12.7 Matrix Zone Expanders

12.7.1 Local Plug-On 8 Zone Expander

The MX-16 expands the system by a further 8 DEOL zones (16 if zone doubling is used).
NOTE: The Matrix 832/832+ cannot support more than 16 DEOL zones, and the Matrix 424 no more
than 12, so if a local expander is fitted remote expanders will be ignored; conversely if a remote
expander is present the local expander will be ignored.
