PSP1 Specifications
Architectural/Engineering Specifications
Model shall be a model number PSP1 special purpose supervisory switch as manufactured by System Sensor. The unit is not intended or designed for ordinary
usage. It is a special application device to be used for unusual conditions where no other approved or listed method of protection is available or practical,
such as non-rising stem gate valves. When installed on a non-rising stem gate 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. Tamper-proof 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 PSP1
shall be capable of operating on Class A or Class B circuits. The PSP1 shall be NEMA 3 rated for indoor/outdoor use and shall have an operating temperature
range of –4°F to 149°F (–20°C to 65°C). The PSP1 shall be listed by Underwriters Laboratories and Underwriters Laboratories of Canada, Inc. and shall be Factory
Mutual approved.
