There are alarm dialers and modems for analogue telephone lines (PSTN), ISDN lines and there are GSM/GPRS models for situations where you don't have a telephone line. If you connect the dialer to a VoIP (Voice over IP) connection or other form of internet telephony, Adesys also recommends a number of additional measures such as an emergency power supply for the internet modem or an ADSL splitter with built-in overvoltage protection. You can contact Adesys' sales department on +31 (0)174 794022 or via firstname.lastname@example.org. for advice and help with product choice.
