Fire-Lite AD365 Addressable Multi-Criteria PhotoelectricThe AD365 IV and AD365A IV are plug in addressable multi criteria detectors that replace the AD355 Series. They combine photoelectric, thermal, and infrared (PTIR) sensors in one unit to sense multiple components of a fire. This approach enables enhanced sensitivity to real fire with heightened immunity to nuisance particulates. Multiple sensors and communication can greatly reduce nuisance alarms compared to single sensing methods. Sophisticated
