What is a standpipe system that is divided into zones to limit maximum operating pressure referred to as?

A standpipe system that is divided into zones to limit maximum operating pressure is referred to as a multi-zone standpipe. This type of system is designed to ensure that different areas or zones within a building can have tailored water pressure according to their specific needs and fire protection requirements. By compartmentalizing the standpipe system into zones, it helps manage and control pressure fluctuations, which can be especially important in tall buildings or structures where excessive pressure could potentially lead to equipment failure or safety issues.

The focus on managing operating pressure is crucial in preventing hazards related to water delivery during firefighting operations. A multi-zone design allows for regulated flow and helps meet fire code requirements, making it essential for safe and effective fire protection. Understanding this type of system helps building managers and fire safety personnel ensure that fire protection systems are adequate and functional for their specific structural conditions and demands.
