I had the same problem.  This worked.  Turn off all electric power to all smoke detectors, then remove all batteries.  Wait about 15 minutes, or until they stop chirping on their own.  Then replace the batteries, replug in the electric, and then flip the circuit breaker to send the power back to the detectors.  After a very sleepless night, it is finally quiet in my house.

Additional Info from Firex:

 

The beeping may be an indication that the batteries need to be replaced. On units with an LED, the red LED will blink approximately 4 times a minute. Replace with a fresh 9-volt battery alkaline battery of a quality brand. Do not use any type of rechargeable battery.



If the unit continues to beep even after replaceing the battery, it may need to be reset .



If unit is an AC unit with a battery backup. Remove the smoke detector from the mounting bracket and disconnect the power, or turn off the power to the smoke detector at the breaker. Remove the battery. Press and hold the test button for at least 20 seconds. The unit may chirp or or alarm for a few seconds before going silent. Reconnect the power and reinstall the battery. The unit will chirp once when the power is restored and should not chirp afterwards.



If the unit is a battery only unit, remove the battery. Press and hold the test button for at least 20 seconds. The unit may chirp or alarm for a few seconds before going silent. Reinstall the battery. The unit will chirp when the battery is first connected but should not chirp afterwards.





Try cleaning your detectors if the above solutions do not work. Remove them from the wall or ceiling and hold the unit on its side. There is a gap between the front cover and the back plate. Take a vacuum cleaner with a crevice tool or a can of compressed air and clean all around the gap area. Pay most attention to the sensor. The sensor is in the gap area and looks like a small tin can with slots in it. This needs to be thoroughly cleaned since there is dust or debris caught in the sensor. This should fix your problem.

Hello,



I have the same model detectors in my home, and  I had the same problem with one of them.(Repetative chirping... No manuals were left by the contractor... no manual available from the manufacturer online...).   I tried the "reboot" procedure as described above, and IT WORKED!  Thank you, thank you.

Try Disconnecting All Detectors. also remove the batteries then press and hold  the test button 2 remove all residual power in each of the detectors. then replace batteries and reconnect and this should take care of da chirping sound that u hear every 30 seconds

If you clean them with an air can the chirping will stop.  It was the only thing that worked for me.  Vaccuum them then use the air can.

Dave - thanks for posting this.  I have these same crazy alarms in our house and because you posted this answer (essentially disconnect and clear it by pressing 20 seconds) I have had my sanity returned.  I found this posting a few months ago and now its on my favorites... thanks again.

I had the same experience.  I disconnected the smark alarm from the plug and replaced the battery with a lithium 9V.  Initially the red light flashed every 8 seconds but eventually reset itself and would flash once every 40 seconds.  What was maddening was that when the detector reset it would cherp twice which made me think I had not fixed the problem so I would repeat the whole sequence.  Eventually I had all the detectors reinstalled and would hear the double cherp but couldn't decide which detector caused it and decided to wait a while.  The cherping did not return.

I just want to thank you for your responses.  You have been so helpful.  I think you saved my sanity.  I love you and I don't even know you.  Hallelujah!  The chirping has fled the scene.  Jah Bless!

Same thing happened to me. One of the connectors was loose. Problem fixed. My girlfriend is happy.

A defective (not dead) battery might be the cause.  

I suffered three days of torment and tried all the tricks suggested.  Then I found that one of the new Duracell batteries I had installed was defective.  I should have noticed when I installed it that it was bulging out at the bottom.  I replaced it with a good battery and that solved the problem.  I am sure this is rare, but I give a black mark to Duracell quality control.

I had a similar problem with (wha I thought was a 120-1182), but when I went to he FireX website(now run by Kidde), I found I was mis-reading the model number.  The model I really had was an "FADC".  The Kidde website state;



"If you look at the back of the alarm, you will see where the text is split into two columns, with text on the left and text on the right.  The model is the text on the top of the left hand column after "Model." The date of manufacturing is stamped on the back of the alarm in blue or black ink and it will give you the year, then the month, and then the day."



The manual I donwloaded from the Kidde website states the following for the FireX FADC smoke alarm (if it is beeping about once minute);



1) Turn off power and replace battery.  (See "Battery Replacement" i the "MAINTENANCE AN CLEANING" section.)

2) On item 4718 only.  Be sure red LED is extinguished after replacing battery.



The Kidde website is www.kidde.com

FireX 120-1182  Constant chirping.  Internet search provided suggestions plus one I added that worked for me:  take alarm off the wall/ceiling, battery out and hold down test button til the bloody thing quits making any noise, use pencil eraser on battery contact points to clean, vacuum unit thoroughly including edges particularly where little tin can with slots can be seen, use small screwdriver to bend battery contacts out (a bit closer toward battery contacts) to insure good contact, reinsert battery but be very sure to push down on the battery after inserted as it rests on a spring loaded plate that must be pushed down (!)to insure good contact, plug back in hardwire and reinstall in ceiling/wall.  Should behave itself now.

I've replaced all batteries, reset the units, reset the breaker - still chirping. I can't get it to Stop!!  What am I missing?

Mine had a loose battery connection. I had to open it up and reinsert the connector. Be careful opening the smoke alarm the metal disk will come loose. The shiny side faces toward the outside of the unit. I had to verify this on another unit in the house. Put the battery back in and the chirp is gone. The connector must have come loose when I replaced the battery.

Persistent chirping. Per manual, Turned off power for 15 minutes, put in new battery, still chirped. Then I used a flat head screwdriver underneath the plastic flange of the wired plug to pop the plug loose, then had to pull plug out the rest of the way by hand. (I'm posting because it was hard for me to figure out how to unplug the wired plug.) Removed the battery, depressed the reset button until there was silence, waited 15 minutes, then put in a different new battery (chirped once) and plugged it back in. This worked.

Thank you so much for this advice,  We had two alarms on opposite sides of a wall, each one beeping in turn.  We had to perform the reset procedure once on each, then on both together at the same time, get stop the chirping.

Addition: Please make sure you plug the unit into the electricity BEFORE you put the battery back in; otherwise, it will keep chirping.

After a power flux at the house, we had the same problem with intermittent chirping and the red LED on the smoke alarm blinking every few seconds to every 40 seconds or so, depending on the individual alarm. I switched off the circuit breaker, verified the green LED was out, removed the battery from each unit, pressed the test button for 20 seconds on each unit to fully discharge any residual power, waited 15 minutes, switched on the circuit breaker, verified the green LED was on for each unit, and then reinstalled the 9v batteries. Problem solved! My guess is the power flux played havoc with the microprocessors on some of the units, and they needed to be fully powered down and restarted before they would work properly.
