Fire Sprinkler Installation
1. System Design Review: The installation team reviews the design documents provided by the fire sprinkler
designer to familiarize themselves with the system layout, materials, and specifications.
2. Material Procurement: The necessary materials and components, such as sprinkler heads, pipes, fittings,
hangers, valves, and supports, are procured based on the project requirements and design specifications.
3. Site Preparation: The installation team prepares the work area by clearing obstacles, ensuring proper access, and
protecting existing structures, finishes, and equipment to prevent damage during installation.
4. Pipe Installation: The main pipes, branch lines, and lateral pipes are installed according to the design plan. This
involves measuring, cutting, threading, and joining the pipes using appropriate fittings and connection methods.
5. Sprinkler Head Installation: Sprinkler heads are installed at designated locations, following the approved design
layout. The heads are securely fastened to the piping system, ensuring proper orientation and alignment for
optimal coverage.
6. Valve and Control Device Installation: Control valves, check valves, pressure-reducing valves, alarm devices, and
other control components are installed as specified in the design documents. Valve locations are determined
based on accessibility and code requirements.
7. Connection to Water Supply: The installation team connects the sprinkler system to the building’s water supply,
ensuring the appropriate connections, backflow prevention devices, and pressure regulating devices are in
place.
8. Pressure Testing: Once the system is fully installed, a pressure test is conducted to ensure the integrity of the
pipes and fittings. This involves pressurizing the system to the required test pressure and checking for any leaks
or abnormalities.
9. System Flushing and Commissioning: The system is flushed to remove any debris or impurities that may have
accumulated during installation. It is then commissioned, which involves verifying proper functioning, conducting
flow tests, and setting up any necessary alarm and monitoring systems.
10. Final Documentation: The installation team prepares as-built drawings, documenting any deviations from the
original design, and provides the necessary documentation for compliance, maintenance, and future reference.
Fire sprinkler installation work requires skilled technicians who are knowledgeable about fire protection systems, piping materials, installation techniques, and applicable codes and regulations. It is crucial to ensure that the installation is done accurately and meets the required safety standards for effective fire suppression in the building.
