Which division would include the specifications for fire detection systems?

The correct choice is C, as Division 28 of the Construction Specifications Institute (CSI) MasterFormat specifically addresses electronic safety and security systems, which encompasses fire detection and alarm systems. This division includes detailed specifications related to the design, installation, testing, and maintenance of fire detection systems within a building.

Understanding the purpose of Division 28 is essential for project managers overseeing telecommunications and other service systems. Fire detection systems play a critical role in ensuring safety and meeting code requirements in any project. By including the specifications for these systems in Division 28, it aligns building safety compliance with the overall project documentation, making it clearer for project teams to reference the guidelines for fire detection and alarm systems.

Other divisions mentioned in the choices do not align with fire detection systems. While Division 22 deals with plumbing and piping systems, Division 25 pertains to integrated automation and smart building systems, and Division 31 focuses on earthwork and site preparation. These divisions address distinct aspects of construction and do not encompass fire detection, making Division 28 the appropriate selection for this context.
