原因何在 CERTAS alarm Digital+ automated alarm notification？

With CERTAS alarm Digital+, you can always rest asssured that all necessary measures will be taken in the event of an alarm - at all times and in all circumstances. When an alarm is triggered, our system will automatically call you and play a pre-recorded voice message to inform you about the type of alarm (e.g. robbery or fire alarm) and the affected location.
The voice message will prompt you to acknowledge the message by pressing a button, indicating that you have understood the notification. However, the voice message cannot answer any questions. After successful acknowledgement or if the call is not answered, the process will proceed according to the defined instructions. This process will be repeated up to three times. If the voice message is still not acknowledged after the third attempt, or in
case of system malfunctions, an employee of the alarm monitoring centre will intervene in the process.
