PAD300-PHD Photoelectric Smoke and Heat Detector

The Potter PAD300‑PHD is a reliable analog addressable fire alarm detector that combines photoelectric smoke detection with a heat sensor (rate-of-rise and/or fixed). It works over a PAD (Potter Addressable Device) loop and communicates its sensitivity directly to the control panel. The low-profile, off-white housing blends discreetly into ceilings, while built in drift compensation and a dirty detector warning help maintain dependable performance over time.
