Bottom of Duct is similar elevation to mechanical platforms. 1. Are supplemental design area beneath obstructions, separate from overhead design area, to be limited to the platform area, or to include additional under duct sprinklers to achieve design area of 1200 SqFt? 2. Where I have duct only, how many sprinklers beneath duct are required to be calculated? Sincerely; Jackie "JW" Ward; SET 1-405-240-7076 [email protected]<mailto:[email protected]> NICET IV Cert.
