tors on the back of the annunciator. Set DIP switch SW1 for the desired
options. Refer to Figure 1-3 on page 12.
Carefully insert the FDU-80 into the three-gang electrical box P/N:

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.
