Questions & Answers
Will this work if you have a duplex house ?
Asked by Boston February 15, 2021Yes as long as they are not too far apart to talk to one another.
Why would you advertise this as interconnect if it doesn't interconnect with Kidde wireless smoke...
Asked by CJtheDJ January 9, 2021Hello 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
Asked by Joe December 25, 2020Hello 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, 2020I 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.
Mounting plate
Asked by Andrew June 17, 2020Hello. 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.

Asked by Brian May 13, 2020This 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.
Is it Compatible with the Ring Alarm home security?
Asked by Rosie May 2, 2020I don't think so it uses a different signal not wifi
Will these work with "Ring" Home security hub?
Asked by Doug December 28, 2019No, will not work with Ring. Will work with Wink hub.
Can they be wall mounted?
Asked by Broskizzle November 19, 2019Yes, 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
