INTRODUCTION

The 713LS Smoke Alarm is a Photoelectric Type Alarm
for use as an evacuation device in residential applications,
while the 710LS is 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.

MODEL NO. DESCRIPTION

710LS* ...... 120 VAC Wall Mounted, Provided

With a 9 ft. Line Cord, Pulsating Horn

713LS ...... Same as 710LS but with a Temporal Horn

* This unit produces a non-temporal audible alarm and is therfore

not intended for locations where the desired action of the
occupant(s) is evacuation.

NOTE: Loss of electrical input will cause the alarm not to

function. For maximum safety you should install both
battery operated and AC powered smoke alarms.

HOW YOUR SMOKE
ALARM WORKS

The 710LS/713LS Smoke Alarm operates 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 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 pre-alarm 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 LED will rapidly flash, the horn will sound and the
strobe light will flash. If AC power fails, the green LED
will turn off.

· The test knob of your alarm simulates actual smoke

conditions.

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

If the smoke alarm should sound:

1. Never waste time dressing or gathering valuables.

with the smoke alarm so they can react properly.

Follow the escape route and leave the house
immediately.

Pg. 7-1

2. Check bedroom doors before opening. If the door is
hot or smoke is leaking in around the edges-DO NOT
OPEN-use the alternate escape route.

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 out
side 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

outside 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. Battery-

operated alarms will not work without batteries, with dead
batteries, or if the batteries are not installed properly. AC
powered alarms will not work if their AC power supply is cut
off by an electrical fire, an open fuse or circuit breaker, or for
any other reason. If you are concerned about the reliability of
either the batteries or your AC power supply for any of the
above reasons, you should install both battery and AC
powered alarms for maximum safety.

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, i f 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
special-purpose fire detection and alarm systems necessary
to protect persons and property in non-residential buildings
such as warehouses, or other large industrial or commercial
buildings. It alone is not a suitable substitute for complete
fire-detection systems designed to protect individuals in hotels
and motels, dormitories, hospitals, or other health and
supervisory care and retirement institutions. Please refer to
NFPA 101,The Life Safety Code, and NFPA 72 for smoke
