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.
