A:Answer You wire it just like any other smoke detector. If you take an old detector out, and put this in, you're hooking it up the same way. There are instructions to fit the most common wiring scenarios, so it should fit most houses.
It should be noted that there are two versions of this thing. This is the wired one, but there is also a "wireless" one that has a Li-Ion battery that you have recharge periodically. The advantage of that one, of course, is that you can put it wherever without needing to wire it.
