220.127.116.11 Smoke Detection and Destratification Fans. The area of protection
for smoke detection devices permitted by NFPA 72 shall be reduced by 50
percent where destratification fans are used.
This restriction does not apply to thermal or flame
detection devices or to residential occupancies.

more zones, a graphic annunciator constructed of engraved
phenolic or metal material shall be installed at a location
determined by the host fire department.

prepared and submitted by a qualified fire alarm contractor. Shop drawings
