Cable lock for security system
First Claim
1. A cable lock device comprising:
- a housing;
a cable having a first end fixedly attached to said housing, a second end which selectively attaches to said housing, and at least one wire disposed within said cable;
a switch disposed within said housing and configured to detect when the second end of said cable is attached to said housing; and
a tampering subsystem disposed within said housing, said tampering subsystem operable to detect whether said cable is cut at any point along its length;
wherein said at least one wire is electrically coupled to said tampering subsystem through only one end of said cable.

Abstract
A cable lock device includes a housing, a tampering subsystem, and a cable having a first end and a second end. The first end is attached to the housing and is electrically connected to the tampering subsystem and the second end is selectively attached to the housing. In addition, a switch is disposed within the housing and is electrically connected to the tampering subsystem. The switch is movable between an open state and a closed state to indicate when the second end is attached to the housing. The tampering subsystem includes control circuitry that monitors the position of the switch and the status of the cable to detect removal of the second end from the housing and/or severance of the cable. The control circuitry relays status information of the cable lock device to a control unit via a transmitter to alert a property owner of a security breach.

12. A cable lock device comprising:
-
a housing;
a tampering subsystem disposed within said housing;
a cable having a first end fixedly attached to said housing and a second end selectively attached to said housing; and
a lock fitting rotatably supported by said housing between a locked state and an unlocked state, said lock fitting including a bore having a plurality of first projections operable to properly align said second end of said cable in said unlocked state and at least one lock projection fixedly attached to said housing and disposed within said bore of said lock fitting to selectively engage said second end in said locked state;
wherein said tampering subsystem is operable to detect if said second end of said cable is disconnected from said housing and whether said cable is cut at any point along its length. - View Dependent Claims (13, 14, 15, 16, 17)
