Model RDPSP1 plug-in supervisory switch is a special application device to be used where no other approved or listed method of protection is available or practical. When installed on a handwheel operated valve, 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 will require removal of the cover. Tamperproof screws are provided for the cover. Removal of the cover, cutting of the cord, or ground faults will cause an open circuit. The device should be wired to the trouble circuit of a fire alarm control panel. The RDPSP1 is capable of operating on Class A or Class B circuits.
