The CS Technologies ACE Wiegand access controller is a single door access controller which provides high security, easy programming and low-cost. The access controller allows control of a single door using a reader with the industry-standard Wiegand interface. The door can have a reader (any Wiegand reader with a standard 26-bit output), an exit pushbutton and an electric release. Cards or keys are used at the reader and if authorised will be given access.
