Marshall and fellow forumites: Without knowing all the details , I would say that in most cases because the square footage is over 12,000 sq.ft. the IBC would require it.
The topic is very apropos to us at this time. We are in preliminary design of a foreign petrochemical facility, where our own automation and control people are adamantly opposed to providing even pre-action sprinkler protection in the control/computer rooms. They claim that it is never done in the petrochem industry and that they don't want to be the first ones to try it. That country's building codes do not prohibit it. We have exhaustively pointed out all the advantages and disadvantages - property damage, business interruption potential, shutdown of operations, etc. Unfortunately, they don't get that the odds of smoke detection and accidental operation of a sprinkler are astronomical. We have also given examples of not relying completely upon gaseous extinguishing due to doors propped open, future holes poked in walls, stuck dampers, loose ceiling tiles, etc. I am not asking the forum for code references, statistical information on sprinkler system failures, reasons sprinklers should be provided, etc. We've addressed all of that. I would like to know of actual experiences anyone has on computer/control rooms suffering fire damage and shutting down operations - especially those that have only gaseous extinguishing. Articles would be especially helpful. I have personally witnessed an unsprinklered electrical room that completely burned and shutdown operations. Unfortunately, these folks say it's apples and oranges. Thanks in advance.

Each rack line is approximately 9 feet long and 3 feet wide. There is a 3 feet wide aisle between each rack line (2 aisles). Each rack is approximately 6 feet in height. Over each aisles, there is a lexan cover at 6-1/2 feet in height above the floor and a door at either end of the aisle, making a "room" 15 feet long and 9 feet wide in the computer room. This is for rack air conditioning. The computer room has a wet-pipe sprinkler system. 1. According to NFPA 101, the minimum headroom is 7 feet 6 inches. With the door access, would this "room" be required to have a 7 feet 6 inches ceiling? 2. To prevent sprinkler obstructions, would sprinklers be required in the "room"? Your opinions will be helpful.
