Documents, Certifications & Listings

Distributed Power Control Interface for Fire, Access, HVAC, Elevator, and Security.

The PDB-8C1R /8F1R power distribution control interface converts a main non-power limited DC power source to 8 power-limited outputs that can be controlled by a Fire Alarm Control Panel.  Each output can be selectively set to turn ON or to Turn OFF when triggered by the panel.  The system can interface to the PDB-8C1R /8F1R with either of two or both supervised trigger inputs.
