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.
