Switch Information
Typical Control Panel Connections
Switch Terminal Connections Clamping Plate Terminal
CAUTION
An uninsulated section of a single conductor should not be looped around the
terminal and serve as two separate connections. The wire must be severed,
thereby providing supervision of the connection in the event that the wire
becomes dislodged from under the terminal.

discharge AFFF, deluge, or chemical suppression systems.

The frequency of inspection and testing for the Model VS-SP and its associated protective monitoring system should be in accordance with applicable NFPA Codes and Standards and/or the authority having jurisdiction (manufacturer recommends quarterly or more frequently).
