15.1 LX-Bus HeadersLX-Bus/AX-Bus Headers
XR150INT/XR550INT Series 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. XR150INT panels are
manufactured with one LX-Bus header labeled LX500. AX-Bus operation does not apply to XR150INT panels.
XR550INT panels are manufactured with five AX/LX-Bus headers labeled LX500-LX900. Application determines
if a header works in AX-Bus or LX-Bus operation.
LX-Bus (XR150INT/XR550INT)
There are five LX-Bus headers near the bottom of the
XR150INT/XR550INT panel:
• LX500 provides zones 500-599 (all panels).
• LX600 provides zones 600-699 (XR550INT only).
• LX700 provides zones 700-799 (XR550INT only).
• LX800 provides zones 800-899 (XR550INT only).
• LX900 provides zones 900-999 (XR550INT only).
AX-Bus (XR550INT V111 or higher):
AX-Bus operation is compatible only with XR550INT control
panels and DMP Model 734INT Wiegand Interface door access modules. The 734INT 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 734INT operation: 16 addresses for 734INT
door relay outputs, and 64 addresses for 734INT expansion zones.

15.2 LX-Bus/AX-Bus LEDs
The two LEDs, located above each LX-Bus header, indicate data transmission and receipt. The left LED
flashes green to indicate the panel is transmitting LX-Bus data. The right LED flashes yellow to indicate the
panel is receiving LX-Bus data.
