OPERATION, TESTING & MAINTENANCE
OPERATION: The smoke alarm is operating once the battery is connected. When
products of combustion are sensed, the unit sounds a loud alarm which continues
until the air is cleared.
This alarm incorporates the internationally recognized "temporal tone" horn signal for
evacuation. During alarm mode, the horn produces three short beeps followed by a
two second pause and then repeats.
STANDBY CONDITION: The red LED flashes once every 40-60 seconds to indicate
the unit is properly functioning.
LOCAL ALARM CONDITION: The red LED flashes rapidly and the unit emits a loud,
pulsating alarm sound.
TESTING: Test by pushing the test button on the smoke alarm cover until the alarm
sounds, then release. The alarm sounds if all electronic circuitry, horn and battery are
working. The alarm may continue to sound for up to 10 seconds after the button is
released. If no alarm sounds, the unit may have a defective battery or other failure.
Test the smoke alarm weekly to assure proper operation.
Early warning fire detection is best achieved by the installation of fire detection
equipment in all rooms and areas of the household as follows: A smoke alarm
installed in each separate sleeping area (in the vicinity of, but outside of, the
bedrooms) and heat or smoke alarms in living rooms, dining rooms, kitchens,
hallways, attics, furnace rooms, closets, utility storage rooms, basements and
attached garages. Test the smoke alarm weekly to assure proper operation.

NEVER use an open flame of any kind to test this unit. You might accidentally
damage or set fire to the unit or to your home. The built-in test switch accurately
tests the unit's operation as required by Underwriters Laboratories Inc. (UL).
If you choose to use an aerosol smoke product to test the smoke alarm, be
certain to use one that has been Listed to Underwriters Laboratories, Inc. Safety
Standards and use it only as directed. Use of non-UL Listed products or improper
use of UL Listed products may affect the smoke alarm's sensitivity.
MAINTENANCE: The smoke alarm is virtually maintenance free. However, under
dusty conditions, a vacuum hose may be used to clear the sensing chamber of dust.
BATTERY REPLACEMENT
The smoke alarm uses a 9 Volt carbon-zinc battery. The battery should last for at
least one year under normal operating conditions. The smoke alarm has a low battery
indicator, an audible "beep." It will operate at 30-40 second intervals for a minimum of
7 days. When this indication occurs, replace the battery with an Alkaline type (Eveready
Energizer #522, Duracell #MN1604), Carbon-Zinc type (Gold Peak #1604P, Eveready
#216).
REPAIRS AND SERVICES
If the smoke alarm is defective in any way, do not tamper with the unit. Return the unit
for servicing. (See warranty for instructions or in-warranty returns.) There will be a
service charge for repairing out of warranty units.
