I think Travis is right, except for ceiling-only protection for ceiling heights over 40 feet. Then you go to 8-9, 2.3.6.9.6, which tells you to use 3-3-3-1 for slopes up to 5 degrees and 4-4-2 for ceiling slopes over 5 degrees.
I think this is new for the update in July 2020. -Kyle M -----Original Message----- From: Sprinklerforum <[email protected]> On Behalf Of Travis Mack via Sprinklerforum Sent: Thursday, October 1, 2020 6:16 AM To: [email protected] Cc: [email protected]; [email protected] Subject: [EXTERNAL] Re: FM 8-9 You have to look at 3-0 ( I think) for the shape factor and calcs. It depends on slope. It will be either 1.2 or 1.4. Depending on your spacing will determine how many sprinklers on the line.
