The Context Plus Standard Temperature Heat Detectors have a common profile with optical smoke detector 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 detector enables the detector to be utilised as an EN54 Grade 2 heat detector.
