摘要

The fence or barrier is designed for installations which require a high standard of security. The fence consists of an interlinked metallic wire screen or netting. The metallic wire netting has an electrical resistance wire, preferably sheathed in a plastic material. The electrical resistance wire extends along the wire mesh. A resistance measuring bridge is connected to alarm circuits which transmit an alarm signal when a resistance variation is detected. This resistance variation will occur when the wire screen is damaged. Within the plastic sheath covering the resistance wire and parallel to this wire is a steel wire. The steel wire is insulated from the resistance wire and is designed to mechanically reinforce the wire mesh screen.
