ZSFZ Alarm Check Valve Specifications by globaldis is a document available to read on EtoBox.
This document provides specifications for Model ZSFZ Alarm Check Valves in 4, 6, and 8 inch sizes. The valves are designed to automatically actuate alarms when there is steady water flow into a fire sprinkler system, indicating a sprinkler has activated. They prevent false alarms from transient pressure increases by holding pressure at its highest value without opening. Installation and maintenance must comply with NFPA standards and authorities having jurisdiction to ensure proper operation.
