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.
