Error Number
mAs calibration error
Error Code System Message
MAS CAL ERROR 1 / 4
Question
How does AMX-Series mAs calibration work?
Short Answer
The system injects a known current into the mA measuring circuit and compares counted pulses to expected mAs response.
Possible Causes
mAs VCO/counter/calibration fault.
Troubleshooting Steps
Verify the calibration source/current, mA measuring circuit, VCO/counter response and CPU data before repeating calibration.
Parts Areas to Check
mA measurement circuit; VCO; CPU counter

Error Number
system is switched from an “OFF” state to “ON” state
Error Code System Message
Question
How do I troubleshoot this AMX-4 Series issue: When the AMX4/AMX4+ system is switched from an “OFF” state to “ON” state, a peak inrush current spike greater than the 10A rating of the K215 relay contacts was observed. This spike has the potential to weld the contacts?
Short Answer
The solution is to replace the CONDOR power supply (Vendor part# MDSP1733, GE part# 2318476) with the modified CONDOR/SL power supply (Vendor part# MDSP1733A, Orderable GE part# 2366118). The new supply has an inrush current profile that is much smaller than the existing supply. Refer to Service Note 30004.
Possible Causes
Problem: When the AMX4/AMX4+ system is switched from an “OFF” state to “ON” state, a peak inrush current spike greater than the 10A rating of the K215 relay contacts was observed. This spike has the potential to weld the contacts of the K215 relay. This welding action causes the system to remain in the “ON “state even after switching the state to “OFF.”

AC not present
Error Code System Message
Question
What does the AC Present diagnostic test on the Brivo XR285amx?
Short Answer
It verifies that the system recognizes when the AC power plug is connected to the receptacle.
Possible Causes
AC-detect circuit issue; plug/receptacle problem; power-control communication fault.
Troubleshooting Steps
Connect AC power and run AC Present. If the system does not recognize AC, verify the physical connection and then troubleshoot the power-control detection path.

Error Number
BDM mismatch
Error Code System Message
Question
What should I do when the Brivo XR285amx shows a BDM Mismatch screen?
Short Answer
For a normally operating system with no parts replaced, select RESTORE. If parts were replaced, follow the replacement-finalization instructions for that component.
Possible Causes
Configuration fingerprint or firmware mismatch detected during power-up.
Troubleshooting Steps
Confirm whether any intelligent board or generator component was replaced. If no parts were changed, select RESTORE. If a part was replaced, use the System Manual finalization procedure for the correct Restore/Cancel selection.
