Is anyone installing EC HSW heads under garage doors? I keep running into 16 ft wide doors (queue jokes: "just open the door"). It would be cheaper to install one EC head rather than a standard spray HSW on each side. I'm looking in the 2013 version of NFPA 13, and I see in 8.4.2 where it allows standard sidewall spray sprinklers under garage doors, which isn't mentioned for the similar section regarding extended coverage sidewall sprinklers. It is mentioned in the EC HSW section: 8.9.5.3.2 that sprinklers are required under obstructions over 4 ft wide such as overhead doors. I'm thinking this is just saying sprinklers are required under the garage door due to the obstruction, but not implying that EC HSW can be used. It seems to me that NFPA is already being "nice" to us by letting us use the Light Hazard spacing for these HSW heads under garage doors and spacing the heads out farther with EC heads is pretty liberal if you are worried about this head ever actually going off in a fire. I would be interested to know if there has been any testing on this.
