Probable Cause
An open circuit in wiring from the
ATM-L's "Lamp Test" input terminal to
the associated annunciator's lamp-
test switch. ATM-L address is Addr.
A communications fault between the
main printed circuit board and the
RDCM at address Addr.
The control unit has not been set up
to expect the RDCM at RDCM RS-485
circuit address Addr.
A loss of 24 Vdc power at TB1,
Terminals 1 and 2 or an open circuit
in the RDCM's monitoring circuit from
TB1, Terminals 3 and 4 to the
normally-closed trouble contacts of
its associated remote power supply
Corrective Action
• Refer to ATM Installation Manual,
• Look for discontinuity in wiring to
• Check for missing 10k end-of-line
• Check the RS-485 wiring from
• Check for a discontinuity in the RS-
• Troubleshoot wiring to RDCM TB1,
• Check for 24 Vdc power at RDCM
• Ensure that the RDCM's RS-485
• Ensure that the RDCM Address
• Check for duplicate addressed
• Register the RDCM if part of system
• De-register the RDCM if not part of
• Check the 24 Vdc power (TB1,
• Ensure that the RDCM Address
