Indicator Mounting
You can choose any of the following three ST status indication options:
1.
Use the backlit pictograms integrated in the lift cabin control panel.
2.
Add optional light guides to the existing ST LEDs to conduct light to two panel
holes.
3.
Connect two optional LEDs to ST with a cable.
Safety
If the LEDs are cable connected, make sure that the electric isolation
between the panel and the loudspeaker is 1,500 V at least.
Make sure that the isolation distance between the panel
and the loudspeaker is 1.5 mm at least.
You are prohibited to use standard metal LED holders
(for an example see the figure to the right).
Note
Make sure that your way of indication complies with the applicable legal
regulations. Indicators, however, are unnecessary for ST operation
(communication).
