Smoke detectors followup

We talked to one of the guys at the fire station and he says this is how modern, whole house smoke detectors react when their batteries get low. We thought we had changed them before, but we hadn't - they were all holding Kidde branded batteries. We changed them all. Interestingly, two had AA batteries and the rest all had 9-volts.

Hopefully we will have no more of this false alarm stuff.

The fireman also said that it is true, what they say online - they get two or three calls a week about situations like ours and they are happy to troubleshoot smoke detectors, and don't be afraid to just call.
