AD365 Multi-Criteria Detector

AD365 multi-criteria detectors are plug-in addressable detectors that 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 can greatly reduce nuisance alarms compared to single sensing methods, and sophisticated algorithms maximize the advantages of the sensor types. Photoelectric sensors detect airborne particles associated with smoke.

Thermal sensors detect heat and rate-of-rise (135 °F fixed-temperature threshold), infrared sensors discern light patterns in the environment as an additional data-point for alarm determination. This ability to reject certain nuisance alarm triggers, such as theater smoke, supports the use of the detector in applications where moderate to heavy nuisance conditions exist that might cause single sensing detectors to trigger a false-alarm. The PTIR detector meets both UL 268 and UL 521 listing requirements and can indicate distinct smoke and heat alarms. This dual nature supports a local alarm setting for photoelectric detection and a general evacuation setting based on thermal detection.
