Set the 734 Address
To set the 734 address, move the DIP switches on the PCB to the appropriate positions. See the following sections, Figure 11,
and Table 2 to determine how to set Keypad Bus or AX-Bus addresses.
Keypad Bus Addresses Explained
Each Keypad Bus address can accommodate one door output and four expansion zones. A 734 with an address of 2 on
the Keypad Bus would represent door 2 and zones 21-24. A 734 with a keypad address of 14 would represent door 14 and
zones 141-144.
AX‑Bus Addresses Explained
XR550 panels are capable of access control expansion using any of the five AX/LX-Bus headers (AX/LX500, 600,
700, 800, and 900). An AX-Bus address can accommodate one door output and one expansion zone. Because
the 734 has a built-in four-zone expander, three extra zones will be mapped to the 734 automatically.
A 734 with an address of 1 on AX500 would represent door 501 and zones 501-504. A 734 with an address of 2
on AX500 would represent door 505 and zones 505-508. A 734 with an address of 1 on AX700 would represent
door 701 and zones 701-704.
Note:
Hardwired zone expanders and modules do not communicate on an AX-Bus. Doors connected to
the AX-Bus do not have programmable device or communication types and do not have assignable display
areas.
