Control unit RCDU2

The RCDU2 is an encapsulated microprocessor-based, intelligent, self-monitoring control unit for connecting up to 2 dampers and 2 detectors.

Quick facts

  • Up to 2 dampers and 2 smoke detectors
  • Indicators for each individual damper
  • Optional external incoming alarm
  • Alternating relay contacts for both main alarm and dirty detector
  • Integrated transformer from 230 V to 24 V for powering actuators

Function

The RCDU2 is an encapsulated microprocessor-based, intelligent, self-monitoring control unit for connecting up to 2 dampers and 2 detectors.

The RCDU2 can act as an independent control unit and perform automatic function tests every 48 hours after power up/resetting. Function tests can also be initiated by an external switch. The RCDU2 has electronic circuits that automatically connect outputs with connected damper actuators.

The detector input features an electronic short circuit fuse. All connected dampers enter the alarm position in the event of a short circuit or a break in one of the detector loops. The RCDU2 can be set to alarm operation mode by an external incoming alarm.
