  • Monitoring up to 236 dampers with expansion modules
  • Adjustable function test
  • Up to 20 sections
  • Three thread network minimize wiring.
  • 24 VAC
  • Can be connected and communicate with a master system via modbus
  • Can be connected to an Ethernet (TCP/IP)

Function

The RCTC is a self-monitoring control panel used as a central unit for RCTU damper modules. 59 RCTU modules can be connected to an RCTC. For larger systems, an expansion unit is used – the R30. It can handle an additional 59 dampers per unit. The RCTC can handle up to three R30 units, which means that the maximum number of dampers is 236.

Communications between the RCTC and connected RCTU modules are via a three-wire cable with free configuration (free topology) in linear, branched or star networks. The RCTC has an integrated clock with a battery on which the time for manoeuvring can be set. In the event of communications faults, the RCTU damper module switches to alarm operation. Operating status is indicated at each RCTU but can also be read on the RCTC.

The RCTC has a display and keypad for checking current status, making settings, conducting function tests and resetting smoke detectors. The modules can sectionalised for example.
