Abstract
A cable alarm system is provided that includes: a lock; a cable coupled to the lock and operative to conduct a current; a secondary wire coupled to the lock and parallel to the cable and operative to conduct a current; a current detector coupled to the cable and the secondary wire, operative to detect an interruption of a current in at least one of the cable and the secondary wire; a battery operative to supply power to the current detector; an alarm coupled to the current detector and receiving power from the battery; and a heat sensor coupled to the cable and the secondary wire.
Claims13
A cable alarm system comprising:
- a lock;
- a cable coupled to said lock and operative to conduct a current;
- a secondary wire coupled to said lock and to said cable and operative to conduct a current;
- a current detector coupled to said cable and said secondary wire, operative to detect an interruption of a current in at least one of said cable and said secondary wire;
- a battery operative to supply power to said current detector;
- an alarm coupled to said current detector and receiving power from said battery;
- and
- a heat sensor coupled to said cable and said secondary wire.
A cable lock, comprising:
- a lock;
- a cable having a first end and a second end configured to be coupled to the lock to form a closed loop and adapted to conduct current;
- a secondary wire coupled to the lock and adapted to conduct current;
- a current detector coupled to the cable and the secondary wire and configured to detect an interruption in a current on at least one of the cable and the secondary wire;
- an alarm to transmit at least one of an infrared alarm signal or a radio frequency alarm signal coupled to the current detector;
- and
- a heat detector coupled to the alarm and to at least one of the cable and the lock.
