Sprinkler Density & Coverage Planner
Estimate sprinkler count, design flow, coverage, and water demand.
Open ToolFire Protection Calculators
Sprinkler, fire pump, hose hydrant, tank capacity, and clean agent calculators for preliminary fire protection planning.
Fire protection workflow
Fire protection checks are highly authority-driven. Use this collection to compare sprinkler demand, hose and hydrant flow, pump head, water storage, and clean-agent quantities before formal hydraulic calculations are issued.
The calculators help expose missing assumptions: hazard classification, design area, hose allowance, residual pressure, duration, refill allowance, elevation, and authority-specific Civil Defense or NFPA interpretation.
Fire Pump Sizing Calculator
Estimate fire pump flow, head, jockey pump range, and pressure margin.
Open Tool
Fire Hose Reel / Hydrant Demand Tool
Calculate simultaneous hose reel and hydrant flow with duration and water volume.
Open Tool
Fire Water Tank Capacity Calculator
Estimate gross tank size from fire demand, duration, usable volume, and refill allowance.
Open Tool
FM200 / Clean Agent Quantity Estimator
Estimate clean agent quantity, cylinder count, and room-volume sensitivity.
Open ToolHow to use this collection
Start with the calculator closest to the project question, load the sample data, then replace values with your project assumptions. Use warnings and methodology notes to decide what needs formal verification before procurement, authority submission, or construction.
