INTRODUCTION

The 7139CS and 7139LS smoke alarms are photoelectric type alarms for use as an

evacuation device in commercial and commercial residential applications. Each smoke

alarm has a solid state piezo to warn and alert the household to the presence of threatening

smoke as well as a visual signal to warn and alert the hearing impaired to the presence of

threatening smoke.

Your photoelectric smoke 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.

BASIC SAFETY INFORMATION

Dangers, Warnings, Cautions and Notices alert you to important operating

procedures or to potentially hazardous situations. Pay special attention to these items.

w This photoelectric smoke alarm is listed for use in single-family and multi-family

residences, along with hotels, motels and other commercial residential

occupancies.

This photoelectric smoke alarm must receive continuous 120VAC, 60Hz, pure sine

wave electrical power (battery is meant for emergency back-up only). In order for

the emergency battery back-up to work, a new battery must be properly installed

(see BATTERY INSTALLATION section).

NEVER ignore your smoke alarm if it sounds. Refer to IF YOUR SMOKE ALARM

SOUNDS section for more information. Failure to do so can result in serious injury

or death.

Test this device once a week per manufacturer installation recommendation. If the

device ever fails to test correctly, replace immediately! If the device is not working

properly, it can not alert you to a problem.

This product is intended for use in indoor locations of family dwelling units.

MODELS

* 7139CS-W or C..............120VAC, 60Hz with 1 Form C Aux. relay contact, pulsating

temporal 3 sounder and visual signal with tandem wire

connection. Model is also provided with an additional wire (grey)

for the remote activation of the visual signal.

* 7139LS.......................... 120VAC, 60Hz wall mounted, provided with a 9 foot line

cord, pulsating temporal 3 sounder and visual signal.

* Per NFPA 72, the American National Standard Audible Emergency Evacuation Signal as

defined in ANSI S3.41, is required whenever the intended response is to evacuate the

building.

NOTICE: VISUAL SIGNALS ARE ONLY ONE METHOD OF ALERTING THE HEARING IMPAIRED. NOT

ALL HEARING IMPAIRED INDIVIDUALS WILL BE ALERTED BY VISUAL SIGNALS.

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 smoke 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 smoke

alarm is put into a pre-alarm mode. This is indicated by a rapidly flashing LED on the face

of the smoke alarm. Once the light sensor confirms smoke for 2 consecutive pulses inside

the chamber, the light sensor produces the signal necessary to trigger the smoke 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

w Your smoke 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.

w When turning the test knob on the alarm to TEST 1, the red light will flash rapidly, the

horn will sound and the visual signal will flash.

Visual signal will not operate without AC power

w If the battery is low or missing, a chirp will be emitted when the red LED flashes. If the

smoke alarm is malfunctioning, the chirp will sound between the red LED flashes. If AC

power fails, the green LED will turn off.

w The test knob of your smoke alarm simulates actual smoke conditions.

NOTE: TANDEM INTERCONNECT MODELS

w When testing one smoke alarm, the smoke alarm that is activated will flash the red

indicator light and sound its alarm horn. All other units will sound the alarm horn with

their red indicator lights remaining off.

FIRE PROTECTION PLAN: WHAT YOU CAN DO TO MAKE YOUR

FAMILY SAFE FROM FIRES

This smoke alarm can quickly alert you to the presence of smoke; but cannot prevent fire.

The ultimate responsibility for fire protection rests solely on you.

Installing 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 devices weekly and have unit repaired or replace

unit when it no longer functions. As with any electronic product, smoke alarms have a

limited life, and devices that don't work cannot protect you.

b. Follow safety rules and prevent hazardous situations:

w Use smoking materials properly; never smoke in bed.

w Keep matches and cigarette lighters away from children.

w Store flammable materials in proper containers and never use them near open flames or

sparks.

w Keep electrical appliances and cords in good working order and do not overload electrical

circuits.

w Keep stoves, fireplaces, chimneys, and barbecue grills grease-free and make sure they

are properly installed away from combustible materials.

w Keep portable heaters and open flames such as candles away from combustible

materials.

w Do not allow rubbish to accumulate.

w Do not leave small children home alone.

c. Develop a family escape plan and practice it with your entire family, especially small children. w Draw and post 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. w Teach children what the smoke alarm signal means, and that they must be prepared to leave the residence by themselves if necessary.

Never remove power from smoke alarm to silence a nuisance alarm. Open a window or fan air around device to remove the smoke. The smoke alarm will automatically turn off when the smoke in the air is completely gone. Do not stand close to device. The sound produced by the smoke alarm is loud because it is designed to awaken you in an emergency. Prolonged exposure to the horn at a close distance may be harmful to your hearing. Use a 2" x 3" switch box or a 4" square or octagon junction box.

c. To test unit for high sensitivity, turn test knob clockwise to TEST 2 position. Smoke alarm should remain silent. Return knob back to normal position. If the unit sounds during test, the device’s sensitivity has become too high and may cause false alarms. This could mean the smoke alarm is dirty and should be cleaned as described in maintenance procedure below. If the smoke alarm continues to alarm for TEST 2 position following cleaning return it to Gentex for service. d.
