Diver Panel

The Diver Signalling System is developed to enable exchange of messages between a submarine and divers. The system consists of one Central Unit placed inside the submarine and one or more Diver Panel Units placed outboards.


In its existing configuration all units have four push buttons and four lamps marked with the figures 1-4. To create a message any combination of lamps is activated by pressing the corresponding push buttons. The same lamps are then lit on all panels in the system. The lamps can be lit in any order and also by operating on any panel in the system.
The lamps are extinguished by a push button in the central unit, but also by pressing any push button on any panel in the system and holding it for 3 seconds.

Except for the push buttons and lamps mentioned above all panels have a lamp for power on indication and a push button for lamp test.

The Diver Panel Unit is machined from a massive piece of POM (plastic material) where the lamps and push buttons have been mounted. The whole unit is then moulded into a solid block to make the unit water and pressure resistant. The push buttons are made with a pressure-balanced technique so that the operating pressure is totally independent of the outside pressure. All parts exposed to water are made of plastic or stainless steel. In the existing design a connector type SubConn IL10M is used for connection but other solutions could be offered.

The Central Unit consist of an aluminium box with a panel similar to the Diver Panel Units. The system is normally powered by 24V DC but other supply voltages could be offered on request. An isolated DC/DC-converter is used to separate the system galvanically from the submarine mains, thereby eliminating the risk for an earth fault in the submarine in case of damaged cables or plugs. The Central Unit is also equipped with means for earth fault indication.
