Thank you, Bob Knight, CET III Fire by Knight, LLC 208-318-3057 From: Sprinklerforum [mailto:sprinklerforum-boun...@lists.firesprinkler.org] On Behalf Of David Williams via Sprinklerforum Sent: Thursday, August 15, 2019 12:43 PM To: sprinklerforum@lists.firesprinkler.org<mailto:sprinklerforum@lists.firesprinkler.org> Cc: David Williams Subject: Attic/Concealed space access to sprinkler heads I have a project intended to be fully sprinkled with a combustible attic that tapers from 2’ to 4 ‘ without being filled to within 2 inches of the deck with insulation. So I am planning on a dry pipe system with standard heads as the design of the attic does not allow the effective use of special application attic sprinklers. The questions are: whether inspection access is required to be provided, is it prudent to do so at the heads, or can the locations just be noted on the gypsum mounted to the bottom chord of the open web trusses.
