is less likely to awaken or alert people. Even persons who are aware may not notice the warning if the alarm is muffled by noise from a stereo, radio, air conditioner or other appliance, or by passing traffic. Audible warning devices may not alert the hearing impaired (strobes or other devices should be provided to warn these people). Any warning device may fail to alert people with a disability, deep sleepers, people who have recently used alcohol or drugs, or people on medication or sleeping pills.
· Strobes: Strobes can under certain circumstances, cause seizures in people with conditions such as epilepsy.
· Drills: Studies have shown that certain people, even when they hear a fire alarm signal, do not respond or comprehend the meaning of the signal. It is the property owner’s responsibility to conduct fire drills and other training exercises to make people aware of fire alarm signals and instruct on the proper reaction to alarm signals.
· Hearing Loss: In rare instances, the sounding of a warning device can cause temporary or permanent hearing loss.
· Telephone Transmissions Problems: Telephone lines needed to transmit alarm signals from a premises to a central station may be out of service or temporarily out of service. For added protection against telephone line failure, backup radio transmission systems are recommended.
· System Failure With Age or Lack of Maintenance: System components, though designed to last many years, can fail at any time. As a precautionary measure, it is recommended that smoke detectors be checked, maintained, and replaced per manufacturer’s recommendations.
· Electrical Power Problems: System components will not work without electrical power. If system batteries are not serviced or replaced regularly, they may not provide battery backup when AC power fails.
· High Air Velocity or Dusty or Dirty Environments: Environments with high air velocity or that are dusty or dirty require more frequent maintenance.
Importance of Maintenance: In general, fire alarm systems and devices will not work without power and will not function property unless they are maintained and tested regularly.
Alarm is Not Substitute for Insurance: While installing a fire alarm system may make the owner eligible for a lower insurance rate, an alarm system is not a substitute for insurance. Property owners should continue to act prudently in protecting the premises and the people in their premises and should properly insure life and property and buy sufficient amounts of liability insurance to meet their needs.

Section 3 – Power Supply and Main Control Unit Connections
3.1 AC Power Connection
The AC power connection terminal block is located in the lower right hand corner of the control board (when viewed from the front, see Figure 3.1). Observe the wiring polarity and connect as shown. Local electrical codes may require that a licensed electrician make these connections.
NFPA 72 requires that the AC connection be made from a dedicated branch circuit that is mechanically protected. The circuit must be marked in red and identified as a “FIRE ALARM CIRCUIT”. The location of the circuit and its disconnecting means shall be permanently noted at the fire alarm control panel. The circuit breaker must be rated at 20 amps maximum.
Fuse Replacement: To replace the power supply fuse F7, power down the fire system by removing the AC power first, then disconnect the backup batteries to the fire alarm control panel. Remove the blown fuse and replace with a 3A 250VAC, slow blow, 5X20mm fuse. When the fuse replacement is completed, restore AC power to the control panel and connect the backup batteries observing polarity of connections.
3.2 Battery Connection
The FireNET Plus fire alarm control panel can charge up to 60AH batteries maximum. Use the current draw and battery calculation worksheet in section 2.6 to determine the correct battery size to use.
The battery leads connect to the battery terminal block located at the lower left-hand corner of the control board (when viewed from the front). Connect two 12-volt batteries in series to the battery leads as shown in Figure 3.1. Both batteries must be of the same AH rating. Do not try to parallel multiple batteries together to obtain a higher AH rating. Use only UL Recognized Sealed Lead Acid Batteries.
Fuse Replacement: To replace the in-line battery fuse, remove the battery lead (BLACK) from the negative battery terminal and twist the bayonet fuse holder to open. Remove the blown fuse and replace with a “Bussman AGC-10” (10A) type fuse or equivalent. Reassemble the bayonet fuse holder and attach the battery lead to the negative terminal of the battery.
NOTE: The standby batteries cannot power the system until the main 120VAC power has been established. Once the system has been initially powered from them 120VAC source the batteries will operate the system in the event of a power failure.

4.2.2 Addressing
Up to 32 RS485 bus devices can be added to the system. Each RS485 bus device must be set to a unique address 1-32.
The address for each RS485 bus device is set using a position DIP-switch in binary fashion. Switches 1-5 represent the values 1, 2, 4, 8, and 16, respectively. Switch 6 is not used. To set the address, move only the switches whose values when added equal the address value you wish to set to the “ON” position. For example, moving switches 1 and 3 (whose values are 1 and 4 respectively) to the “ON” position sets the address of 5 into the RS485 bus device. See the other examples below:

4.3 FN-4127-IO – Input / Output Board
In addition to the basic 254 points that the FireNET Plus can accommodate on the SLC loops, additional input and output points can be added by using FN-4127-IO Input/Output boards on the RS485 bus.
The FN-4127-IO has 16 channels. Each channel can be individually configured as either an input or an output. Up to 32 FN-4127-IO boards can be connected to the system via the RS485 bus giving the system an additional 512 inputs/outputs.
4.3.1 Configuring Inputs
Inputs to the FN-4127-IO are optically isolated and connected to the board by installing a normally open contact with a resistance no greater than 500 ohms to any input and a terminal marked 0V. The current switched by the contact will be a maximum of 3 milliamps.

NOTE:

Inputs on the I/O board are not supervised. These inputs are not for primary initiating or detection of fire or life safety conditions. These inputs are programmable for secondary use only, and not used for signaling Fire, Supervisory, or Trouble conditions. All primary initiating or detection inputs must be connected to applicable SLC devices listed for fire. See Section 5 of this manual for SLC devices.

FireNET Plus I & O Manual

firealarmresources.com

v1.02

4.3.2 Configuring Outputs
When configured as outputs, the I/O board channels supply a negative voltage (with respect to the I/O board 24V power supply) via a transistor.
Because transistor elements can be damaged by excessive current drain, great care should be taken when connecting to outputs. Particular care should be taken to ensure that suppression diodes on relay coils are correctly polarized. Wrongly connected diodes will damage the outputs. Diodes should be connected with the band to the positive 24V.
2.2k
Individual channels can supply current up to 100 milliamps but this must be limited to 500 milliamps for each bank of eight (500 milliamps for 1-8 and 500 milliamps for 9-16). The power supply to the I/O board should also be considered to ensure that its rating is not exceeded if multiple channels are switched on. Overall current draw for the I/O board is 1010mA max.

NOTE:

Outputs on the I/O board are not supervised. These outputs are not for primary notification of fire conditions (i.e. not for use as NAC circuits). These outputs are for secondary use only. All primary notification output devices must be connected to applicable NAC circuits on the FireNET panel. See Section 3.4, Appendix A, and B for details on NAC circuits and compatible NAC devices.

When powering the I/O board from the FireNET Plus auxiliary 24VDC power (limited to 360ma), the following maximum wiring distances apply at the gauges noted:

Wire 18AWG 16AWG 14AWG 12AWG

Distance 875ft 1400ft 2300ft 3700ft

When powering the I/O board from a separate Aux 24VDC UL Fire listed supply the maximum voltage drop cannot exceed 4VDC.

I/O CHANNEL

4.3.3 LED Indicators
LED indicators on the I/O board give some simple diagnostic information and show that the boards are communicating with the control panel. The red LED (LED1) is on during receipt of a message from the control panel.
· If the LED is flickering more or less continuously – the board is operating normally.
· If this LED is not lit – the board is not receiving data from the control panel and the comms connection should be checked.
· If this LED is permanently lit – then it is likely that data is being received but that it is being corrupted. In this case the quality of the comms connection should be checked for interference from mains or other noise generating sources.
The yellow LED (LED2) will flicker briefly every few seconds when the I/O board responds to the main panel. If this LED does not flicker then it is not responding to the control panel and the comms connection should be checked.

5.4 Addressing Devices
Prior to installation, all of the addressable devices installed on the FireNET Plus SLC loop must be programmed with a unique address ranging from 1 to 127. The analog sounder bases will automatically derive their address from the host sensor (detector) attached to them. The ASB address will be the sensor address

• 127 (i.e. N + 127). Example: The sensor address is 36. 36 +127 = 163. The ASB will have an address of 163. This address is what the FireNET Plus control panel uses to identify each addressable device and control its functionality. All Hochiki addressable devices come from the factory preset to address 127. This preset address can be reprogrammed using the Hochiki TCH-B100-NS programmer. Follow these instructions to set/reprogram the address.
  1. Identify each analog addressable device that will be installed on the SLC loop and label it with a unique address ranging from 1 to 127.
  2. Using the Hochiki TCH-B100-NS programmer as shown in Figure 5.4, program the appropriate address into each analog addressable device.

The Hochiki DIMM Dual Input Monitor Module is designed to work with pull stations, water flow switches, and other applications requiring the monitoring of dry contact alarm initiating devices. The DIMM can monitor two independent inputs with discrete reporting, yet the module only requires a single address on the SLC Loop. A typical example would be for use with a waterflow and tamper application. One input would be connected to the waterflow switch for a fire alarm condition. The second input would be connected to the tamper switch for a supervisory condition. A single DIMM module would be used instead of two single input modules such as the FRCME. The DIMM inputs operate in a similar fashion to the FRCME input. Refer to the installation instructions included with the DIMM for more detailed wiring and installation instructions.

5.15.1 Class A Operation
The SCI should be located within 5 feet of the FireNET Plus control panel on both the outgoing and incoming SLC loop legs. In addition an SCI should be located between every SLC loop detector and module as shown in figure 5.15.2 and is required for NFPA 72 Class A Style 7 compliance. For Class A Style 6 compliance the SCI modules may be located at strategic locations based on the installer’s or system designer’s discretion.
In the event of a short circuit on the SLC loop the 2 SCI modules adjacent to the short (closest SCI on the left and the right of the short) will activate and its LED will turn on. All the devices between the two SCI modules will be isolated and inoperative. All other devices on that SLC loop will remain operational. The FireNET Plus control panel will indicate a trouble condition. When installing SCI modules for true Style 7 compliance, the SCI modules must be installed in a “closed nipple” fashion (see Figure 5.15.2). By using this method, no devices are lost from a single short on the SLC Loop.

6.1.1 FN-4127-NIC Network Interface Card

To enable control panels to be connected together as a network, a network card must be installed in each panel. This card connects to the FireNET Plus on the rear of the main control board and is held in position by two M3 screws. If an FNP-1127-SLC expander card has been installed, the network card must be mounted on top of the FNP-1127-SLC expander.

FN-4127-NIC Network Card

Panel PCB (rear side) M3 Screws

FNP-1127-SLC Expander Board (may be installed)

To install a network card, the AC and battery power must first be switched off. Next, the display panel must be opened to expose the back of the circuit board. The network card can then be plugged into the two connectors on the top left of the control board PCB (or plugged into the connectors on the FNP-1127-SLC card, if installed). The network card must then be secured in position with the M3 screws.

OBSERVE STATIC PRECAUTIONS WHEN HANDLING CIRCUIT BOARDS!

Each network node must be allocated a unique network address. This is done by setting the DIP switches on the network card to the required binary number as shown above. It is important that each node has a different address for correct operation so care must be taken to set and record the network card address for each panel. Always set the address on the DIP switches with power to the panel switched off.

6.1.1.1 Cable Length
The FireNET Plus network communications protocol has been designed to be extremely tolerant to interference and data corruption; however as with any system, limitations must be set to guarantee correct operation. The specified transmission distance limit for the communications method used is 4000 ft. (1200m) and because the data is re-transmitted at each network card, in theory, there can be 4000 ft. (1200m) between each card if required. The minimum cable size for the FireNET Plus network is #20 AWG. The network communications uses RS485 technology.
Using the above cable distances however, does not take into account the failure of a network card to communicate with the system through total power failure or a card trouble. In this situation, the network card would disconnect itself from the network and connect the network cable such that it bypasses the card in question. This means that the total cable length between the cards either side of the disconnected one could be 8000 ft. (2400m), which is outside of the specification for the communications method used (RS485). This trouble scenario could clearly be extended to more network cards and this would add 4000 ft. (1200m) of cable length in each case.
A sensible trouble tolerance limit must therefore be suggested to enable the performance of the system to be predicted. Because of the nature of the fire protection system, its design is biased towards inherent reliability and failure of a network card, although possible, is very unlikely. Fire control panels also have substantial back up power systems. Therefore, the likelihood of a total power failure under operational conditions is also extremely rare. A suggested tolerance level of one card failure is therefore recommended. To guarantee operation of the system with one card failure it is necessary to arrange the network so that a failure will not introduce more than 4000 ft. (1200m) of cable between the two cards, which would be connected together by the failure. This means that the total cable length between adjacent nodes should not be more than 4000 ft. (1200m). It is not important how the 4000 ft. (1200 meters) is made up i.e. it could be 350 ft. (100m) and 3650 ft. (1100m) or 2000ft. (600m) and 2000ft. (600m).
Using these general rules and the specified or equivalent cable types will provide a guaranteed performance of networks with plenty of tolerance.

When designing or installing a network of FireNET Plus panels, always be aware of the following:
1. The panel network must be wired as a ring (Class A). 2. There should be no more than 4000 ft. (1200m) maximum cable length between two
adjacent segments. 3. A short circuit at Point A will automatically disconnect the shorted section and
announce a trouble condition at all panels but the entire network will continue communicating. 4. A short circuit at Points A and B will automatically disconnect both sections and announce a trouble at all panels. Communication will continue where a connection exists; in this case, a network will be maintained between panels 1, 3 and 5, while another network will be maintained between panels 2 and 4. 5. Open circuit troubles should allow the network to continue operating in the same way as short circuit troubles. 6. Network cabling should be standard RS485 type for up to 64 nodes. 7. The minimum cable size for the FireNET Plus network is #20 AWG.

6.1.1.3 Cable Type
The cable type used for the network connection should be suitable for RS-485 applications. Minimum wire size should be 20ga. twisted, shielded, stranded. RS485 communications cable is typically standard Class 2 communications cable. However, depending on the AHJ, FPL or FPLR cable may be required. Follow local jurisdictional and AHJ requirements. NFPA 70 national electric code compliance may be required for network cabling depending on local jurisdiction, AHJ, regulations, and/or codes.
6.1.1.4 Proper Shield Termination of the Network Cable
In many installations, interference from RFI, EMI or other noise sources can create problems. In order to reduce the effects of such noise, terminate the shield to the earth ground terminal block in the main control panel. DO NOT ground the shield at both ends of the cable!

6.1.1.5 Connecting the network cable
All panels will have two cables connected to another panel or panels. If either of these is not connected a trouble condition will be displayed. The connection is polarity sensitive. The + and ­ from one panel must connect to the + and ­ of the next panel and so on. The temperature of the cable should not exceed 131 degrees F (55 C).

NOTE:It is important to ensure that the connection from the OUT+ from one panel connects to the IN+ terminal of the next and the OUT- from one panel connects to the IN- of the next panel and so on.

7.3 Access Level 2 Operations
The following operations can only be done after the panel is placed into Access Level 2 operating mode. To place the FireNET Plus into Access Level 2 follow these instructions:
7.3.1 Entering Access Level 2
1. Press any navigational arrow key to enable the panel. 2. Using the arrow keys enter the 5 digit code. Digit values are 1 – 4 only and
correspond to the value on each arrow key. (Up = 1, Right = 2, Down = 3, Left = 4) The factory default for the Access Level 2 code is 22222. 3. Press the Enter key. The front panel graphic display will confirm you are in Access Level 2. 4. If there is no activity for 120 seconds on the front panel controls once the system is in Access Level 2 operating mode, the system will time out and revert back to Access Level 1 operating mode automatically. 5. You may also use the Enable Access keyswitch on the front of the panel to enter Access Level 2. Simply insert the key and turn it to the right. The panel display will confirm that you are in Access Level 2.
NOTE: The FireNET Plus panel will NOT time out to Level 1 when using the key. Be sure to return the key to the OFF position and remove it when not in use!
7.3.2 Silencing an Alarm
To silence an alarm condition place the panel into Access Level 2 operating mode as described in 7.3.1. Press the “Alarm Silence” button. The “Alarm Silence” button acknowledges any current alarm conditions and typically silences any audible and visual notification appliances such as horns and strobes. In some cases the system may be programmed so that the “Alarm Silence” button silences the audible notification appliances but allows the visual notification appliances such as strobes to remain flashing. Your system installer can inform you how your system is set up to operate. After an alarm has been silenced, the flashing fire LED’s will go steady, and “alarm silenced” will display in the upper right corner of the LCD display.
7.3.3 Resounding an Alarm
To resound an alarm condition place the panel into Access Level 2 operating mode as described in 7.3.1. Press the “Resound Alarm” button. Pressing the “Resound Alarm” button will reactivate any audible or visual notification appliances that were previously silenced using the Alarm Silence operation.

7.3.4 Resetting an Alarm
Once a fire or other alarm condition has been verified and cleared it is necessary to reset the panel. To reset the FireNET Plus, place the panel into Access Level 2 operating mode as described in 7.3.1. Press the “Reset” button. All latched outputs such as relays used for elevator recall will return to their normal state.
Prior to resetting the panel it is necessary to clear the condition that caused the alarm. For example, if a manual pull station was activated to cause the alarm, that manual pull station must be physically reset in order to reset the panel. If you attempt to reset a panel that has an existing alarm condition that has not been cleared, the panel will go back into alarm immediately after trying to reset.
7.3.5 Initiating a Fire Drill
To initiate a fire drill, place the FireNET Plus panel into Access Level 2 operating mode as described in 7.3.1. Press the “Fire Drill” button to engage fire drill mode. The fire drill activates NAC and SOM indication circuits, but does not activate fire relays, R2M, programmable relays, etc. A subsequent press of the fire drill button will deactivate fire drill mode. Any actual fire alarms during a Fire Drill will automatically override fire drill mode.
7.3.6 Silence the Panel Sounder
Many system conditions such as system troubles will activate the sounder in the FireNET Plus control panel. The user can silence the panel sounder by pressing the “Panel Sounder Silence” button on the front panel. This silences only the panel sounder. Other audible outputs such as horns or strobes require a different operation to silence.

Figure 7.4 Main menu items at Access Level 2
Once this menu is displayed you can scroll up or down using the navigational arrow keys to highlight each of the six menu options. A menu option is highlighted when a triangular arrow symbol appears to its left.
Each menu option may be selected by first highlighting it using the up/down arrow keys, then pressing the right arrow key to select. The six Access Level 2 Main Menu option functions are described in the following sections.

7.4.2 Disablements
The Disablements menu allows the user to disable individual points, circuits, zones, or loops on the FireNET Plus fire alarm system. This is typically done while the system is being serviced or tested or to temporarily remove a faulty system device. CAUTION: Any portion of the system that is disabled will not report an alarm condition.
All disablements have two options, timed or untimed. For disablements up to 24 hours in length the timed disablement option should be used. This will prompt the user to enter a disablement time in 30-minute increments from 30 minutes to 24 hours. Once the disablement begins the panel will countdown the selected disablement time. When the time expires the disablement is cancelled automatically.
Untimed disablements should be used only when it is necessary to disable a portion of the system for over 24 hours. Untimed disablements remain active until they are manually reset at the panel through the Access Level 2 Main Menu / Disablements command.
Once you select timed or untimed disablement you can choose to disable loops, zones, addresses, NAC, or I/O circuits through sub-menus to the Access Level 2 Main Menu / Disablements option.

v1.02

As previously discussed highlighting the desired menu option and then pressing the right navigational arrow selects that option. Pressing the left navigational arrow at any time backs out of the current menu returning to the previous menu.
Note: The FireNET Plus fire alarm system will indicate a disabled condition any time there is an active disablement on the system, via LCD display text and the “point bypassed” LED on the front panel. Any item disabled is considered an off-normal condition and will generate a general trouble condition until the disabled item is returned to normal.
7.4.2.1 Disabling Loops
The Disable Loops sub-menu option to Disablements, allows you to disable an entire SLC loop with one command. The SLC loop may contain up to 127 analog detectors and addressable input and/or output modules, as well as up to 127 analog sounder bases. Disabling an entire SLC loop disables all inputs and outputs on the loop and should be used only in extreme cases such as a service related problem affecting all the devices on the SLC loop.
WARNING: Loop disablement does not electrically isolate the panel from the SLC loop wiring. The SLC loop should be disconnected from the panel before any diagnostic testing is performed.
Disabling Zones
Each device on the system is assigned to a zone by the system installer. A zone may consist of one or many points. Disabling a zone disables all the points assigned to that zone.
Disabling Addresses
Each SLC loop device on the system is assigned a unique address. In some cases an SLC loop device may have sub addresses as well. Using the Disable Address sub-menu command the user can individually disable any single address on the system.

v1.02

Disabling NAC Outputs
The disable Audible Device output sub-menu option allows the user to disable all of the local NAC, SOM, and ASB outputs on the system. This is typically done for periodic tests so the building occupants are not disturbed while activating each alarm device. When you choose this option all of the notification appliances connected to the panel notification appliance circuits and SOM modules are disabled, as well as any analog sounder bases.
Disable Panel I/O
The Disable Panel I/O sub-menu option allows a user to disable an individual panel input or output. This includes individual notification appliance (NAC) circuits, on-board panel relays, and the programmable function button. This option applies only to on-board inputs and outputs ­ SLC loop devices must be disabled by using the Disable Addresses option.
View & Restore Disablements
The View & Restore Disablements sub-menu option is used to quickly display any system disablements and optionally reset them to normal. Scroll to the View/Restore Disablements sub-menu option, press the right navigational arrow to select, and then follow the prompts on the panel display to view/reset any disablements on the system.
7.4.3 View Devices
The View Devices menu option allows the user to view every SLC loop device. For each device the panel display will indicate the device type, zone, and location text. In addition, analog devices such as smoke and heat detectors will also be displayed with their current analog value. This analog value can be useful in determining if a smoke detector requires cleaning. Photoelectric detectors also display in terms of obscuration (%/ft) and the heat detectors in terms of temperature (F°).
For non-analog input devices the current status will be displayed as Off or On. For nonanalog output devices the current status will be displayed as either Off or Activated. Service personnel who want to verify system devices and troubleshoot potential problems typically use the View Devices sub-menu option.
7.4.4 Test Zones
The Test Zones sub-menu option is used by service personnel to quickly and easily perform periodic system tests. Please refer to the testing and troubleshooting section of this manual for a more detailed explanation. This feature is typically referred to as a “One Man Walk Test.”

7.2 Phone Line and Phone Number Selection
The FireNET Plus DACT can be configured with up to four account numbers and four phone numbers. Each phone number corresponds to an account (phone number 1 is used with Account 1; phone number 2 is used with Account 2, etc). This allows for programming of backup and duplicate reporting configurations.

Events are communicated to each account in order and by priority beginning with Account 1. The communicator will begin the dialing sequence using phone line 1, unless phone line 1 has failed. If the communicator cannot report events successfully using phone line 1, it automatically switches to phone line 2.

Account 1 and account 2 are used together for primary and backup reporting. If duplicate reporting is needed, account 3 may be used, with account 4 serving as its backup. Table 7.2 shows how the accounts and phone lines are selected when reporting an event (both phone lines in normal working condition).

Since the communicator selects the phone line to be used, both lines must use the same dialing sequence. If one phone line requires that a “9” be dialed, it cannot be used with a second line that does not require a “9”.
NOTE: Ground Start phone lines must not be used.
NOTE: Call Forwarding must not be used.
7.2.1 Test Report: The test report is sent using alternating phone lines once every 24 hours. All attempts to communicate the test report will be made on one phone line, even if that line is not working. The next test report is sent using the other phone line. This complies with UL and NFPA requirements for digital alarm communicators.
NOTE: If the central station only receives every other test report (i.e. every other day), this is an indication that the communicator is unable to report using one of the phone lines. Investigate and correct the cause of this condition immediately.
7.3 Phone Line Supervision
The FireNET Plus supervises both telephone lines for the presence of normal line voltage. Each line is checked every 10 seconds. If trouble with a phone line is detected, the FireNET display will indicate the trouble condition. The phone line failure can be communicated to the monitoring station using the other phone line, unless it has also failed.
Normal phone line voltage is approximately 48 VDC. The panel will detect a trouble condition when the phone line voltage falls below 4 VDC.
NOTE: Since the FireNET Plus samples voltage to test the telephone lines, it cannot recognize a non-working phone line that has normal voltage present.
NOTE: The FireNET Plus does not supervise the telephone lines while it is communicating.

7.4 Report Groups
The FireNET Plus has five report groups that can be selected to maximize the reporting options. Each group includes specific types of events that will be reported. The report groups are selected by account, with account 2 and 4 also having a selection for backup reporting. The report groups and events associated with them are shown below:
Alarms ­ · Fire Alarm · Waterflow Alarm · Fire Drill
Alarm Restore ­ · Fire Alarm Restore · Waterflow Alarm Restore · Fire Drill Restore
Supervisory, Trouble, Enable/Disable ­ · Supervisory (Activation and Restore) · All Trouble Conditions (Activation and Restore) · Pre-Alarm (Activation and Restore) · Auxiliary (Activation and Restore) · Smoke Detector Maintenance Trouble (Activation and Restore) · Disable and Enable Events · Loop Explorer Programming Event (local and remote)
Service / Test ­ · “Test Zones” · Device Tested · Test Report
System Reset ­ · Alarm Silence Event · Reset Event
Backup Report (Account 2 and 4 Only) · Account 2 and 4 can be selected to report to the associated phone number as a backup of the primary account. For this feature, account 1 is considered the primary account, with account 2 being its backup. Account 3 serves as a second primary, or duplicate account, with account 4 being its backup.
If communication is not established to the primary account after the first five attempts, the backup account will be used. Please see section 7.2 for additional details.
By default, all report groups are selected for each account. If it is necessary to change the groups selected for a particular account you must use the Loop Explorer software programming tool.

7.5 Communication Failure
If all attempts to communicate to an account fail, the FireNET Plus will display a “Comms Fail” trouble condition, along with the number of the account that failed (1 ­ 4). The original event will be removed from the report queue. If there are additional events to be reported the panel will attempt to report them, along with a communication failure event. The panel will remain in a “Comms Fail” trouble condition, but the FireNET Plus will attempt to report any new events while in this state.
To clear the “Comms Fail” trouble from the panel display, press the panel Reset button. This action wil
