Easy peasy
We had 7 of these that were 16 1/2 years in our house, (Out dated) The new alarms came with everything needed to retrofit the older alarms. Each one took 3-4 minutes to switch out. As of now all is great.

    JUNK ALARM!!! BEWARE!!!
    We have 6 of these hardwired in our home. They go off in the middle of the night scaring our family to death! My youngest son runs into our room crying because he thinks the house is on fire. We’ve replaced the batteries, even though they weren’t chirping. Then we’ve blown them out. Luckily, I found the one that was faulty because it started going off while it was in my hand. I just left it unplugged and took the battery out. Not a very safe thing to do, in case there’s a real fire! Also, It’s not a fun thing to do from 1:00 AM to 3:00 AM when I have to be at work at 5:00 AM. Very upset about this crap. It’s not the first time this has happened!

      The Kidde Firex Hardwired Smoke Detectors were very easy to install and wire. The great thing about them is the Ionization Sensor,and that they also have a 9-Volt Battery Backup in case you loose power. The price was perfect and because they came in a 4-Pack, I was able to replace 3 which I had in my home along with allowing me to add another in my laundry room. I find the KIDDE brand to be perfect for any home. Along with the smoke detector's I have also installed the KIDDE Carbon Monoxide / Smoke Detector combos in my kitchen and garage.

        Very nice detector and the price is reasonable. It also has a front end battery compartment, so you can replace the 9 Volt battery without pulling it off the ceiling. Great Buy!

        Do not work
        You need to make sure you test the interconnected feature after install!!! I installed these to replace ten year old expired kiddie models. As numerous other reviewers have noted, when one is set off, it’s supposed to sound all of the wired alarms in the house... but they don’t! This is concerning in the event of a fire when people are sleeping or with elderly or mobility impaired. I tried three different four pack boxes and mixed and matched and could not get any five alarms to all work together. Never more than two would sound with the primary, and my house is only 990sq ft, so it’s not a wire length issue, it’s a quality control issue. I switched to an older model number of the alarms with the front spring door. They worked instantly and only cost a few bucks more for a six pack then this did for a four pack. Actually cheaper per piece and now I’ll be having the electrician run wire out to my sleeping porch for the sixth one.
