The device has at least two doors, a control device and a lock space (1a) bounded by at least two doors (5,6) in the passage direction. The control device ensures that an outer door (5) and a first inner door (6) are not open simultaneously for controlled passage. A second inner door (11) can be pivoted into the lock interior, whereby the lock is constructed so that with the second inner door open an initiated escape procedure can be detected and the outer door opened. |
