Which documentation must be provided for all fire alarm system installations?

• A. Calculations
• B. Floor plans
• C. Equipment list
• D. Riser diagram

Answer: (D)

The key idea is showing how the fire alarm system is distributed through the building vertically. A riser diagram maps the vertical path of the system—where the main control panel sits, how cables and wiring run between floors, and how devices on each level connect to the system. This vertical routing is essential for proper installation, inspection, and future maintenance, because it confirms that circuits, power supplies, and interconnections are laid out correctly across all floors. That’s why a riser diagram is the required documentation for all fire alarm installations: it provides a complete, floor-to-floor view of the system’s wiring and device layout, which inspectors and technicians rely on to verify compliance and to troubleshoot or modify the system later.
