ADDRESSING THE 734N
Keypad Bus Addresses
DMP XR550 Series panels use keypad bus addresses 1 through 16. XR150 Series panels can only use
keypad bus addresses 1 through 8. Each keypad bus address can accommodate 1 door output and 4
expansion zones. A 734N with an address of 2 on the keypad bus would represent Door 2 and zones
21-24. A 734N with a keypad address of 14 would represent Door 14 and zones 141-144.
AX-Bus Addresses (XR550 only)
DMP 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 1 door output and 1
expansion zone. Because the 734N has a built-in 4-zone expander, 3 extra zones must be mapped to
the 734. A 734N with an address of 501 on AX500 would represent Door 501 and zones 501-504. A
734N with an address of 505 on AX500 would represent Door 505 and zones 505-508. A 734N with
an address of 701 on AX700 would represent Door 701 and zones 701-704.
Note: Hardwired zone expanders and addressable points and modules do not communicate on
an AX-Bus. AX-Bus doors do not have programmable device or communication types and do
not have assignable display areas.
