It’s common knowledge that batteries need to be changed in smoke detectors. A good rule of thumb is to check/change them in the spring and fall – when clocks are adjusted for daylight savings time. But what if your smoke detectors are hard-wired?
You may not know it, but smoke detectors have a limited life span. Eventually, the sensors wear out and they lose their ability to detect smoke. For this reason, fire safety experts suggest completely replacing smoke detectors every 10 years. This goes for battery and hard-wired models.
After 10 years, it may be difficult to remember that this change should take place, so be sure to create some kind of reminder for yourself that won’t get lost or fail to alert you. Setting a reminder on your phone or with an online calendar is a good idea. Multiple reminders are also recommended – in case one fails.
