Quick question. I have an ESFR application and the roof structure is made out of concrete tee's, 24" deep from inside face to bottom of stem. Looking over the cut sheet for the Tyco ESFR-25 Pendent it states that any solid member over 12" deep you need to install sprinklers in each channel formed by the structural members. When looking at the Viking ESFR VK510 (25.2K) I don't see those same parameters so I guess I would then go back to NFPA-13 (2013) and install per 8.12.4.1.3 correct?
