Controlling the Smoke Dampers

SMKDMPRS (SCX920S)
The SCX920S named SMKDMPRS is responsible for controlling the
smoke dampers on floor2, floor3, and floor4. Since these smoke dampers
are not used for HVAC, this is a dedicated controller.
Table 5-2 lists the programs that are used by the SCX920S for this
application.:
