A Guide to the DC2 Control Panel

In this FAQ guide, we'll explore various aspects of the DC2, including programming transmitters, troubleshooting, and maximising its functionalities to optimise your access control operations. 


Here's a quick overview of the DC2's key specifications:


Supply Voltage: Operating at 230VAC 

Frequency: 50 Hz.

Max motor power: 1150W

Outputs: Equipped with motor relay contacts for optimal functionality, including 3x NO relay contacts at 230V/5A and 2x NO relay contacts at 230V/2A. Additionally, it provides one unregulated supply voltage output at 24V DC with a maximum current of 200mA.

Wiring Capacity: Supports wiring up to 1.5 mm²

Operating Temperature: Capable of operating within a temperature range of -10°C to +55°C



What are the dipswitch configurations on the DC2?


The DC2 features four banks of dipswitches:


  • Prog2/Dip1: Switch 1 for keypad programming, Switch 5 for handheld transmitter programming.

  • Prog1/Dip2: Switch 1 selects optical or resistive safety edge, Switch 3 for extended run time.

  • RT/Dip3: Options for runtime between 8 and 193 seconds.

  • CT/Dip4: Options for autoclose time between 5 and 129 seconds.


How do I program transmitters with the DC2?


  • Turn off the main power, plug in the radio receiver, and restore mains power.

  • To program, turn on switch 5 (PRog2); the display will show zero.

  • Press the top yellow button on your handheld fob; the panel will beep, and the display will show one.

  • Each additional fob will increase the number on the display (up to twenty transmitters).

  • After programming all transmitters, turn off dipswitch 5.

  • Test the transmitters by pressing once for impulse up, the next press to stop the door, and the last press for impulse down.


Note: These transmitters only work with impulse operation, so ensure both safety forms are programmed for the door to operate.


Optionally, use an external 24V DC radio receiver for impulse up and dead man down operations.


How do I delete transmitters with the DC2 panel?


  • With the DC2 panel, you can delete transmitters individually without a master clear. We recommend labelling each transmitter to match its number on the panel for easy identification and deletion.

  • Turn on dipswitch 5 (PRog2); it will display the last programmed transmitter.

  • Press the program button below the display to the right to select the transmitter you want to delete.

  • Hold down the program button; the panel will emit a double beep, indicating the deletion of that transmitter.

  • Once you've deleted the desired transmitters, turn off dipswitch 5.


What does the DC2 Diagnostic Display indicate?


  • The DC2 features a digital display for door status and diagnostics.

  • A blank display typically indicates a lack of power to the board.

  • Upon initial power-up, the display will show 3 horizontal lines, indicating readiness for operation.


Fault Codes:


  • Fault Code 1: Stop circuit fault.

  • Fault Code 2: Safety edge activation.

  • Fault Code 3: Photocell activation.

  • Fault Code 4: Power supply issue - instability or a stuck relay on the board.

  • Fault code 5: Run time error - check the position of dip switches

  • Fault code 6: pull-in protection activated - check alignment of light barrier

  • Fault code 7:Input IN short circuit - check installation or DIP switches

  • Fault code 8: RAM/ROM - test failed - Replace circuit board

  • Fault code 9:Slack rope switch: Check wiring and position of the switch
