Figure 14. Connecting a 9954
When fitting a 9954 Expander make sure you place the jumper link on the
expander in the correct position to select either four-wire CC, or two-wire FSL
or EOL.
Note: Make sure that the control unit and the expander use the same wiring method
for zones. If you select a different wiring method for zones on the expander
then the control unit may not report tampers correctly.
