Daisy Chaining Multiple DEBCs

Issue

I have multiple DEBCs triggered from the same external source that that need to be tied together. How do I correctly land wiring between the DEBC units?

Solution

  1. For a maintained dry contact (no voltage) land wires on the V Out and Input terminals. All subsequent DEBCs shall be daisy chained via the V Out and Input terminals. Be certain to maintain polarity between the wires. While not always a requirement for functionality, connect the Common terminals together as shown in the diagram below if you hear relays chattering when the DEBC is in an emergency state.
  2. For a maintained wet contact (voltage) land wires on the Input and Common terminals. All subsequent DEBCs shall be daisy chained via the Input and Common terminals. Be certain to maintain polarity between the wires.

For more details, please see the DEBC Installation Guide.

Wet contact is +12VDC  with the positive on INPUT terminal , and Common on COM terminal.
