Alarm Input wiring can be sensitive to electromagnetic interference so it is recommended to use a high quality shielded cable.
Strip only enough of the cable jacket and shielding to allow for proper wiring of the connector.
The shield foil/braid should be stripped to the same length as the cable jacket.
The shield wire should be stripped to the same length as the signal conductors.
The shield wire should be terminated at the controller using the dedicated shield connection of the supervised alarm connector. The other end of the cable shield should be left unconnected.
Ensure exposed shield wire does not come into contact with any other shield wires, the metal enclosure, or any other metallic surfaces.
Shrink tubing can be used on exposed shield wire to ensure unwanted contact with metal surfaces.
