Semi-decentralized emergency lighting

The big advantage of semi-decentralized emergency lighting is that the battery set is assembled at the beginning of the light line and that it supplies a maximum of 12 LEDs over a maximum distance of 50 metres. The 12 LEDs can be assembled on the blind covers and can serve as night / passage lighting. The advantage of a central battery is easy maintenance. After all, replacement takes place at a central location and there is no need of scaffolding to access hard-to-get-to places. The battery is equipped with a self-test system.
