APPENDIX A: FAULTS
Device Fail
If a device on the PCX system is not installed correctly or has lost its communication with the
panel, “DEVICE FAIL” will be shown on the LCD keypad followed by a 3-figure device code. The
first digit identifies each type of device:
DEVICE FAIL 100 = End Station
DEVICE FAIL 200 = Keypad
DEVICE FAIL 300 = Tag Reader / Door Station / RIX2
DEVICE FAIL 400 = Remote Input Expander
DEVICE FAIL 500 = Remote Output Expander
The digits after refer to that devices address, for example:
DEVICE FAIL 401 = means that the Remote Input Expander addressed as “01” has a problem.
Fault Indications
COMMUNICATION FAULTS
Fault Description Solution
MODEM
FAULT
End Station unable to
communicate with 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 is
inserted correctly and complete initialisation by pressing
End Station ‘RESET’ button for 2 seconds.
DIGI FAIL
COMM
Call to ARC from Digi Modem
DigiModem has failed.
Note: This is a
communication problem,
which is rarely caused by
an equipment fault.
Check ALL call details are programmed correctly.
Ensure signalling format is correctly set for ARC
receiver.
If only one call number programmed, ensure “STOP ON
SUCCESS” = ‘YES’ and “TRY SAME” is selected – NOT
“TRY NEXT”.
PHC TEST
FAIL
Unable to communicate with
Pyronix Host Computer.
Note: This would also
result if the telephone line
had premium rate calls
blocked.
Ensure Digi is enabled, and at least one SMS call is
correctly programmed.
Check that ordinary phone on same line connects to
PHC and modem tones heard - if not, problem is PSTN
– NOT equipment.
De-program SMS content types for each call, exit
Engineer menu, press RESTART button, and retry PHC
test from Manager menu.
