The detector incorporates a static element and is suitable where ambient conditions normally exhibit rapid changes in temperature above 45ºC e.g. boiler houses.
Honeywell 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.
The Conventional Notifier FD-851HTE A 78°C Fixed temperature Heat detector, consists of a thermistor detecting high temperatures.
The Conventional Notifier FD-851HTE A 78°C Fixed temperature Heat detector, consists of a thermistor detecting high temperatures. Suitable for use in environments having high base temperature (above 35°C) with alarm temperature set at 78°C. Ready for testing by remote control laser. Alarm LED. Output for alarm repeater. Possibility for addressing through additional module.
