F1000-886 | Discovery Multisensor Photo/Heat Detector

75163

This detector combines inputs from optical and heat sensors and processes them using a sophisticated algorithm.

When polled by the control panel it returns an analog count which is determined by combined responses from both optical and heat sensors. The multi-sensor detector is designed to be sensitive to a wide range of fires and may be used in place of an ionization detector in many instances.

The multi-sensor can be fitted in place of ionization detectors where these prove to be too sensitive and cause unwanted alarms.
