CAUTION (As required by the California State Fire Marshall) “Early
warning fire” detection is best achieved by the installation of fire
detection equipment in all rooms and areas of the household as
follows: (1) A smoke detector installed in each separate sleeping area
(in the vicinity, but outside of the bedrooms), and (2) Heat or smoke
detectors in the living rooms, dining rooms, bedrooms, kitchens,
hallways, attics, furnace rooms, closets, utility and, storage rooms,
basements and attached garages.”
For your information, NFPA Standard 72, Section 29 reads as follows:
“29.5.1 Smoke detectors shall be installed outside of each separate
sleeping area in the immediate vicinity of the bedrooms and on each
additional story of the family living unit including basements and
excluding crawl spaces and unfinished attics.
The provisions of 29.5.1 represent the minimum number of alarms
required by this standard. It is recommended that the householder
consider the use of additional smoke detectors for increased protection
for those areas separated by a door from the areas protected by the
required smoke alarms under 29.5.1 above. The recommended
additional areas are living room, dining room, bedroom(s), kitchen,
attic (finished or unfinished), furnace rooms, utility room, basement,
integral or attached garage, and hallways not included in 29.5.1 above.
However, the use of additional alarms remains the option of the
householder.” We recommend complete coverage and use of
additional smoke detectors.

LOCATIONS NOT TO INSTALL YOUR SMOKE DETECTORS

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

INTRODUCTION
GlobalSat’s single station photoelectric smoke detector LS-134H is
designed to sense smoke that comes into the alarm chamber. It does
not sense gas, 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. However, the smoke detector
makes such pre-warning of fire accident possible, only if the smoke
detector is located, installed, and maintained properly as described in
this User Manual.

WARNING: This smoke detector is designed for use in a single
residential unit only, which means that it should be used inside a
single family home or apartment. It is not meant to be used in lobbies,
hallways, basements, or another apartment in multi-family buildings,
unless there are already working alarms in each family unit. Smoke
detectors , placed in common areas outside of the individual living
unit, such as on porches or in hallways, may not provide early warning
to residents. In multi-family buildings, each family living unit should
set up its own smoke detectors.

WARNING: This detector is not meant to be used in non-residential
buildings. Warehouses, industrial or commercial buildings, and
special purpose non-residential buildings require special fire detection
and alarm systems. This smoke detector alone is not a suitable
substitute for complete fire detection systems for places where many

LOCATIONS TO INSTALL YOUR SMOKE DETECTOR

Smoke detectors should be installed in accordance with the NFPA
Standard 72 (National Fire Protection Association, Battery march
Park, Quincy, MA 02169). For complete coverage in residential units,
smoke detectors should be installed in all rooms, halls, storage areas,
basements, and attics in each family living unit. Minimum coverage is
one detector on each floor and one in each sleeping area.

Here, we have useful tips for you:
˙Install a smoke detector in the hallway outside every separate
bedroom area, as shown in Figure 1. Two alarms are required in
homes with two bedroom areas, as shown in Figure 2.
˙Install a smoke detector on every floor of a multi-floor home or
apartment, as shown in Figure 3.

˙Install a minimum of two detectors in any household.
˙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 detector may not wake up the sleeper if
the door is closed.

people live or work, such as hotels or motels. The same is true of
dormitories, hospitals, nursing homes or group homes of any kind,
even if they were once single family homes. Please refer NFPA 101,
the Life Safety Code, NFPA 72A for smoke alarm requirements for
fire protection in buildings not defined as “households”.

WARNING: This smoke detector will not alert people who are hard
of hearing. It is strongly recommended that the special-purpose smoke
detectors, using lights or vibrating devices, should be installed to alert
occupants who are hard of hearing.

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, preferably on the wall. To prevent nuisance alarm alarms,
provide good ventilation in such places.

IMPORTANT: For any reason, do not disable the unit to avoid
nuisance alarms.
˙When air streams passing by kitchens, the way how a smoke
detector can sense combustion particles in normal air-flow paths is
graphically shown in Figure 6, which indicates the correct and
incorrect smoke detector locations concerning this problem.

LOC ATIO NS T O AVOID AIR ST REAMS
WI TH COMB USTI ON PAR TIC LES

˙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 detectors, it will not work properly. The temperature
range for your smoke detector is 0℃~49℃.
˙In very dusty or dirty areas, dirt and dust can build up on the
detector’s sensing chamber, to make it overly sensitive. Additionally,

4 5 6

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 . See Figures 4 and 5 for recommended mounting
locations.
˙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.

WARNING: Never remove battery from smoke detector to stop a
nuisance alarm. Open a window or fan the air around the smoke
detector to get rid of the smoke. The detector will turn itself off when
the smoke is gone. If nuisance alarms persist, attempt to clean the
smoke detector as described in this User Manual.

WARNING: Do not stand close to the smoke 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.

INSTALLING YOUR SMOKE DETECTOR
LS-134H smoke detector is made to be mounted on the ceiling or on
the wall if necessary.

WARNING: Do not connect LS-134H smoke detector to any other
detector or auxiliary device. Connecting anything else to this detector
will keep it from working properly.

˙Hold fire drills at least every 6 months to make sure that everyone,
even small children, knows what to do to escape safely.
˙Know where to go to call the Fire Department from outside your
home.
˙Provide emergency equipment, such as fire extinguishers, and teach
your family to use this equipment properly.

MORE TIPS TO FACE A FIRE IN YOUR HOME
If you have made a family escape plan and practiced it with your
family, you have increased their chances of escaping safely. Go over
the following rules with your children each time you have fire drills.
This will help everyone remember them in case of a real fire
emergency.

1. Don’t panic and stay calm. Your safe escape may depend on
thinking clearly and remembering what you have practiced.

2. Get out of the house as quickly as possible. Follow a planned escape
route. Do not stop to collect anything or to get dressed.

3. Feel the doors to see if they are hot. If they are not, open them
carefully. Do not open a door if it is hot. Use an alternate escape route.

4. Stay close to the floor. Smoke and hot gases rise.

5. Cover your nose and mouth with a wet or damp cloth. Take short,
shallow breaths.

6. Keep doors and windows closed. Open them only if you have to in
order to escape.

7. Meet at your planned meeting place after leaving the house.

8. Call the Fire Department as soon as possible from outside your
house. Give the address and your name.

9. Never go back inside a burning building. Contact your local Fire
Department. They will give you more ideas about how to make your
home safer from fires and how to plan your family’s escape.

LIMITATIONS OF SMOKE DETECTORS

home. The built-in test switch accurately tests all functions as required
by Underwriters’ Laboratories. They are the only correct ways to test
the unit.

WARNING: When you are not testing the unit and the alarm horn
sounds this means the smoke 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.

NOTE: Do not disconnect the power or remove the battery from the
smoke detector. This will remove your protection from fires.
˙If the alarm horn begins to beep once in 43 seconds with red LED
flashing, this signal means that the smoke alarm’s battery is weak.
Replace new battery immediately. Keep fresh batteries on hand for
this purpose.

NOTE: Use only the replacement batteries listed below:
(Duracell) DL123A, (Panasonic) CR123A 3V with minimum life time
as long as 1 years under normal operation.

WARNING: Do not use any other kind of battery. This smoke alarm
may not operate properly with other kind of battery.

BATTERY INSTALLATION

1. Open battery compartment (see figure as below)

2. Install battery into compartment and make sure the “+” and “-“ ends
of each battery are aligned properly.

3. After battery is installed in compartment, you will hear a chirp
