Museum collections are irreplaceable: the Louvre's Mona Lisa, the Spoonmaker's Diamond at Topkapı, the Hittite tablets at the Museum of Anatolian Civilizations. Fire destroys; water staining damages just as badly. NFPA 909 covers heritage-protection rules — pre-action sprinklers and aspirating smoke detection are the backbone.
Museum Risk Profile
- Fire: Wood, canvas, textile
- Water: Paper, parchment, miniature
- Smoke: Condensation on bronze
- Temperature: 50 °C+ cracks varnish
- Humidity: RH 45-55 percent fixed
Pre-Action Sprinkler
- Double interlock: Detection + sprinkler opening
- Dry piping: No water in the pipes under normal conditions
- N2 supervision: minimum 7 psi (0.5 bar) supervisory pressure (NFPA 13-2025 8.3.2.5.2)
- K-factor: K5.6 (K80) quick-response
- Density: 4.1 L/min/m2 light hazard (NFPA 13-2025 A.4.3.2 lists museums as light hazard)
Aspirating Smoke Detection
- VESDA: Very Early Smoke Detection
- Sensitivity: 0.005 percent obscuration/m
- Pipe: 50 m max per sampling
- Alarm levels: Alert/Action/Fire 3-stage
- Ceiling: Ideal for high-ceiling galleries
Water Mist and Gas
- Water mist: 50 micron, 0.1 percent water damage
- Inergen: Preferred for rare-book rooms
- FM-200: Electronics cabinet
- Clean agent: No post-fire residue
- Hybrid: Mist + sprinkler
World and Turkish Examples
- Notre-Dame 2019: Roof fire, masonry saved
- Rio Museum 2018: 20 M objects lost
- Topkapı: VESDA + pre-action
- Anatolian Civilizations: Ankara - NFPA 909
- Hagia Sophia: 1500-year mosaics

SprinkCalc — Fire Sprinkler Design Across Three Standards
SprinkCalc covers hazard classification, design density and area, K-factor selection, water demand and hydraulic calculations for NFPA 13, FM Global and BS EN 12845 in a single iOS app, and exports a professional PDF report. One of the few tools that unifies all three major fire protection standards.
