INTRODUCTION GN-300 SERIES
The GN-303 Series smoke alarm is a photoelectric type unit for
use as an evacuation device in residential and commercial residential
applications, while the GN-300 Series are for use as an alert and
relocate device. 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.
WARNING!
This photoelectric smoke alarm is listed for use in single-family and
multi-family residences, along with hotels, motels and other
commercial residential occupancies.
This photoelectric smoke alarm must receive continuous 120VAC,
60Hz , pure sine wave electrical power.
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.
MODELS
(SEE BACK OF SMOKE ALARM FOR EXACT MODEL)
* GN-300..........................120 VAC, 60Hz
**GN-303..........................120 VAC, 60Hz with temporal horn
* These units produce a non-temporal audible alarm and are therefore not
intended for locations where the desired action of the occupant(s) is
evacuation.
** 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: 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 GN-300 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.
GN-300 & GN-303
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 red 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 device and sound the electronic horn.
HOW TO TELL IF YOUR SMOKE ALARM IS
WORKING PROPERLY
Your smoke alarm is provided with an alarm horn and flashing red
Light Emitting Diode (LED) indicator, which flashes every 15-30
seconds, and a green AC power on LED.
Test button function: when test button is pressed, the full operation
of the light source and light sensor is checked and will initiate an
alarm.
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.
NOTE: Tandem Interconnect Models.
When testing one smoke alarm, the device that is activated will flash
the red indicator light and sound its alarm horn. All other units will
sound the alarm horn with their red indicator lights remaining off.
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 units clean. Test your smoke alarm weekly
and have unit repaired or replace unit when it no longer
functions. As with any electronic product, smoke alarms have a
limited life, it is recommended that smoke alarms be replaced every
ten years. Smoke alarms 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.
