Abstract
A detection system comprising a plurality of taut wire panels having vertical detection/sensor wires. The sensor wires are tensioned to position trigger plates associated one or more of the wires. Trigger plate movement causes an actuating means to indicate a sensor wire has been moved. In one embodiment, sensor wires and portions of the panel frame have similar coefficients of thermal expansion to substantially eliminate environmental expansion effects that may result in false alarms. Linked sensor wires on adjacent panel may signal movement of entire panels. Panels are monitored by panel controllers reporting to sector controllers that report to a central command computer that automatically numbers sector and panel controllers at start-up. Bi-directional communication enables alarms and system faults to be precisely located.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
