Fan Damper Control Display Module ( FDX-008W( KI ) )
The FDX-008W provides switch control and LED indication of 8 fan damper zones. The FDX-008WKI provides
switch control of 7 fan damper zones with the eighth zone activated by keyswitch. LED indication is provided for all
8 fan damper zones on the FDX-008WKI. Both the FDX-008W and the FDX-008WKI are used in conjunction with
an FX-2000N Fire Alarm Control Panel.

Fan Damper Operation
The FDX-008W Fan Damper Control Display module has eight configurable output circuits, each with a three
position switch. The FDX-008WKI operates in the same manner as the FDX-008W except zone 8 is controlled by a
remote keyswitch. Each switch has an ON and OFF position, plus an AUTO position. If the switch is placed in the
AUTO position, the white AUTO LED will illuminate steady and the output will activate as programmed or
configured. The output can be manually turned ON or OFF by placing the switch in the ON or OFF position,
respectively.
Basically each switch can be configured to operate multiple fans or dampers. For each switch, there are 3
operations provided; outputs to turn ON, same outputs to turn OFF and inputs to bypass.
An example of the most common use of the FDX-008W or FDX-008WKI Fan Damper Control Display module is to
operate exhaust fans and confirm fan operation (via monitor modules). See FDX-008W Block Diagram on the next
page for a block diagram of fan and monitor set up.
Example
As shown in the figure to the right, Parking Garage #1 has 3 exhaust fans. The three
position switch is configured to operate (to turn ON) fans 1, 2 and 3 in stairwell #1. The
switch is set in the AUTO position (white AUTO LED on steady). Upon activation (via
alarm or some other programmed trigger) with the switch in AUTO, the 3 fans (1,2, and
3) in stairwell #1 are turned ON automatically. Monitor modules in the Parking Garage
#1 detect that all 3 fans are operating, therefore the ON LED will illuminate steadily. If
one of the fans did not turn ON (due to malfunction), both the ON and OFF LEDs will
flash at the slow trouble rate. The TRBL (trouble) LED will illuminate steady amber
based on feedback from the monitor module that one or more of the fans is not working.
AUTO LED shows steady for switch in AUTO position.
ON LED shows steady for all outputs operating and confirmed.
OFF LED shows steady for all outputs NOT operating and confirmed.
TRBL LED shows steady for one or more outputs NOT operating and confirmed.
Note: A bypass function always has priority, so that if a circuit is bypassed by moving the switch manually
or by loop bypass (FX-2000N Fire Alarm Panel), no other action will operate this switch other than
again moving the switch manually or by un-bypassing the loop.
