3V Lithium Battery Smoke Detector Alarm

Is the National Fire Protection Association of Canada (NFPA) correct in recommending that smoke alarms be replaced after 10 years?

Yes, smoke detectors have a finite lifespan. First Alert Smoke Alarms must are required to pass a series of tests to ensure persistent performance and reliability. And while they're designed to secure peace of mind, any part within a smoke alarm may fail as time progresses. It's therefore encouraged that detectors be tested once a week.

Smoke detectors that exceed the ten year limit are simply not reliable. To ensure overall safety, it's suggested that all carbon monoxide and combination detectors be replaced every 7 years. Smoke alarms should be replaced once every 10 years.

Don't forget! Once a smoke detector has surpassed its 10 year lifecycle, protection levels are diminished. Replace your old alarms with a new First Alert detector and eliminate any lingering doubts.
