VGSM-120  GSM/GPRS Universal Communicator

VGSM-120 GSM/GPRS Universal Communicator

The VGSM-120 is a GSM interface and a standalone device capable of generating voice dialer messages and SMS event notifications. Its onboard outputs can be triggered remotely via telephone to activate external equipment or indicators. The VGSM-120 simulates the PSTN line
and decodes Contact ID format, so it is virtually “invisible” to the control panel it is connected to.

Simple to install and program (plug and play approach), the VGSM-120 is equipped with a quad band GSM/GPRS radio and remote antenna with magnetic base. Its extremely small size and low current draw allows for installation inside the control panel’s cabinet and does not require an
additional battery.

The VGSM-120 is the best solution for reliable GSM alarm communication back up for the majority of applications, whether new or existing system upgrades.
