connected to the LX-Bus circuits.
To continue, press any select key or area. The keypad displays LX-BUS:. Using the digit keys, enter the LX-Bus number, 1
to 5, to test that LX-Bus circuit. The keypad now displays ADDRESS: - . Enter a 2-digit LX-Bus device address and press
CMD. When testing LX-Bus devices, enter only the addresses to which the modules have been set. Press any select key
or area when TEST LX-BUS displays.
A device address is not the same as a zone number. If you are testing 714 or 715 Zone Expander Modules, which each
contain four zones, the device address is the first zone number. When the panel polls a 714 on the LX-Bus, it recognizes
it as a four zone device and does not poll the remaining three zones. The 714 module internally polls the remaining zones
and transmits any status changes to the panel. This greatly reduces the amount of time it takes the panel to poll all LX-
Bus devices.
The keypad next displays TESTING . . . STOP during the device testing. At any time, you can select STOP to end polling.
The panel records the number of no responses from the device. If all polls are received back by the panel correctly, the
keypad displays 00000/65535 FAIL.
If one or more polling attempts fail, the keypad displays * * * * */65535 FAIL with the * representing the number of failed
polling attempts. A display of 65535/65535 FAIL indicates a problem with the interface card or its LX-Bus wiring such
as a bad or broken wire, harness not properly connected, or excessive noise or distance. It can also mean that a zone
number was entered that did not match a device address. Press the Back Arrow key to enter a new device address or
press CMD to exit the TEST LX-BUS.
Zone Finder
The second Diagnostic function is the Zone Finder. Press CMD to display ZONE FINDER. This function
allows you to identify individual zones on devices connected to the LX-Bus of an interface card, the panel, or any zones
on the keypad data bus. To use ZONE FINDER, press any select key or area. The display changes to FAULT ZONE. The
next zone on the system that changes from a normal to an open or shorted state is displayed as ZONE NO: * * *. To
continue, press the Back Arrow key.
Zone State
Press CMD to display the third Diagnostic function: ZONE STATE. This function allows you to enter any zone number and
check its current electrical state (Normal, Open, or Shorted). Press any select key or area. The display changes to ZONE
NUMBER: _ . Enter in the zone number you want to check and press CMD. The panel displays the current state of the
zone as NRML (normal), OPEN, or SHORT.
LX-Bus Status
The fourth Diagnostic function is the LX-BUS STATUS. This function allows the panel to poll all devices connected to the
LX-Bus of an interface card and check for any Overlapped, Missing, or Extra addresses. Below is a description of each
status item:
Overlap - An overlap occurs when one device address is the same as any of the last three zones on another 714 or 715.
The overlap feature cannot determine when two devices have the same address.
Missing - A missing occurs when a zone between 500 and 999 has been programmed in ZONE INFORMATION and no
device with that zone address has been installed on the LX-Bus. To correct the problem, check your zone programming
and zone expansion module addressing.
Extra - A device is installed on the LX-Bus but none of its zones are programmed into the system.
MAC Address
Short for Media Access Control address. This hardware address uniquely identifies each network node. Not to be
confused with an IP address, which is assignable. In the Diagnostics function, the MAC address is the panel on-board
network hardware address. Press any select key or area to display the panel MAC address. Press CMD to view the next
option.
Serial Number
This number is the network communicator serial number. Reference this number for communicator date-of-manufacture,
hardware version, etc. Press any select key or area to display the Serial Number. Press CMD to view the next option.
