What is the auxiliary output AUX on 01401 used for?

It can be used to:

  • supply power to the Burglar alarm system Back-Up unit if present:
  • supply power to the 20550 and touch monitors in general (e.g. 21511, 20511.1, 21554, etc.) through the V + V - terminals present in these products, in case the burglar alarm system is not installed.

It should be noted that the maximum deliverable rated current (1280 mA) can be calculated by summing up the delivery of the two AUX + BUS outputs.
