Definition of compartments
The software is based on NFPA 13 Standards (NFPA 13D-13R for residential/dwelling units).
Each compartment can be associated with a room or directly to the building if the specific building data for the rooms is not available. The compartment contains all information about the level of hazard. This includes coverage area of the sprinklers, the working pressure and the total amount of devices to be installed. The user can modify and change these parameters at any time.

Sprinkler and Pipe drawing
Fire protection calculations are based on NFPA 13. The sprinkler terminals are considered from the hydraulic point of view as if directly connected to the main supply line. The head loss related to the connection pipelines between the main supply and the sprinklers (including the friction and local losses caused by elbows or Tee connections) is not required for the calculation.

This option is connected to the “on pipe” check present in the database of devises. The user can modify characteristics of the connection and the discharge rate in order to simulate commercial sprinklers.

Calculation
The program determines the most and the least demanding areas of the design based on the hydraulic and geometric configuration of the system. It then displays the friction characteristic curve, the working point of the system with pressure, flow rate and theoretical water storage capacity if the system cannot be connected directly to the street line.

Once the pump has been specified the working point is calculated by intersection between the characteristic curve of the system and characteristic curve of the pump. The storage capacity of the system will be updated based on the new working configuration.

Reports
The calculation reports contain hydraulic information including but not limited to; fluid pressure, head loss, upstream pressure and flow rate for each pipe. The software generates a Bill of Materials listing all equipment used in the design in either .RTF or Xls.
