I think you do, unless somehow your EC heads meet that spacing criteria (which would be a horribly inefficient use of EC sprinklers). But I'm hoping someone will disagree with me and have a good answer as to why you don't.
-Kyle M From: Sprinklerforum [mailto:[email protected]] On Behalf Of James Crawford Sent: Tuesday, May 7, 2019 9:34 AM To: [email protected] Subject: [EXTERNAL] EC Heads and open Grid Ceilings We have an existing building that has extended coverage heads installed, the tenant improvement involves floating wood grated ceilings that are more than 70% open and will be about 18" below the sprinkler head. Light hazard occupancy. NFPA #13 (2013) section 8.15.14 Open Grid Ceilings does not make mention of EC heads. Do we need to change all the heads in this area to standard coverage heads?
