Abstract of the Disclosure Access to the room is provided only by a movable compartment which must be entered by a person, at an entry opening, and moved along an access path, to an access opening, in order for the person to enter the room. A magnetic detector is provided either wholly within the compartment, or along the access path, or partly within the compartment and partly along the access path to detect the presence of ferromagnetic masses, such as weapons, carried by a person within the movable compartment. Known locking means are provided so that, upon such detection of the presence of a ferromagnetic mass, movement of the compartment along the across path to the access opening can be inter- rupted so that the person is retained in the compartment. The compartment may comprise a box reciprocable along the access path between the entry open- ing and the access opening, or may be a section of a revolving door and, in either case, the compartment is formed of non-magnetic material. A television camera or the like may be provided either adjacent the entry opening or along the path to obtain a picture of a person entering the compartment.
