9. Faults and Troubleshooting
9.1 Device Fail / Active Faults
If a device on the system is not installed correctly or has been lost from the bus, a device fail will be
present. An example of each fault is as follows:
-
Failure on the panel = 'Control Panel, Wireless Jamming Pnl'
-
Keypad address 3 (0-9 available) failure = 'Device 3, Device Fail Kpd'
-
Tag Readers address 2 (0-5 available) failure = 'Device 2, Device Fail Trd'
-
Remote Input Expanders addresses 0 (0-4 available) = 'ZEM-00, Device Fail ZEM'
-
Remote Output Module address 0 = 'OM-00, Device Fail OM'
If a 'location name' is entered for a device, the location will be displayed on the keypad instead of the
address, such as instead of 'Device 3' the keypad will display 'Entrance Corridor'.

xxx = Kpd
xxx = Trd
xxx = Pnl
485/COMMS LOST
Keypad display is
BLANK
Description
The panel is unable to see the Digi
Modem
There is no telephone or GPRS line
A call to the ARC has failed. NOTE
This is a communication problem,
which is rarely caused by an
equipment fault. Primarily this is
related to the 'hand-shake' and
'kiss-off' frequency set up at the
receiver.
Description
Wired Device on the RS485 bus has
been lost. Each Device is recognised
by its own name, such as:
Output expander = OM
Input expander= ZEM
Keypad = Kpd
Reader = Trd
Control panel = Pnl
This is displayed on a keypad that
has not yet established
communications with the control
panel (End Station)
The keypad address does not match
any keypad enabled in the panel.
Solution
If the modem not present, ensure that the
'Disable Digi' option is set to 'YES' and
'DOWNLOAD MODE' is set to 'NONE' or
'RS232'. If present, but not detected, check
the Digi Modem cable is connected correctly.
a) Make sure the SIM card is plugged in on
the modem/communications module.
b) Make sure the GPRS signal is good enough.
Check that ALL call details are programmed
correctly. Ensure that the signalling format is
correctly set for the ARC receiver.
Solution
Identify the device.
Check that the device is addressed correctly
to match the programming. Check the
connections at the device, and the cabling to
it. If the above are correct, re-boot the
device, followed by a re-boot of the End
Station.
Part of the routine initialisation procedure.
If this persists, check the display at other
keypad(s) to confirm whether the device
failure is at the keypad or complete system
BUS failure. Temporarily install an additional
keypad.
Check the keypad address by pressing and
holding [D] until the security code is
required. Enter '2000' and set the keypad
address. The primary keypad address is set
to [00] by default.
