摘要：
A security device may include a lanyard, a lanyard retention lock, and connectivity detection circuitry. The lanyard may include a first conductor and a second conductor that form an open circuit due to an insulator being electrically disposed therebetween. The lanyard retention lock may be configured to retain one or more ends of the lanyard to secure the security device to a protected object. The connectivity detection circuitry may be electrically connected to the first conductor and the second conductor. The connectivity detection circuitry may be configured to detect an occurrence of a closed circuit connection between the first conductor and the second conductor due to, for example, physical damage to the insulator, and may be configured to generate an alarm trigger signal in response to detecting the occurrence of the closed circuit connection between the first conductor and the second conductor.
