The Viking VSH1230 Multi Zone Fire Extinguishing System utilizes selector valves that enable selective flooding of individual extinguishing zones. The selector valves are closed in operating status. After a fire has been detected in an extinguishing zone (or if the system has been released manually in an extinguishing zone), the selector valve that belongs to this extinguishing zone opens automatically and the extinguishing agent can flow into the extinguishing zone. This measure enables focused discharge of extinguishing agent in individual extinguishing zones and safeguarding extinguishing zones that are not affected.
