Will this work if you have a duplex house ?

Yes as long as they are not too far apart to talk to one another.

Hello CJtheDJ, Thanks for reaching out. The units you are referring to are part of a specific model group that will only communicate with others in this grouping. Kidde units will only work with Kidde units. They are not universal.

Are these available in other colors

Hello Joe, No. they are only available in white

how far apart can these be installed ... what is their range for interconnectivity

Asked by toledodave December 8, 2020

Answers

I do not have the manufacturer's recommendations handy. The units in my home perform very well on two different levels--main and basement. The two units on one level are 25 feet apart. The distance from my kitchen to the nearest basement unit is 23 feet. The others are behind often-closed doors at a distance of 28 ft and 12 feet. When one unit is activated all units go off. It has greatly enhanced my home's safety.

Hello. This model will not fit onto an electrical box. However, we do have the wireless P4010DCSCO-W, part number 21027680 that is wireless and has a bracket that will fit onto an electrical box. Please note that these two alarms do not work together.

This is an interconnect device that interacts with other Kidde. It is for installation where wire interconnect is not possible. Whether it will reach out to other services or your wireless hub you would have to contact Kidde and discuss with them.

Yes, I have 2 mounted to the ceiling and the third on a wall. With one screw, you attach a small circular plastic piece to the ceiling or wall. Then press and almost screw on the detector unit to that plastic piece. Easy installation

No mounting bracket
I don't even know how these work, because we haven't been able to mount them. There is no little mounting bracket included, and judging by the other reviews, this is a frequent problem. If you want to buy this, put the batteries in, hang them up and be done - this is not your product. Now we're waiting for Kidde to send the brackets through the mail. Batteries are included, so there's that.

Easy to set up! Glad I made the switch to these. They work together when activated. I even put one in the garage in case something happens in there while were sleeping. If it detects smoke or carbon monoxide it will communicate with the one in the hall by our bedrooms to let us know!!!

Easy to install and link together. They are very loud when they go off so I have no doubt I will wake up when they go off. When one goes off they all go off.

These are a good product whether individual or "3-pack". The wireless connection was exactly what we needed and these are on all 3 floors and connect without issue. Easy setup and install with one screw. Tested one set off, and it will set all 3 off. Which I think everyone needs because you are not going to hear an alarm 3 floors away while sleeping etc. Hoping that the technology does work in an actual event while sleeping, but I believe this is still the best bet (bang-for-buck) for safety. I still have all my other separate smoke and CO alars, and while I am not home, my Leeo device listens for alarms and calls me in an event. Do not mess around. For ~$100 (daily deal) it is worth it. Even regular price is worth saving a life and possibly a house/building.

Installed 8 of these in my home in the fall of 2016. All of them activated within seconds one time since then from kitchen smoke. They are loud and sensitive. The carbon monoxide detector has not activated yet and I hope it never does. Look for the 2 pack ($80) if purchasing these as opposed to $50 for a single unit. I feel good knowing these detectors are protecting my home. The batteries haven't been changed yet and no low battery indication so far. I will change them in all 8 units when the first one indicates such then annually after that. I highly recommend these to anyone replacing or a new install.

Setup was very simple. Testing went exactly as advertised. Pressing the test button on one unit made all units sound the alarms. Once installed in the house, the lit match test near one unit worked flawlessly. The unit detecting smoke sounded the alarm first and announced "fire detected". Immediately followed by all three other units giving the same alarm. I purchased 4 of these at one time to replace aging units. The price for the twin pack was quite low. Get some piece of mind and get these.

This is a follow up review. I originally had issues with the first one of these I bought but Home Depot and Kidde were quick with solutions. I like being able to have a push notification go to my smartphone if an alarm is triggered. Also it is very easy to set up in Wink. If you have more than one of these connected to a single wink hub they all show up as one unit.
