When you change your clocks back 1 hour before bed tonight (or tomorrow morning), be sure to test all the smoke/carbon monoxide alarms in your home to make sure they are functioning properly.
Batteries should be replaced at least twice a year (each time you change your clocks) and the unit itself should be replaced every 10 years (5 years for carbon monoxide alarms). To determine the age of your alarm, look at the back where you will find the date of manufacture.
For the best possible protection, smoke alarms should be installed inside each bedroom, outside each sleeping area and on every level of the home, including the basement.
Working smoke alarms save lives!
