The GSM back-up, fitted with its dedicated battery, connects easily on all SURTEC security terminals.The GSM back-up is therefore compatible with all INTERVOX alarm systems.
The GSM back-up undertakes the supervision of the presence of the PSTN telephone line.
In case of a line cut, the module takes automatically over, guaranteeing the alarm
transmission via the GSM network. The GSM back-up operates within the 45 seconds following the detection of an absence of telephone line and secures the installation under any circomstances.
The GSM back-up can be used as a GSM transmitter on installations with no
telephone line.
