The SCS⁄SCE Building-Specific Operation and Programming Examples
The next set of equations to be determined is for the supply dampers. There are two control modules per damper, one with the capability to
close the dampers (the control module is referred to as a CON
OFF⁄CL
CM) and one with the capability to open the dampers (the control mod-
ule is referred to as a CON
ON⁄OP
CM). Let us assume that the four control modules for the two supply dampers are wired on the SLC loop for
the floor that they serve. For instance, the CON
ON⁄OP
CM for the first supply damper on floor 3 would be L3M3 and the CON
ON⁄OP
CM for
the second supply damper would be L3M7. The CON
OFF⁄CL
CM for the first supply damper on floor 3 would be L3M4 and the
CON
OFF⁄CL
CM for the second supply damper would be L3M8 (L3M5 and L3M6 would be the monitor modules for one damper, L3M9 and
L3M10 would be the monitor modules for the second). The two supply dampers per floor are to close when a fire is detected on that floor
and they are to open when a fire is detected on an alternate floor. However, the dampers are not to open or close in response to the manual
pull station. The CBE equation for the two CON
ON⁄OP
CMs of each floor would be:
If a device on floor 6, with the exception of the manual pull station, becomes ACTIVE, the CBE equation for Z206 will become TRUE. As a
result, all equations that contain Z206 in them will be TRUE. When the equations become TRUE, the CON
ON⁄OP
CMs become ACTIVE and
open all the dampers except those on floor 6. The CBE equations for L6M3 and L6M7 are the only equations that will be FALSE in this case
and subsequently not open the dampers on floor 6.
The CBE equation for the CON
OFF⁄CL
CMs of each floor would be:
OR(Z20x)
where x is one of the eight reverse software zones corresponding to the appropriate floor. If a device on floor 6, with the exception of the
manual pull station, becomes active, the CBE equations for L6M4 and L6M8 would become TRUE. When the equations become TRUE the
CON
OFF⁄CL
CMs are active and close the dampers.
The next set of equations to be determined is for the exhaust dampers. Let us assume that the four control modules for the exhaust dampers
are wired on the SLC loop for the floor that they serve. For instance the two CON
ON⁄OP
CMs for floor 5 would be L5M11 and L5M15, and
the two CON
OFF⁄CL
CMs for floor 5 would be L5M12 and L5M16 (L3M13 and L3M14 would be the monitor modules for one damper,
L3M17 and L3M18 would be the monitor modules for the second). The two return dampers per floor are to open when a fire is detected on
that floor and they are to close when a fire is detected on an alternate floor. However, the dampers are not to open or close in response to the
manual pull station. The CBE equation for the two CON
ON⁄OP
CMs of each floor would be:
OR(Z20x)
where x is one of the eight reverse software zones corresponding to the appropriate floor. If a device on floor 6, with the exception of the
manual pull station, becomes active, the CBE equations for L6M11 and L6M15 would become TRUE. When the equations become TRUE
the CON
OFF⁄CL
CMs are active and open the dampers.
The CBE equation for the CON
OFF⁄CL
CMs of each floor would be:
If a device on floor 6, with the exception of the manual pull station, becomes ACTIVE, the CBE equation for Z206 will become TRUE. As a
result, all equations that contain Z206 in them will be TRUE. When the equations become TRUE, the CON
ON⁄OP
CMs become ACTIVE and
close all the dampers except those on floor 6. The CBE equations for L6M3 and L6M7 are the only equations that will be FALSE in this case
and subsequently not close the dampers on floor 6.
