Status Indicators
The actual status of the smoke control equipment must be clearly
indicated on the FSCS by the use of visual indicators with appropriate
legends.
Fans must have a single indicator that turns on when the fan’s
differential pressure “proof sensor” indicates that the fan is operating.
Dampers must have 2 indicators: one that turns on when the damper’s
end-limit “proof sensor” indicates that the damper is closed, and one that
turns on when the damper’s other end-limit “proof sensor” indicates that
the damper is open. Both indicators should be off when the damper is
positioned between the open and closed positions.
The FSCS should provide a status indicator for each zone that signals
whether or not the zone is in an alarm condition.
The FSCS should provide status indicators for each piece of equipment
that signals when there has been an equipment failure. For instance, if
the fans do not turn on within 60 seconds, or the dampers do not reach
the desired position within 75 seconds, the fault indicator should turn on.
Table 2-4 lists the status indicator colors that must be used on the FSCS
