I took them down, immediately changed their batteries (9V
Duracell) and put them back into place. The beeps stopped.

Six of the eight units started beeping randomly. It daisy-chained
down the hallway in a weird march. The beeps were first 20 minutes
apart but have graduated to every 20 seconds now.

I've blown out each unit, tested them (and my ears are still
ringing), and put them back into place. Still, every 60-90
seconds, the damn things march down the hallway beeping away.

Thoughts or ideas to cure this annoying morning alarm?

Are these "tandem" detectors? you might have to take each down,
disconnect the tandem wire, then see which one is still beeping, then
replace that detector.

If they are above "a certain age" (what that is depends on your personal
comfort level) you may simply want to replace them all.

Yes; six per wire.

you might have to take each down, disconnect the tandem
wire, then see which one is still beeping, then replace that
detector.

sigh It couldn't possibly be easy. That just wouldn't be fun.

That was going to be my "final" solution.

Thanks for the answer.

I've worked for two different suppliers of fire alarms for large
commercial buildings, if you have any kind of trouble such that the
control panel doesn't tell you what it is, troubleshooting is Not Fun.
That's just a fact of life

It's funny what one does at 5am when awakened by this type of
activity. BTDT. Thank, though.

Some earplugs are better than others while troubleshooting. I like
the kind you roll between the fingers then insert into the ear canal
(works great in a school cafeteria). Have you called your local FD?
They often offer friendly help and/or suggestions. Find First Alert
customer support.

I have managed student housing with hardwired smokes for years. They
always fail between 3:00 and 5:00 AM. :-)

One thing you could try is to reset the alarms. Do this by disconnecting
the smoke alarm from the power and removing the battery. Then push the test
button for 30 - 60 seconds. Do this on all of them and then reinstall.
Make sure all of the electrical connections are tight by twisting the wires
together with pliers. If the smoke alarms are over ten years old you might
as well replace them as they have reached their rated life.

There's no such thing a digital battery. The marketing bull**** on the label
doesn't change a thing.
All alkaline batteries have a similar discharge curve.

Batteries that have a very sharp knee on the discharge curve are undesirable
as they die so fast that there is little warning.

Although it is true that *rechargeable* batteries shouldn't be used in
stand-by applications like smoke detectors, because of their rapid
self-discharge rate.
