<p>A door access control assembly (10, 12) is provided for mounting on a door (11) or on a cabinet provided with a door, the control assembly comprising a self-contained access control unit (10), and a circuit board housing (12) adapted to be mounted on a planar surface of the door or cabinet wall. A printed circuit board (PCB) is mounted within the circuit board housing (12), and circuitry of the printed circuit board is configured to provide an output signal to a door lock release mechanism in response to suitable release signals generated by the access control unit. The self-contained access control unit (10) takes the form of an activation module comprising a module housing, and release signal generating circuitry housed within the module housing. The activation module has an electrical plug and socket connection (14) with the printed circuit board (PCB). The access control unit (10) may be mounted directly on the outer face (33) of the door or cabinet wall, with the circuit boarding housing (12) mounted on the inner face (34) of the door or cabinet wall (Figure 11). Alternatively, the access control unit (10) may be accommodated in an aperture (10') provided in the circuit board housing (12), that housing being mounted on the outer face (33) of the door or cabinet. <??>A range of interchangeable modules (10) is provided which have different actuating arrangements, such as key-pad, and proximity sensor. <IMAGE> <IMAGE></p> |
