Alarms play an important part in keeping your home safe. Smoke alarms and other fire alarms can give you an early warning in case a fire breaks out somewhere in your house, which is why it’s recommended that you keep your alarms in working order. To make this easier, some homeowners opt for hardwired alarms which don’t require periodic battery changes to stay active; these alarms are powered by your home’s electrical wiring, so they’re always functional as long as you have power.

Unfortunately, these alarms sometimes go off when there isn’t a fire threat as well. While you don’t want your smoke alarm or other warning system to miss signs of an actual fire, it can be pretty frustrating if your alarm goes off all the time when there’s no actual danger. If you have issues with an alarm that seems to always be going off, here are a few things that might help.

Cleaning Your Alarms

If you have a smoke alarm that’s way too sensitive, especially if I didn’t used to be, then there’s a good chance that you need to clean it. Dust, dirt, and similar small particles are some of the most common causes of alarms becoming too sensitive over time. The reason that this occurs is that these small particles can interact with your alarm in the same way that smoke particles do, triggering its sensitive mechanisms. Carefully cleaning your alarm with canned air or using a vacuum designed for electronics use can remove the dust and restore the alarm to proper working order.

It’s worth noting that insects might also be part of the problem with your alarm, especially if there’s a bit of a dust buildup on the alarm unit. These may be cleared out when you blow the dust free from your alarm, but it’s possible that you’ll need to place insect baits or spray bug spray on the wall near your alarm to help get rid of them. Just make sure that you don’t spray the alarm itself, and keep in mind that even spraying near the alarm might temporarily set it off.
