Open area lighting can be automatically prepared by inserting an emergency lighting scene. In the Property Page for the lighting scheme there is a button to insert “anti panic calculation surfaces” on each piece of floor in the room, even if the floor is tilted or consist of areas in different heights. The geometry is copied from the floor minus 0.5m from the walls. It is also possible to edit the surfaces manually.

The way to insert an open area luminaire arrangement is similar to that in the escape route lighting. A right click on the open area calculation surface opens the Property Page for the luminaire arrangement.

This tool calculates the maximum distance for the selected fittings taking into account the desired minimum illuminance level and uniformity. You can see here the maximum distance lengthwise and crosswise between the luminaires and between luminaires and the border of the open area calculation surface. The arrangement will be placed symmetrically above the open area surface.
To calculate the “open area” which means the unobstructed floor, you have to select in the calculation setting not to take the furniture into account.

Those luminaires, which are in use for emergency lighting, are marked with the expression “emergency luminaire”.
