Expander Cage
The Expander cage is a Primary cage used to collect the monitor outputs from the expansion sets and route
them to the monitors. Figure 36 shows an Expander cage configured for a 2048 camera by 32 monitor
system.

The Expander cage is connected to the last Expansion Set Cage via the EXTERNAL CONTROL IN/ALARM
port. The monitor outputs from each Expansion Set Cage are connected via coaxial cable to the BNC
connectors on Slots 1 through 8. All monitor outputs are provided by the Monitor BNC panel.
Table 17 lists the various configurations and Slot assignments for one to four Expansion sets. Note that the
Interface Board (Figure 34) contained in the Expander cage, has various switch (SW1 and SW3) settings that
are used when expanding the system. There are also jumpers that must be set for camera group pins (PL7
through PL10). All positions and settings are listed in Table 17.
Expander cages can be used for additional camera inputs as well. For example, you might have 3 expansion
sets with 1536 cameras and you want to add an additional 64 cameras. The 3 expansion sets will require 3
slots in the Expander cage, leaving 5 slots open. You can use two of those slots for the 64 additional
cameras.
