Abstract
A door exit device may include a light source for indicating a status of the exit device. The light source may be capable of providing a first indication denoting that the exit device is in a first state (e.g., a dogged state) and a second indication denoting that the exit device is in a second state (e.g., an undogged state). Further, the exit device may include first and second parallel control systems capable of electronically controlling that status of the exit device. In some instances, a first parallel control system may supersede a second parallel control system.
