SYSTEM DESIGN
FirePro units are selected based on the size and configuration of the risk to be protected. The size is determined by the cubic measurement of the space. This measurement is the internal dimensions of the space, in your calculation DO NOT DEDUCT the space occupied by objects within the space. The configuration is the second consideration – the aerosol agent must be distributed within the risk.

The calculation must be made compartment by compartment. The compartment must be completely separate(including above the suspended ceiling and beneath the raised floor). The doors must, in the event of fire, be self-closing and if necessary be activated by the control system. Windows, (smoke/heat) hatches and/or ventilation systems must be and remain switched off and closed during the extinguishing. Leakage losses must have been considered and will, if necessary, form part of the calculation.

Leakage Allowances are specified in the design calculation module, these allowances are expressed in Square Meters and will need to be assessed in the final system design.

For the system design the calculation of the aerosol is a starting point, then the specific configuration of the risk, with final consideration stream length and clearances required.

Stream Length The distances shown under discharge length, are those to be regarded as a maximum to obtain a rebound of discharge onto the surface (such as the floor) that then guarantees a good homogeneous spread of the aerosol in the protected compartment. Stream Length MUST be taken into account when designing a FirePro® System.

Safe clearance A safe distance has been laid down in respect of (flammable) materials and persons for each individual FirePro® unit in relation to the discharge of the aerosol. Its value is given in millimeters, as can be seen in the table.
