Home has like 6 smoke alarms throughout the home, connected with a signal wire (i.e. if one beeps, they all go off.)
They're First Alert, AC powered + battery backup + signal wire.
Master bedroom few months back did a slow beep, indicating low battery. So I replace the AAA batteries. No dice. Swapped it with other ones in the home, no dice, seems to be a defective alarm? Manufacture date seems in-line; not expired.
Finally picked up a new one (with non-removable lithium battery), and same shit -- flashing green, 5 beeps every min, indicating low battery.
Also replaced the leads/connector (white, black, orange signal wire), no dice. Pressed the test button on the new one while it was connected --- whole house went crazy. So, we know the signal wire def works. I'll lick a finger and put it on the black wire?
Thoughts? FML...
I'm this close to just closing up the hole with a cover and saying fuck it.
Summary: - Existing hard-wired smoke alarm indicates low battery. Replace batteries, swapped to another location in the home, replaced whole unit, no change. - Swapped out smoke alarm for new. Same shit. wtf.
The fact that BOTH units (new and old) exhibit the same shit, AND the old unit exhibits same shit at a different spot in the home seems to indicate some kind of wiring issue... FML....
