Strong interference signals from third-party devices
can impair or completely prevent the function. Do
not place potentially interfering devices such as
screens and mobile phones closer than 30 cm to Li-
sa-Signolux devices and, if necessary, their cabling,
as important event messages such as fire warnings
may be prevented.
Environmental conditions
Units of the Lisa-Signolux system should only
be operated in a dry environment within the
guideline values for temperature and humidity
specified in these operating instructions. Humi-
dity and moisture can lead to failure of the units.
Maintenance and cleaning
The unit is maintenance-free. If it becomes dir-
ty, it can be cleaned with a soft, damp cloth. If
necessary, use only commercially available al-
cohol-based disinfectants. Never use cleaning
agents or disinfectants that contain acetone or
hydrogen peroxide or that are bleaching, cor-
rosive or abrasive. No liquid or moisture may
penetrate the openings of the unit.
