Question: i current have a BRK smoke alarm that has 3 prong connection. do i have to rewire if i change to the kidde? does it come with an adapter?
Document: I followed the directions (for the most part) and found it only took about an hour to replace all six units. I did not need the Kidde adapter kit as I thought I might (which really is a waste since each package contains two adapters of which only ONE will work with the BRK unit wiring - so you end-up throwing a perfectly good adapter away as you can't use it) and easily attached the wiring harness directly to the house wiring after removing the BRK wiring harness.
This unit will be easier to remove and change out the back up battery yearly because you don't have to take of the base that attaches to the ceiling. I chose Kidde because the old model I am replacing had served us for about 10 years which is their life span. I had to change the mounting plate for the base of the unit unscrew the base,align the new base on the screws and retighten the screws. The wiring harness was the same as the old smoke alarm so that was no hassle.
The First Alert smoke detectors in my house were about 12 years old and started to give out false alarms. I bought this Kidde unit about 6 months ago and installed it with no problem, no false alarm what so ever. So I bought two more last week to replace the rest. Assuming your house is already hardwired with 4 wires interconnecting the alarm outlets, when one  alarm goes off, the cascade connection feature allows that alarm to trigger all connected alarms along the chain.
Replaced 12 year old AC only smoke detectors with no problems to keep my family safe with additional battery back-up on May 30, 2012. Less than 2 weeks in I was up at 12:47 am for a false alarm and 2:14 for the same. Finally figured out which one was faulty and disconnected it. Returning all 3 detectors and replacing with First Alert. First experience with Kidde and I have been cured from using Kidde products in the future.
My home was built with the BRK brand, which started going bad after just 5 years. I'm the second owner, so guess what? No warranty! I did the research and found out the Kidde alarms have great ratings, so called the company to ask a few questions. They were great, easy to contact, and friendly! That sealed the deal for me, so I ordered enough to replace all of the BRK brand. Replacement was really easy as each alarm came with the replacement pigtail.
They are super easy to install and super easy to change the battery and super LOUD but they are all interconnected so one false alarm leads to 5 (I have 5 in my house.) blaring smoke alarms and there is no way to know which one is faulty.Do yourself a favor, select a different smoke alarm and sleep soundly at night.
They also interconnect with other Kidde, Fyrnetics, Lifesaver, Firex and Nighthawk alarms, strobe lights and relay modules with interconnect functionality. After considerable trouble with BRK/First Alert false alarms, these proved to be extremely reliable. This is a superior product, a very sound choice.
Like one of the other reviewers, I bought a new home in which the contractor installed 8 of these Kidde i12060 ionization smoke alarms. They are wired into the home and interconnected. Last month, when the house was about 1 1/2 years old, all of the alarms started going off - at 3:00 a.m. Thinking it was a dead back-up battery, I replaced all 8 of the batteries with new ones.
These were replacements for existing Kidde smoke alarms (CO2 detectors are supposed to be replaced every 7 years, and regular smoke detectors every 10 years according to the manufacturer and several fire department postings). 3 of the 4 worked perfectly once installed. The 4th started beeping every 30 seconds at 2 a.m., about 12 hours after being installed. I replaced the Kidde battery that came with it with a brand new 9 volt and again about 12 hours later it started beeping.
Who hasn't gone back home and have their mom hand them a list of projects?!? !This trip it was to replace the 10 alarms in the house with this product. First night, 3 went off at different times. Thinking it might be old batteries, I replaced all 10. Second night, at least 2 went off and started noticing random chirps.Grouchy and tired, jumped online to see if there was some connection between possibly dirty power and false alarms.
Answer: yes
