Technical Specifications
Comprehensive hydraulic performance data, water distribution analysis, and installation parameters for all Fenix fire sprinkler models — backed by UL and FM certification testing.
1. Hydraulic Performance — Flow Rate vs. Pressure
K-Factor = 5.6 (80 metric). Formula: Q = K × √P where Q is flow in LPM and P is pressure in bar.
- Actual Flow Rate (LPM)
- Minimum Required (LPM)
0.5 bar
18.5 LPM
1.0 bar
26.2 LPM
1.5 bar
32.1 LPM
2.0 bar
37.1 LPM
3.0 bar
45.5 LPM
4.0 bar
52.5 LPM
6.0 bar
64.3 LPM
8.0 bar
74.3 LPM
12.0 bar
90.9 LPM
2. Response Time Index (RTI) Comparison
RTI measures thermal sensitivity. Lower RTI = faster activation. QR sprinklers (RTI ≤ 50) activate significantly faster than SR (RTI ≥ 80).
RTI Values by Product Series
Time to Activation vs. Ambient Temperature
At rated temp. 68°C, gas temperature ramp rate: 5°C/min
- QR Response Time (s)
- SR Response Time (s)
3. Water Distribution Coverage Comparison
Maximum and minimum allowable coverage areas per NFPA 13 and FM installation requirements.
- Max Coverage (m²)
- Min Coverage (m²)
4. Multi-Pattern Water Distribution
Radial water distribution comparison across sprinkler types — top-down view showing discharge intensity by direction.
- Conventional
- Pendent
- Sidewall
- Upright
5. Design Density by Hazard Classification
Required water application density and design area per NFPA 13 for different hazard occupancies.
- Density (mm/min)
- Design Area (m²)
