The multi-criteria multi-sensor 22051TE Photo Thermal detector uses thermal assistance to the core photoelectric smoke detector to give enhanced false alarm immunity and faster response to a wide range of incipient fires.
The plug-in unit combines two separate sensing elements that are managed by embedded software to act as a single unit. The 22051TE conforms to EN54-5, a 58°C fixed temperature and rate of rise thermal, with the smoke detection element conforming to EN54-7.
