Installation Instructions - Owner's/User's Information Manual



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.



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.


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.


·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.


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 smoke 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 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.


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.


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.


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.


Smoke alarms will not work without power. Batteryoperated 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, 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 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.
