Description
DI-9101E intelligent combination heat photoelectric smoke detector integrates photoelectric detection and fixed temperature and rate of rise detection technology by combining smoke sensor and semiconductor 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.
