INTRODUCTION
The 380LSb smoke alarm is a photoelectric (optical) type alarm
for use as an evacuation device in 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 (optical) 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.
MODEL NO.
DESCRIPTION
*380LSb.......................... 120VAC with 9VDC battery backup, 60Hz
wall mounted, provided with a 9 foot line
cord, temporal 3 horn 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 (optical) 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.
HOW TO TELL IF YOUR SMOKE ALARM IS
WORKING PROPERLY
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.
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.
WARNING! Visual signal will not operate without AC power.
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.
The test knob of your smoke alarm simulates actual smoke
conditions.
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-it 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 repair or replace it 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:
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.
Do not leave small children home alone.
c. Develop a family escape plan and practice it with your entire
family, especially small children.
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.
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.

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.
