The FX-4003-12N or FX-4017-12N Main Chassis come pre-assembled with a main fire alarm
board. Install the adder modules of different types as shown in the following diagrams.
Figure 6 Module Mounting Locations View #1
Notes: For many adder modules to enable communication from the main module to all of the
adder modules, it is necessary to add a continuity jumper on the last adder module in a
chain (see the appropriate module settings section to verify the location of the continuity
jumper on a particular circuit adder module). Only the last circuit adder module should
have a jumper plug on its continuity jumper; all others must be left without a jumper plug.
