Chapter 3: Smoke control system programming
Smoke control sequence
commands
9 Close supply air dampers to
remote zones on central system
10 Close exhaust air dampers to
remote zones on central system
11 Start central system supply fan (if
not currently on)
12 Start central system return fan (if
not currently on)
13 Reset the static pressure control
(if present) to maximum allowable
value for all systems under active
FSCS control
14 Monitor air flow and damper
position at panel
Note: Multiple central systems serving portions of a fire floor will
require sequencing for each central system command consistent with
smoke control application
Dual duct smoke control system
Table 16 lists the sequence for a dual duct smoke
control system.
Table 16: Dual duct smoke control
Smoke control sequence
commands
1 AUTO OFF
2 Open central outside exhaust
damper
3 Open central outside supply
damper
4 Close central return damper
5 Reset duct static pressure controls
to maximum design levels
6 Close smoke zone hot duct
damper
7 Close smoke zone cold duct
damper
8 Open smoke zone exhaust
damper
9 Close adjacent zone exhaust
dampers

Objective
Limit smoke spread
Limit smoke spread
Pressurize adjacent zones
Create negative pressure in
smoke zone by exhausting
smoke
Monitoring and control
Confirms system operation
Objective
Overrides HVAC system
Reduce pressure
development in smoke zone
Limit smoke spread
Limit smoke spread
Maximize air flow and
prevent duct collapse or
failure
Isolate smoke development
Isolate smoke development
Reduce pressure
development
Prepare zones for
pressurization and limit
smoke spread
Smoke control sequence
commands
10 Open fully adjacent zone hot duct
dampers
11 Open fully adjacent zone cold duct
dampers
12 Configure adjacent zone mixing
boxes for maximum air flow
13 Close hot dampers to remote
zones on dual duct system
14 Close cold dampers to remote
zones on dual duct system
15 Close exhaust air dampers to
remote zones on dual duct system
16 Start central system supply fan (if
not currently on)
17 Start central system return fan (if
not currently on)
18 Monitor air flow and damper
position at panel
Note: Multiple dual duct systems serving portions of a fire floor will
require sequencing for each dual duct system consistent with smoke
control application.
Multi-zone smoke control
Table 17 lists the sequence for a multi-zone smoke
control system.
Table 17: Multi-zone smoke control
Smoke control sequence
commands
1 AUTO OFF
2 Open central multi-zone outside
exhaust outside dampers
3 Close central multi-zone return
damper
4 Reset duct static pressure controls
to maximum design levels
5 Close smoke zone air supply
damper
6 Open smoke zone air exhaust
damper
