Abstract: 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).

Abstract: A barrel lock assembly 1 comprises a tubular housing 2 formed with a longitudinal access slot 4 extending through the wall of the housing 2; an inner barrel section 6 formed with an array of locking pins 8 extending upwardly from an array of slits 10; an electrically driven actuator 12 comprising a solenoid 14 and an actuating bar 16. In the assembled state (as shown in FIG. 2) the bar 16 is received by the access slot 4. The inner barrel 6 has extending from one end thereof a square peg section 18. A catch member 20 is fitted onto the square peg section 18. At the opposite end of the inner barrel there is a disc-like section 22 formed with a keyhole slot 24. Extending radially from the section 22 is a handle 26.
