4-wire smoke detector smoke sensor fire alarm with NO/NC DC9-35V

 4-wire smoke detector smoke sensor fire alarm with NO/NC DC9-35V

PRODUCT INTRODUCTION

This product named Photoelectric smoke

detector(hereinafter called detector) detects the smoke by a

couple of infrared diodes. The principle of detecting is

granule in the smoke can reflect infrared light. Infrared

diodes are placed in the special chamber. The chamber can

shield external light, but doesn't affect the smoke into it.

While there is no smoke, the diode can receive very weak

infrared light. When the smoke entering the chamber,diode

can receive more and more light,and the detector can give

out alarm signal when the smoke attains the certain density.

In order to reduce the interference and lower power

consumption, the emitting circuit adopts the pulse signal.

The product in accordance with the networking approach is

divided into 2- wire and 4-wire detectors.
