6.4 Fire Alarm Control Panel Connection

• The CM 12's controller is equipped with a normally open input signal, which can be connected

directly from the fire alarm control panel. When receiving the signal from the fire alarm control
panel, the unit turns off and does not turn back on until power source is reset or turns the wall
thermostat off and on.

1) Connect the fire alarm signal wires to CM 12 signal wires label E+ and E-.
2) Use recommended fire alarm signal wire size from 16 AWG to 26 AWG for a solid wire, or 16

AWG to 22 AWG for a stranded wire.
