I would like to add 2 more hardwired detectors to my basement. There already exist one there that works.
Is it OK to just take 14/3 wire, tie it into the existing one, and then run the other two in series off the existing one? I am assuming it is since the 14/3 will provide unswitched power as well as the interconnect.
Also, I did make sure my new detectors are compatible with my existing ones.
THanks
