Hi folks, this Sunday, March 8th we start day light saving time. This is the perfect time, if you have a smoke alarm or carbon monoxide alarm with replaceable batteries to change them. It's also a good time to check the expiry date of your smoke alarm or carbon monoxide alarm. And don't forget to test your smoke alarm or carbon monoxide alarm.
Following is information to help make sure all smoke alarms have working batteries, accounting for the multiple types of smoke alarms on the market and their varying battery requirements:
Smoke alarms with non-replaceable 10-year batteries are designed to remain effective for up to 10 years. If the alarm chirps, warning that the battery is low, replace the entire smoke alarm right away.
Smoke alarms with any other type of battery need a new battery at least once a year. If that alarm chirps, warning the battery is low, replace the battery right away.
When replacing a battery, follow manufacturer’s list of batteries on the back of the alarm or manufacturer’s instructions. Manufacturer’s instructions are specific to the batteries (brand and model) that must be used. The smoke alarm may not work properly if a different kind of battery is used.
