the main PCB in the control unit. The table below summarises the number

CCL Connections
Figures 18 and 19 shows how to connect four-wire CCL zones with common
and individual tampers. The control unit provides enough connectors for eight
CCL zones. If you wish to connect more, you must fit one or more hardwired
expanders (see "Connecting Expanders" on page 32).
