Conventional S300 – Thermal Detectors

Series 300 thermal detectors (5351TE, 5351EA & 4351EA) push the boundaries of existing conventional detector technology. They are detectors which ‘act conventionally, think intelligently’.

The three thermal detectors, a 58°C (5351TE), a 78°C (4351EA) fixed temperature units and a rate of rise unit (5351EA), use state of the art thermal elements combined with application specific integrated circuits (ASIC) to provide quick and accurate detection of fires through temperate levels or changes.

The detector also has an integrated LED which illuminates to provide a local alarm signal. This remains illuminated until the detector is reset by a momentary power disruption. An optional LED annunciator may be used to repeat any alarm signal.
