Photoelectric smoke detector
Overview
My company succeed in developing a new generation of fire detectors, this detector using Infrared Radition scattering theory design, advanced SMT placement of the manufacturing process, perfect shielding measures, electromagnetic environment bad place to have the very good anti-interference ability. Also used the damp, anticorrosion, mildew prevent and other measures, in the high damp coastal areas have very good protection ability.
Performance and Characteristics
R Built-in infrared with high quality, containing sunlight filters, effectively filter environment light interference.
R Special optical labyrinth structure, fast response, good consistency.
R Advanced SMT paster technology,reliable shielding measures, the electromagnetic environment of bad places have very strong anti-interference ability.
R During normal working 5 seconds a bright lights and when fire the alarm indicator shows red.
R According to the new standard (The GB4715-2005 point type sense smoke fire detector)design.
