Discovery Heat Detector [SIL2]

58000-400SIL

The Discovery Heat Detector features a low airflow resistance case and a single thermistor to sense the air temperature around the detector.

Reliable fire detection in areas with a very wide temperature range from -40°C to +70°C
Five operating modes suitable for a range of application temperatures
Ideal for environments that are dirty or smoky under normal circumstances
Drift compensation to ensure constant sensitivity
Remote test feature
Assessed and certified for use in a safety function to SIL level 2
