Expansion Boards

Expansion Boards
Access Control Expansion Boards are used to expand and upgrade access control systems by adding support for extra doors, card readers, keypads, inputs, outputs, and other security devices. These expansion modules connect to the main access control panel, allowing larger and more flexible security system installations for commercial, industrial, and office applications. Ideal for growing businesses, access control expansion boards make it easy to increase system capacity without replacing the main controller. Dr Lock Shop stocks a range of access control expansion boards compatible with popular access control and electronic locking systems.
