Figure 5.29 Motorized Damper Control
Non-dedicated System - FSCS Switch Group Type 7
Figure 5.29 depicts a motorized damper in a non-dedicated system with the capability of
OPEN and CLOSED control and verification of the
CLOSED state, switch group type 7. In this configuration, the CON
ON⁄OP
CM is activated and the CON
OFF⁄CL
CM is deactivated. Under normal
operation (non-smoke control mode) both control modules would be deactivated, allowing the EMS system to freely control the damper. The
CON
ON⁄OP
CM controls two contactors: a normally closed contactor for the damper closed power line, and a dual normally open/normally
closed contactor for the damper open power line. The CON
OFF⁄CL
CM controls two contactors: a normally closed contactor for the damper
open power line, and a dual normally open/normally closed contactor for the damper close power line. When the CON
ON⁄OP
CM is activated,
the CON
OFF⁄CL
CM is deactivated, and vice versa. When the CON
ON⁄OP
CM is activated, the normally closed contactor is opened (cutting any
power supplied by the EMS to the damper closed power line), the normally closed portion of the dual contactor is opened (cutting any power
supplied by the EMS to the damper open power line), and the normally open portion of the dual contactor is closed, thus supplying power to
open the damper. When power is supplied to the damper open power line, the damper opens. When the damper completely opens, the
damper open limit switch is
CLOSED, indicating that the damper is in the OPEN position. The VER
OFF⁄CL
MM monitors the CLOSED position of
the damper closed limit switch. In this case the VER
OFF⁄CL
MM is deactivated because the damper is OPEN.
