Smoke Alarms may not operate properly because of a dead or weak battery, a build-up of dirt, dust or grease on the Smoke Alarm cover, or installation in an improper location. Clean the Smoke Alarm as described in “Regular Maintenance,” and then test the Smoke Alarm again. If it fails to test properly when you use the test button, or if the problem persists, replace the Smoke Alarm immediately. If you hear a “chirp” about once a minute, replace the Smoke Alarm. If you experience frequent non-emergency alarms (like those caused by cooking smoke), try relocating the Smoke Alarm. If the alarm sounds when no smoke is visible, try cleaning or relocating the Smoke Alarm. The cover may be dirty. If the alarm does not sound during testing, make sure the power pack activating lever is pushed all the way securely.
