Estimate aerosol compound mass from enclosure size and the design density for your application.
How this calculation works
m = V × dₐ × fₐ, where V = length × width × height, dₐ is the final design application density and fₐ is the additional design factor. The design density already includes the applicable safety factor; do not add it twice.
This estimates compound mass. A final design also covers generator selection, room leakage, fire risk, clearances and release controls, using FirePro’s design manual.
The protected volume, fire class, occupancy and generator model must fall inside the exact listing or approval.

Technical considerations
FirePro's non-pressurised generators transform solid FPC compound into a potassium-based condensed aerosol that interrupts the combustion chain reaction.
A complete aerosol system includes fire detection, release controls, warning devices and any required equipment shutdowns.
FirePro states a certified 15-year generator life under its specified operating conditions.

Frequently asked questions
Quick answers
Does FirePro reduce oxygen to extinguish a fire?
FirePro states that its potassium-based aerosol suppresses combustion mainly by interrupting the chemical chain reaction, with negligible oxygen depletion.
Is FirePro suitable for every room or cabinet?
No. Volume, leakage, fire class, occupancy, clearances, residue sensitivity and the applicable listing determine suitability.
Can FirePro connect to a conventional or addressable fire alarm system?
FirePro states its systems can be paired with conventional and addressable detection and control. A designed release-control arrangement connects the detection system to the generators.
What information is needed to size a FirePro system?
Provide enclosure dimensions, openings, ventilation, contents and normal occupancy. The designer also needs the required approval and any equipment shutdowns. Room volume alone is not enough.
Can a FirePro generator be reused after discharge?
A discharged generator must be replaced. Before restoring protection, investigate the discharge, inspect the controls and follow the manufacturer’s cleaning and replacement instructions.
What maintenance does a FirePro installation need?
Follow the system manual and maintenance schedule. Checks include generator condition, release circuits, alarms and changes to the enclosure or ventilation. Record the replacement dates specified for the installed equipment.
