S200 Addressable Photoelectric Smoke/Thermal Detector

The Series 200 photo-thermal detector range delivers a consolidated, reliable, high-quality detector platform with digital communication, suitable for medium-to-large applications with simple installation requirements.

The 22051TE/TEI Photo Thermal detector uses thermal assistance to the core photoelectric smoke detector to give enhanced false alarm immunity and a 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. In areas where the normal daytime activities may potentially create unwanted alarms, the detector can be programmed to operate in a “heat only” mode, automatically reverting to full photo-thermal operation during unoccupied periods.
