ABSTRACT:
A backup gate controller for a motorized gate detects the loss of power to the gate and causes the gate motor to open the gate in response to loss of power or by an external trigger thereafter. The backup gate controller may be inserted between an existing gate controller and gate motor to bypass the existing controller when power loss is detected. Alternatively, the backup gate controller may be directly connected to the existing gate controller to cause the existing controller to open the gate when power loss is detected. A combined gate controller/backup controller may also be provided. Upon opening the gate, the backup controller and/or the gate controller may prevent the gate from being closed. The backup controller is battery powered and preferably includes a battery charger.
