Abstract (en)

A security system for a lock (22) is mounted within the door (2) of a hotel safe. Bolts (4) of the electrically operated lock (22) for the door can only be retracted when a solenoid (72) controlling a locking pin (74) is energised by a microprocessor (40). The hotel guest inputs a personal code into memory (42) before locking the safe. To reopen the safe, the guest has to key in the same code using a keypad (6) on the front of the door (2). If the input code corresponds to the one stored, the solenoid (72) can be energised to allow opening of the lock. If the guest forgets the code, the safe can be opened by connecting a separate override unit thereto so that an override unit processor communicates with said microprocessor (40). The override unit is connected by way of a socket (18) and if the override processor means successfully communicates with the security system processor means (40) it is enabled to read, and subsequently to generate, a preset override code stored in the memory (42) whereby opening of the lock is enabled. <IMAGE> <IMAGE>
