While I was in the shower. No idea what is beeping. Probably not the alarm in my bedroom, it was replaced.
There’s two alarms in my living room. The carbon monoxide alarm is blinking green. I assume that means the batteries are fine. The fire alarm in the living room, just got it’s battery changed. They could of used a old battery.
Could be one of the UPSes, there’s three.
Maybe the beeping is outside.
