About this detail

This diagram details the security rough-in and low-voltage cabling connections for an access-controlled door opening, spanning between the finished floor and the accessible ceiling above. A card reader is mounted on the unsecure exterior side connected via a three-quarter-inch conduit and twenty-two gauge six-conductor cable terminating at a two-by-four-inch deep junction box with a single gang mud ring. On the secure interior side, a request-to-exit sensor is positioned six inches from the edge of the door frame and linked through a three-quarter-inch conduit and twenty-two gauge four-conductor cable. Recessed one-inch door contact switches monitor door position, while an electrified strike installed by door hardware connects via an eighteen-gauge four-conductor wire. A six-by-six-by-three-inch junction box located on the secure side above the finished ceiling consolidates these runs and transitions to a one-inch electrical metallic tubing conduit routing toward the cable tray, accessible ceiling, or nearest security panel.
