Size Settings
The rotary decimal SIZE switch on the NIB sets the capacity of the System 5000.
The size corresponds to the number of slave circuits that the master control panel
will monitor as individual points. The SIZE of the System 5000 is usually eight times
the number of modules installed, including the CPU.
Note: All connections shown are
power limited
