<p>A remotely controllable, lockable container (1) for safekeeping an article such as a fire brigade key (13) for use in associated premises has an outer door (3) with an electrically operable lock (7, 8) to be unlocked from a remote control security centre, an inner door (10) having a mechanical lock (12) operable by means of a fire brigade master key, and a lock cylinder (14) operable by the key (13) in safe keeping to set a surrounding electrical switching device (15) which monitors the presence of the key (13). The container has further electrical monitoring devices (not shown) for monitoring the integrity of the container walls (2) and outer door (3) for penetration, and for signalling, at the remote control centre any unauthorised attempt at break-in into the container, as well as the status of the lock (7, 8). The electrical signals, in total, are combined, compared and/or rationalized in an electrical control device (17) to avoid false alarms the control device (17) being housed in the container (1) which thereby safeguards the device (17) against unauthorised interference and reduces to the minimum the number of long distance electrical conductors (not shwon) which have to be taken out through the cable duct (16) in the rear wall (4) of the container (1) to convey electrical signals to the remote control centre.</p> |
