Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
172 words
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.
Claim 2
Independent Claim
172 words
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.
Claim 3
Dependent Claim
22 words
