3.4.9 Point Assignment
Each toggle switch group of an SCS⁄SCE uses four EIA-485 proto-
col points (of the 64 available) to control and monitor a particular
fan or damper. Each of the four points is responsible for one of the
four capabilities listed in Switch Group Type (
CON
ON⁄OP
,
CON
OFF⁄CL
, VER
ON⁄OP
, VER
OFF⁄CL
). When a switch group is
assigned a particular switch group type, only those protocol points
that mimic the capabilities of the switch group type are needed. The
other points for that particular switch group are unneeded. The only
other category for protocol points is unused. Unused protocol
points are associated with switch groups on an SCS or SCE that are
not being used. Only needed and unused EIA-485 protocol points
must be programmed in the FACP for each SCS⁄SCE used.
Unneeded protocol points do not get programmed. See Section 3.9
“Programming” for information on programming FACPs and
annunciators for use with the SCS⁄SCE. The numbering scheme for
each of the 64 points follows the format below:
Where N is one of the 16 toggle switches of the SCS-8⁄SCE-8, as shown in Figure 3.5, or one of the 16 contacts of the SCS-8L⁄SCE-8L.
Example: What is the point number for the CON
ON⁄OP
point associated with toggle switch number 11?
Annunciator Point = [4x(11-1)+1] = 41
This information should be calculated for each switch group so that proper mapping between SCS⁄SCE annunciator points and the FACP
control and monitor modules can be programmed. This information will also be used to assign software type IDs to each of the 64 annuncia-
tor points (see Section 3.9 “Programming”).
Each protocol point classified as needed will have a control or monitor module associated with it. The control module associated with the
CON
ON⁄OP
protocol point is called the CON
ON⁄OP
CM. The control module associated with the CON
OFF⁄CL
protocol point is called the
CON
OFF⁄CL
CM. The monitor module associated with the VER
ON⁄OP
protocol point is called the VER
ON⁄OP
MM. The monitor module associ-
ated with the VER
OFF⁄CL
point is called the VER
OFF⁄CL
MM.
