FSCS firefighter smoke
control station
The FSCS, where required, is most often located in the
building’s fire command center. The FSCS is a remotely
networked panel, which also contains an FSCS series
graphic annunciator. Where the fire command center is
also located in the building’s central security center, an
SCS with a graphic annunciator may also serve as the
FSCS.
The FSCS series graphic annunciator, with network
support hardware, is capable of providing both
monitoring and manual control of smoke control system
components. The graphic annunciator, when combined
to the correct Signature Series modules, can be used by
firefighters to start and stop fans and open and close
dampers for smoke control. The system, while designed
primarily for occupant protection and egress, can be
used by firefighters to exhaust smoke and allow for
effective fire attack and extinguishment by manual
means.
VM-1 SCS
Smoke control systems, which are not interconnected as
part of an VM-1 fire alarm network panel, constitute a
stand-alone system. The descriptions of components
which follow address a stand-alone smoke control
system, but can also be applied to a FACP function with
the smoke control system components sharing common
inputs and hardware in the VM-1 fire alarm network
panel.
