The SCS⁄SCE
Building-Specific Operation and Programming Examples
After the dipswitch settings have been determined, an EIA-485 device address for each SCS must be determined. As stated before, there are
32 available addresses. So, if no other EIA-485 devices are present on the data line (such as annunciators) the maximum number of SCS⁄SCE
pairs allowed is 32. For our example, we only need three available addresses. Let us assume that addresses 5, 6, and 7 are available. As
shown in Table 3.4 and Figure 3.4, set the dipswitches and addresses of each SCS.
The next step is to categorize all protocol points as needed, unneeded, or unused, as discussed in Section 2.4.2. Using the bottom portion of
worksheet 2 as a guide, our example for the SCS at address 5 would look like the following:
For AM2020/AFP1010 only: After categorizing all protocol points, the software type IDs can be selected as discussed in Section 2.4.2. All
protocol points that are needed get assigned software type IDs from Table 3.13. All protocol points that are unneeded do not get a software
type ID and do not get programmed into FACP memory. All protocol points that are unused get assigned the software type ID ACON. Use
worksheet 2 in Appendix B to organize this information.
Installation
At this point, all the preliminary design work is complete. The next step is to install all control modules and monitor modules on the required
devices, as shown in Section 5 “Ratings and Wiring Diagrams”, and install the SCS⁄SCE pairs as described in Section 2.2. Once the installa-
tion of all fans, dampers, control modules, monitor modules, SCSs, and SCEs is complete, the FACP requires additional programming for
smoke control.
Programming (AM2020/AFP1010 Example)
Programming SCS annunciator addresses, linking annunciator points with control or monitor modules, assigning control and monitor Type
IDs, and creating control-by-event equations to obtain desired fan and damper activity, are the steps required to complete the smoke control
setup. Refer to Programming in Section 2.4 for descriptions of the various programming processes. Following is a step-by-step description of
AM2020/AFP1010 programming for this example.
The first step to programming the FACP for smoke control is to define each SCS address in FACP memory. Refer to Section 2.4.1, EIA-485
Device Addressing, for instructions. SCS addresses 5, 6, and 7 must to be entered for this example.
The next step is to program all EIA-485 protocol points, including software type IDs. By referencing the worksheets, all the information nec-
essary is close at hand.
