Abstract
Sensors are carried by structural components, such as floors, walls, etc., of the building within the secure area. The sensor detects deflections of the various structural members in response to changes of the loading of structural members caused by the intruder and generates signals which are transmitted to a control center which receives the intrusion signals and generates alarm signals. The intrusion signals are transmitted to the control center through the building structure as impulsive loads applied to the building structure by transducers located in the secure area which are responsive to the signals generated by the sensors. The alarm signals generated in the control center are transmitted to security systems located in the control center, such as automatic door locking mechanisms, lights, audible alarms, disabling gas injecting systems, etc., by means of coded impulsive loads applied to the building structure by transducers located in the control center which are responsive to alarm signals.
