ESSER 802372 Isolator Rate-of-Rise Heat Detector

Esser 802372 is an isolator-equipped heat detector that senses the rate of temperature rise. With its single thermistor design, it continuously measures ambient air temperature; its fast semiconductor sensor provides reliable response in fires with rapidly rising temperatures. The rate-of-rise principle operates independently of the environment's normal temperature level, thus maintaining equal sensitivity in cool and warm spaces.
