The more people that can receive the call, the bigger the chance it will actually get through. Adésys' experience shows that a minimum of 4 recipients in a call list gives enough certainty that an alarm will get through. Make sure you include enough persons in a call list.
We advise you NOT to switch on voicemail for telephone numbers in the call list.
With the Octalarm-Touch and the Octalarm-Touch Pro we also recommend installing the free app Adésys Alarm on your smartphone. In addition to easily accepting an alarm with, for example, your fingerprint, your iris scan or your smartphone unlock code (depending on the capabilities of your smartphone), you also have direct insight into the status of your (connected) diallers and you can set and manage your (connected) devices remotely, anytime and anywhere.
In addition, the dialler allows you to select an alarm as 'critical'. With a critical alarm, the dialler sends a notification via the app even when your phone is on night or flight mode, so you know for sure that a critical alarm will reach you (push-alert).
