Abstract:
An electronic device is protected from unauthorized access by use of a security wrap having a security screen connected to an alarm circuit of the electronic device. The security screen has a pair of screen terminals interconnected by a conductor. The conductor is formed on a substrate. The substrate is arranged such that attempts to remove the security wrap will result in the substrate being torn and the conductor being damaged or broken whereby the resistance of the conductive path formed by the conductor changes to indicate an alarm condition.
