One of the last things we think about are smoke and CO alarms, especially since our communities alarms are wired into the electricity in the house. But this post is a reminder to check the backup batteries in your alarms. Each of our smoke and CO alarms has a 9 volt battery in the device as a backup in case the power goes out. These batteries weaken over time and need to be replaced. Usually there is a periodic chirping sound to indicate the battery is dying. If the batteries aren’t replaced the system can indicate a failure and have all the smoke alarms go off simultaneously (indicating a whole house fire). Since no one wants to experience this potentially upsetting false alarm please change your batteries in your alarms every 2 years and immediately when you hear a chirp.
And PLEASE remember if all the smoke alarms go off in the house ASSUME the WORST and take precautions, its better to be safe than sorry.
