Description
**Fire Relay Initiates Power Transfer During Alarm Events**
The PDB-1R integrates an end-of-line resistor to activate a form “C” contact when a fire alarm system is triggered. Upon activation, the device transfers power from the “Normally On” output to the “Normally Off” output. Additional activated responses include status feedback to fire control or annunciation systems, ground fault activation, and an input trigger that remains latched until manually reset.
