The 850H is an addressable heat only fire detector with the majority of the MX VIRTUAL detectors features.
The 850H is a flexible cost-effective addressable heat detector with most of the features of MX VIRTUAL detectors. The 850H reports the temperature to the MX fire alarm panel which allows various detection modes.
The 850H uses a high quality thermistor with very low thermal mass. This allows the detector to function as a heat detector as well as providing a fast and accurate temperature display.
