AHS-871 Photo Type Smoke Detector

Key Specifications/Special Features:

  • Newly developed SMT circuit - compact, with high stability and low power consumption
  • Several power-stabilizing ballasts installed independently
    • Stabilizes voltage fluctuation
    • Suitable for normal operation from 12V to 30V
  • Uses a cord-disconnection type for base mounting, so the control panel can send out a disconnection signal when the dectector is loosened
  • 0.8mm radius anti-insect mesh made of stainless steel prevents insects from entering and setting off a false alarm
  • Stainless steel also efficiently eliminates static
  • Smoke-conduction is designed to prevent strong light from influencing the system, while letting smoke enter easily
  • Steam will not stay on the mesh, thus avoiding false alarms
  • Operation principle:
    • Light will project in all directions when it comes into contact with smoke.
    • When the sensor catches the infrared light, it means the smoke has reached a fixed level.
    • The light-dispatch diode sends a light signal every three seconds to check the smoke.
    • When smoke reaches a fixed level, the light-receiving diode will confirm it three times and then send signal to the fire control panel.
