We have a project where transformers are located on the periphery within a building's ground floor. There are 14 transformers within a single room. The life safety consultant has recommended for us to provide deluge system protection.
Is it required to provide a deluge valve for each transformer, or combine three or four transformers per valve?
Also, how should sprinkler flow demand - is it calculated by each nozzle, or should we consider the entire transformer area for protection? Under NFPA 15 we have assumed 0.25 gpm/sqft (or 10.1 lmin/sqm).
Thanks in advance.
