Answer: 
The beeping is caused by a weak or faulty 9V battery. Replace the battery and the beeping should stop. If it continues to beep, even with a new battery, the unit is faulty. You should replace the unit. If it is a new unit, take it back to HD and they will give you a replacement.

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: 
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: 
No, it is only fire and smoke detection. There is a separate unit which will state that it also senses Carbon Monoxide, states it on the box, and they typically are more expensive.

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.

Answer: 
If the alarm is triggered by smoke or fire, it will go off. If the fire alarms are wired into a series, where one is connected to another, it would also trigger the other alarms. Depending on your set up, it could also send an alert code through you security system, to the Fire/Rescue or whomever monitors the security system.

Answer: 
Usually if one goes off some of the others then will also but not all by design. I will hazard a guess on how and it is probably because they are hard wired to your AC electric and when one alarm is triggered the ones that go off do so by sensing the ampere draw or an electrical disconnect off and on which triggers something on the circuit sending that triggering command down the AC load wire

Answer: 
Yes it will active the other alarms in your home as long as you have the correct wiring in place. Typically smoke detectors are a three wire system. Black wire is power hot, white wire is power nertual with bare ground. Additionally you should have a red signal wire. This is the wire that interconnects all your defectors and will allow all of them to go into alarm once one does.

Answer: 
Mine have lasted over 10 years, but that is when I started replacing them. They would short out or drain a new battery in 1 day. If you push the test button and it squawks, and the light is green, then it should be OK. So use 10 years as a rule of thumb for replacement.

Rated 4.2 out of 5 by 201 reviewers.
Rated 5.0 out of 5.0 by Hard wired, Interconnnected Smoke Alaem I Replaced a faulty smoke detector with this model. It was easy and quick to replace the faulty smoke detector with this new model. The installation instructions were understandable and easy to follow. The replacement smoke detector has been working for the last two months with no problems. July 26, 2016
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 Easy to install, good to be safe The Hardwired 120-Volt Inter-Connectable Smoke Alarms with Battery Backup installed without issue and worked with the other long ago installed alarms. Tested in both directions, these new alarms were MUCH louder. Good thing I guess! I bought and installed two alarms. October 11, 2016
Rated 1.0 out of 5.0 by RETURNED PRODUCT UNUSED Kiddee stated this was a matching replacement for my old Firex alarm. Just plug it in and screw the unit to the installed base. The plugs didn't match, the base didn't match the unit and the cover to the backup battery was stuck in OPEN position once I opened it, not knowing there was a battery already installed. Returned product and called an electrician. October 18, 2016

Rated 5.0 out of 5.0 by great Value All 6 fire detectors in our recently purchased house were beyond their 10 year life expectancy and had to be replaced. These replacement units were exactly what was needed and the wiring harness provided was an easy install. Order came quickly and I can now sleep in peace knowing the fire detectors are working properly. On line ordering was a breeze. I encourage you to check your fire detectors and replace them immediately if they are expired. There typically is an expiration date on the back or a manufacturing date. If older than 10 years, be safe and replace them. September 8, 2016
