Honeywell 802374 O2T Multi-Sensor Fire Detector with IQ8Quad Isolator
Addressable IQ8Quad series multi-sensor fire detector; combines a patented dual-angle optical scatter sensor with an additional heat sensor, includes an integrated short-circuit isolator, and operates on the esserbus/esserbus-PLus loop; suitable for critical areas such as hotels, casinos, kitchens, lobbies, and similar locations, and must be mounted with a separate base (805590, 805591 or 767800).
Dual Sensor Detection
Provides a combination of a patented dual-angle optical scatter sensor (O2) and a heat sensor (T).
Smoke Classification
Reduces false alarms by distinguishing misleading phenomena such as water vapor or dust through smoke classification.
Integrated Isolator
An integrated short-circuit isolator is located within the detector.
Application Area and Mounting
Monitored area 110 m2, requires a separate detector base (805590, 805591 or 767800).
