FireCalc Pro –AS Fire Standard

The professional fire sprinkler hydraulic design tool built for fire protection engineers, hydraulic designers, and building certifiers working to AS 2118.1, AS 2118.4, FPAA 101H, and FPAA 101D.

Calculate your town main system demand in seconds. Enter your hazard classification, pipe sizes, and site conditions, and FireCalc Pro instantly delivers a full pressure loss breakdown, duty point, and tank size.

WHAT FIRECALC PRO CALCULATES

* Total design flow (N x q x 1.12 per AS 2118.1 Cl. 5.2)
* Hazen-Williams friction loss across GF main, riser, and topmost floor pipework
* Static head loss (height above town main)
* Backflow Prevention (BFP) valve pressure loss from DN65 to DN200
* Sprinkler Control Valve (SCV) friction loss
* Residual pressure demand at most unfavourable head
* Combined sprinkler and hydrant duty point
* Water storage tank sizing with standard-specific run time and buffer

HAZARD CLASSIFICATIONS

All AS 2118.1 classes supported: LH Resi, LH E.C Resi, LH Std, OH1, OH1 E.C, OH2, OH2 E.C, OH3, OH3 E.C, OH3 Special, HH Process (density x area), and HH Storage (K-factor based: Q = N x K x sqrt(P)).

DESIGN STANDARDS

Switch between AS 2118.1, AS 2118.4, FPAA 101H, and FPAA 101D. Each standard applies its own design multiplier, tank buffer, run time, and minimum head pressure automatically.

HYDRANT FLOW TEST AND SUPPLY ANALYSIS

Log field hydrant flow test data and plot supply curves. FireCalc Pro interpolates available pressure at your duty flow and tells you instantly whether the town main supply is adequate or deficient.

PROFESSIONAL PDF REPORTS

Generate a full hydraulic calculation report including cover page, pressure loss analysis table, water storage derivation, BFP comparison, and supply curve chart with duty point.
