READ CAREFULLY AND SAVE
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.
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.
DESCRIPTION
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
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.
