New home construction facilitates the location of hard-wired security system
wiring and components during the early phase of the construction. Structured
wiring in new homes supports most of the needs of a well-planned multizone
security system. Phone lines, coaxial cable, and Category 5 cable are components

The exception is the wiring for door, window, and motion detector sensors. Inexpensive two-conductor wire must be installed in the interiors of walls between the controller location and each sensor. In addition, two-pair #22- gauge wire must be installed for all low-voltage powered sensors such as motion
detectors.

One pair is used for power and the other pair is used for signaling.
