摘要
Intrusion alarm device. Consists of the following elements: 1. A structural deterctor of moments directed by a member of the building situated inside the security area to protect, being sensitive to the deviation of the structural member induced by changes in the member's load, and being insensible to the longitudinal distortions of the member. 2. Devices for the transmission of signals to the control center. 3. Devices in the control center to receive the signs and generate in some signs of activation of the security system. The conversion of primary intrusion signals of intrusion sensors in mechanical impulses is made by transducers placed in the security area.
