Alarm system sensing device

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.
