INTRODUCTION 913 SERIES
The 913 Series smoke alarm is a photoelectric type device for use as an
evacuation 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.
BASIC SAFETY INFORMATION
Dangers, Warnings, Cautions and Notices alert you to important operating
procedures or to potentially hazardous situations. Pay special attention to these
items.
This photoelectric smoke alarm is listed for use in single-family and
multi-family residences, along with hotels, motels and other commercial
residential occupancies.
NEVER ignore your smoke alarm if it sounds. Refer to IF YOUR SMOKE
ALARM SOUNDS section for more information. Failure to do so can result in
serious injury or death.
Test this device once a week per manufacturer installation recommendation.
If the device ever fails to test correctly, replace immediately! If the device is
not working properly, it can not alert you to a problem.
This product is intended for use in indoor locations of family dwelling units.

HOW YOUR SMOKE ALARM WORKS
The 913 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 unit.
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 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.
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; but 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 alarm weekly and have unit
repaired or replace alarm when it no longer functions.
As with any electronic
product, 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 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.
