23.1 False Alarm Reduction
System Recently Armed report
The System Recently Armed report (S78) is sent to the receiver when a burglary zone goes into alarm
within two minutes of the system being armed.
23.2 Diagnostics function
The XR500 Series Canadian panel contains a Diagnostics function that allows you to test the communication
integrity of the LX-Bus™, identify individual zones, and also display the present electrical state of any
zone. The Diagnostics function also allows you to test the integrity of the cellular communication, cellular
signal, and email communication. To use Diagnostics, reset the panel, enter the Diagnostics code 2313
(DIAG), and press COMMAND.
Test LX-Bus
The first Diagnostic function you displayed is:
TEST LX-BUS. This function allows you to test the ability of
the 481, 462N, 462P, 463C, 463G and 472 Interface Cards to communicate with zone and output expander
modules connected to their LX-Bus circuits.
To continue, press any top row Select key. 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 COMMAND. When testing LX-Bus devices, enter only the addresses to
which the modules have been set.
Important Note: 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 COMMAND to exit the TEST LX-BUS.
Zone Finder
The second Diagnostic function is the Zone Finder. Press COMMAND 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 top row Select key. 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 the COMMAND 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. The display changes to ZONE NUMBER: _ . Enter in the zone number you want to check and press
COMMAND. 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.
Example: Model 714 Address 00 = Zones 500 501 502 503, and the Model 711 Address 02 = Zone 502.
Zone 502 would report as an Overlap because both the 714 and 711 have devices set to 502.
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 top row Select key to display the panel MAC address.
