Two first alert smoke detectors go off for no reason. All are on 110 with good batteries. Have had these for approx. 12 years with no problems until now when 2 of the 7 have gone off many times in the last...

There may be dust built up in the sensing chamber. This can cause alarms to go off for no reason. Try vacuuming the alarm off particularly around the sensor if the cover is removable. These alarms should be replaced however, as they are more than 10 years old.

My alarm chirps every 30 seconds and i have removed the battery

This is a really odd situation. In that you have removed the battery and it still chirps, as if the battery was still installed, but was getting weak. So odd, that I took a look at the Owners Manual online to see what it had to say about it.

According to the Owners Manual this is a totally battery operated unit. When I read your problem/question, I thought it might also be a hardwired unit with a battery backup, in case of a power outage. But, that's not the case. I also learned that this detector can be used with a remote control.

In any event, the only thing I can think of is that the ionization feature may store some residual power, which causes the detector to chirp even if the battery is removed. I that's the case, it should weaken over time. But, in the meantime, the chirping is annoying.

In the meantime try silencing the alarm by Pressing the Test/Silence button on the alarm cover for at least 3-5 seconds. Hopefully, that will quiet it.

Also, the detector may need cleaning, as dust, dirt and lint accumulations can block the sensors.

Juts in case you've misplaced your Owners Manual, I have included a downloadable link, that you can print for future reference.

Hope this helps you.

My First Alert Carbon Monoxide Alarm has failed

If the carbon monoxide detector chirps, the battery may be dead. New batteries can be defective. Check if the light is yellow when the alarm is chirping, it means the battery is low, replace with a new battery.

If after replacing the battery the alarm is still beeping, the smoke alarm is bad and needs to be replaced. Hope this answers your question. Best of luck!

Alarm system is not activated we just bought the house and it keeps beeping off and on how do we stop it?

I would try and get the owners manual for the alarm system and see what it says about the beeping. It could be that it is just telling you it needs a new battery installed, something like the battery operated smoke detectors do when the battery is low. There are so many alarm systems out there that it is hard to tell what could be causing the beeping. It could have been configured with a audible alert that when the system is tripped by any motion it beeps when off. It is really hard to say without the manual. You can usually find the manuals on line at the manufacturers website. Good Luck, RAC
