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.
MODEL NO. DESCRIPTION
7109CS/CSX-W or C*.....120 VAC, 60 Hz with 1 Form C
Aux. Relay Contact and Visual
Signaling Strobe Light with Tandem
Wire Connection. CSX model is
provided with an additional wire (grey)
for the remote activation of the strobe.
7109LS*..........................120 VAC, 60 Hz Wall Mounted,
Provided With a 9 ft. Line Cord,
Pulsating Horn.
7139CS/CSX-W or C......Same as the 7109CS but with a
Temporal Horn. CSX model is
provided with an additional wire (grey)
for the remote activation of the strobe.
7139LS...........................Same as 7109LS but with a
Temporal Horn.
* These units produce a non-temporal audible alarm and are therefore not
intended for locations where the desired action of the occupant(s) is
evacuation.
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 sen-
sor. At the first sighting of smoke, the alarm is put into a pre-
alarm mode.

7139CS/CSX & 7139LS
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 OPEN-
use the alternate escape route.
