Illuminated buttons
If too many illuminated buttons are connected, the lighting may switch on spontaneously or switch on permanently.

Maximum load current
The contact current given in the technical data is the maximum value and may be subject to restrictions – more information. If the information provided indicates that the relay in the device is insufficient, it is recommended to use an external switching element (e.g. contactor) adapted to switch large surge currents.

LED light sources
When using LED light sources and illuminated buttons, the phenomenon of incomplete switching off may occur (e.g. glowing, flashing).

Anti-blocking function
The anti-blocking function does not allow the lighting to be on continuously after the staircase switch is blocked, i.e. after blocking the switch (e.g. with a match), the automatic device will measure the set time and turn off the lighting.
