Please note:
This function is not available in the USA and in Canada.
Installation tip:
When the buzzer on the UPS is switched on with the switch, an interrupted beam is indicated with a buzzer signal. This
function is very helpful after installation to check the proper function of the UPS as well as that of the connected light
curtain.
