I try not to bug you guys but I'm stumped with this. The house has 9 BRK smokes and 2 CO/Smoke combos interconnected 110V with battery backup. In the middle of the night it seems they go into alarm for about 3 seconds, when the homeowner kills the 110V and they run on battery they are fine .
I thought maybe a power company switchover in the middle of the night but nothing else shows signs of that, time clocks etc. The detectors are about 6 years old... I also vacuumed them and tested everything seems right. I replaced the CO/Smoke combo on a hunch but it didn't do anything to fix it.
I hesitate to replace them all just to have this issue reoccur. Any suggestions would be helpful
Thanks
