    (54) A security system


    (57) A security system for protecting the contents of a security container such as a safe or strong box (11) from attack comprises detector means (33, 48, 121) for detecting any attempt to move the container (11) or to enter it other than by authorised means, and the apparatus includes trigger means (118) fired in response to signals generated by the sensors (33, 48, 121) when such signals are identified by trigger control circuits (51, 52, 107, 130) as constituting an alarm event. Firing of the trigger (118) causes release of dye, smoke or other contaminants whereby to render the contents of the safe or strong box valueless and to mark the perpetrators of the crime for ease of subsequent identification.
