The DCS100, 200, 240 and DB150 use several beeps and clicks that can be used as diagnostic tools that will help you debug a number of error conditions.
DCS100/200 Audible Sounds
1 Beep DCS100/200 has powered on successfully or has sent a programming command.
3 Beeps A loco address has been "purged" due to non-use. This is informational only and is normal.
4 Beeps Booster short circuit shutdown. Fault Alarm.
6 Beeps Command station already present in system. When two command stations are operating on the same system, you may experience unexpected results.
7 Beeps DCS100/200 CMOS battery low condition. Battery should be replaced as soon as possible. See Section 8.0 for CMOS battery replacement instructions.
8 Beeps Memory ECC/checksum fail. This indicates that the local CMOS memory has been corrupted and was reset automatically. This is a technical diagnostic.
9 Beeps DCS100/200 transmit failure, there is a device blocking proper message action on LocoNet.
16 Beeps Software timeout failure. No action is required, the unit will resume operation.
Continuous Soft clicks Low input power supply voltage. If the DCS100/200 input voltage falls below about 9.5V DC or 8V AC while operating, the DCS100 will emit a series of continuous soft clicks until the low voltage condition is corrected.
DB150 Audible Sounds
1 Beep DB150 has powered on successfully or has sent a programming command.
3 Beeps A loco address has been “purged” due to non-use. This is informational only and is normal.
5 Beeps Booster short circuit shutdown. Fault Alarm.
6 Beeps DB150 has been powered up as a command station in a system that aleady has an active command station.
9 Beeps DB150 transmit failure, there is a device blocking proper message action on LocoNet.
16 Beeps Software timeout failure. No action is required, the unit will resume operation.
Variable Clicks OPSw 41 is Closed. Diagnostic clicks will sound when a valid LocoNet command is received.
DCS240 Audible Sounds
1 Short Beep Diagnostic Beep when OPSW41='c', LocoNet commands incoming. In EZ routes mode, indicates a switch has been saved. During operation, the DCS240 has recovered from a fault

8 Short Beeps Route Error, Maximum switch commands issued
1 Long Beep In EZ Routes, initial Route ID saved
2 Long Beeps In EZ Routes, route saved and exit EZ Routes
3 Long Beeps When pressing the LocoReset Button, all loco addresses purged from the system. LocoPurged from system
4 Long Beeps Input Voltage is out of range 13.8V to 24 V DC
DCS210 & DCS210+ Audible Sounds
Continuous short beeps Voltage Trim Mode, selection is in range.
1 Short Beep Diagnostic Beep when OpSw41 = c, LocoNet commands incoming. In EZ routes mode indicates a switch has been saved. During operation, DCS210/DCS210+ has recovered from a fault
2 Short Beeps Initial DCS210 Power on or DCS210 had purged a loco address
3 Short Beeps. Entered quick routes mode
4 short Beeps. Booster short circuit shutdown
5 Short Beeps. Route Error, looping route
8 Short Beeps. Route Error, Maximum switch commands issued
1 Long Beep In EZ routes, initial Route ID saved
2 Long Beeps. In EZ routes, route saved and exit EZ Routes
3 Long Beeps When pressing the Loco Reset Button, all loco addresses purged from the system
4 Long Beeps Input Voltage is out of the range 13.8V to 24V DC
10 Long Beeps. DCS210 has detected another Command Station on LocoNet and has turned off track power
