I have 6 smoke detectors at home, and noticed that 4 of them had a
blinking green light. I thought the problem was battery, so I got some
brand new 9v batteries and replaced them on the 4 blinking ones.
The problem is, even after I replaced them, they keep blinking
(green), and sometimes do a soft beep.
- Does anyone know what a green blinking light means?
- How can I check the manufacturer? It doesn't say anything around it,
maybe I should open and check inside.
These smoke detectors are only 2 years old, they were put by the
builder, so I don't think I should replace them, right?
Thanks in advance,

The green blink is to let you know everything is "ok".
The soft beep (or 'chirp') is to let you know the battery is low.
If these are also wired for 110V power, the ones that you replaced the
battery in that are chirping might have the battery making poor
The blinking light will mean different things to different makes and models.
Separate the unit from its base, and where the jack attaches to the unit it
should have the make and model. Look it up on the net to find out what it
means. Generally there will be an audible sound, like a chirp every 45
seconds to let you know that the battery is low
Different brands act differently.
On ours, a blinking green and occasional chirp means it was triggered by
smoke, the smoke went away, but nobody has yet pushed the reset button
on the alarm. (Useful if you come home and see it blinking -- some time
while you were gone, there was enough smoke to trigger the smoke
detector, even if it's not still going.)

Are you sure the builder didn't leave the owners manuals around
somewhere? I'm the second owner, and I don't think I have the manaual
for my smoke alarm, but I do have the manual for the bathroom fan, the
range hood, the water heater that was first in, the furnace, the AC,
plus all the appliances the first owner bought.
Maybe your manual is somehwere in that stack.
Hi all, Thanks for your answers.
I just replaced the batteries today, and about half hour after I did
that they stopped making the noise.
But as soon as I get home I will make sure to check the contact, to
check if thay are making poor contact (as per Dave).
I will also follow RBM's advice and check the maker/model and look it
up on the net to see what they say.
J., I think you are right, because the alarm was triggered 1 month
ago, and only after that I have been noticing the blinking. However I
don't see any Reset Button, there are 2 buttons: "Hush", and "Push and
Hold to Test".
Mm, I did check all the manuals from the house appliances, sprinkler
timer, AC unit, refrigerator, range, microwave, etc. I keep them in a
specific folder, so when I sell the house I can pass that on. But the
Smoke Detector wasn't there. :(
Again, thanks to all the answers, I will keep you guys posted.

Thank you, Jonathan! We were having the same problem. Changing the battery
didn't help, but holding down the test/reset button for 5 seconds fixed the
problem. It was LOUD, but it worked! Thanks

After a storm last night, my smoke alarms went off (beeped 3 times with very
