Answer: 
Hello Chuck. No. Our alarms do not work in the same connected circuit with First Alert alarms, and they do not have the plug or the same bracket. It will be very important that you take down ALL of your older First Alert alarms before putting up any of the new Kidde alarms, and you will have to rewire the plug and change the bracket. If we can help you further, we are Kidde Product Support at Read More
