Craziest thing I ever saw - sympathethic alarm
Came home one day. I hear that stupid alarm chirp that mean the battery is low on one of the smoke alarms. Can't tell which one it is since they are all chirping. I have a set of 5 Kiddie that are daisy chained. Replace the battery in each one. Damn thing is still chirping. Hours later I go to the basement where I have a seperate CO detector that is not hard wired to the smokes but is only 1 foot away from one of the smoke alarm, change the battery in that and the chirp ends.
Is this even possible?
Is this even possible?

On the inter-connected 120 volt/battery backup units........only the low battery unit should chirp....not all of them.
I get calls all the time for low battery chirps. My systems are hardwired to an alarm panel and have no batteries in them. There is always that one CO detector hiding somewhere with a low battery.
How do I charge a customer for a service call when it wasn't even one of my smoke heads.

That little piezo chirp carries in an amazing way. The sound sometimes seems to travel through the ductwork, under the right conditions.
There is also the simple fact that, generally, in a location all the backup batteries are a similar age, and it only takes one power failure to drop them all below that low battery threshold.
