Time to "Retire" Your Smoke Alarms?

Your smoke alarms need to have a retirement plan! Smoke alarms have a life expectancy of 10 years and then need to be replaced with new ones. Like other electronic equipment, smoke alarm components wear out over time and the sensors can begin to lose sensitivity. The test button only confirms that the battery, electronics and the alert system are working, not that the sensor that detects smoke is working. 

Remember:

- Even if your 10-year-old (or older) smoke alarm sounds when you push the test button, it still needs to be replaced.

- Even if a smoke alarm hasn’t reached the 10-year mark, replace it if it chirps after you’ve replaced the battery or if the alarm doesn’t sound when you perform the recommended monthly testing of your fire alarm system.

- Montgomery County Fire Officials recommend replacing all interconnected smoke alarms at the same time (even if some are working).

Remember: smoke alarms are an essential part of your home's fire prevention strategy! Be sure to read about Maryland's New Smoke Alarm law that affects all battery-only smoke alarms.
