Resetting the FSCS
The correlation inputs and outputs shown below can be
used to create a correlation that demonstrates how to
program a switch on the FSCS to perform a system
reset.
Name:
RESET
Inputs:
Switch, Cab01_Ann01_Exp01_SW01
Outputs:
ENABLE, Low, Both, All_Cabinets
Weekly self-testing
The correlation inputs and outputs shown below can be
used to create a correlation that demonstrates how to
program an automatic weekly self-test for a dedicated
smoke control systems (i.e. stairwell pressurization
systems).
Name:
WEEKLY SELF TEST 1
Inputs:
Timecontrol, FAN_TEST_ZONE_W
Outputs:
ON, High, Both, ZONE_W_SUPPLY_DAMPER_OPEN
OFF, Low, Both, ZONE_W_SUPPLY_DAMPER_AUTO
STEADY, Low, Both,
ZONE_W_SUPPLY_DAMPER_ON_LED
DELAY, Low, Activation, 60 seconds
ON, High, Both, ZONE_W_SUPPLY_FAN_ON
OFF, High, Both, ZONE_W_SUPPLY_FAN_AUTO
STEADY, Low, Both,
