Data Sheet 8 9 & Changes in Protection TablesData Sheet 8-9 & Changes in Protection Tables

• Protection tables based on– Ceiling height (not storage height, broader range goods)

– RTI (standard or quick response)( q p )– Orientation (upright or pendent)– Sprinkler K factor (~ nozzle size)Sprinkler K factor ( nozzle size)– No. heads at minimum pressure e.g. 6 heads @ 1.7 Bar
