KiddeWireless Smoke Detector, AA Battery Operated (Included), Ionization Sensor Wire-Free Interconnect Smoke Alarm

Very Good.

We had many of these installed in my home when we moved in our new house 10 years ago. They are designed to stop working after 10 years so we purchased them again. A few old ones are still working and I was able to connect them all effortlessly and connect them to old bars. I was so happy that they are the same size and model so i didn't need to install new bases. I also love that when 1 goes off, they all go off and that they are wireless. We've never had any issues with them connecting and we have a 3000+ sqft home.

My home is 12 years old and came with wired, interconnected smoke alarms. 5 of them. They had worn out and were malfunctioning so it was time to replace them. Initially I decided to go with a wired, interconnected system as a replacement, figuring it would be easy enough and I settled on 5 detectors by First Alert. Those detectors apparently didn't like the wiring in my home or something because they would randomly chirp three very loud chirps. Sometimes this would happen once per day, other times it would happen every few hours and since my home is not extremely large, it was nearly impossible to pinpoint which of the detectors was chirping unless the one directly over your head happened to be the one doing it. Mind you this was not a Low Battery chirp either, I won't get into it too much here but the customer service lady at First Alert was not helpful. She basically implied that there couldn't possibly be anything wrong with their product and it clearly must be my wiring (the exact same wiring that my previous 5 detectors had been hooked up to for 12 years without an issue). Figuring I would just eat the loss or hope to get some sort of refund from First Alert I decided to order brand new detectors -- again.Now, this time I went with this Kiddie wireless system because, hey, who needs wires? Right? The only reason I can see for having a wired system in my own home is if my home alarm was set up to automatically call the fire department if the alarm activate. I believe my system is capable of this, however whoever installed the home alarm system defeated this feature and I don't have any burning desire to see it re-activated. Ergo wireless sounded good to me.These Kiddie detectors arrived, and setup couldn't have been easier. They're wireless so before putting in the batteries you have to select a unique frequency for all of them so they can communicate with each other. To do this is easy, flip each over and select a random combination of ON or OFF on the small dip switches located on the back. I used a ball point pen to flip the tiny switches. There are 8 switches so just select some to be ON and some to be OFF and make sure each detector in your system is set the same. Once that's done, pop in the supplied AA batteries making sure to put them in the right way. Once you pop the last battery in, the detector will chirp softly once to let you know it's alive.After you have all the detectors powered up, press and hold one detector's test button and it will start to go off (it's loud, wear ear-plugs) and then it will signal all the others to go off too (if you have them all set properly). Mine worked flawlessly the first time.Since I was replacing an existing system, installation was a simple matter of loosening the mounting screws, removing the old First Alert plastic mounting plate from my ceiling, popping the new Kiddie mount up there, re-tightening the screws and twisting the detector on the mounting plate. No wires, no hassle, it was the easiest thing I had done all week.Hope this review helped you make up your mind. Now I'm off to go write a scathing review on the First Alert page, then I'm going to call them again to see if I can get some money back.

The media could not be loaded.  I have installed these in three different houses. They work great. If one detector goes off, it communicates with the next. If there is a fire in the garage, I am not going to sleep through it because the smoke detector in my bedroom on the other end of the house will also be sounding the alarm. Additionally, my security system has a device that listens for smoke and CO detectors so I will be alerted if I am away from home. Be safe!

Old Kidde wore out after 5 (?) years and, luckily, this one is the same model, so no need to install new bracket. We based our purchase on that, plus the first one was fine.

Bought a few these to replace the aging ones in my home. Of the units reviewed on multiple sites, this is the simplest, cleanest looking device that in a multi-unit configuration offers a good overall safety net. Having them interconnected means that while it may be nice to have a photoelectric detector, the advantage of whole house coverage leads me to think that it isn't as critical.To eliminate false alarms from other homes, setting the identity code is like a garage door security code - just flip the numbered "dip" switches in a random pattern before inserting the batteries as indicated on the unit (but use the same pattern for all of these devices).You will need to use the included mounting plate to install, but the opening is matched to most existing installs and is a matter of a minute or two two replace each one.Available option: they also make voice-sounders that are compatible with these as well as a flashing light.Warning: Don't try to get two wireless AC versions of these and then interconnect them by hardwire as well - they will set each other off. If you get an AC version with interconnectivity (like to a security system) just be sure to not hardwire interconnect any other units.See other reviews regarding compatibility with your existing wireless security system. You may have conflicts.

Every 10 years I replace all my fire alarm in my house and garage. Set the switch to act as one and good to go. Can't get easier.

There are two main types of sensors for smoke alarms available in the US: Ionization and photoelectric. I learned the difference after having this alarm for 2 years. I have one of these in the upstairs hallway and another in the kitchen downstairs.Ionization alarms are very sensitive to non visible smoke, but this also means if you have one in or near the kitchen it will set off so many false alarms when you use your oven / toaster / toaster oven / stove, that it will end in you constantly taking it down and moving it to another room when you want to cook. And subsequently forgetting to put it back up for a week. I recommend this smoke alarm for any room except the kitchen or just outside of the kitchen (or area where your furnace is). Get a photoelectric sensor for the kitchen / furnace rooms.Other than that thing to note this is a great alarm and the interconnected feature works well. I'll be looking for another Kidde interconnected photoelectric alarm to put up in my kitchen and hoping that the different sensors still work well together. Fingers crossed.
