Answer: 
Three reason for it to be beeping.
1) Low or bad battery.
2) No A/C power
3) Smoke detector is bad and needs to be replaced.
If it is bad this is a very simple replacement. Turn the detector counter clockwise. You will see the wiring that snaps into the back of the detector. Simply un snap the wiring harness from the detector. Make sure you buy the same brand (under $15.00!at HD). Once you have the Read More

Once you have the detector out of the box snap the harness into the new detector, gentle fold the wires back into the box and screw the new detector vlockwise onto the base. There are no exposed parts so there should be no electrical hazards. Best of luck. Read Less

To temporarily stop the BEEPING, Removing Battery is not enough! It must ALSO be UNPLUGGED.
It is SAFEST to turn off the electrical circuit at the breaker box to make its green light go off.

Answer: 
Should of mentioned in my comment that before replacing the unit, you should have read the owners manual on maintenance of the unit first. Also check the manufacturing date on the bottom of the unit. Should be replaced every ten years. See NFPA recommendations

Answer: 
The unit is bad and needs replacing, or the hard wiring lost its connection, either way it is a good idea to replace the unit. Always replace with all new parts and wiring connectors.

Answer: 
It is possible that one of the other units in line with the one beeping, is in need of a new battery, or possibly the battery you replaced is not a good battery. Also, check to be sure that you have installed the battery in the correct position in the detector.

Answer: 
You would have to remove the battery backup and then shut off the circuit in the service panel if it is a "dedicated" circuit which I believe it should be. That means there should a breaker switch that controls only the alarms. I believe battery only units are better and one in each room. Many local fire departments give them away.

Answer: 
Once installed these are not designed to be turned on and off. The battery is merely a back up power connection. So you can either disconnect the wires from the back of the unit, or turn off at the fuse box the particular fuse which powers this unit. The fuse box will probably turn off other electrical outlets which use this set of wiring.

The light is green but it blinks red every 30 seconds. Bought it at Home Depot in Spring Hill on Monday. It had been returned apparently, because the box was torn apart. It was the only one on the shelf, so, foolishly, we took it.

Answer: 
This is probably caused by a weak battery. Replace the battery, and if that doesn't work, there may be a short on the circuit board which means you should return it to HD for a new one or a credit.

Answer: 
No. This unit is for smoke only. Look for listings that say both smoke and CO, if you want Both. Look for those with CO only if you only want Carbon monoxide alarm. The manufacturer does make combination models; however this model is for smoke only.

Rated 4.2 out of 5 by 176 reviewers.
Rated 4.0 out of 5.0 by I hope I'll never need this alarm to go off! Easy to install. I like that it's "hard-wired" to electricity, and has a backup battery (9V) that looks like is easy to change, and easily accessible without having to dismount the alarm (battery was included, which is nice). June 28, 2016
Rated 5.0 out of 5.0 by smoke detector Replaced 16 year old firex detectors in house. Easy install works as it should July 12, 2016
Rated 5.0 out of 5.0 by Worked perfectly to replace old unit Unit was a direct replacement for a 6 year smoke alarm that went bad. Simply unscrewed old unit from base, unplugged power from old unit, plugged powe into new unit and screwed new unit into old base. Very easy swap out with no tool required (except ladder) June 21, 2016
Rated 5.0 out of 5.0 by FireX 120V w/ Battery Backup I noticed the manufacturer date on my existing FireX smoke detectors was June, 2000 and they were now 16 years old, another words, it's time to replace them. Code requires 120V and linked detectors in the bedrooms. That is why I selected this particular model. I removed the old units and their bases. The bases are different but it's just a matter of loosening the 2 screws and replacing the base. The wiring "connector", not the wiring, is different so I did need to rewire it in the box. That's when I found the previous owner never hooked up the alarm link wiring. Replacing the alarms was worth the discovery so I could correct it. The directions also give ambient operating temperature ranges. Since this is my cottage, I set the temp at 50 when I'm not there in the winter and close one room door so it doesn't get heat. Turns out temps below 40 drain the battery. Another lesson learned with good instructions. I also like the battery access on the outside of the unit. The old was inside. June 14, 2016
Rated 5.0 out of 5.0 by works as intended This is your basic smoke detector, nothing fancy just a good basic unit. June 14, 2016
Rated 5.0 out of 5.0 by Easy To Install Replacement Smoke Detector After replacing several batteries in my 13 yr old in just 2 days I decided it was broken. Had to be a 120V wired unit since it is part of a series of detectors. This FireX unit by Kidde was easy to install although I had to turn off the power at the fuse box first since I had to handle the wires in the wall. There was no plug interface so I couldn't take advantage of the various interface plug options that Kidde provided. It took only 10 min. for the whole switch out and it comes with a 9v battery. Works great, looks good, and Home Depot had the best price and in stock! April 29, 2016
