So i've got 6 smoke alarms roughed in. four of them have 2 red/black/white, and two of them have a single wire of each. One of the single wire rough ins is hot prior to installing the alarms.
After i've installed all the alarms (firex), none of them are hot (well the one box has a hot wire, but no green LED on the alarm). There is no power to any other alarm.
Pretty simple install, as i've just twisted and capped everything, blacks to blacks, whites to whites, and my read interconnected leads to the yellow firex connector wire.
Thanks in advance.
