Dimming to basis brightness
Options:
This parameter defines the brightness value after the staircase lighting time has timed out. It is the bright-
ness value set after the dimming down time (pre-warning phase). The basis brightness hold time as well
as the time for dimming down after light on (Warning before light turned off) is programmable in the
Parameter window - Gx Staircase lighting
Example
A typical application for a basis brightness is for example, in nursing homes or residential care homes in
hallways, where the lighting is never fully switched off. A basis brightness of approx. 20 % should
always exist. If a patient enters the area, it should be illuminated for a certain time (staircase lighting
time) with maximum brightness (100 %).
