Install electrical wires in the electrical panel or fuse box towards the smoke detectors. First, operate a 12-2 NMB using the ground wire in the panel towards the first box. This gives a hot, neutral, and ground wire. Mark "hot wire" about this bit of wire in the box.
Next, operate a 12-3 NMB wire using the ground in the first box towards the second box. Should there be greater than two boxes, operate a 12-3 NMB using the ground wire to all these boxes also. No box must have greater than two wires inside it when you're finished.

Result in the Connections
Within the first box, connect the 2 black wires together and add some black wire in the smoke detector connection. Now tie all of the white-colored wires together. Tie the bare copper ground wires together and operate a pigtail to bond it towards the box. Connect the red wire towards the interconnect wire in the smoke detector. This wire will often be marked and is generally a yellow wire. Make each reference to a wire nut large enough to pay for all uncovered wires.

CAUTION! Before connecting the black wire towards the breaker, make certain the breaker is incorporated in the OFF position. Now, connect the black wire to some 20-amp breaker or fuse. Mark the panel schedule using the placement location from the breaker you linked to.
When there is not an extra breaker, you may either give a breaker or hook it up for an existing circuit that does not cash link with it.
