photoelectric smoke detector 1.Test by hand 2.Auto-reset 3.ASIC adopted 4.SMT design

photoelectric smoke detector

 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.During normal working 5 seconds a bright lights and when fire the alarm indicator shows red.

According to the new standard ”The GB4715-2005 point type sense smoke fire detector“design.
