ABSTRACT:
This invention relates to a portable locking device having a wireless transmitter that transmits the condition of the locking device to the receiver of a security system. The locking device comprises non-rigid cable so that it can be easily connected to various objects. Cutting the cable triggers prevents power from reaching the wireless transmitter, and the lack of signal triggers the security system to issue an alarm. The portable locking device comprises parallel armed and disarmed circuits to supply electricity to the wireless transmitter, but the armed circuit is broken if the lock is tampered with or compromised when locked.
