Abstract

An alarm sensor device of two major portions. The first portion is a securely enclosed chamber containing one or more connector elements and the second portion is a specific length of cable having conductor paths for energy transmission and having at least one connector device attached to at least one free end of the cable with the connector being compatible with the connector element installed within the enclosed chamber. Separate and additional means for interconnection of the conductors within the chamber to conductors of energy originating from alarm system equipment at a remote location is also provided. The specific length of cable securely emanates from and thereafter terminates by connector means within the enclosed chamber thereby forming a closed loop of fixed and unalterable circumference thereby providing a loop to protectively encircle an object. Any attempt to enlarge the fixed circumference of the closed loop of cable for the purpose of removing it from the object will cause an alteration of the pattern of energy flowing within the cables thereby causing a remote detection of attempted theft and allowing the activation of an alarm signal warning system.

Claims

1. An alarm system sensing device attachment for use with alarm systems instruments and detector systems which monitor the stability of energy forms transmitted between remote locations comprising:

a housing having within a secure enclosed chamber, said chamber containing a number of connecting devices protectively recessed within and extending to and through the outer surface of the housing;

a flexible cable component containing within one or more conductive energy paths, said cable originating from within the interior of the protective housing and thereafter passing to a physical location outside of said housing, thereafter extending without interruption for a certain distance outside of the housing and ultimately terminating within said same housing, the final termination being accomplished by means of suitable recessed connector component devices;

the internal conductive energy transmission paths being completely concealed and protectively enclosed by the housing and the body of the connecting device components to provide the physical condition of self-protection and freedom from tampering and so as to establish a condition whereby the partial physical separation of the joined connector device components causes an interruption of the energy paths within prior to the time when a further physical connector component separation actually exposes to view those elements which comprise portions of said energy paths;

the connection devices being capable of simultaneously providing both the junction of energy transmission paths, and mechanical interconnections of adequate strength to resist accidental separation of the associated mating connector components;

said housing, said connecting devices, and said external cable component, providing a physical design wherein the housing itself and the external cable join together through the connecting devices so as to form in concernt a closed loop of invariable length of circumference thereby allowing the loop so established to encircle and thereby become securely attached to the narrow portion of an irregularly shaped object without the necessity of having any portion of the attachment device pass through openings or other apertures in the object itself;

means on the housing for communication with alarm system detection instruments located remotely;

the connector components, conduits, cables, and conductive paths being interconnected with the housing so that energy supplied to the device will establish pathways within the external cable portion and through portions of the interior area of the housing;

means permitting the device to be made compatible with detection instruments of desired form of transmitted energy; and

the several mechanical and energy conductive components of the device being interrelated so as to assure that the attempted enlargement of the established fixed circumference of the closed attachment loop will result in the interruption of alteration of the normal pattern of energy preestablished within said loop components thereby providing a means whereby the physical act of said loop enlargement may be remotely detected by instruments.

2. The invention in accordance with claim 1, wherein the means on the housing for communication with an alarm system detection instrument located remotely includes a separate suitable recessed connector device at a point on the surface of the housing separate from the described points of connection of the external cable component for the purpose of providing a secure method of allowing interconnection between the device and alarm system detection equipment requiring the use of physical interconnection of energy paths in the form of conductive transmission lines, the conductors, conduits, connectors and transmission lines permitting the device to be made compatible with detection instruments of desired form of transmitted energy.

3. The invention in accordance with claim 1, wherein the means on the housing for communication with an alarm system detection instrument located remotely includes a miniature energy radiating apparatus and a source of stored energy internally installed and interconnected within the housing to permit the use of the device with detection instruments which utilize energy transmission in the form of radiated energy.
