This algorithm will perform the following:
• If the FSCS override to close this damper (FL2SADmp.OVR.Cls) is
ON, then close the damper (Fl2.SASDmp = ON), and skip the
remaining nested If-then else statements.
• If the FSCS override to open this damper (FL2SADmp.OVR.Opn)
is ON, then open the damper (Fl2.SASDmp = Off), and skip the
remaining nested If-then else statements.
• If the FSCS override to exhaust Zone2 (Zone2.EXH) is ON, then
close the damper and skip the remaining nested If-then else
statements.
• If the FSCS override to pressurize Zone2 (Zone2.PRS) is ON, then
open the damper and skip the remaining nested If-then else
statements.
• If the automatic smoke control for Zone2 has been triggered
(Zone2.SMK = ON), then close the damper in order to exhaust
Zone2, and skip the remaining nested If-then else statements.
• If the automatic smoke control for any zone other than Zone2 has
been triggered (Zone1.SMK or Zone3.SMK or Zone4.SMK or
STRWL.SMK = ON), then open the damper in order to pressurize
Zone2, and skip the remaining nested If-then else statements.
• If none of the above events have occurred, then set the state of the
damper is set equal to the numeric DefaultDmprPosn. In this case,
the SmokeSelfTest program in the CX9200 sets the value of
DefaultDmprPosn in order to perform a weekly self-test.
