7.5 Fan Damper Control Display Module (FDX-008W/WKI)
There are two models of the Fan Damper Control Display modules available. 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 a FX-2000 Fire Alarm Control Panel.

7.5.1 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.
7.5.2 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. 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), the ON LED will flash. The TRBL (trouble) LED will illuminate
