Solenoid Monitoring Switch (SMS)

The Solenoid Monitoring Switch (SMS) consists of a supervisory switch, flexible connector, and a junction box. The switch is designed for use on Viking VSH200 or VSH1230 Clean Agent Suppression Systems to meet new NFPA 2001 requirements for a Manual Extinguishant Disablement Switch. It provides a supervisory signal at the releasing control panel when the electrical agent container actuation device has been removed from the container valve.
