Examples of some FHC Fire Protection Calculations.
FHC can model and calculate many types of fire protection systems including fire sprinkler systems, deluge, water mist and many more, giving the fire protection designer the ultimate freedom.

Two Installations & one water supply |
|
An example two-installation control valves supplied by one water supply. The first installation is a grid roof sprinkler system designed to give 12.5 mm/min over 260m2, and the seconded installation feeds the in-rack sprinkler system. The FHC program calculated this system in under 1 second.

ESFR Sprinkler Installation |
 A ESFR sprinkler system can be model very quickly by using the 'Quick Grid' wizard. This can be useful for establishing pipe sizes and water source demand for a project at the development stage.
The 'Quick Grid' wizard can also be used for a more traditional grid system given a AMAO and design density.

FHC can model water mist system in accordance with NFPA 750.

 FHC can hydraulically model fire hydrant systems, configured as simple layout or loop systems. Any number of hydrants can be flowing and you can specify different flow and pressure from each hydrant if required.
If the hydrant system is to be feed from a pump supply then you can determine the actual flow rate from the hydrants or minimize the pipe sizes by using FHC’s auto pipe size command.

Deluge / Spray Installation |
 Deluge installation of any type can be model with the FHC program. In this example medium velocity sprayers are protecting a vertical cylinder. Within the FHC hydraulic model we specified an area for each nozzle and a minimum design density of 10 mm/min.
