Building-Specific Operation and Programming Examples
The SCS⁄SCE
The recirculation damper must have the capability to close in response to any fire condition. It must also have the capability to verify that it
is closed. The results of the capabilities required for each device are as follows:
By referencing Table 3.3 the corresponding switch group type can be obtained.
For each capability a device is to have, a control or monitor module will be necessary at the fan or damper. Each control (CON) capability
will require a control module (CM) and each verification (VER) capability will require an monitor module (MM).
For our example a total of 69 CMs and 69 MMs will be required.
The next step is to determine the configurations for the SCSs and/or SCEs to be used. Although there are many ways to configure the
SCS⁄SCE pairs, the following configuration will be used for this example:
•
The four type 5 fans and the one type 1 damper will be on one SCS with three switch groups unused.
•
The 32 type 9 dampers will be on two SCS⁄SCE pairs.
The configurations selected above are reference numbers 28 and 16 respectively from Table 3.5. The dipswitch settings from Table 3.5 for
each SCS should be noted for installation purposes at this time.
Dipswitches 1-5 from reference number 28 of Table 3.5 set four of the switch groups for switch
group type 5 and four for switch group type 1. Dipswitch 6 is in the ON position to select the
FSCS mode. Dipswitch 7 is in the OFF position to select Non-dedicated System operation.
Dipswitch 8 is OFF so that the end-of-line termination resistor is not installed. Dipswitch 8 is
only set to the ON position when the particular SCS is the last device on the EIA-485 data line.
This setting will be the same for two SCS⁄SCE pairs. Dipswitches 1-5 from reference number 16
of Table 3.5 set all the switch groups for switch group type 9. Dipswitch 6 is in the ON position
to select the FSCS mode. Dipswitch 7 is in the OFF position to select Non-dedicated System
operation. Dipswitch 8 is OFF for the first SCS⁄SCE pair so that the end-of-line termination
resistor is not installed. Dipswitch 8 is ON for the second SCS⁄SCE pair so that the end-of-line
termination resistor is installed. Dipswitch 8 is only set to the ON position when the particular
SCS is the last device on the EIA-485 data line.
