Under ultra high or low temperature, where
the temperature can go above or below the
operating range of the smoke detector.
Operating temperature of the smoke detector
is
-10
o
C
～
50
o
C.
In very dusty or dirty areas. Tiny dust and
dirt can go through the filter and build up in
the chamber to make the smoke detector
over-sensitive or block openings to the
sensing chamber and keep the smoke
detector from sensing smoke.
Near fresh air inlets or returns or excessively
draughty areas. Airflow from air-conditioners,
heater, fans or air inlets will blow smoke away
from the smoke detector, making the smoke
detector less effective.
In dead air spaces at the top of a peaked roof
or in the corners between ceilings and walls.
Dead air may prevent smoke from reaching a
smoke detector.
Near fluorescent light fixtures. Electrical
“noise” from nearby fluorescent light fixtures
may cause a false alarm.
Install smoke
detectors at least 1.5m away from such
light fixtures.
Note: Never take the batter out of a smoke
detector to silence a nuisance alarm. Open a
window or fan the air around the smoke
detector to remove the smoke. The sound
will automatically turn off when the smoke in
the air is completely gone.
Do not stand close to the smoke detector.
The sound produced by the smoke detector
is loud and may be harmful to your hearing.
3.3 Mounting Method
Note: For new building, do not install the
smoke detector until fit up and cleaned up.
1)
Checking
Before installation, verify that the enclosure and
labels complete.
2)
Mounting
Warning: Installation of the smoke detector
must comply with local standards. Failure
may result in damage to life and property.
Fix the base of a smoke detector on the
ceiling by two
φ6 expansion bolts.
Align the small mark on the side of the
smoke detector with the arrow of
“
start
”
mark on the base and rotate the smoke
detector clockwise
.

Testing
The smoke detector has a buzzer, a button and a
red LED. Install the battery, press and held the
test button (as in Fig. 3), the buzzer will generate
alarming sound and the LED flashes quickly. C+
and C- of a smoke detector is closed. Release
the button, the smoke detector resumes to
normal operation. C+ and C- of a smoke detector
is opened.
Note: Remove dust cover for the first testing.
Put it on before the smoke detector operates
normally to protect again dust.

4. Usage and Function
4.1. Usage of the Smoke detector
This smoke detector is designed to sense smoke
entering into the smoke chamber. It does not
sense gas, heat or flame.
This smoke detector can monitor the air and,
when it senses smoke, activates its built-in alarm
buzzer to provide precious time for you and your
family to escape from your residence before a
fire spreads. Such an early warning, however,
is possible only if the smoke detector is located,
installed, and maintained as specified in this
manual.
Note: If the smoke detector is not used in a
network, it can only be used within single
residential living units, that is, it should be
used inside a single-family home or one
apartment of a multi-family building. In a
multi-family building, the smoke detector
may not provide early warning for residents if
it is placed outside of the residential units,
such as on outside porches, in corridors,
lobbies, basements, each residential unit
should have smoke detectors to alert the
residents of the unit.
