What are my options ?

FM has not banned ESFR systems. They have just stopped recognizing the ESFR term. Many sprinklers you know as ‘ESFR’ they simply refer to as a ‘storage sprinkler.’ Likewise as Travis and Craig noted, there are some sprinklers they recognize as ‘storage’ that are not identified as ESFR by the manufacturer. <http://www.SummitCoUS.com> Visit our Website at www.SummitCoUS.com Mark Sornsin Sr. Fire Protection Engineer Direct: 701-499-1391 Cell: 701-526-8585 From: Sprinklerforum [mailto:sprinklerforum-boun...@lists.firesprinkler.org] On Behalf Of Brian Harris Sent: Monday, June 04, 2018 9:26 AM To: sprinklerforum@lists.firesprinkler.org Subject: FM Mutual & ESFR Heads I may be having a senior moment but I swear I remember reading something about FM not allowing ESFR systems….. Is that even remotely true? Brian Harris, CET BVS Systems Inc.
