The Fundementals of Smoke Control
The indicator lights on the FSCS provide information about the
functioning of the system. The following colors should be used for the
FSCS indicators:
• Green—Fans and other equipment are running or dampers are open.
• Yellow—Dampers are in the closed position.
• Orange or Amber—The equipment has failed.
• Red—A fire has been detected in the area.
The FSCS has a lamp test button that turns on all the panel's lights. Use
this button regularly to make sure none of the lights has burned out.
The FSCS gets information on the status of the smoke control system's
equipment from proof monitors on the equipment itself. Each fan that
has a capacity over 2,000 cfm capacity should be mounted with a
pressure monitor. Smoke dampers should be fitted with end-range
microswitches to indicate that they are fully opened or fully closed.
All of the failure lights on the FSCS (the orange or amber ones)
represent the state of the equipment as determined by the proof sensors.
The failure light comes on if the piece of equipment is not in the state its
control is set for within its trouble indication time. This time is 60
seconds for a fan and 75 seconds for a damper. If, within that time, the
proof sensors do not report that the piece of equipment has responded to
the control system's command, the FSCS indicates that the piece of
equipment has failed.
