The wireless switch-off button is used to cancel active calls. It is installed in the same room as the wireless pull-cord button, so that calls can only be cancelled when an assistant is actually on site.
The wireless switch-off button is battery powered and can therefore be installed without any cabling requirements.
Easy-to-change battery
If the battery power decreases over time, this is indicated by a flashing LED on the device. Only the cover needs to be removed to replace the battery.
Optional power supply via mains adapter
Power can also be supplied via the wireless call module power supply. The battery then serves as a power buffer for power failures.
