The retractable combined Perimeter / Deck Edge Light is designed to mark the deck´s outer limits (perimeter circle) in a way which does not dazzle pilots vision. It is fully retracted to provide an absolutely even deck surface and therefore provides an obstacle free deck, enabling ball sports etc. It will pop up pneumatically when used for helideck operation. The housing is made of massive seawater resistant aluminum for performance in extreme marine environments. The visible surface around the top-light can be adapted to the surface of the surrounding deck, e.g. teak, resin compound or alike.
System integrity and operational reliability is controlled by Optonaval´s internal electronics combining multiple sensors measuring temperature, humidity and electric current, providing 24/7 monitoring of the CFD/EL´s status. In that respect, the CFD/EL will show an upcoming malfunction before it actually fails. Easily exchangeable standard dry agent cartridges provide effective absorption of residual humidity. Nitrogen filling -as alternative mode of humidity control- is available as optional feature.
