INTRODUCTION 380 SERIES
The 380 Series smoke alarm is a photoelectric type alarm for use
as a life saving device in residential applications. Each smoke alarm
has a solid state piezo signal to warn and alert the household 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.

HOW YOUR SMOKE ALARM WORKS
The 380 Series 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 smoke 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 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 alarm.
This technique of verifying the smoke condition substantially
reduces the possibility of nuisance alarms.

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
device weekly and have it repaired or replaced 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.
• Know where to go to call the fire department from outside your
residence.
• Provide emergency equipment such as fire extinguishers and
teach your family to use this equipment properly.
d. 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.
