Standard Temperature Detector, XPERT style, 55000-400IMCÂ High Temperature Detector, XPERT style, 55000-401IMC Context Plus XP95 temperature (heat) detectors have a common profile with ionisation and optical smoke detectors but have a low air flow resistance case made of self-extinguishing white polycarbonate. They monitor temperature by using a single thermistor network which provides a voltage output proportional to the external air temperature.
The response to temperature increases of the standard temperature detect tor (part no: 55000-400IMC) enables the detector to be utilised as an EN54 Grade 2 heat detector.
To provide a device for use in ambient temperatures of up to 55°C, a high temperature detector (part no: 55000-401IMC) is also available. This has similar characteristics to the standard temperature detector at 25°C but reaches a 55 count (alarm) at 90°C.
