AC120 240V Photoelectronic Smoke detector 4 wired NO NC Smoke Sensor Fire Alarm

PRODUCT INTRODUCTION

  this product named Photoelectric 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,b-

Ut don't affect the smoke into in.while have no smoke,the diode can receive very weak infrared light. When the sm-oke entering the smoke attains the certain density, the de-  tector can give out alarm signal. In order to reduce the in- terference and lower power consumption, the emitting ci- rcuit adopts the pulse signal. the detector adopts the spe- cial structure design and ASIC, has the dustproof, mothp- roof and anti outside light interference feature and etc.the detector is suitable for detecting the smoke in ho-use, shop,hotel, restaurant, office building, school, band,bank, libr- ary,computer house,storehouses and etc.
