Battery Powered Photoelectric
Smoke Alarm User Manual
1 2
This product is a battery operated photoelectric smoke alarm,
adopting unique structure design and advanced photoelectric
sensor technology, able to monitor and detect smoke particles in
real time. Especially detects visible particles (associated with
smouldering fire) sooner than ionization alarms. Once smoke
particles or a fire danger is detected, this alarm will chirp and the
red LED will flash rapidly to alert you and your family timely.
Furthermore, this alarm has dustproof, mothproof and anti-light
interference etc. functions, ensuring stability from design basis
and suitable for early warning and protection of fires in houses,
factories, shopping malls, hotels, office buildings, school
buildings, banks, libraries and warehouses etc. indoor places.

INSTALLATION
1.Avoid installations in places with stagnating smoke, heavy
dust, heavy water mist, heavy oil mist, great humidity (>95%)
and high wind speed (>5m/s).
2. Insert the battery correctly into the battery compartment
according to the marked positive and negative polarity.
3. Choose a proper position. Normally the center of the detection
area ceiling is recommended. If impractical, do not install the
detector in area without air flow (as Figure 1). For roof with
oblique beam, the ceiling is also oblique where the detector
should be installed at a position with 0.9m horizontal distance
to spire (as Figure 2). Fix the detector base into a chosen
position with screws. Then put the detector head into the
base and twist clockwise to fasten it (as Figure 3). At last,
plug in the tamper resist locking pin (as Figure 4).

1. Battery is equipped on delivery. Unpack the battery insulation
cement to active the battery before using.
2. After activating the battery, the smoke alarm enters into
normal monitoring status. The LED blinks once every 40s.
3. Sensitivity Test
To ensure normal operation, periodic tests should be
performed. Once a month is recommended. For testing, press
and hold the Test Button more than 3s to enter into sensitivity
test status. The alarm indicator will flash rapidly and buzzer
will give out alarm sound, which indicates the smoke alarm
works properly. During testing, keep ears away from the
smoke alarm to avoid hearing damage.
