VST-1908 Series

The VST-1908 Converter Series is designed to create a bridge between PSTN control panels and IP/cellular networks in a security industry rapidly migrating from traditional landline home phone service to IP/cellular communications.

Compatible with All PSTN Panels Using Contact ID

The VST-1908 Series adapts any PSTN alarm panels using the Contact ID protocol for IP- or cellular-based central stations, converting PSTN CID reports into the SIA protocol and CID over GPRS or into DTMF CID over GSM/3G.

Two-Way Voice

The VST-1908’s virtual voice channel preserves the existing two-way communication between the host PSTN panel and monitoring centers.

Money-Saving Benefits

The VST-1908 Series features quick and easy installation. Its LED indication of GSM/3G registration status enables installers to ascertain whether the GSM/3G registration process is successful.

Easy Programming and Firmware Updates

You can configure the VST-1908 via simple web or SMS programming. The firmware update capability allows the converter to acquire new features and enhance performance.

ARS Software

The VST-1908 Series works with the Alarm Receiving Software (ARS) to deliver readily converted alarm data to the central station.

RMR Protection

The VST-1908 protects RMR (recurring monthly revenue) by bringing IP/cellular technologies to existing PSTN alarms and by supporting services that customers value, such as two-way voice.
