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:
D E V I C E F A I L 1 0 0 = E n d S t a t i o n
D E V I C E F A I L 2 0 0 = K e y p a d
D E V I C E F A I L 3 0 0 = T a g R e a d e r / D o o r S t a t i o n / R I X 2
D E V I C E F A I L 4 0 0 = R e m o t e I n p u t E x p a n d e r
D E V I C E F A I L 5 0 0 = R e m o t e O u t p u t E x p a n d e r
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.

COMMUNICATION FAULTS
Solution
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.
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".
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.
Only operative if "DOWNLOAD BY MODEM" selected
OR "DISABLE DIGI/SMS" is set to 'NO'

'STU' or 'Digicom.' Check voltage on input pin – if +5/12
volts, device connected is showing fault.
