This manual describes the installation, operation, and maintenance of Viking's preaction sprinkler systems.
This document serves as a technical manual for Viking preaction sprinkler systems, providing instructions for installation, operation, and maintenance. It details the system description, including the use of Model E, F, G-2000P, G-3000P, and G-4000P valve assemblies, and explains how these systems meet standards such as NFPA 13.
The manual categorizes systems into Single Interlock, Double Interlock, and Non-Interlock types, each with specific release mechanisms like pneumatic, hydraulic, or electric. It further outlines system requirements, procedures for placing the system in service, inspection and testing schedules (quarterly and annual), removal from service, and comprehensive troubleshooting guides for various components and fault conditions.
| Valve Models | Model E or F series deluge valve, Model G-2000P, G-3000P, or G-4000P valve assembly |
|---|---|
| Pneumatic Actuator Pressure (Low) | 30 PSI (2 bar) |
| Pneumatic Actuator Pressure (High) | 50 PSI (3.4 bar) |
| Supervisory Requirement | More than 20 sprinklers |
The three basic types are Single Interlocked, Double Interlocked, and Non-Interlocked.
A minimum of 30 PSI (2 bar) air pressure is required for system water pressures of 175 PSI (12 bar) or less.
The system must be automatically supervised if there are more than 20 sprinklers on the system.
