You should test your smoke alarms monthly by pressing the test button to ensure they are functioning correctly.

Regularly testing your smoke alarms is a critical part of home safety. Press the test button on each unit once a month to verify that the power, battery, and alarm mechanisms are all working. This simple action can confirm the device is operational and will alert you in case of a fire. If an alarm fails the test, it's important to address it immediately by replacing the battery or the unit itself.

This information provides general guidance on smoke alarm maintenance and testing.

What type of battery does a smoke alarm use?

Myinfiniteinsights

Most battery-operated smoke alarms use standard alkaline batteries, commonly 9-volt or AA sizes. However, some models may specify different types, such as lithium batteries, for longer life. Always check the label on your smoke alarm or consult its manual to determine the exact battery type and size required. Using the wrong battery can prevent the alarm from functioning correctly or may cause damage to the unit.
