15.1 LX-Bus/AX-Bus Headers
XR Series control panels are capable of providing zone, output, and access control expansion by connecting hardware
modules to the AX/LX-Bus headers on the control panel. XR150 panels are manufactured with one LX-Bus header
labeled LX500. AX-Bus operation does not apply to XR150 panels. XR550 panels are manufactured with ve AX/LX-Bus
headers labeled LX500-LX900. Application determines if a header works in AX-Bus or LX-Bus operation.
LX-Bus (XR150/XR550)
LX-Bus operation is compatible with hardwired zone and output
expanders. Each LX-Bus represents 100 addresses. An LX-Bus address
provides one zone and one output of expansion.
• LX500, provides zones/outputs 500-599 (XR150, XR550).
• LX600, provides zones/outputs 600-699 (XR550 only).
• LX700, provides zones/outputs 700-799 (XR550 only).
• LX800, provides zones/outputs 800-899 (XR550 only).
• LX900, provides zones/outputs 900-999 (XR550 only).
AX-Bus (XR550 V111 or higher):
AX-Bus operation is compatible only with XR550 control panels and
DMP Model 734 Wiegand Interface door access modules. The 734
provides one Form-C relay output and four expansion zones. AX-Bus operation is not compatible with addressable
zone and output expanders. Each AX-Bus represents predetermined addresses for 734 operation: 16 addresses for 734
door relay outputs, and 64 addresses for 734 expansion zones.

15.2 Device Addressing
Addressable expanders and door controllers identify themselves to the control panel by their programmed address,
which allows the panel to uniquely identify devices. An addressable device’s address determines which numbers
the zones, outputs and door controllers will be assigned in programming. Refer to the device’s installation guide for
addressing information.
