CM705B - Universal Expander Module
The CM705B universal expander provides a cost effective way to increase the control panels zone inputs, program-
mable 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.
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 as-
signed 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 dis-
able 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 mod-
ules 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.
