Description
Do you need an intercom to switch on lights or call a lift, but the switched devices are far away and laying cables all the way to the intercom isn't an option? Use an external IP relay, which is controlled using HTTP commands from a 2N IP intercom or access unit. The command is sent to the relay in unsecured form. You can also use the IP relay input. Connect an exit button, for example, to switch the output locally.
