If no alarm sounds, check the fuse or circuit breaker supplying power to
the alarm circuit. Verify that the green LED is on. If the alarm still does
not sound, the alarm may have defective batteries or other failure.
DO NOT use an open flame to test your alarm. You could damage the
alarm or ignite combustible materials and start a structure fire.
TEST THE ALARM WEEKLY TO ENSURE PROPER OPERATION.
Erratic
or low sound coming from your alarm may indicate a defective alarm,
and it should be returned for service (see section 11).
Smoke alarms are designed to minimize nuisance alarms. Cigarette
smoke will not normally set off the alarm, unless the smoke is blown
directly into the alarm. Combustion particles from cooking may set off
the alarm if the alarm is located close to the cooking area. Large
quantities of combustible particles are generated from spills or when
broiling. Using the fan on a range hood which vents to the outside (non-
recirculating type) will also help remove these combustible products from
the kitchen.
This model is equipped with a "Hush" feature that is extremely useful in
a kitchen area or other areas prone to nuisance alarms. For more
information, refer to section 4 OPERATION AND TESTING.
If the alarm does sound, check for fires first. If a fire is discovered, get
out and call the fire department. If no fire is present, check to see if one
of the reasons listed in section 2 may have caused the alarm.
CLEANING YOUR ALARM
YOUR ALARM SHOULD BE CLEANED AT LEAST ONCE A YEAR
To clean your alarm, remove it from the mounting bracket as outlined in
the next section. You can clean the interior of your alarm (sensing
chamber) by using compressed air or a vacuum cleaner hose and
blowing or vacuuming through the openings around the perimeter of
the alarm. The outside of the alarm can be wiped with a damp cloth.
After cleaning, reinstall your alarm and test your alarm by using the
Test/Hush button. If cleaning does not restore the alarm to normal
operation the alarm should be replaced.
