Sprinkler Systems

SF Fire & Ventilation Systems provides fully compliant engineering solutions for sprinkler and water-based fire suppression systems in accordance with national and international standards. All of our projects are designed and implemented based on the Turkish Fire Protection Regulation (2007 – 2019 amendment), EN standards, NFPA, and FM regulations.

In fire safety projects, our engineering approach is optimized by considering building type, hazard classification, and occupancy level. This ensures maximum safety and efficient water usage for each structure.

Engineering Approach in Compliance with Standards

At SF Fire & Ventilation Systems, all system designs are developed in accordance with:

• NFPA (National Fire Protection Association)
• EN (European Standards)
• FM Global standards

Within this framework, sprinkler, fire cabinet, and hydrant systems are evaluated individually or as integrated systems, and system capacities are determined through accurate hydraulic calculations.

Water Tank and System Design Criteria

According to the Turkish Fire Protection Regulation, water storage capacity for water-based suppression systems varies depending on the building’s hazard classification:

• Low hazard class: minimum 30 minutes water reserve
• Medium hazard class: minimum 60 minutes water reserve
• High hazard class: minimum 90 minutes water reserve

Water tanks are designed exclusively for fire-fighting purposes and are not permitted to be used for any other function.

Hydraulic Calculation and System Integration

In buildings where sprinkler, fire hose cabinet, and hydrant systems are used together, water flow rates are calculated based on the relevant Annex 8/A, 8/B, and 8/C tables. System pressure and flow values are determined through hydraulic calculations considering the highest sprinkler elevation point.

For systems equipped only with fire hose cabinets, designs are made in accordance with TS EN 671-1 and TS EN 671-2 standards, and integration with domestic water supply may be applied when appropriate.

In projects with external hydrant systems, a minimum flow rate of 1900 L/min must be ensured for at least 90 minutes, determined through hydraulic analysis according to building risk classification.

SF Fire & Ventilation Systems Assurance

At SF Fire & Ventilation Systems, our goal is to design and implement high-performance, long-lasting fire protection systems that are fully compliant with regulations in every project. All engineering processes are carried out professionally based on risk assessment and strict adherence to international standards.
