CYPEFIRE Pressure Systems version 2025.c updates the standards used, following the latest updates and improvements related to the graphic environment, incorporating EN 12101-13.
This new standard has simplified the number of cases from the former A, B, C, D, E and F classes to only two available cases, Class 1 and Class 2. The following table shows the analysis conditions for each of them:
| Parameter | Class 1 | Class 2 |
| Door opening force | ≤ 100 N | ≤ 100 N |
| Differential pressure | ≥ 30 Pa | ≥ 30 Pa |
| Air flow velocity | ≥ 1 m/s | ≥ 2 m/s |
| Initiation time | ≤ 60 s | ≤ 60 s |
| Operating time | ≤ 120 s | ≤ 120 s |
| Response time | ≤ 5 s | ≤ 5 s |
CYPEFIRE Pressure Systems continues to function as it did in previous versions, although two other interesting new features implemented in the new version 2025.c are detailed below:
- General options
Here you can find and edit the main parameters governing the analysis of the pressure differential system, such as air density and target pressure, as well as the different coefficients for calculating air leakage through doors, windows and building elements.
- Usual values
When entering the leaks of doors, windows or building elements, the usual values provided by the standard for the most common cases in construction can now be imported.
An old job can be read with this update, but the pressure differential system must be generated again, as the class and the calculation conditions are different. If, for any reason, a system needs to be calculated or redesigned with the repealed UNE EN 12101-6 standard, the previous version 2025.b of CYPEFIRE Pressure Systems is available from the BIMserver.center Store.
