The GSM LineGuard is an alarm signalling product from Bold Communications which converts PSTN to GSM.  Ideal for locations without a fixed phone line, the LineGuard works with the digicomm output from any standard alarm panel or PSTN telecom device.  Single path PSTN alarm signalling is easily transformed to dual path with Contact ID signalling to the ARC.  There is no restriction as to which GSM Network can be used and the device can also be programmed to transmit SMS for instant alarm reporting to the user’s phone.

Simple to set up and use, the GSM LineGuard is used for a wide range of deployments including temporary site monitoring, lift alarms, mobile applications and high security installations where third line, independent backup signalling is required.
