System Sensor’s PSP1 plug-in switch is a special
application supervisory switch designed for
applications where no other type of listed valve
supervisory switch can be installed.
Features
Application Flexibility. The PSP1 is to be used on non-rising stem
gate valves and ball and angle valves. The unit is approved for Class A
and Class B circuits.
•Monitors non-rising stem gate and ball and angle valves
•NEMA 3 rated enclosures
Robust Construction. The PSP1 consists of a rugged rain tight
metal housing. With its NEMA 3 rated housing and water-resistant
cord, the PSP1 may be used in either indoor or outdoor applications.
•360° mounting design provides greater installation flexibility
•Adjustable length supervisory cord
•Lockout feature ensures alarm signal integrity
Simplified Operation. The PSP1 features a 360° versatile mounting
design and an adjustable length cord which allow more freedom to
install the unit at the most desirable alignment angle.
•Cover tamper switch factory installed
•Tamper-resistant cover screws
Reliable Performance. The PSP1 employs a supervisory cord
which, when pulled out, closes a set of normally open contacts. A
lockout feature prevents reinsertion of the cord until the cover is
removed, and the unit is reset. Removal of the cover or cutting of the
cord results in an open circuit.

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
