System sensor ceiling strobe coverage.
Where ceiling heights exceed 30 ft.
In sleeping areas a 110 cd strobe must be placed more than 24 below the ceiling or a 177 cd strobe must be placed less than 24 below the ceiling.
In non sleeping areas the nfpa requires that wall mount visible notification appliances be installed 80 to 96 above the floor 6 minimum below the ceiling and for ceiling mounted strobes no more than 30 above the floor.
It uses a universal system sensor b501ap base for installation flexibility and reduced inventory.
The nfpa specifies varying minimum required light out puts for non sleepingrooms shown in the table below.
