Telguard System is a wireless alarm system that serves as a backup to the land line fire system. The Telguard system monitors voltage and current on the incoming phone line to detect when the line is cut or becomes otherwise inoperative. It then automatically switches all system communications to cellular service. The Telguard product communicates with the monitoring center, just like an alarm panel – only it uses the wireless network instead of the compromised land line connection.
