Potter PAD200-PHD Photoelectric Smoke/Heat Detector Combination

The Potter PAD200-PHD combination multi-sensor offers intelligent fire protection for spaces requiring highly reliable smoke and thermal monitoring, such as modern multi-family complexes, educational facilities, and commercial office networks. By running simultaneous analysis on both its internal optical chamber and integrated thermal circuit, the device evaluates real-time environment metrics to verify smoke particles and rapid temperature changes before alarming. This dual-criteria processing ensures faster detection of volatile synthetic fires while dropping nuisance alarms from typical indoor triggers like steam and dust. It transfers data continuously over standard 2-wire Signaling Line Circuits (SLC) using the analog PAD protocol. Hardware addresses are assigned locally via rugged 7-position DIP switches mounted directly to the plastic frame, bypassing the need for electronic programming accessories. The detector head fits with a twist-lock motion into any PAD100 series mounting layout, featuring clear status LEDs for easy visual validation from floor level.
