Abstract: A security case includes a body and a lid. The lid is manipulatable between a closed and an open configuration. The case further includes a controller and a configuration sensitive switch connected thereto. An electro-mechanical locking arrangement and an audible indicator are connected to the controller to be controlled thereby. The controller is responsive to the configuration sensitive switch to cause the indicator to provide a first indication while the case is open, and to cause the locking arrangement automatically to lock the case when the case enters the closed configuration.
