1. General

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 in.While have no smoke,the diode can receive very weak infrared light. When the smoke entering 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, band,bank, library,computer house,storehouses and etc.

2. Feature

The detector works once connected to DC power directly. Operation Indicator flashing signifies detector working normally and Alarming Indicator on signifies detector alarming. Built-in a couple of output contact, contact connect/disconnect after alarm. Powerdown/Auto-reset when no smoke exiting nearby. Intalling with mounting base.

4．Installation

·         Connect the power line and signal line to the mounting base(1 for power contact, 2 for cathode, 3 and 4 for Alarm NO/NC Contact).

·         Open the small buckle on the bage board, then according to the instruction, use the jumper to choose the detector's reset mode and alarm output mode.

·         Select proper place (normally mounted on the center of the ceiling), fix the mounting base, then put the detector into the base and turn it.

5．Notice

·         The detector cannot be installed under worse environment. E.g. Coldest, hottest, dusty, do not move away the dustproof cover until use the detector indeed.

·         Make sure that there is no block within 0.5m from detector.

·         Keep the distance between detector and source of wind flow more than 1.5m.

·         Keep the distance between detector and wall more than 0.5m.

·         Make sure the distance between detectors is less than 15m. And the distance between detector and corner must be less than half of the one between detectors.

·         Horizontally install the detector. If have to be installed slantingly, please keep the angle less than 45degrees.

·         Please clean the detector by soft brush per six months to ensure the sensitivity and life of product. Pay attention to switch off power before clean.

·         For various reasons, including, but not limited to changes in environmental condition, electric disruptions and tampering, the product may not perform as expected. The user is advised to take all necessary precautions for his/her safety and the protection of his/her property.
