How do you test smoke detectors?
Press and hold the test button on the smoke detector. It can take a few seconds to begin, but a loud, ear-piercing siren should emanate from the smoke detector while the button is pressed. If the sound is weak or nonexistent, replace your batteries.
How long is a smoke alarm test?
You can test your smoke alarm by pushing the Test/Hush button on the cover and holding it down for a minimum of 5 seconds. This will sound the alarm if the electronic circuitry, horn and battery are working.
How do you test first alert?
Testing with the “Test” button helps ensure that your alarms have a reliable power source. Instructions: While wearing ear protection, press the Test/Silence button until you hear the test sequence. The test button is usually found on the side or top of your unit.
