INTRODUCTION
The 7139CS/CSX & 7139LS Smoke Alarms are
Photoelectric Type Alarms for use as an evacuation device in
residential applications, while the 7109CS/CSX &7109LS are
for use as an alert and relocate device. Each alarm has a solid
state piezo signal to warn and alert the household to the
presence of threatening smoke.
Your Photoelectric alarm is designed to detect the smoke
that results from an actual fire. Consequently, it is uncommon
for household smoke such as cigarette smoke or normal
cooking smoke to cause an alarm.

HOW YOUR SMOKE
ALARM WORKS
These Smoke Alarms operate on the photoelectric light
scatter principle. The unit's sensing chamber houses a light
source and a light sensor.
The darkened sensing chamber is exposed to the
atmosphere and designed to permit optimum smoke entry from
any direction while rejecting light from outside the alarm.
The light source is an infrared (invisible) LED which pulses
every 4-8 seconds. The light sensor is a photodiode matched
to the light frequency of the LED light source.
Under normal conditions, the light generated by the pulsing
infrared LED is not seen by the light sensor, as it is positioned
out of the direct path of the light beam. When smoke enters
the sensing chamber, light from the pulsing LED light source is
reflected by the smoke particles onto the photodiode light sensor. At the first sighting of smoke, the alarm is put into a prealarm mode.
This is indicated by a rapidly flashing LED on the face of the
alarm. Once the light sensor confirms smoke for 2 consecutive
pulses inside the chamber, the light sensor produces the signal
necessary to trigger the alarm.
This technique of verifying the smoke condition, combined
with a 5-to-1 signal-to-noise ratio, substantially reduces the
possibility of nuisance alarms.
HOW TO TELL IF YOUR SMOKE
ALARM IS WORKING PROPERLY
§ Your alarm is provided with an alarm horn and pulsating
Light Emitting (indicator) Diode, which pulses every 15-30
seconds, and a green AC power on LED.
§ When turning the test knob on the alarm to TEST 1, the red
light will flash rapidly, the horn will sound and the strobe will
flash. Strobe will not operate without AC power.
§ If the battery is low, a chirp will be sounded when the red
LED flashes. If the alarm is malfunctioning, or if the battery
is missing, the chirp is sounded without the red LED flashing.
If AC power fails, the green LED will turn off.
§ The test knob of your alarm simulates actual smoke
conditions.
NOTE: Tandem Interconnect Models.
§ When testing one alarm, the alarm that is activated will
flash the red indicator light emitting diode and sound its
alarm horn. All other units will sound the alarm horn with
their red indicator lights remaining off.
FIRE PROTECTION PLAN
This Smoke Alarm can quickly alert you to the presence of
smoke-it cannot prevent fire. Please note that there are
hazards against which smoke detection may not be effective,
such as smoking in bed, explosions, when a closed door
separates the alarm from the source of the smoke, etc. The
ultimate responsibility for fire protection rests solely on you.
1. To minimize fire hazards-avoid improper storage of
flammable liquids and don't leave small children home
alone.
2. Bedroom doors should be closed while sleeping if a
smoke alarm is installed in the bedroom. They act as a
barrier against heat and smoke.
3. Establish an escape plan:
(a) Post a detailed floor plan depicting the chosen escape
routes.
(b) Each bedroom should have at least two escape routes.
(c) Make sure your children know what to do in case of
fire and teach them to follow the escape plan you
have posted.
(d) Agree on an outside meeting place.
(e) Conduct fire drills at least twice a year.
(f) Be sure each member of the family is familiar with
the smoke alarm so they can react properly.
If the alarm should sound:
1. Never waste time dressing or gathering valuables. Follow
the escape route and leave the house immediately.
2. Check bedroom doors before opening. If the door is hot
or smoke is leaking in around the edges-DO NOT OPENuse the alternate escape route.
Pg. 7-1
3. If there is smoke in the escape route-keep close to the
floor and take short breaths. If possible, cover your nose
and mouth with a wet cloth.
4. Do not use your own telephone-call the Fire Department
from your neighbor's house.
5. Once out, do not re-enter your house, but proceed to
your prearranged meeting place.
WHAT ELSE YOU CAN DO TO MAKE
YOUR FAMILY SAFE FROM FIRES
Putting up smoke alarms is just the first step in protecting
your family from fires. You also must reduce the chances that
fires will start in your home and increase your chances of safely
escaping if one does start. To have an effective fire safety
program:
a. Install smoke alarms properly following the instructions
in this manual. Keep your smoke alarms clean. Test
your alarm weekly and repair or replace it when it no
longer functions. As with any electronic product, alarms
have a limited life, and alarms that don't work cannot protect
you.
b. Follow safety rules and prevent hazardous situations:
§ Use smoking materials properly; never smoke in bed.
§ Keep matches and cigarette lighters away from children.
§ Store flammable materials in proper containers and
never use them near open flames or sparks.
§ Keep electrical appliances and cords in good working
order and do not overload electrical circuits.
§ Keep stoves, fireplaces, chimneys, and barbecue grills
grease-free and make sure they are properly installed
away from combustible materials.
§ Keep portable heaters and open flames such as candles
away from combustible materials.
§ Do not allow rubbish to accumulate.
c. Develop a family escape plan and practice it with your
entire family, especially small children.
§ Draw a floor plan of your home and find two ways to exit
from each room. There should be one way to get out of
each bedroom without opening the door.
§ Teach children what the smoke alarm signal means,
and that they must be prepared to leave the residence
by themselves if necessary. Show them how to check
to see if doors are hot before opening them, how to
stay close to the floor and crawl if necessary, and how
to use the alternate exit if the door is hot and should
not be opened.
§ Decide on a meeting place a safe distance from your
house and make sure that all your children understand
that they should go and wait for you if there is a fire.
§ Hold fire drills at least every 6 months to make sure that
everyone, even small children, know what to do to
escape safely.
§ Know where to go to call the fire department from outside
your residence.
§ Provide emergency equipment such as fire extinguishers
and teach your family to use this equipment properly.
WHAT TO DO IF THERE IS A FIRE
IN YOUR HOME
If you have prepared family escape plans and practiced
them with your family, you have increased their chances of
escaping safely. Review the following rules with your children
when you have fire drills so everyone will remember them in a
real fire emergency:
a. Don't panic; stay calm. Your safe escape may depend on
thinking clearly and remembering what you have practiced.
b. Get out of the house following a planned escape route as
quickly as possible. Do not stop to collect anything or to
get dressed.
c. Open doors carefully only after feeling to see if they are
hot. Do not open a door if it is hot; use an alternate
escape route.
d. Stay close to the floor; smoke and hot gases rise.
e. Cover your nose and mouth with a cloth, wet if possible,
and take short, shallow breaths.
f. Keep doors and windows closed unless you open them to
escape.
g. Meet at your prearranged meeting place after leaving the
house.
h. Call the Fire Department as soon as possible from out
side your house. Give the address and your name.
i. Never re-enter a burning building.
Contact your local Fire Department for more information
on making your home safer from fires and about preparing your
family's escape plans.
WHAT THIS SMOKE ALARM CAN DO
This alarm is designed to sense smoke entering its sensing
chamber. It does not sense gas, heat, or flames.
When properly located, installed, and maintained, this
smoke alarm is designed to provide early warning of
developing fires at a reasonable cost. This alarm monitors the
air and, when it senses smoke, activates its built-in alarm horn.
It can 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 alarm is located,
installed, and maintained as specified in this User's Manual.
NOTE: This smoke alarm is designed for use within
single residential living units only; 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 alarm 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, or in other apartments. In multi-family
buildings, each residential unit should have alarms to alert the
residents of that unit. Alarms designed to be interconnected
should be interconnected within one family residence only;
otherwise, nuisance alarms will occur when an alarm in another
living unit is tested.
IMPORTANT NOTE: WHAT SMOKE
ALARMS CANNOT DO
Smoke alarms will not work without power. A battery
must be connected to the alarm to maintain proper alarm
operation if AC power supply is cut off by an electrical fire, an
open fuse or circuit breaker, or for any other reason. In the
event of AC power failure, the battery will supply standby
power for a minimum of 24 hours.
Smoke alarms may not sense fire that starts where
smoke cannot reach the alarms such as in chimneys, in
walls, on roofs, or on the other side of closed doors. If
bedroom doors are usually closed at night, alarms should be
placed in each bedroom as well as in the common hallway
between them.
Smoke alarms also may not sense a fire on another
level of a residence or building. For example, a second-floor
alarm may not sense a first-floor or basement fire. Therefore,
alarms should be placed on every level of a residence or
building.
The horn in your alarm meets or exceeds current audibility
requirements of Underwriters Laboratories. However, if the
alarm is located outside a bedroom, it may not wake up a
sound sleeper, especially if the bedroom door is closed or only
partly open. If the alarm is located on a different level of the
residence than the bedroom, it is even less likely to wake up
people sleeping in the bedroom. In such cases, the National
Fire Protection Association recommends that the alarms be
interconnected so that an alarm on any level of the residence
will sound an alarm loud enough to awaken sleepers in closed
bedrooms. This can be done by installing a fire-detection
system, by connecting alarms together, or by using radio
frequency transmitters and receivers.
All types of smoke alarm sensors have limitations. No
type of smoke alarm can sense every kind of fire every
time. In general, alarms may not always warn you about
fires caused by violent explosions, escaping gas, improper
storage of flammable materials, or arson.
NOTE: This alarm is not designed to replace specialpurpose fire detection and alarm systems necessary to
protect persons and property in non-residential buildings such
as warehouses, or other large industrial or commercial build ings. It alone is not a suitable substitute for complete firedetection systems designed to protect individuals in hotels and
motels, dormitories, hospitals, or other health and supervisory
care and retirement homes. Please refer to NFPA 101,The Life
Safety Code, and NFPA 72 for smoke alarm requirements for
fire protection in buildings not defined as "households."
Installing smoke alarms may make you eligible for lower insurance rates, but smoke alarms are not a substitute for insur -
ance. Home owners and renters should continue to insure
their lives and property.
