Abstract

The invention relates to devices for controlling accesses of the security chamber type which comprise at least two doors (2, 3). A single program selector (14, 15) with easy and instant control allows the security chamber operating program to be chosen at will from several predetermined programs.

Claims

1. A device for controlling an access of the security chamber type, comprising at least two doors each equipped with a lock with electrically controlled locking and a control device for applying to the security chamber n separate operating programs, where n is a finite whole number greater than 3, said programs including a program providing simultaneous locking of the two doors, a program providing simultaneous unlocking of the two doors according to at least two respective predetermined control modes, a program providing successive unlocking of the two doors according to at least two respective predetermined control modes, and at least one further program wherein a different control mode is provided for unlocking at least one of said doors, said device further comprising a single n position selector capable of easy and rapid actuation, and electric means, associated with said selector, for automatically applying to the security chamber an individual program of the n operating programs when the selector is placed in the position among its n positions which correspond to that program.

2. Control device according to claim 1, characterized in that the selector is controlled by means of a rotary knob with n positions.

3. Control device according to claim 1, characterized in that the selector is controlled by n push buttons.

4. Control device according to claim 1, characterized in that the selector is controlled by a keyboard with keys.

5. Control device according to claim 1, characterized in that the electric means associated with the selector includes means for providing wireless remote control.

6. Control device according to claim 1, characterized in that the electric means associated with the selector comprise a set of programs formed by a plurality of switches preset to their open or closed position, and associated with diodes.

7. Control device according to claim 1, characterized in that the electric means associated with the selector comprise a set of programs formed by a memory.

8. Control device according to claim 7, characterized in that the memory comprises a semiconductor memory associated with a computer able to use its contents according to the indications given by the selector.

9. Control device according to claim 1, characterized in that the selector is associated with coded safety means for allowing only the holders of a code to control the selector.
