Description

Emergency order telegraph system for communication
between the bridge and engine room

The emergency order telegraph system allows the bridge and engine room to communicate with one another quickly and reliably in case of an emergency. An order is transmitted from the bridge to the engine room at the touch of a button, where it is then signalled visually and acoustically on one or more telegraphs. The staff in the engine room need to acknowledge the order to make the visual and acoustic alarm stop.

Up to 12 telegraphs can be integrated in one system. Each telegraph is equipped with 11 illuminated order buttons and an integrated buzzer. Furthermore, other functions, such as changing over between two telegraph systems, "wrong-way alarm" or the activation of external alarm indicators, can be integrated, too.

Application

The emergency order telegraph system is flexible and scalable, meaning it is suitable for small applications with just two devices (e.g. bridge and in engine room) right up to large installations with several systems (multiple bridges and engine rooms). Different device versions are available for use on the bridge, aft bridge or in the engine control room.

  • Emergency communication system between bridge and engine room
  • Up to 12 telegraphs in one system
  • Different device versions for bridge, aft bridge and engine room
  • Illuminated order buttons with visual order signalling and differently coloured lights for order statuses
  • Integrated buzzer for acoustic order signalling
  • Operating status indicator and integrated self-monitoring function
  • Dimmer function for bridge device
  • 2 binary, galvanically isolated inputs
  • 4 potential-free relay outputs
  • Interface with VDR system
  • Lamp test
