Wireless Fire Alarm Smoke Detector
Installation
Instructions
1.Product Introduction
This wireless photoelectric fire alarm smoke detector adopts
unique structure design and MCU processing to photoelectric
signal in order to increase the functions of anti dust, insects
and white light interference to guarantee the stability. At the
same time, this detector is with wireless net linkage function
and suitable for different environments installation, which
has greatly increased users' sense for smoke alarm signal.
It is with better response to visible smoke caused by smoldering
and burning so it is suitable for fire alarm protection in
residential area, supermarket, factory, office, school, bank,
library, hotels, warehouse etc. Its functions and stability is
much better than those smoke detectors with similar prices
in the market
-Elegant appearance design
-Stable, safe and reliable
-Adopts super low power consumption processor and
software calculation
-Unique self-check function
-Lower power check and remind
-Anti RFI/EMI interference
-Adopts advanced SMT technology
-Detection range reaches 40
㎡
when installed at 2.3-6m;
60

4.Installation Guide And Operation Principle
1.When installation height is less than 6m, and
detector is installed on diaphragm, the distance
from lower surface of detector to ceiling can't
be over 0.3m
2.Distance from detector to ventilation hole must
be more than 1.5m when there is air-conditioner
in the room
3.Detector must be installed at 0.6m over the wall
or girder.
Detector's protection range and calculation on how
many detectors should be installed in a space
Can get detection range of 40m² when
installed at the height of 2.3-6m

Installation
slip hook
Press down TEST button for 0.5 second, buzzer will
send out one “Di” sound and then send out wireless
smoke alarm signal
Keep pressing down the TEST button, buzzer will
send out three “Di, Di, Di” sounds and repeat this
each 1.5 seconds, then red alarm LED keeps on, that
means detector is working well, detector will return
to normal working status after release of TEST button
Optical maze
Fit for installation in:
Residential area, cafe, KTV, hotel, restaurant,
apartment, trattoria etc.
Not suitable for:
place full of dust, powder and plenty vapour;
place that might be with corrosive gas;
kitchen and other place that might with smoke remain;
place with oversized temperature and humidity;
place with ventilation speed over 15m/sec
Detector's detection to smoke can be fulfilled by
optical maze, there are a pair of infrared transmitter
and receiver, their ejection angle is around 120°,
when there is no smoke, receiver can't receive the
infrared light from transmitter, so there will be no
voltage output from following circuit. When there
is smoke, smoke enters the maze and scatters the
infrared light from transmitter. Receiver receives
the scattered infrared light and makes voltage output
at the following circuit, the thicker the smoke is,
the stronger scattering is, and the higher voltage is.
When the voltage reaches preset value, detector
sends out alarm signal and alarm is triggered.
