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.

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.

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.

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.
