What is scary is - is this near you or in the lower 48? While the AF concentrations we need round here should be able to provide control, is there a concern for either an extended period of time for both the dry system to trip and the AF to flow thru to a point where WATER is discharging from the sprinklers? I don't know what you guys ended up with (or maybe DuPont is still working on it) so I'd just be cautious of the combined delay if the AF you use isn't something that provides control.
Oops- was thinking of Rod's location in tundra. Along the gulf stream in balmy NE megalopolis, Todd, should be ok. Unusual, imagine it's a "it doesn't say you can't" rather than searching for where it says you can. Maybe a nonparasitic FPE with significant AF experience could shed some better light on the AF portion of the question. Obviously the volumes involved and the occupancy (or nature of the occupants-ambulatory?) might influence feasibility more than compliance- whether you should, not if you can. You're a PE, so of course you can; but would you or should you is a different question (I know you know this). George L. Church, Jr., CET Rowe Sprinkler Systems, Inc.
