8. Faults and Troubleshooting
8.1 Device Fail / Active Faults
If a device on the PCX 46 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, Battery Fault”
- Keypad address 3 ( 1-3 available) failure = “Device 3, Device Fail Kpd”
- Tag Readers address 2 (1-3 available) failure = “Device 2, Device Fail Trd”
- Remote Input Expanders addresses 0 (0-4 available) = “RIX-00, Device Fail RIX”
- Remote Output Expanders address 0 = “ROX-00, Device Fail ROX”
If a ‘location name’ is entered for a device, the location will be displayed on the keypad instead of the
address, for example instead of “Device 3” for the Keypad will display “Entrance Corridor”.
8.2 System Faults and Troubleshooting
8.2.1 Communications Faults
Fault Description Solution
MODEM FAULT The panel is unable to see the
Digi Modem
If modem not present, ensure that
“Disable Digi” option is set to ‘YES’ and
“DOWNLOAD MODE” is set to ‘NONE’ or
‘RS232’. If present, but not detected,
check Digi Modem cable is connected
correctly.
LINE FAULT There is no telephone or GSM line Make sure to plug the PSTN modem in
analogue convention type telephone line.
Make sure the SIM card is plugged on the
modem
Make sure the GSM signal is good
enough.
CALL FAIL TO
ARC
Call to ARC has failed. NOTE This
is a communication problem,
which is rarely caused by an
equipment fault. Mostly can be
related to hand shake and kiss off
frequency set up at receiver.
Check ALL call details are programmed
correctly. Ensure signalling format is
correctly set for ARC receiver.
ATE LINE
FAULT
PSTN Line Fault signalled by
device using ATE pins on End
Station.
Only operative if Site Option "ATE Input"
is set to 'UK STU' or 'ATE Line Fault.'
Check voltage on input pin– if +5/12
volts, device connected is showing fault.
Note: 'Line Fault' timer operative
ATE Call
Fail 100
Call to ARC from device using
End Station ATE pins has failed.
Only operative if Site Option "ATE Input"
is set to 'UK STU.' Check voltage on input
– if +5/12 volts, device connected is
showing fault
ATSF 1
Path 100
ATSF all
path 100
Signalling equipment has
failed to signal on one of its
paths or both of its paths
The control panel will automatically signal
a test on ATE output 10 – if the signalling
equipment has still failed the error
message will be displayed again. If not
everything
will return to normal.
8.2.2 RS485 Bus Problems
Fault Description Solution
DEVICE FAIL xxx
xxx = ROX
xxx = RIX
xxx = Kpd
xxx = Trd
xxx = Pnl
Wired Device on the RS485 bus
has been lost. Each Device is
recognised by its own name such
as:
Output expander = ROX
Input expander= RIX
Identify device.
Check device addressed correctly to
match programming. Check connections
at device, and cabling to it. If above
correct, re-boot device, followed by re-
boot of End Station.
