Radio frequency security system and method for a building facility

A security system for a building facility where radio frequency tamper-indicating devices are placed in the area of the facility to detect movement and/or relative movement of components under circumstances where such movement may indicate a security risk. One example is where there are ceiling tiles in a false ceiling which may be moved during a covert entry. An RF damage indicating device is placed at juncture locations of the tiles and tendrils of the tamper-indicating devices are positioned so that movement of one of the tiles will break the tendril and cause an alarm signal to be given. In other arrangements, tamper-indicating devices could be attached to security-sensitive objects, containers for the same, and building-related components so that movement of these security-sensitive objects would also trigger an alarm. |

DETAILED DESCRIPTION The method of the present invention is arranged to reduce security risks in or adjacent to a building facility where there are in, or proximate to, the building facility components which comprise one or more of the following: a) building component(s) which are part of, or associated with, a building of the building facility; b) facility component(s) which are in or adjacent to the building and relate to functions or occupancy of the building facility; c) other component(s) which are in or adjacent to the building facility that are not included in building components or facility components.
Each of these components are further categorized as follows: a) security-sensitive components which comprise: i.
component(s) which themselves are security-sensitive (i.
e.
because of having or containing security-sensitive information or items or components which are of sufficient value to be security-sensitive); ii.
component(s) which are of a nature that if moved or otherwise tampered with in some manner such tampering may indicate a security risk; iii.
components which are both themselves security-sensitive and also are of a nature that if moved or otherwise tampered with in some manner such tampering may indicate a security risk; b) non-security-sensitive component(s), which include the items or components which are not security-sensitive.
The method of the present invention comprises providing at least one tamper-indicating device which in turn comprises a tamper-responsive section which comprises at least one tamper-responsive portion which has an intact condition and a non-intact condition.
In a preferred form of the present invention, this tamper-responsive portion has an electrically conductive portion which in the intact position is able to conduct electricity between first and second tamper related locations, and in the non-intact position is not able to conduct electricity between the first and second tamper related locations.
Also, the tamper-indicating device comprises a signaling section that is operatively connected to the tamper-responsive section in a manner to: a) provide a signal indicating at least one of; i
