FirePro systems use the latest generation of our patented FPC solid compound. When activated the FPC (electrical activation) solid compound is transformed into a rapidly expanding extremely effective and efficient fire extinguishing condensed aerosol. The aerosol is propagated and evenly distributed in the enclosure with total flooding effect without increasing the pressure. Fire extinguishing is accomplished by the interruption of the chemical chain reactions occurring in the flame. Quantity is referred to the mass of FPC compound. Brackets are included. FP200S and 500S can be upgraded to automatic thermal activation, thermal sensor must be ordered separately.
