I-9101 Intelligent Combination Heat/Photoelectric Smoke Detector is consisted of smoke sensing and semi-conductor temperature sensing parts in processing and circuitry. This non-addressable detector has the advantages of both conventional photoelectric detector and rate of rise and fixed temperature heat detector. Just because of the combination technology of smoke detector and heat detector, it overcomes the non-sensitivity to dark smoke particles of ordinary scattering type photoelectric detectors. It can also pick up fire with obvious rise of temperature such as alcohol fire, thus extending the application range.
