Description

Photoelectric Smoke Detector
Features

Ultra low power consumption with non-polarized two wire bus.
Professional microchip provides highest reliability.
Combined infrared ray with blue ray detection technology allows a higher level of false alarm immunity.
Drift compensation for environmental changes and device aging, reduces sensitivity changes and extends the lifespan.
Patented labyrinth design, smoke enters from the top of the detector to remove azimuth error.
A completely new chamber design is proven in extensive testing to be more efficient, less liable to false alarm due to strong light, strong interference and dust and achieve no-clean basically.
The indicator LED is on the top of the detector that provide 360 ° local visual indication of the device status.
Each detector has a unique detector ID at the back.
Electrically addressed, can be modified online or by a programmer.
Rotary designed to ease installation.
