The project concerns the replacement of the existing Center for Light Signaling with a new Center for Light Signaling and Observation of Damage (K.F.S.K.E.A.B.). The new (K.F.S.K.A.B.) can be connected to existing regulators and it will be possible to connect it to new regulators. There will also be replacement of illuminating signals for incandescent technology with LED-type signals. Finally, the supply and installation of countdown units as well as blank audio devices with call buttons and wireless transceivers will be provided.
