BATTERY REPLACEMENT
Make it a rule to replace the detector’s battery once a year even if there is
no indication that the battery is weak. Also be sure to replace it
immediately upon reception of a low battery message via your control
panel.
The battery must be replaced only by Size 2/3 CR 17345V
Lithium battery 3V Models: DL123A DURACELL Inc
When the battery is low the detector will send warning signal to the
control panel.
If the battery will not be replaced within a few days the beeper begins to
beep.
Install a new battery immediately. Keep fresh batteries on hand for this
purpose.
A. Remove the detector body from the mounting base,
B. Open the battery cover and remove the old battery,
C. Install a new battery according to polarity and close the cover.
D. Test the unit by pressing on the test button
E. Re-mount the detector on the mounting base
Caution: without batteries the unit cannot be mounted onto the
bracket properly!
Do not disconnect the battery from the detector. This will remove your
protection from fire.
If the alarm horn begins to beep once a minute, this signal means that
the detector’s battery is weak. Install a new battery immediately. Keep
fresh batteries on hand for this purpose.
1. Press the button and hold it till the smoke detector gives out an
intermittent alarm. After 8 seconds, the alarm will convert to the
rash sound like "Bi---Bi---Bi". It shows that it is in the normal
condition.
2. If the test fails, stop using the detector immediately.
3. Don’t test it with fire.
4. If the alarm makes low frequency sound several times, the
battery is low.
TEST PROCEDURE
The detector should be tested weekly and also whenever you
suspect that it does not go into alarm Walk Test
A. Set the control panel to "Walk Test Mode" as described in the Installer
Manual.
B. Push the test button (fig 1d) with your finger until the beeper sounds
C. Verify that the control panel responds to the transmitted smoke alarm.
If the detector fails, have it repaired or replaced immediately, to
ensure that it works properly.
WARNING:
Never use an open flame of any kind to test your detector. You may set
fire to damage the detector as well as your home. The built-in test switch
accurately tests all detector functions, as required by Underwriters’
Laboratories. This is the only correct way to test the unit.
NOTE:
If the alarm horn produces a loud continuous sound when you are not
testing the unit, this means the detector has sensed smoke or
combustion particles in the air. Verify that the alarm is a result of a
possible serious situation, which requires your immediate attention.
The alarm could be caused by a nuisance situation. Cooking smoke or a
dusty furnace, sometimes called "friendly fires" can cause the alarm to
sound. If this happens, open a window or fan the air away to remove the
smoke or dust. The alarm will turn off as soon as the air is completely
LIMITATIONS OF SMOKE ALARMS
1. United States NFPA72 tells that the safety of life is to be
noticed by alarms before fire, to confirm the correct escape
way. The fire systems help half of residents escape and we
should help the old people, women and children more because
they are always the victims.
2. Smoke alarms are not foolproof, they can’t prevent or
extinguish fires, and they are not a substitute for property or life
insurance. You need buy some firefighting facilities.
3. Sometimes the smoke is blocked by objects and can’t reach the
detector, and if the wind blows the smoke away from the
detector, the unit won’t work either.

IMPORTANT:
Never try to avoid false alarms by disabling the detector.
Do not mount smoke detectors in the path of fresh air intake. The flow
of fresh air in and out can drive smoke away from the smoke detector;
thus reducing its efficiency.
In damp or very humid areas or near bathrooms with showers.
Moisture in humid air can enter the sensing chamber, then turns into
droplets upon cooling, which can cause nuisance alarms. Install
smoke detectors at least 3 m (10 feet) away from bathrooms.
In very cold or very hot areas, including unheated buildings or outdoor
rooms. If the temperature goes above or below the operating range of
smoke detector, it will not work properly. The temperature range for
your smoke detector is 4C to 38C (40F to 100F).
In very dusty or dirty areas, dirt and dust can build up on the detector’s
sensing chamber, to make it overly sensitive. Additionally, dust or dirt
can block openings to the sensing chamber and keep the detector
from sensing smoke.
Near fresh air vents or very drafty areas like air conditioners, heaters
or fans.
Fresh air vents and drafts can drive smoke away from
smoke detectors.
Dead air spaces are often at the top of a peaked roof, or in the corners
between ceilings and walls. Dead air may prevent smoke from
reaching a detector.
In insect-infested areas. If insects enter a detector’s sensing
chamber,
they may cause a nuisance alarm. Where bugs are a problem, get rid
of them before putting up a detector.
Near fluorescent lights, electrical "noise" from fluorescent lights may
cause nuisance alarms. Install smoke detectors at least 1.5 m (5 feet)
from such lights.
WARNING:
Never remove batteries to stop a nuisance alarm. Open a window or fan
the air around the detector to get rid of the smoke. The alarm will turn
itself off when the smoke is gone. If nuisance alarms persist, attempt to
clean the detector as described in this manual.
WARNING:
Do not stand close to the detector when the alarm is sounding. The
alarm is loud in order to wake you in an emergency. Too much exposure
to the horn at close range may be harmful to your hearing.
REGULAR MAINTENANCE
Never use water, cleaners or solvents to clean your smoke
alarm since they may damage the unit.
Cleaning
1. Open the cover and vacuum the dust off the detector’s
sensing chamber at least once a year. This can be done
when you open the detector to change the battery. Remove
the battery before cleaning. Use the soft brush attachment
to your vacuum cleaner. Carefully remove any dust on
detector components, especially on the openings of the
sensing chamber. Replace the battery after cleaning. Test
the detector to make sure that the battery is in correctly.
Also make sure there is no foreign matter inside the test
button.
2. NOTE: If nuisance alarms keep occurring, check whether
the detector’s location is adequate (see p.4.1 and 4.2).
Relocate the unit if it is not located properly. Clean as
described above.
3. To clean the detector’s cover, first open the cover and
remove the battery. Hand-wash the cover with cloth
dampened with clean water. Dry it with lint-free cloth. Do not
get any water on the detector components. Replace the
battery, and close the cover. Test detector to make sure that
battery works correctly.
WARNING:
Dust can damage the smoke detector's sensitivity. The detector needs to
be cleaned at least once a year, use vacuum cleaner to clean dust out of
unit.
