Daylight saving time begins March 12, which is the ideal reminder for homeowners to check their smoke alarms while setting clocks forward.
State law from 2013 requires that battery-operated smoke alarms be replaced every 10 years from the date of manufacture. The devices should also be tested at least once a month.
State law also calls for older smoke alarms to be replaced with new, sealed, long-life battery-powered smoke alarms by no later than Jan. 1, 2018, or when there is a change of tenant, test failure or a building permit is issued.
Hardwired 120-volt electric smoke alarms should be replaced every 10 years with new 120-volt smoke alarms with battery backup to ensure proper and timely operation in a fire. Homeowners with hardwired smoke alarms should not replace their devices with battery-powered alarms.
Fire code-compliant smoke alarms can be purchased at most home improvement stores.
