ABSTRACT:
A programmable activation system for the timed locking/unlocking of a security installation includes at least one activation module (10a, 10b) for unlocking an opening element (4) and apparatus for controlling the module to program a time value corresponding to the precise moment where the activation module (10a, 10b) will cause the unlocking of the opening element. The control apparatus includes at least one remote control element (30) constituting a mobile detachable or detached part from the activation module (10a, 10b) which constitutes a fixed part of the installation, these parts including communicating interfaces for the transmission of information, one of the two parts, mobile or fixed, including at least its own exclusive and unique identification code (IDC, IDD), which is transmitted to the other part and memories therein by memories (54, 56) arranged for systematically supplying a traceability of the programming in association with the identification code.
