Automated storage machine

I am looking at protecting the interior of an automated storage machine. It has lots of small bins in it and you type what you want into a keypad it brings that bin down to an access area so you can grab what you need. The machine is 30 or so feet tall and is designed to take the place of severa

I started in FM data sheet 2-0 section 2.2.1.6 ceiling slope. This directs you to the definition of a false ceiling in appendix A and Data Sheet 1-12. Appendix A says that a suitable ceiling would be 3/8” plywood or gypsum board or you could also use corrugated or sheet metal. It also directs

RE: Sloped Roof in ESFR system

I agree. I am trying to get them to follow FM’s guidelines for the ceiling construction, but they currently have an architect saying that an acoustical ceiling will be adequate. Since FM’s way will be more expensive, and the architect is approving it, the owner will most likely be going with t

My concern would be what is the ceiling constructed of. If it is an acoustical tile ceiling with no clips I would be concerned with the velocity of the fire plume popping tiles before operating a sprinkler. Peter Schwab VP of Purchasing and Engineering technologies Wayne Automatic Fire Sprinkle
