Wireless tracker expansion boards are used with DoorKing models 1833, 1835, 1837, and 1838 telephone entry systems to expand their ability to control up to twenty-four entry points. Connecting card readers and keypads to the 1830 series controller is now possible without having to run wires to each device. These wireless tracking devices may also be used with DoorKing gate operators to provide gate status.
