The activation-detecting device is the ideal complement for an Obermatic door operator. Thanks to this device, we have not to activate any keys or produce a credential – it simply opens every time it detects somebody approaching, thanks to the proximity radar that sends a signal to the OBERMATIC in order to start an opening cycle. Also, with the purpose of preventing it from opening every time something moves near the radar, it allows the user to configure the operational range and the response to detected motion.
