3. In dusty areas. Dust particles may cause nuisance alarm or failure alarm.
4. In insect-infested areas.
5. Within 3 ft (.9m) of the following: the door to a kitchen, the door to a bathroom containing a tub or shower.
6. In the room where the humidity exceeds the allowable value.

When products of combustion are sensed, the unit sounds with 80db pulsating alarm until the air is cleared.

The loud alarm can be hushed by pressing the test button in the cover. It can only be muted if the detector first sounds an alarm.

Test by pressing the test button on the cover and holding it down for a minimum of 1 seconds (or until the alarm sounds).The alarm sounds if the electronic circuitry, horn, and battery are working. If no alarm sounds, the unit has battery fault or other faults. DO NOT use an open flame to test your detector, as it may damage the alarm or ignite combustible materials, causing a structure fire.

YOUR DETECTOR SHOULD BE CLEANED AT LEAST ONCE A YEAR. To clean your smoke detector, remove it from the mounting bracket by twisting counter-clockwise. Cleaning the interior of the detector (sensing chamber) by compressed air or a vacuum cleaner hose and blowing or vacuuming through the openings around the perimeter of the detector. The external of the detector can be wiped with a damp cloth. After the cleaning, reinstall the detector and test it using the test button. If cleaning does not restore the detector to normal operation, the detector should be replaced.
