Dear All  , 


Subject : Clean agent system ( FM200 Gas ) Nozzle Location In multi height area of Enclosure 


Good Day , 


Enclosure having multi heights in the FM200 System protected area .major portion of Enclosure area 80% ( Height 5.25 Meter) and Remaining Portion of Enclosure area 20% (Height 6.9 meter) .how the Nozzle installation would be in this condition. 


as per Manufacturer recommendation , if height of enclosure is above 4.9 meter , nozzle to be considered 2 levels  . I Have increased the gas quantity based on Enclosure heights &  not provided additional nozzles for 20% of ceiling area (Height 6.9 meter) as FM200 gas having positive and negative pressure at the time of Discharge stage . 


what my basic question is " shall i consider extra nozzle for 20 % of Ceiling depth "  or  is Enough to consider additional Gas based on Heights .
