By making your dialler redundant, you increase the chance that alarm notifications will actually come through.
A dialler is redundant when it can send alerts via multiple, independent connections, for example via GSM and PSTN (simulated analogue line). The way in which systems are made redundant varies per solution and has a major impact on the ultimate reliability.

For Octalarm alarm diallers, we also recommend installing the free Adésys Alarm App on your smartphone. You can mark an alarm as “critical” in the dialler. In the event of a critical alarm, the dialler sends a push notification via the app, even when your phone is in silent mode. This ensures that critical alarms are not missed.
