System Sensor 22051TEI-26 Multi-Sensor Detector with Isolator

The System Sensor 22051TEI-26 Multi-Sensor Detector with Isolator features thermal assistance to the core photoelectric smoke detector to provide enhanced false alarm immunity and faster response to a wide range of incipient fires.

The detector combines two separate sensing elements that are managed by embedded software to act as a single unit. Conforms to EN54-5, a 58 degrees fixed temperature and rate of rise thermal with the smoke detection element conforming to EN54-7.
