The FSCS Controls
The FSCS that was used in Chapter 5 will be used as an example FSCS
in this chapter. Your FSCS will not look identical to this one, but it will
be capable of performing the same functions.
The MASTER KEY
The MASTER KEY is an electrical keyswitch on the FSCS panel.
• When the MASTER KEY is turned OFF, the audible alarm is enabled
and the FSCS manual overrides are disabled.
• When the MASTER KEY is turned ON, the audible alarm is silenced
and the FSCS manual overrides are functional.
The MASTER KEY can only be removed when it is in the OFF position.
This ensures that the system is left in the normal operating mode.
Consult the local authority having jurisdiction to determine who should
receive one of the MASTER KEYs.
Fan Overrides and Indicators
Each fan that has a capacity in excess of 2000 cfm will be provided with
Override capabilities, a STATUS indicator, and a FAIL indicator on the
FSCS.
Figure 6-1 shows an example of the FSCS controls for a fan.
