300 Series Photoelectric Smoke / Thermal Detector

Product Overview

2351TEM Photoelectric smoke / thermal detectors incorporate an optical chamber and a thermal element, which in turn are continually monitored by an on board processor by using algorithms developed specifically for the unit. An alarm signal is only enabled in the detector once the processor is satisfied that an incipient fire has been detected. By using a combination of inputs, the incidence of nuisance alarms is reduced while at the same time, the response time to an actual fire is also improved.
