Setting the Station’s Address
Each master station in the system requires a unique address. If two master stations have the same address,
data collision will occur when communicating with the merge/isolate cabinet, resulting in a fault condition.
The master station addresses must be set in sequence starting at 1. Do not skip any numbers when
assigning addresses.
The I/O control board is located inside the desktop subset. This determines the station address and also
controls the station’s zone and alarm selection features by scanning the switches and then transmitting the
selection to the merge/isolate cabinet over a data line. There are several switches and jumpers on the I/O
board that must be set correctly for the station to operate correctly. Refer to Figure 1 below for I/O
controller board outline and switch locations.

Switches S1 and S2
S1 and S2 are hexadecimal switches that are used to set the I/O board’s address. If the system contains
more than one master station, each station’s I/O board must be set with a different sequential address
starting with 01. Switch S2 sets the first digit and switch S1 sets the second digit.
