Figure 5.31 Motorized Damper Control
Non-dedicated System - FSCS Switch Group Type 9
Figure 5.31 depicts a motorized damper in a non-dedicated system with the capability of
OPEN and CLOSED control and verification of the
OPEN and CLOSED state, switch group type 9. In the above configuration, the CON
ON⁄OP
CM is activated and the CON
OFF⁄CL
CM is deacti-
vated. 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 con-
tactor is opened (cutting any power supplied by the EMS to the damper open power line), and the normally open portion of the dual contac-
tor 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 and the damper closed switch OPENs, indicating that the damper is in the OPEN position. The VER
ON⁄OP
MM monitors the
CLOSED position of the damper open limit switch and the VER
OFF⁄CL
MM monitors the CLOSED position of the damper closed limit switch. In
this case, the VER
ON⁄OP
MM is activated and the VER
OFF⁄CL
MM is deactivated because the damper is OPEN.
