Inetrconnecting FireEX smoke detectors
I am finishing my basement and need to add some smoke detectors. Once complete, there will be 12 in the whole house, upstairs and in the basement. This s the maximum that can be interconnecetd. The original 7 are 10 years old so I have bought 12 new units of the same brand (hoping their quick connect plug hasn't chanegd :)). So I'm all set for well inter-communicating detectors.
The problem is this...
I need to know if it is OK to have their "interconnect" wire laid out in a partial "star" pattern.
I can tap into the "chain" of existing detectors, but it will be easier to tie into the middle of the daisy chain. It is possible to start at the first detector on the end of the existing daisy chain (I am presuming they are daisy chained - no easy way to know for sure). But if I start at the last detector (which happens to be in the basement (existing), and then daisy chain to each new detector, I will have a lot of extra wire runs. I'd have to show a plan to show why.
Does it make any difference where I tap the new line of detectors into the existing "interconnect" wire? The 110v is not a problem.
