UL Listed Intelligent Combination Heat Photoelectric Smoke Detector DI-M9101

UL Intelligent Combination Heat Photoelectric Smoke Detector

DI-M9101 integrates photoelectric detection and fixed temperature detection technology by combining smoke sensor and semi-conductor heat sensor in mechanism and circuitry structure. Just because of the combination of smoke detection and heat detection, it not only overcomes the disadvantage that detectors using common infrared scattering technology are insensitive to black smoke with small particles, but also can pick up fire with obvious rise of temperature such as alcohol flame, thus extending its application range.
