Features:

  • Wireless technology uses radio frequency to transmit and receive messages
  • Battery power enables homeowners to install interconnected alarms without rewiring
  • Smart touch button quickly and temporarily silences nuisance alarms
  • Wireless alarm can be installed in a detached workshop or shed
  • Kidde wireless smoke alarms meet UL requirements. Interconnects Up to 24 devices ( of which 18 can be initiating). With 18 initiating devices (smoke, heat, CO, etc.) interconnected, it is still possible to interconnect 6 strobe lights and or relay modules
The deciding factor for me was that these smoke detectors all communicate with one another in case one goes off they all go off.

I love these smoke detectors that I purchased for my new home for one reason alone that was the deciding factor in my buying these for I am extremely hard of hearing and live alone and normally at home I don't wear my hearing aids but because of that I don't hear much of anything and the feature that these smoke detectors have that made me want to buy them especially because of my severe hearing loss is that they communicate with each other so if smoke sets off one smoke detector that smoke detector will communicate with all of the other smoke detectors that you have of the same model and cause them all to start sounding the alarm so I have purchased over one dozen of these smoke detectors and have put them and all the strategic places throughout my house like in the worship and dryer area and near the boiler water heater that uses natural gas and outside in my backyard in my tool shed so I could be in my bedroom with my door closed sleeping and if one of the smoke detectors at the far other end of the house goes off then they will all start going off including the one in my bedroom letting me know that there is a fire someplace otherwise if the smoke detector in the washer and dryer area that is in the garage goes off because of a fire in the garage I would never hear it and the smoke detector in my bedroom with my direct close would not go off until the entire house was already engulfed in fire and smoke so this particular model gives you an early warning that gives you much more crucial time to escape or to put out a fire before it gets out of control.

Nice safety feature having them interconnected.

I originally bought a pair of these from a big box hardware store fro about 40 bucks each. Welp, after 10 or so years one of them started chirping, so I changed the batteries: it still chriped. I put on my glasses and read the back of it and it says it will start chirping after 10 years to let you know to replace the unit. I guess I forgot about that over the years! LOL So, assuming the second unit will soon start to beep, I went ahead and ordered replacements, but at less that $26 each, i went ahead and ordered a third to put into an isolated utility room. Afterall, these units are wirelessly interconnected, so I figured a room that has a closed door needed one because if a fire starts in there, I want an early warning!!! These little guys are LOUD and with the wireless interconnect that ALL go off. Since still have one of the original one that has not started to beep (yet), I set the dip switch codes on the new ones to match the old one. Yes, there are dip switches on each one that need to be set to something unique "just in case" you have neighbors with them and you don't want your units going off when they test theirs (or vice-versa). Do I recommend? Well, wireless interconnected smoke alarms that are loud make sense to me, so YES, I do recommend them!

PLEASE read before installing, and save some time!

Wish I had read some reviews first to understand how simple this was, and which product(s) to purchase. Could have saved me some heartache. First, if you are ADDING to an EXISTING, WIRED smoke detector system, you MUST replace at least one of the existing wired alarms with the Kidde RF-SM-AC Hardwire Wireless Interconnect Smoke Alarm with Battery Backup for them to interconnect [...]. Replacing this was easy ... using the converters that come with the detector; it literally took 10 minutes. Match the existing male plug to whichever of the provided converters fits, attach that to the new Kidde, install the new base plate using the existing holes, and attach the new Kidde Overall, the labor for this entire project, including the three new wireless alarms, took about 10 minutes an alarm - well under an hour. But it helped to do a little research first. I used a wireless drill and an 1/8 drill bit. It's easy to mark the holes with the hardware provided - just follow the instructions on good locations to place the alarm, like out of corners, if possible, and away from the water heater, etc. Drill your holes, hammer in the anchors, then secure the anchoring plate. After that, it's simply add the batteries to the alarm (I'm not sure why there is no face plates for the battery compartment (also, you have to push down on the last battery - see pic)). After the batteries, set which code you want all of your detectors to communicate with each other on (I just used a pen - see pictures attached), then attach the alarm turning clockwise until you hear the clicking noises (about a quarter turn). Remember, these connectors communicate with each other, NOT over your home WiFi. That's it. When you have them all up, test by holding down the button on one of them for 5 seconds. ALL of the alarms should sound. I checked each alarm, and one wasn't working ... but that was user error - I set the wrong wireless code, so I had to return and change it to match the others. Also, for those interested, I purchased most of these detectors in November 2015; they were made in April 2015.

Better Than Expected - Nice to get something That Works

After lots of reading, I finally decided that I'd purchase 6 new wireless interconnected smoke detectors, three Battery powered and three AC powered. My 18 year old home only had two AC powered units but no smoke detectors in the three bedrooms or Rec Room. After setting the dip switches, these went up like a dream, it took about 15 minutes to install all three. They interconnect wirelessly to the AC powered alarms, and smoke detected by one sets off all six! The third AC unit will be installed along with a flashing Strobe in my Bedroom, with a relay to operate a bed shaker as well. The Strobe will arrive tomorrow. These have a feel of quality, unlike some of the cheap units I've seen.

Appears to be good quality and easy to install

Appears to be good quality and easy to install. I have 3 of these and are all on same code so when 1 trips they all do. 1000 Sq ft rental house with 1 in central hallway and one below it in basement. Then I put the last one in my house which is next door approximately 80-100ft away inside next to the outside wall of that house. I tested it multiple times and it responds to alarms both ways. I then put the remote unit in a zip lock bag so it's not going to set off the other house with the 2 in it. It sounds goofy but my mom lives in the rental house and I live in the nexdoor one. This way if there is a fire in her house I get the alarm in my bedroom.

So easy to install and worth the peace of mind.

I bought 3 of these because if one goes off, they all do. And to compliment CO2/Fire alarm units. The problem with wireless combo fire alerts is they usually only are only able to detect Ionization fires and not get burning fires. These are photoelectric. The combination helps you stay safe. I have one of these in our living room because we have a wood stove, one in my bdrm because it is furthest room from wood stove and one in detached garage. So far very happy with them and love they link together and if needed I can link several more to them. Have tested them from all the locations and they always all go of.

Wireless alarms solve the problem of alarms to far away to hear properly -

We are all aware that fire detectors are vital for home safety - But they are not much good if the alarm is in an attic or basement - If they should go off most likely you will not hear them - Having a wireless alarm solves this problem - Now an alarm can be place anywhere and if you have one in your bedroom and,if the distant ones should go off because of smoke or fire the one in your bedroom will respond and you will be warned - The Kidde wireless alarms work faultlessly - I have two in the basement, two in the attic and one in the kitchen - I also have one each in all 4 of my bedrooms as well as in the living room area - I test them once a month and when one goes off all 10 respond and for about thirty seconds the house if filled with a raucous peeping sound which is exactly what you would want if there is ever an emergency -

Operates OK, but beware of mounting

We had a set of these that was installed 10 years ago. After the 10 years of service, the old ones started chirping, because they were due for replacement. So we ordered these as replacements. When we attached the first of the alarms to be replaced, we found that they have a very positive acting latch that locks them into the wall mounting ring. The old alarms could be unscrewed from the mounting ring like a light bulb. But to remove the new ones, you have to find the little plastic pin that locks the alarm into the ring and push up on it while you are unscrewing the alarm from its mounting ring. Probably the easiest way to go is to break off the little plastic pin, so that you won't have to fight with it when replacing batteries in coming years. That's what we did with most of ours.

Bargain

I bought one, the sound is loud and obnoxious, you're sure not going to miss a fire for sure and that is the point..I wouldn't want more of them communicating and going off simultaneously though..but you do you.. great value for its price it'll alert you to smoke..since I already have separate carbon monoxide detector on this floor it's all I needed..on my other floors I have a different detector that alerts with voice and gives location and will tell you if it's detecting smoke and/or carbon monoxide those are very nice too..this takes 3 batteries and my other (voice smoke/carbon monoxide detectors) take only two. This got here super quick, well packed and worked, what else can you ask for

Saved me from smoke damage or worse

Replaced the 30+ year old smoke detectors that were original to the house, and decided to add one battery operated one to the laundry room. It was super easy to link it to the hardwired ones with the wireless interconnect. Glad I did; about 3 months later I was outside on the other side of the house when I heard them all going off (over my radio and mower, mind you!). Ran inside to find the washing machine billowing smoke from a siezed belt, but since the closet doors were closed it was limited to the closet. Could have been much worse.
