Meters and standpipes can also be analyzed. FIRE calculates the gpm water flow and velocity through all pipe sections, the gpm flow and residual pressure at each sprinkler head, the pressure losses incurred in each pipe section due to both friction and elevation changes, the maximum system demand pressure, and the total water gpm demanded by the system. The report format is designed to aid both the designer and the plan reviewer. The FIRE Program uses the Newton-Raphson method for performing the hydraulic calculations. Calculations can be made for a given water supply pressure or they can be performed such that FIRE determines the lowest water supply pressure that adequately drive the sprinkler system.
Calculations are very fast and accurate.
The user manual lists all the pertinent equations to allow full manual verification. The FIRE program is a true Windows program complete with toolbars and hyperlinked help. All input is checked at the time of entry so that no improper data can be entered. If using AutoCAD and the SoftDesk Piping module, FIRE can take data directly from a CAD drawing file. Upon completion of the input process, all data is saved and can be reviewed and edited whenever desired.
