ECP Zone Expander (2–44+ Only)
This is an expander for use on panels that use the ECP communication Bus. Up to three zone expanders can
be fitted to the Galaxy 2–44+ panel. Each expander gives 8 extra hardwired zones and four programmable
outputs. An alternative expander gives four extra hardwired zones and no outputs.
Figure 22. Zone Expander Outputs
Zone Expander Outputs
The four outputs are switched 0V (0V active). Without the jumper they will float in the ‘OFF’ state (see
Figure 23). They can apply a +12V signal, if required, by fitting the appropriate pull-up jumper supplied (see
Figure 24). (This is typically required for activating comms devices). All devices wired to the outputs must
have their negative terminals wired to the switched output, and their positive terminals wired to the + 12V
output.
