Abstract
An overhead door interlock device provides an electrical signal indication of the locked or unlocked status of an overhead door, and interfaces with control circuitry of the door's opener to allow or disallow operation of the door based on the locked or unlocked status. In one embodiment, a lever is pivotably attached to the doors track, with the lever engaging with a switch mechanism to indicate the locked or unlocked status of the door. A spring mechanism automatically returns the lever to an unlocked position when the door's lock bar is retracted, with the lever mechanically inhibiting locking of the door until the lever is moved by a user.
