Question asked by gestionjft on Jul 5, 2017

I am working on an ESFR conception and i am a little confused. The building i am working on consist of a non combustible, non obstructed construction, 39 ft roof and maximun 10 x 10 ESFR spacing. (see draft in attachment) My interrogation is the location of sprinkler between each channel as required by ( I wonder if i can use the rule of obstructions instead of spacing the sprinkler one half of the maximum allowable distance  from the W530 ? Because using the rule of one half will prohibit the ESFR conception because of a coverage less than 64 ft2.
