Wireless communication system for a roll-up door

A wireless, two-way control system for a door, the control system comprising:

• an actuator connected to the door to move the door between an open position and a closed position;
• a controller connected to the actuator to control the actuator;
• a base module connected to the controller, the base module being adapted to receive and transmit signals;
• a battery operated remote module adapted to transmit and receive signals with the base module;
• and
• means for operating the remote module in a series of states, wherein in each successive state, the remote module consumes less current than in the previous state, and wherein the remote module returns to the first state in the series of states in response to the detection of an event by the remote module.

A wireless two-way communication system for a door comprising:

• a remote module mounted on the door adapted to transmit and receive signals;
• a base module adapted to receive and transmit signals with the remote module;
• a detection device coupled to the remote module;
• wherein the detection device is adapted to trigger an event,
• wherein the remote module is adapted to transmit a first signal to the base module as a result of triggering the event;
• and
• wherein the base module is adapted to transmit a second signal confirming successful transmission of the first signal.

A door system comprising:

• a door movable between an opened position and a closed position, the door including a detection device coupled to the door, and a remote module coupled to the detection device, the remote module supporting two-way communication, and sending first signals indicative of the status of the detection device;
• a motor coupled to the door to drive the door;
• a controller coupled to the motor to control the motor, the controller including a user interface and a memory;
• and
• a base module coupled to the controller for receiving first signals from the remote module, the received first signals indicative of the status of the detection device, and adapted to send second signals to the remote module confirming successful transmission of the first signals.
