Abstract
The bank security system detects unauthorised access through openings or walls. It comprises a network of air filled tubing across all surfaces and openings and connected into a central control unit. This contains a compressed air bottle, batteries and a balanced bell crank lever. The upper end of the lever is held upright by the air in a metal bellows attached to it. If the system is punctured, the bellow contracts and a ball drops to operate a switch and the electrical alarms. Another heavier ball on a chain also falls and opens an air valve to operate a loud whistle.
