产品介绍：
该产品名为光电式烟雾探测器，通过几个红外二极管探测烟雾
检测的原理是烟雾中的颗粒可以反射红外光
红外二极管放置在特殊腔室中
该室可以屏蔽外部光，但不影响进入它的烟
虽然没有烟，但二极管可以接收非常弱的红外光
当烟雾进入室内时，二极管可以接收到越来越多的光，并且当烟雾所有密度达到一定密度时，检测器可以发出报警信号
为了减少干扰和降低功耗，发射电路采用脉冲信号
该产品按照联网方式分为2线和4线检测器

Product introduction:
This product named Photoelectric smoke 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 allains 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

Product featurs:
*Strong adaptability for circumstance
*SMT design, high stability
*9-35V DC wide voltage operating range
*Low standby current
*Power supply non-polarized input
*Twin LED for 360 visual
*Flashing LED power indicator
*Remote LED indicator output (2-wire)
*Metal shield, anti-eletromagnetic
*Interference
