Automatic door control apparatus
The present invention provides a control apparatus for automatic sliding doors that can be used with a plurality of door brands and models. The invention includes a control box and an idler pulley mounted to the door header. Both the control box and idler pulley can be mounted on a variety of door models by means of specific header brackets that are configured for each door model. The control box also provides a universal signal interface that can interpret sensor signals from a plurality of door models. A drive belt revolves on the idler pulley and is moved by a motorized pulley controlled by the control box. At least one belt bracket is fastened to the drive belt with a belt clamp, wherein the belt bracket is attached to a sliding door panel. Like the control box and idler pulley, the belt bracket can be used with a variety of door models and is attached to the sliding panel by means of a door bracket that is specific to the door model in question.
