Voice over GSM

The GSM Converter Module allows the M30 to use a GSM mobile connection to send and receive voice calls; this is in addition to a PSTN connection.

The Module comes with a separate dedicated internal battery backup and is designed as a separate dedicated unit so it can be installed in the best location for a signal, which is often not the best location for installing an M30.

This Module can be used either to provide a dedicated GSM line if there is no PSTN line available or can be used as a backup device. The GSM module can monitor a connected PSTN line; if that line fails for any reason, the GSM module will automatically switch the M30 to the GSM line.

SMS over GSM

This module works in addition to the standard PSTN and GSM voice modules. It allows you when configuring the unit to specify whether an alarm call recipient gets a Voice message or an SMS.

If you specify SMS, the recipient will receive an individual SMS for each active alarm channel.

Each channel has a unique configurable text message, so you are not stuck with standard text e.g. “Fire in hanger 1” instead of “Channel 1 Alarm” etc.
