You mean "horizontal", I think. A flat roof is a horizontal by definition but so is a sloped one up to 2:12. SL -Original Message- From: Sprinklerforum [mailto:sprinklerforum-boun...@lists.firesprinkler.org] On Behalf Of Nick Maneen via Sprinklerforum Sent: Monday, October 14, 2019

We used the FM guidelines a few years ago at San Diego airport where luggage conveyors pass through the wall separating the interior from the tub bays outside. Two SSW or nozzles (can’t remember which at the moment, but I think sprinklers because the systems are all wet-pipe), located in the

What if the fire service downstream from this appliance supplies one or more private hydrants in addition to the sprinkler system(s) you’re considering? There’s your outside hose stream right there. If you have a warehouse with CDMA or CMSA sprinklers that require 500 outside in addition to
