Note:
1. The alarm relay contacts are rated for a maximum of 24VDC and 800mA, when connecting to an external
power source.
2. The CMC can supply up to 160mA to users from its internal 24VDC power supply via the two alarm relay
ports. The 160mA can be split as needed between the two ports.
3. Intrusion sensors can be connected to Auxiliary 1 and 2 input ports to allow monitoring additional doors.
Users may also wire a simple switch closure device between pins 1 and 2. Pin 2 is connected to the CMC
signal ground and pin 1 is connected to the CMC signal input. Opening or closing the switch will trigger an
alarm, as configured in the software setup.
