EDIT: There are 7 total Fire Alarms in this house. Apparently only 4 were trouble makers. Hubs is changing the batteries in all the ones we can reach.
Also, has been brought to our attention that Fire Alarms also have expiration dates. Like car seats. They are only meant to be used for X amount of years. So make sure yours are in date every year. If there in date replace the batteries every year.
