Kidde Smoke & Carbon Monoxide Detector, Hardwired Interconnect, Combination Smoke & CO Alarm with Battery Backup, Voice Alerts

Perfect replacements, didn't even have to change the bases.

Easy to install, works great!

In marker, we have latest models available which are wireless, bluetooth supported, etc. with new features but those are not good quality made and detection of fire and CO2 is also not better compared to old model. Hence, old model are still does the very god job without much hassle and hence these are expensive as well.Its been 2-3 months and this product is doing good job so far.

Great bulk pricing

Our power went off in the neighborhood and then the fire alarm which is hardwired started saying over and over warning Carbon Monoxide and it would not stop. I pulled the batteries and it stopped. We have 5 of them and only two of them were doing it. When the power came back on it beep for no battery and I installed the battery and it did not say Carbon Monoxide. So my question is every time our power goes off is the alarm going to start saying Warning Carbon Monoxide? I sent an email to Kidde and have not got a response.

So far it works great and was easy to install.

Purchase this to replace the detector in household, arrived on time and easy to install

It's an excellent smoke and CO2 detector, but Kidde has discontinued this model and changed the electric connector, so if you already have this model and hope to just twist off the old one and twist on the new one, you're out of luck. If you are not handy with electrical work, get an electrician to wire the new model. My local electrician charges $150 standard trip charge, plus $100 per hour labor, minimum one hour. $250 seemed a little steep for this, but it didn't vary much after talking to several electricians. It was much more prudent to purchase the latest model and a package of Spade Quick Disconnect Wire Connectors at https://www.amazon.com/Disconnect-Connectors-Terminal-22-18AWG-18-14AWG/dp/B09HB3YTKG/ref=sr_1_11?crid=J8S0A5MT8VVG&dib=eyJ2IjoiMSJ9.je5FH5B71oN73_NCtPPK6czxhjhzVo99eyBARjO8jnjv-baGkMx1oCoPgZd8DrjIjPSHNRfW4ts4GKQqPgAi4KuLXMjGB_Nio-JuweNogzAcfDCubiMfk-D7I7ld0v1ikqywMuA6ZMIkIt54ffYjGFPcroSRVDDSFQ3J-Rq1RJaowbYjo7SuLm-q51m9PUGqNmnr_kAqJz7DrTNTMoHZ2ZSFgvWPiWjtcCTKpFsU6mE.caAMtNEefwI7ZiAQKnXOTMjykONqr1OI-Dvvjp6Wo-o&dib_tag=se&keywords=electrical+wire+quick+disconnects&qid=1714721096&sprefix=electrical+disconnects%2Caps%2C139&sr=8-11Put on the new back plate, put two male disconnects on the bare wire in the electrical box and two females on the connecting harness that comes with the new model connector. It's, at most, an irritating 30 minute job, but the disconnects are 7-bucks, not $250.00.
