A wireless ADT smoke detector protects the home and also tells the panel, so a reset can mean two different jobs, clearing the detector's own chirp or fault, or removing it from the panel and enrolling it again. Treat them separately. A detector that chirps, flashes or sounds with no smoke may be signalling a low battery, an end-of-life warning or dust in the chamber. The usual way to clear its own state is to remove the battery, hold the test button for about fifteen to thirty seconds to drain the stored charge, refit the battery and test it, as the manual describes.
The checks in more detail
The NFPA says to test smoke alarms monthly and to replace them about every ten years, so a chirping detector over ten years old should be replaced, not reset. Check the date on the back. To clear it from the panel or enrol it again, put the panel into sensor or zone programming, which usually needs the installer or master code, delete the old entry, then add the detector by triggering its enrolment, often by reinserting the battery or pressing a learn or test button as the manual says. The panel confirms with a beep or a message, and you name the zone and set it as a fire zone.
SafeWise's guide notes the sequence varies by panel model, so identify yours first. Clean the detector gently with a vacuum brush or compressed air, since dust and insects cause false alarms, and make sure it is not next to a kitchen, a bathroom or a vent. Tell the monitoring company before testing, so they do not dispatch the fire service. If a detector will not stop alarming, replace it. Never disable a smoke detector, and do not leave a home without working ones. A reset of the whole panel is for the installer.
After any reset, test the alarm sound, because a detector that is silent in test needs replacing whatever the panel says. Press and hold the test button until the alarm sounds, stand a safe distance away since it is loud, and have everyone in the house hear it so that they know what it means. Plan an escape route and a meeting point, since the best detector only helps if people know what to do. If the detector is hard-wired as well as wireless, switch off the circuit before removing it from the ceiling, and use a qualified electrician for any wiring.
