Abstract
A door system includes a support connected to a structure, and a door mounted on the support and movable relative to the support between an opened position and a closed position. The door includes a detection device and a remote module coupled to the detection device. The remote module includes a battery and an RF module for supporting two-way communication and sending signals indicative of the status of the detection device and the battery. The door system also includes a motor to drive the door, and a controller to control the motor. The controller includes a user interface and a memory. The door system also includes a base module coupled to the controller for receiving signals from the remote module. The received signals are indicative of the status of the detection device and the battery. The base module also sends signals related to successful transmission acknowledgements to the remote module.
