Fire Trigger/Relay

The PDB-1R uses an end-of-line resistor to trigger a form "C" contact in response to a fire system alarm condition. In response to the trigger, the unit transfers power from the "Normally On" output to the "Normally Off" output. Additional triggered reactions include status feedback to fire control or annunciation systems, ground fault trigger and input trigger that latches until reset.

Product Features
