I bought the Kidde/Firex brand for my first house, same model. I have never had an issue with a defective unit. I had to remove the old harness and install the new one as the quick connect wasn't compatible. The old Kidde/Firex units are 8 years old and the connector is slightly different. I replaced 5 units in an hour or so. I replaced them because I wanted the combination smoke/CO - they weren't defective.

Rated 5.0 out of 5.0 by traut Easy to install - All 3 worked perfect right out of box
My old detectors had a different wiring harness - It took all of 10 minutes per unit to rewire and complete installation. Entire project was done in less then 1 hr and all 3 levels of the house are interconnected and alarms goes off on all 3 levels when testing. Very satisfied with the purchase.

Rated 5.0 out of 5.0 by RSMguy who would've thought I would get excited about smoke alarms!!
purchase the 3 pack combo smoke detector and co2 detector. I bought this because I didn't want to buy a separate smoke detector and a CO2 detector. Too much clutter on the walls. The combo did the job. Very easy to install and operate. Plug and play installation. 3 wires and you're done. I installed all 3 in my house in less than 30 mins. Looks great! Love the voice feature. It was a bit pricey but you get what you pay for. Overall good purchase for a combo smoke/CO2 detector.

Replaced existing Firex Smoke (only) Detector with Firex Smoke & Carbon Monoxide Combination Detector to bring home up to existing Arizona fire code. Replacement was easy as it fit the existing mounting bracket and the plug in connector for the 120 Volt supply and communication to the other 10 detectors was an exact match.

Rated 5.0 out of 5.0 by NeighborDave2016 Perfect for my need. straight forward installation
Three interconnected units installed in my log cabin. Installation was easy using 14-2 wire to connect to the circuit breaker. 14-3 wire between each alarm. Very easy installation. You need to purchase screws to attach the alarm to the ceiling box.

Rated 5.0 out of 5.0 by Jeff This product was the solution I needed!
I added on to my house and had to bring all the smoke detectors up to current code. That meant installing wire, boxes, and new detectors. Where I live I needed interconnected detectors. I was replacing dual (ion/photo) battery operated alarms which I had installed several years ago and was happy to find these that included photoelectric, carbon monoxide, voice alert, and battery backup. Single units with all those features can be expensive when installing several at once - so finding a 3-pack that saved me about 1/3 on cost helped a lot (I didn't have to settle for a lesser product). Installation of the detectors was a breaze and they've been working great. Thanks Home Depot!

Rated 5.0 out of 5.0 by Mayday Just what I needed
I had to add a carbon monoxide alarm to our upstairs area so i decided to go with this alarm. Since I was replacing this to an existing alarm area the instillation took all of 5 minutes. The big revelation was that our smoke alarms were all over 10 years old which is beyond the recommended life of smoke alarms. I decided to place a second order and replaced all the alarms in the house with the smoke detectors needed. I believe you'll only need one CO unit per floor in your house, All the other units can be the basic smoke detectors. The installation was simple and the products seem to be very good quality. It's also nice to get rid of those dingy yellow ones and replace them with these new white units.
Replacing older alarms was not something I realized was necessary. Check the age of your alarms and if they're older than 10 years I'd recommend replacing with this product.

Don't take chances: If any one of a group of interconnected alarm units complains of not working properly, replace all of them. The three pack saves a little money and automatically ensures that the alarm units are designed to work with one another.
Very likely you'll have to replace mounting rings and wiring harnesses to accommodate the new alarm units, so be sure to check that the harnesses and rings included with the kit meet your home's requirements. Save yourself hassle by taking one of your old alarm units, its harness and ring to the store for comparison before you buy.
Once you have everything connected, test exhaustively by pushing an alarm unit's test button and then running around to verify that all the others properly scream about it. Repeat this by triggering each unit. Also test operation with mains power disconnected, thus depending upon each unit's 9V battery. Yes, testing is tedious, but it could save a life.
