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.
