LEGEND
This allows the space to be overpressurized relative to adjacent
zones and prevents or slows entry of smoke into this space
from adjacent zones. See Fig. 82 for wiring.
EVACUATION — Evacuation mode removes smoke or un-
desirable air from interior spaces without reintroducing unsuit-
able air. The factory-installed optional economizer with option/
accessory power exhaust is required for this function. Evacua-
tion is accomplished by the following:
• turning the supply fan off
• opening the economizer (option required)
• running the exhaust fans (option or accessory required)
• opening the exhaust dampers.
See Fig. 82 for wiring.
