Fire Relay Module

With the switch or fire panel contacts (FPC) CLOSED wire the load across 0V and NC or NO terminals (dependant on Fail Secure/Fail Open operation). With the LED OFF the contacts are in the position marked.

When the SWITCH or the FPC is operated, then the output from NC and NO will change state to either apply or remove the voltage.

The 0V and +VE terminals are not affected by the operation of the relay unit.

By using R+ and/or R- you can operate the respective relay contacts. This allows deactivation of door closers while still maintaining power to other equipment, cutting down on the need to route cables unnecessarily.
Ensure the total current drawn does not exceed the rated capacity of the power supply equipment.
