FAQ
Q: What does the "T" designation in the Zurn ZW4004SS-T model number indicate?
A: The "T" suffix indicates the factory-set pressure profile for this valve. The Zurn ZW4004SS-T comes with a specific downstream pressure setting that is non-field adjustable, ensuring consistent performance for its designed application.
Q: Can the pressure setting be adjusted in the field?
A: No, the ZW4004SS-T is factory-set and non-field adjustable to ensure proper performance and compliance with fire protection standards. If a different pressure profile is needed, you must select the appropriate model variant (R, S, or U setting).
Q: What is the purpose of the integral supervisory switch?
A: The supervisory switch monitors valve position and provides an electrical signal (rated 3 amps @ 125 VAC) to the fire alarm control panel, alerting facility personnel if the valve is closed or tampered with, ensuring continuous fire protection system readiness.
