I have a condo and it has the original smoke detectors, FireX. Probably abo
ut 20 years old. they don't take batteries, that's probably why they have n
ot received much attention. The are hardwired to AC with a signal wire to t
he other 2 detectors. Don't believe they are on a separate circuit, should
they be ?
Should they be replaced ?
Usually, the max recommended life is 10 years. Here's a link that says that
in the middle of Page 2 of the document.
If you are in a condo, you may want to check with the condo association to
find out if your smoke alarms are interconnected with alarms in other units
in the building or an outside alarm if they go off.
You may be able to switch them with detectors that also have a battery
backup -- not sure.
I don't think they are interconnected with other units, I have tested years before the and the neighbors have never said anything about it.
I know that we don't have any type of notification system with the authorities or a blinker on the outside of the unit.
I was just inquiring about the life of the sensor and/or unit. They are the original equipment.

You could light a fire under one of them and see if the alarm goes off.
You wouldn't need a big fire, even a wooden match would do I think even
a wooden match that had been extinguished would make enough smoke.
The problem is that you woudn't know if it was as sensitive as it should
be. I guess you should have done this when you first moved in, so
you'd have a standard to compare with.

I don't see why it would be any problem getting replacements for
AC interconnected ones. Standard install is normal AC wiring with
one additional wire that runs between units. Independent ones don't
provide the same safety. If you have a large house, are a sound sleeper,
one going off in the basement at the far end of the house may not be
enough to wake you up in the second floor bedroom, etc.
Good point but I never saw an expiration date on my very old detectors
and my wife was constantly testing them by not venting the oven enough
We replaced all of them last year when she was cooking, an alarm went
off and drove us nuts trying to figure where when it turned out to be
the CO detector telling us it was dying.
We replaced with more expensive but long battery life detectors maybe
good for 10 years before sending at annoying warnings.
I bought a new smoke detector, and put the old
one on a high shelf. Couple months later, the
detector chirped. Took me a long time to find
the old one (out of sight, battery going weak)
as I'd forgot I put it on the shelf.
My Monoxide detector takes batteries three times
a year, the two AA cells go dead rapidly. The smokes
take 9 volt cell, I try to remember to replace every
time I change the clocks. Tempted to get the new
lithium cells, good for several years.

Mine were in first and 2nd floor hallways near stairs and when one would
start chirping it took a while to figure which one. Now with these long
lasting batteries, I should not hear anything for 10 years.

I have that problem too. The chirp is so short and far apart that it can
be hard to figure out which one. The part I don't get is these are AC plus
battery, yet they start the chirping within about a year. One would think
that a battery that's only there for backup would last many years, basically
the shelf life minus whatever usage occurs during power outages, which here
isn't much. The other part that's a pain is one of them is up high where
it can't be reached with a stool or typical small ladder.
I'm at the age where I'll pay an extra buck or two to avoid an annoyance
like this. Older folks are more at risk from a fall than from a fire.
Then a lot of devices that need batteries changed every year or so, e.g.
a thermostat, are not clearly marked on how to access the battery.
I bought Smoke and CO detectors in 2006. The smoke detector (First Alert
with both ionization and photoelectric sensors) has instructions to
replace it after 10 years.
AS to the CO detector (NightHawk), it failed and had to be replaced in
2013. The new one has no such message.
I think if he unplugs one unit and brings it to a Home Depot or Lowes or ACE
Hardware etc., they will have compatible units that can be used for
replacements -- and probably they will be hardwired units with a battery
backup in case of power failure. That's what I did with a 110-volt AC
hardwired interconnected alarm system that I have.

Unfortunately, I think code requires that they be battery backed up now.
I'd rather just have the AC ones and not have to deal with screwing around
every year with changing batteries. Yeah, the battery backup provides a
little extra safety, but not worth it to me.
Another curious thing I don't understand. The AC plus battery back up ones
I've had experience with, the batteries have to be replaced about once a
year, they start beeping. What's up with that? You would think AC would
power the thing, with the battery only being called on when the AC goes
out. But if that were the case, then the batteries should last a few years.
Any idea what's up with that? Any experience?

Given the cost we replace and trash (no gifting) @ 5 years.
Went back to the condo and pushed the test button, Nothing.
Went to Menards and bought 4 new Kidde replacements.
I will try to get them in this weekend.
After replacement I will test and check with the neighbors to see if there units alert and post a follow up.
