6 units / 2 models all started beeping

Anonymous user · ‎2021-06-28

I have 6 units in my home office.

This morning i woke up to find all 6 beeping.

they are beeping 4 times about every 30 seconds. Every unit

i have some model 550 and some 750

it seems they r all running off battery

i cant get them to run on a/c

i tried powering on and off. Unplugging devices from unit. Unplugging unit from wall.

Pressing circuit breaker isnt doing anything

power did not go out last night

What is wrong and what am i to do?

It would be very odd for all of these units to have failed at once. Could a circuit breaker or something like a ground fault circuit interrupter have turned off power? (Does a lamp work if you plug it directly into the wall outlets in question?)

If you have access to a voltmeter that can safely measure AC powerline voltage, you could measure the voltage present at the wall outlets.

When i try to press circuit breaker it does not feel like it is clicking or anything... Feels like no spring or anything like that... Doesnt really go in or out
