Early Warning System
Should a TARDIS be invaded by a hostile force, the Architectural Configuration Program can lock or unlock any door in a TARDIS interior from the console (there is a white flash around the frame when a door locks or unlocks). Pass keys for the locks consist of a series of mental images that the TARDIS reads telegraphically. An example might be: Crimson 11 delight "smell of dust after rain.' The Early Warning System can be configured to monitor a particular door or set of doors in the interior of the TARDIS. Should the doors be breached, alarm lights and buzzers will activate in the room the Time Lord is currently in.
