together above the roof staging area and lead to the exhaust fan
system. The collection duct can be as much as 2438 mm wide and
the bottom should be no closer than 2134 mm to the staging
b) The design capacity of exhaust fans should be
based on the simultaneous operation of compartments or 46 256
L/s "air out." For ventilation air per compartment, see Table
c) The anticipated control is by device computer and
is as follows: When a fire is initiated, the building exhaust
system should control from flushing to full design ventilation.
The damper for the functioning compartment should open to a full
design ventilation position. Dampers in nonfunctioning
compartments should remain in their minimum flushing position.
d) Although smoke should not be admitted directly
into corridors, roof entryways should have an exhaust duct to
capture any stray smoke. The duct should discharge into the
main exhaust duct through a manual damper.
instructor's station is expected to add 5274 W to the air
conditioning load. Normal occupancy should be eight people.
The electronic room below the instructor's station has an air
conditioning load of 9816 W due to equipment. Individual
thermostatic control of each area is required.
Electrical. The power for the device should be 75
kVA. Provide 120/208-Vac, three-phase service. Provide four
lights for each training compartment switched by compartment.
Locate a switch for each compartment by the closest crawl space
door and another outside by the emergency door. These light
fixtures should be provided to light the training compartment by
shining up. There should be six lighting circuits per crawl
