Semi-flush Mount Backbox
4.2.1 Mounting in SBB-3 Three Gang Electrical Box
Remove the plug-in terminal blocks from the
illustrated in Figure 5.1 on page 15 through Figure 5.5 on page 16. Plug the terminal blocks back into the P2 and P1 connectors on the back of
the annunciator. Set DIP switch SW1 for the desired options. Refer to Figure 2.2 on page 9.
Carefully insert the FDU-80 into the three-gang electrical box P/N: 10103 or three electrical boxes ganged together and attach it using
the four mounting holes on the FDU-80 flange and the four screws provided for this purpose. Replace the trim ring and secure with the
two screws which were previously loosened. Adjust the plastic trim ring to the surface of the wall before tightening the screws. Do not
overtighten.

The FDU-80 can be semi-flush
mounted in a three-gang electrical
box, P/N 10103 or equivalent, with a
minimum depth of 2.1875". The
FDU-80 can also be mounted in
three gangable electrical switch
boxes connected together as
illustrated in Figure 4.4 on page 13.
Important! When installing
conduit in a 3-gang electrical box,
use knockouts on the top or
bottom. Installing conduit on the
sides or back of some boxes may
interfere with mounting of the
FDU-80 in the box.
4.2.2 Mounting in Three Electrical Boxes Ganged Together
Remove the plug-in terminal blocks from the FDU-80 circuit board. Connect the EIA-485 and power wiring into the terminal block posi-
tions illustrated in Figure 5.1 on page 15 through Figure 5.5 on page 16. Plug the terminal blocks back into the P2 and P1 connectors on
the back of the annunciator. Set DIP switch SW1 for the desired options. Refer to Figure 2.2 on page 9.
Carefully insert the FDU-80 into the three electrical boxes ganged together and attach it using the four mounting holes on the FDU-80
flange and the four screws provided for this purpose. Replace the trim ring and secure with the two screws which were previously loos-
ened. Adjust the plastic trim ring to the surface of the wall before tightening the screws. Do not overtighten.

or bottom. Installing conduit on
the sides or back of some boxes
may interfere with mounting of
the FDU-80 in the box.
