Plug-in Special Purpose Supervisory Switches are intended for supervision of non-rising stem gate valves and other valves that cannot be monitored by conventional supervisory switches. Turning the valve wheel will pull the plug out of the jack and close a set of normally open contacts. A lockout will prevent reinsertion and require removal of the cover. Tamperproof screws are provided for the cover. Removal of cover, or cutting of cord or ground faults will cause an open circuit. The device should be wired to the trouble circuit of a fire alarm control panel.
