Abstract:
Automatic door systems and methods capable of determining proper functionality thereof are provided. The door systems are provided with a healthcheck module which automatically determines functionality of the door system by initially monitoring a first output signal provided by a first sensor and a second output signal provided by a second sensor. More specifically, the healthcheck module correlates the first output signal with the second output signal and operates one or more doors of a door system according to the correlation. The healthcheck module then monitors the second output signal provided by the second sensor to determine the ability of the one or more doors to close, and determines functionality of the door system accordingly.
