    Carrier 48HC GAS PACK smoke detector and power exhaust help


    Attached pic of board on Carrier RTU, need to wire smoke detector in. Do I cut JMP3 and wire my 24v fan circuit through there?

    Where do I wire the power exhaust to? Is there a PEC power exhaust contactor coils? I'm looking at schematic in book and could they make it any smaller?
