Abstract
The present subject matter relates to systems and methods for automatically determining the level of an open chute door in connection with a chute system in a building structure. The position of the open door on the chute is automatically determined, without requiring any configuration at each door on the chute, utilizing a daisy chain wire signal connection and a chute busy wire (enable signal) signal connection. Pulses or other signals are counted at a base station to determine the level of the open door.
