INSTALLATION GUIDE

CM705B – Universal Expander Module

The CM705B universal expander provides a cost effective way to increase the control panels zone inputs, programmable outputs and power supply capacity using a single expander module. This module is extremely useful when the system is comprised of multiple areas, as an expander can be located in each area providing power, siren and strobe outputs and up to 16 zone inputs.

Figure 1: CM705B Comparison With Discrete Modules

The universal expander is available in a metal cabinet (CM705B) or as a PCB module only (CM705BP) depending on your requirements. The module connects to the control panel via the 4-wire encrypted RS485 LAN, and must be assigned a unique address on the LAN via the address DIP switch. See “Module Addressing” on page 3 for more details.
Dedicated service keypad and tamper inputs are provided. If the tamper input is not required, then you should disable it by fitting the supplied shunt to the tamper input.

Programming Considerations

The universal expander does not need to be enabled via panel programming. The control panel will recognise the module after a system power cycle or you can use the LAN scan command to force the system to scan for new modules connected to the LAN network without powering down the system. The LAN must be in the unsecured state or the system will not find new modules.

The EOL resistor value programmed in the control panel is common for all hard wired zones connected to the panel and each universal expander.

Zones on the universal expander must be programmed with a valid zone type before they become available for use.

At factory default, zone inputs 17 and higher are set as ‘Not Used’.

Outputs on the universal expander must be programmed as a valid output type before they become available. At factory default, outputs 9 and higher are set as ‘Not Used’.

Refer to the control panel installation manual for specific zone and output programming information.

LED Indicators

The universal expander includes four LED indicators that provide feedback and trouble shooting information at the module. Various information is also provided at the system keypad via the device status menu.

ex- pander is OK.
MAINS| On| Indicates that the A.C. mains voltage is connected.

Table 1: LED Indicator Descriptions

Module Addressing

A five way dip switch is used to set the universal expander address on the system (currently switch 5 is not used). The module’s address setting determines which zone and output numbers will be available.

The universal expander is like having 1 x CM704B zone expander, 1 x CM710B output expander and 1 x CM720B power supply module all in one and as such each universal expander added to the system will consume the corresponding single function modules address. For example if the universal expander is assigned to address 4, then you cannot assign a CM704B, CM710B or CM720B module to address 4.

When Single EOL or Alarm + Tamper EOL options have been configured the first 8 zones are available on the con-trol panel zone terminals. If Split EOL monitoring is selected the first 16 zones are available on the control panel zone terminals.

On panels with zone capacity greater than 16, each CM705B universal expander module on the system will occupy 16 zones regardless of the EOL resistor option selected. This means that when configured in Single EOL or in Alarm + Tamper mode each CM705B expander will provide 8 physical zone inputs only with an additional 8 zones which do not have any physical inputs. These spare zones can be assigned as RF zones, or you can install the optional CM707B plug on zone expander which provides an additional 8 hard wired zone inputs.

When Split EOL monitoring is selected each CM705B expander will provide 16 physical zone inputs and no spare inputs are available.

Single EOL Monitoring

If single EOL resistor option has been selected and one CM705B universal expander has been installed at address 1, the system will provide zones 1 to 8 on the main panel and then zones 17 to 24 on the expander module.
In this configuration there is no physical input for zones 9 to 16 or zones 25 to 32 however these spare zones could be assigned as RF zones if an RF receiver has been installed.

Split EOL Monitoring

If the Split EOL resistor option has been selected and one CM705B universal expander has been installed at address 1, the system will provide zones 1 to 16 on the main panel and zones 17 to 32 on the expander module. In this con- figuration each zone has a physical input available and there are no spare zones available.

Alarm + Tamper Monitoring

If the Alarm + Tamper monitoring EOL resistor option has been selected and one CM705B universal expander has been installed at address 1, the system will provide zones 1 to 8 on the main panel and then zones 17 to 24 on the expander module.
In this configuration there is no physical input for zones 9 to 16 or zones 25 to 32 however these spare zones could be assigned as RF zones if an RF receiver has been installed or you can install the optional CM707B plug on zone expander which provides an additional 8 hard wired zone inputs.

RF Zones

If an RF receiver has been installed, then all zones up to the maximum number supported by the panel become avail-able for use.
Each RF zone can be assigned or mapped to either a physical or spare zone input allowing zone parameters to be programmed. Assigning an RF zone to a physical zone will override or ignore the zones physical hardware input terminals.

The control panel will need to be power cycled for the new volume settings to take effect.

Table 2: CM705B Address Configuration On Solution E Series and Vision X Panels

Address switch 5 is reserved for future use. You should leave this set to the off position when configuring the Solu-tion E Series and Solution 144 panels.

Zone Wiring

Each CM705B universal expander installed on the system will be assigned a bank of 16 zone inputs regardless of the EOL resistor value programmed in the control panel.

When the end of line resistor value is set for single EOL or Alarm + Tamper, an optional CM707B Piggy Back Zone Input Expander Module can be fitted to the universal expander to allow an additional 8 zone input terminals. If the CM707B Piggy Back Zone Input Expander Module is not fitted, only the first bank of 8 zone inputs assigned to the universal expander can be hard wired and the second bank of 8 zones can only be utilised by an optional RF receiver and RF sensors.

EOL Resistor Colours and Values

The universal expander is supplied with two values of EOL resistors to suit all possible wiring configurations. The resistors are colour coded as per below.

CM705B Zone Input Allocation

The following table outlines the zone allocation for each universal expander module when using single EOL, alarm + tamper or split EOL. It also shows the effect on zone numbering when the optional CM707B is installed.

Programming

Output programming options are fully detailed in the control panel installation manual and quick reference guides. The following sequence outlines the correct output programming procedure.

1) Program the Output Name
Output names are used to simplify programming, user interaction and reporting.
2) Select the Output Event Type
Over 60 different event types are available to suit a variety of applications.
3) Program the Output Event Assignment
Assigns the output to a specific user, zone, area or door assignment etc.
4) Select the required Output Polarit y
Configures how the output behaves (eg. operates for fixed period of time, pulses etc).

5) Program the Output Time Parameter
Sets how long the output will turn on or off for.
6) Select any required Output Options
Defines various options including to display or not display a trouble event when the output device is missing etc.

Power Supply

The CM705B universal expander module includes a 13.8V DC, 1 Amp power supply that can be used to provide power to sensors or other devices without the need to add a separate power supply module. Terminals to connect both a 16 to 18V AC 50-60 Hz plug pack and 12V DC 7.2AH sealed lead acid battery.
The module performs a battery test automatically every four hours as well as whenever an area is armed All On or Part On. The universal expander reports the backup battery condition as follows:

Normal = 12.5V or above
Low Battery = 11.5V
Battery Missing = 10.2V

LAN Wiring

On installations with a large number of LAN powered devices (Keypads, Zone and Output Expanders etc) it may be necessary to provide additional power. To insure that the LAN+ voltage remains at an acceptable level, the CM705B universal expander can be added to the system to regenerate the LAN+ voltage as well as power additional sensors or other devices. If the CM705B is one of the two furthest modules from the control panel then you should install the LAN termination shunt.

The diagram below shows the correct method for wiring the CM705B when LAN+ re- generation is required.

CM707B Plug On Zone Expander

The optional CM707B plug on module can be added via the expansion port on the CM705B universal expander to provide an additional 8 hard wired zone inputs bringing the CM705B universal expander to 16 hard wired zone inputs for Alarm

• Tamper, 4 state monitoring or Single EOL configurations.

The module is supplied with both 3K3 and 6K8 EOL resistors and three plastic PCB standoffs to mount the mod-ule onto the CM705B universal expander. You should fit the standoffs to the expander first and then connect the CM707B module.

Installing The CM707B Module

1. Ensure that the CM705B universal expander and the control panel is powered down before proceeding.
2. Plug the 3 short plastic standoffs into the CM707B plug on module.
3. Install the CM707B plug on module onto the EXPANSION PORT of the CM705B universal expander, making sure that the plastic standoffs are also inserted into the holes provided on the CM705B universal expander.
4. Re apply power to both the CM705B universal expander and control panel.
