COM = Neg Relay Terminal

NC = Normally Closed Relay Terminal


IMPORTANT NOTE: The max permissible load on any of the relay terminals is 500mA or 0.5A. If you need to drive more current, an external relay/contactor, with coil loads under 500mA, needs to be used. The maximum voltage across any of the alarm terminals is 48V...
