INTRODUCTION 400 SERIES
The 400 Series smoke alarm is a photoelectric type unit for use
as an evacuation device in residential applications. Each smoke
alarm has a temporal horn 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.
MODELS
(SEE BACK OF SMOKE ALARM FOR EXACT MODEL)
400............................120 VAC, 60Hz with Temporal Horn
Per NFPA 72, the American National Standard Audible Emergency
Evacuation Signal as defined in ANSI S3.41, is required whenever the
i
ntended response is to evacuate the building.
OPTIONS, SELECTIONS
T - Integral 135°F Thermal Sensor
TR - Integral 135°F Thermal Sensor and 1FormA/1Form C
Aux. Relay with Tandem Wire Connection.
NOTE: In the event AC Power fails, a 9v battery will provide proper
smoke alarm operation for a minimum of 24 hours.
HOW YOUR SMOKE ALARM WORKS
The 400 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 device 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 and sound the electronic
horn.
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 smoke alarm is provided with an alarm horn and pulsating
Light Emitting (indicator) Diode, which pulses every 30 seconds,
and a green AC power on LED.
When turning the test knob on the alarm to TEST 1 the red light
emitting diode should flash rapidly and the horn should sound.
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.
NOTE: Tandem Interconnect Models.
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 smoke alarm horn with their red
indicator lights remaining off. The relays will also activate on all
units in tandem on models equipped with the relay option.
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 up 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
smoke alarm 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.
