KiddeHardwired Smoke & Carbon Monoxide Detector, AA Battery Backup Smoke Alarm, Interconnectable, LED Warning Light Indicators, 2 Pack

When we purchased our home it did no have any gas appliances so did not have any carbon monoxide detectors installed in the home. Fast forward to the next winter we upgraded our HVAC system to a gas furnace so wanted to ensure our home and family was protected from the dangers of potential gas leaks.When choosing an detector I wanted to make sure that it was hard wired in with our entire house as well as have a detector that had a smoke detector as well. After researching different brands I found that I liked the reviews on the Kidde Hardwired Smoke & Carbon Monoxide Detector the best as it also had the AA battery backup.Coming from public safety a backup is always preferred as living in more rural areas seconds and minutes count to get out and get to safety.After turning off the breaker and testing to make sure power was off to the detector circuit, Installation was a breeze with the provided instructions and only took a few minutes to install once the old detector was disconnected. I made sure that the battery was also good before connecting it to the power as well. Once the new Kidde Hardwired Smoke & Carbon Monoxide Detector's were all installed I made my way through the house and tested each one. If your detectors are all connected I love that when one is alerting, they all alert to warn the entire house of the danger.After using for a few months now I will definitely purchase Kidde detectors in the future if needed. The value of safety is priceless but the cost of the detectors is well worth the listing.Be sure to always change your detector batteries once a year!!

I replaced (2) combo detectors in our house - each about 10 years old. They still chirped even with new batteries. While it was the same brand, I still needed to replace the pigtail with the one supplied with these. No biggie - they work fine.

I replaced my existing old smoke detectors with these. Installing the wire harness and the bracket was super easy. The wires are color coded - Black (Power), White (Neutral) & Red (Interconnect). The alarm easily secures into the circular bracket. On the plus side, I liked the fact that the detector uses 2 AA Batteries for standby power instead of the typical 9V batteries found in typical smoke alarms. The only minor drawback, for me, is that battery compartment is located on the backside of the unit. This means that one will need to unscrew / remove the unit from its base in order to replace the batteries. Although, I suppose it's not really that big of a big deal. I mixed these dual sensor unit with the same brand standard smoke detector and found that the interconnectivity works.

Only allowed 30 days. Broke on day 32. 2 Fire trucks later-The fire department says it’s defective. Kidde wants to troubleshoot. This is a potentially life saving device. Our $50.00 could have just as well been put in the shredder. Awful product!UPDATE: The seller is replacing our unit. The customer service was well done. Changed rating from 1 ⭐️ to a possible 4 ⭐️ ⭐️ ⭐️ ⭐️

Luckily I haven’t seen them in action yet.

The house is a bit more than 8 years old and has a bunch of these detectors. They still function perfectly, but someone thought it good business and got the law changed to force replacement of these detectors by starting a never ending beep. The choice is to replace a still working unit with another one, or toss it and go without. The plug did not match, so I had to wire the new one into the wire nuts, seems like an unnecessary step too. The new alarm now works without beeping. Reminds me of the seat belts in 1974 cars that prevented you from starting the car, even to go down your private drive to the mailbox, easily cured with a bit of rewiring under the seat. I suspect many will go without a smoke detector because of this 8 year replacement "feature".

Nice quality product. Had to replace the original after 10 years. Only thing is that the plug is slightly different than the original, so we needed to call an electrician to make the adjustment. Was an easy fix since everything is included in the box. Sound will surely wake you up if it goes off in the middle of the night. Great value for the money.

easy to install - seems to work - meets my local building codes - but expensive!
