What type of fire protection system is divided into different zones to limit maximum operating pressure?

A multi-zone standpipe system is designed specifically to manage and limit the maximum operating pressure by dividing the system into different zones. This zoning allows for more effective control of water pressure in various parts of a building, accommodating different heights, floor configurations, or specific fire protection needs in a building. By having distinct zones, the system is able to operate more efficiently and provides targeted resources where they are needed most while preventing excessive pressure in any single area.

This equipment is particularly useful in taller buildings where maintaining consistent pressure throughout can be challenging. Each zone can be independently controlled, which enhances performance during a fire incident.

The other systems mentioned do not typically employ zoning in the same way. A single-zone standpipe system does not provide this division and may lead to higher pressure issues in taller structures. Fire sprinkler systems have different operational functions and do not utilize zoning in the same context as standpipe systems. Mixed-type standpipe systems combine various features but still do not have the same focus on zoning as multi-zone systems do. Therefore, the multi-zone standpipe system is the optimal choice for limiting maximum operating pressure effectively.
