Photoelectric Smoke Detector

Conventional Photoelectric Smoke Detector ($\Phi 105\text{mm}$)

The Conventional Photoelectric Smoke Detector is engineered to provide early warning of developing fires by detecting visible smoke particles. Utilizing a high-precision photoelectric sensing chamber, this detector is exceptionally responsive to slow-smoldering fires commonly caused by wiring, furniture, and synthetic materials.

Featuring an innovative dust- and insect-resistant design along with non-polarized multi-wire compatibility, it offers stable, long-term monitoring with minimal maintenance for residential, commercial, and industrial property safety profiles.

Key Features & Performance Advantages

• Advanced Photoelectric Chamber: Highly sensitive optical sensor optimized for cotton wicks smoldering tests ($m=0.15\%\text{dBm}$) to intercept fire risks before they break out into open flames.

• Expansive Coverage Footprint: Efficiently monitors a protection zone of up to 60m2 when mounted at standard ceiling heights up to 4 meters.

  PDF

• Universal Wiring Architecture: Equipped with a non-polarized terminal system supporting 2-wire, 3-wire, or 4-wire configuration models for seamless integration into any conventional fire panel system.

  PDF

• Ultra-Low Monitoring Power Draw: Consumes a minimal standby static current of $\le 50\mu \text{A}$ ($12\text{–}35\text{V}$), preserving emergency backup battery life across standard fire loops.

  PDF

• Smart Power-Up Reset: Features an automated system reset or an optional 0.5-second power-off loop reset to immediately normalize the sensor after routine maintenance testing.
