I like these better since the battery door is on the front and not the back like my old ones. I was able to use the same harness from my old ones. I just had to put up the new mounting plate. All in all, the installation was easy, and they seem to be working OK.

These 6 Kidde smoke alarms were used to replace 6 Kidde alarms that were 12 years old. Two years beyond the manufacturer suggested replace date. Since the original alarms had the same plug from house to unit, the replacements were a snap. The base plate R/R was the most time consuming. The kitchen unit has already been tested once, and the system alarms (whole house) all sounded. Being a designer for Mack Trucks, it's great when R/R goes easily, and replacement units work as designed. Total process R/R 2hours, with time spent cleaning area at ceiling around old smoke alarms. Thank you Kidde design team!

We used these to replace all of our smoke detectors in our home because one kept chirping plus they were about nine and half years old. So there is not more chirping in our household. It took our handy man one hour to replace all six of the smoke detectors. I'm one happy camper right now. I purchased this brand because our old ones were this brand.

Rated 4 out of 5 by from Great but came with low useless batteries These are great! Only problem was the batteries that were included were already in the battery compartment of the alarms when packaged so the batteries were drained and low which caused the alarms to chirp and they started chirping in the middle of the night the first night after we installed the alarms and we had to replace all the batteries.

Rated 5 out of 5 by from Went up easily Had my other expired smoke detectors replaced. ( Did you know they expire after 10 years?? Who knew??) Watched them being put it, went in reasonably easily. These feel more solid than the old ones. Wired and 10 year batteries i had put in them, hopefully I'm set for a while, I hate 3am wake up calls from chirping batteries!!!

Because these were replacing 10 year old smoke detectors (that used older style plugs), I had to replace the wire plug on each detector but even with that, it only took me 35-40 minutes to rewire, re-mount the detector mount and hang all 6 smoke detectors.

Rated 5 out of 5 by from Replaced old smoke detectors and am happy Bought pack of 6 to replace old smoke detectors (same models). All I had to do was unplug the old units and plug in the new. No wiring work needed. 'Twas simple with no problems. So far, work great with batteries that came with the new detectors. Definitely recommend for replacing same models.

Rated 5 out of 5 by from Easy Upgrade My 20 year old smoke detectors were failing and I needed a solution. I had Firex detectors, but the power plug was different on the new detectors. Luckily the new connectors and pigtails came with the new detectors. Quick work. All replaced and random beeping is gone!
