Operation
How does the Inelteh emergency telegraph system work?
As soon as the main communication between bridge and engine room is disrupted, such as during a power failure or during a calamity or emergency, it is possible to fall back on an emergency system for this communication, the emergency telegraph. Inelteh provides a clear emergency telegraph system, on which clear instructions can be given from the bridge, and then confirmed from the engine room.
Any command from the engine room, relating to a change in the ship’s propulsion, is sent from panel EET1-Tx in that case, using a rotary switch. That command is then received in the engine room, on unit EET1-Rx. From the moment this command is issued, both a visual (LED) signal and audible signal will be activated on both panels. Both the visual signal and the audio signal switch off on both units once the command is acknowledged in the engine room on panel EET1-Rx. Flashing of LEDs occurs at full intensity regardless of the position of the dimmer switch. An incorrect response to the command is immediately by a warning in the form of a light and sound signal.
When using two receivers (type EET1-Rx), only one can be used for command confirmation. In that case, the other panel serves as the repeater panel. A pushbutton on each receiver panel can be used to select or adjust the status of the receiver/repeater.
