The battery-powered smoke alarm from First Alert features a mute function that silences nuisance alarms caused by cooking smoke or shower steam. A single button also tests the alarm's functions. The easy-access battery drawer eliminates the need to remove the alarm from the ceiling to change the battery. This smoke alarm comes with a 10-year limited warranty and meets UL standards. When activated, an optional theft-prevention lock ensures that the batteries and/or alarm cannot be removed without the proper tools.

Working smoke alarms reduce the risk of dying in a home fire by 50%, which is crucial as a home fire starts every 83 seconds. The faster you become aware of a fire, the quicker you can evacuate your family. The First Alert smoke alarm with a silence button allows you to silence a non-threatening alarm and test the unit's functionality. It features a low battery alert to remind you when to replace the battery and a missing battery guard to ensure the alarm is properly powered. The side battery drawer slides open for easy battery replacement, and a blinking power indicator confirms the unit is receiving power.

For tamper resistance, the alarm contains an optional pin to lock the battery and unit in place. It can be mounted on the ceiling or wall and is suitable for use in mobile homes and RVs. The smoke alarm includes a 9-volt battery and has a 10-year limited warranty. It is UL listed for safety.

The package includes one smoke alarm, a user's manual, and one 9-volt battery. This ionization sensor-based smoke alarm is effective at detecting smoke from flaming fires, such as those caused by paper or grease. As a battery-operated unit, it provides continuous monitoring even during power outages. The alarm features a single test/silence button, a side battery door, and a missing battery guard for added convenience and safety.

First Alert has been the most trusted brand in home safety since launching the first residential smoke alarm in 1958, according to a brand trust survey conducted in February 2018. To ensure complete protection, it is recommended to place one of these alarms on each level of your home and in each bedroom.
