Expanders, Keypads and subsequent Zones may be configured, located and
monitored, with the steps provided in this section. X-BUS settings such as type,
communication times and retries are also accessed within this menu.
Rotary switches on the Expanders provide functionality allowing the Engineer to
define each device’s numbered identification. Fig. 17 shows each rotary switch with
an arrow symbol pointing to a number for identification (ie. 3, 8). The right switch is
the first unit digit and the left switch is the 10s digit. The Expander in Fig. 17 is
identified as 38.

Each Keypad and Expander is to be uniquely addressed. In this manual
configuration, the system automatically allocates zones to each Expander. For this
reason, devices with no zones, such as 8 Output Expanders should be addressed
last.
NOTE
Automatically-Addressed Expanders are not supported by the SPC4000.
