防火灾烟雾感应探测器光电式烟雾报警器外贸出口型AK-218B

产品概述:
本产品为光电式感烟探测器（以下简称探测器）是采用烟雾中的颗粒折射红外光的原理探测火灾，电路主要由红外发射部分和接收部分组成，发射管与接收管置于光学迷宫中，光学迷宫可屏蔽外界杂散光的干扰，但不影响烟雾进入。在无烟状态下，接收管只接收到很弱的红外光，当有烟雾进入时，由于散射作用，接收到的光信号增强，当烟雾达到一定浓度时，控测器输出报警信号。为减少干扰及降低功耗，发射电路采用脉冲方式工作，可提高发射管使用寿命。产品具有防尘，防虫，抗外界光线干扰等功能，保证了产品的稳定性。本产品对缓慢阴燃或明燃产生的可见烟雾，有较好的反应。适用于住宅、商场、宾馆、饭店、办公楼、教学楼、银行以及仓库等室内环境的烟雾监测。

简易保养：
**每隔6个月便需清洁警报器一次以保持工作效率良好，先把电源关掉，再用软毛刷轻扫灰尘便可。再把电源启动。
若发现以下问题：
1、 按了测试健但不发声

2、烟雾测试但不发声
3、 预备灯不再稳定闪动

避免安装於以下位置：
1． 太接近门口，窗户，风扇等地方均会影响警报器的灵敏。因为这些地方一般空气流通较快。
2、 不可安装於高潮温度的地点，如浴室，顶楼或温度高於39ºc或低於5ºc。

注意事项：
1、本产品不宜安装在极冷极热、风速极高以及经常会有大量烟雾和灰尘存在的环境中。
2、产品每月进行一次测试。
3 为保证产品的感烟灵敏度，每隔六个月需要用软毛刷清洁探测器表面，清洁时必须先断开电源。
4、（独立型或无线型）当电池电压不足时，峰鸣器会每隔40秒发出短促的“嘀”声，为保证探测器的探测灵敏度，请及时更换电池。
5、如果发现产品不能正常工作，或者有损坏现象，请不要自行拆卸，可以联系客户服务中心或者Zui近的代理机构，将有专业人员为您服务。
6、光电感烟探测器可以减少灾难的发生，但不能确保万无一失。为了您的安全，请正确使用本产品，同时在日常生活中应提高警惕，加强安全防患意识。

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, but don't affect the smoke into it. while have no smoke, the diode can receive very weak infrared light. when the smoke entering the chamber, diode can receive more and more light, when the smoke attains the certain density, the detector can give out alarm signal. in order to reduce the interference and lower power consumption, the emitting circuit adopts the pulse signal. the detector adopts the special structure design and asic, has the dustproof, mothproof and anti outside light interference feature and etc. the detector is suitable for detecting the smoke in house, shop, hotel, restaurant, office building, school, bank, library, computer house, storehouse and etc.
