The photoelectric smoke detector is designed to sense smoke
that comes into the detector chamber. It does not sense gas,
heat, or flame. This smoke detector is designed to give early
warning of developing fires by giving off the alarm sounds from
its built-in alarm horn. It can provide precious time for you and
your family to escape before a fire spreads.

WHERE NOT TO INSTALL SMOKE ALARMS
Nuisance alarms take place when smoke detectors are installed where they will not work properly. To avoid
nuisance alarms, do not install smoke detectors in the following situations:
> Combustion particles are the by-products of something that is burning. Thus, in or near areas where
combustion particles are present you do not install the smoke detectors to avoid nuisance alarms, such as
kitchens with few windows or poor ventilation, garages where there may be vehicle exhaust, near furnaces,
hot water heaters, and space heaters.
> Do not install smoke detectors less than 20 feet (6 meters) away from places where combustion particles
are normally present, like kitchens. If a 20-foot distance is not possible, e.g. in a mobile home, try to install
the detector as far away from the combustion particles as possible. To prevent nuisance alarm alarms,
provide good ventilation in such places.
> 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 10 feet (3 meters) 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 40 °F to 100 °F (4 °C to 38 °C).
> 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.
>Install a smoke detector inside every bedroom.
>Install smoke detectors at both ends of a bedroom hallway if the hallway is more than 40 feet (12 meters)
long.
>Install a smoke detector inside every room where one sleeps with the door partly or completely closed,
since smoke could be blocked by the closed door and a hallway alarm may not wake up the sleeper if the
door is closed.
>Install basement detectors at the bottom of the basement stairwell.
>Install second-floor detectors at the top of the first-to-second floor stairwell.
>Install additional detectors in your living room, dining room, family room, attic, utility and storage rooms.
>Install smoke detectors as close to the center of the ceiling as possible. If this is not practical, put the
detector on the ceiling, no closer than 20 inches (50 cm) from any wall or corner, as shown in Figure 3.
>If some of your rooms have sloped, peaked, or gabled ceilings, try to mount detectors 3 feet (0.9 meter)
measured horizontally from the highest point of the ceiling as shown in Figure 4.

3. Remove the bottom cover.
4. Using an electric drill with a 6.5mm drill bit, bore two holes on the
pencil mark, put the unit away from getting plaster dust on it when you
drill holes for mounting.
5. Tap the plastic dilatants into the holes with hammer and then strike
the 3*30 screws into the dilatants; and tighten the screws to fix the
bottom cover.
6. Insert 9v cascading battery into battery box, if you don’t do that, you
cannot fix the alarm body on the bottom cover.
7. Make the hole on the middle cover aligned with the lock button on
the bottom cover and turn the alarm body clockwise.
NOTE: When the detector battery first makes contact with the
detector, the alarm horn may sound for one second. This means
normal and indicates that the battery is positioned properly.
Close cover, then press the test button, holding it down for about
5 seconds until the horn sounds. The horn should sound a loud,
pulsating alarm. This means the unit is working properly.
INSTALLING YOUR SMOKE DETECTOR
The smoke detectors are to be mounted on the ceiling. Please follow these steps to install your smoke
detector:
1. Hold the bottom cover firmly and then turn the body anti-clockwise to release the bottom cover down.
2. Hold the bottom cover on the selected installing position, make hole mark with pencil at the center of the
installing slot/hole on the bottom cover.
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 User’s 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.
> 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 5 feet (1.5 meters) from such lights.
RED INDICATOR
The red LED, as the ALARM indicator, is featured with the detector. It can be seen through the test button
on the cover of the detector. When red LED flashes once 35 seconds, it indicates the detector under normal
operation. When smoke detector senses smoke and simultaneously sounds an audible alarm, the red LED
will flash very frequently, once 0.5 seconds.
TESTING YOUR SMOKE DETECTOR
Test the detector weekly by pushing firmly on the test button with your finger until the horn sounds. Testing
method may take up to 20 seconds to sound the alarm horn. These are only ways to be sure that detector
is working correctly. If the detector fails to test properly, have it repaired or replaced immediately.

TAKING CARE OF YOUR SMOKE DETECTOR
To keep your detector in good working order, you must test the detector weekly, as referring to section
“TESTING YOUR SMOKE DETECTOR”.
> Replace the detector battery once a year or immediately when the low battery “beep” signal sounds once
a minute. The low battery “beep” should last at least 30 days.
NOTE: For replacement battery , use Eveready #522, #1222, #216; Duracell #MN1604; or Gold Peak
#1604P, #1604S; or Ultralife U9VL-J.
> 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 battery before cleaning. To clean
detector, use soft brush attachment to your vacuum. Carefully remove any dust on detector components,
especially on the openings of the sensing chamber. Replace battery after cleaning. Test detector to make
sure battery is incorrectly. Check to make sure there are no obstruction inside the test button. If there is
any dust in the test button, insert a toothpick from the back to the front.
> Clean detector cover when it gets dirty. First open the cover and remove battery. Hand-wash 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 cover. Test detector to make sure that battery works
correctly.
WARNING:When you are not testing the unit and the alarm horn sounds a loud continuous
sound, this means the detector has sensed smoke or combustion particles in the air.
Be sure that the alarm horn is a warning 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 to remove the smoke or dust. The alarm will turn off as soon as the air is completely
clear.
>If the alarm horn begins to beep once a minute, this signal means that the detector’s battery is
weak. Replace new battery immediately. Keep fresh batteries on hand for this purpose.
WARNING: Never use an open flame 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. They are the only correct ways to test the unit.
