About this detail

This electrical detail shows the conduit and rough-in requirements for a secure door access control system spanning from above the ceiling to the door frame. A six-inch by six-inch by four-inch junction box is mounted above the ceiling for door interface and power, connecting via a one-inch conduit to the nearest cable tray and three-quarter-inch conduits down to the door frame and back boxes. A single-gang back box is flush-mounted horizontally four inches above the center of the door frame on the secure side for a request-to-exit sensor. A four-inch by four-inch by two-and-one-eighth-inch deep box with a single-gang device ring is flush-mounted at forty-eight inches above the floor for a card reader, connected by a one-inch conduit down the wall. The assembly coordinates rough-in work by Division 26 with fit-up components by Divisions 8 and 28, including an electrified lockset, power transfer hinge, door position switch, card reader, and request-to-exit sensor.
