Digital Call System: Shorten Downtime with Rule-Based Escalation

A digital call system automatically alerts the responsible team when a fault occurs – triggered at the push of a button, from a dashboard or by a sensor value. The search for the right contact ends: the call reaches maintenance, logistics or shift management within seconds, and the response is documented and traceable.

From shouting to rule-based escalation

In many plants, alerting still runs via shouting, the phone or searching for a person. That costs minutes which feed straight into downtime. A digital call system replaces this chance with clear rules: who is notified for which fault, and what happens if no one responds? This escalation logic ensures no call is left unanswered.

Andon button, dashboard or sensor as the trigger

The trigger is flexible: a physical Andon button on the line, a control on the touch dashboard, or an automatic threshold from the machine data. The digital call system is thus the active counterpart to the Andon board, which makes the state visible – the call system ensures that state is acted upon. The concept goes back to the Andon principle from lean management.

Effect on response time and downtime

Because the right team is reached immediately and automatically, a digital call system shortens the response time and therefore the mean time to recovery after a fault. As every call is logged with a time stamp, clusters can be identified and tackled specifically – pure alerting becomes a data basis for process improvement.

Integration without a new system

Peakboard sends alerts from existing shop floor dashboards straight to Microsoft Teams, email or a signal light, using the machine and ERP data that is already connected. The call system is a building block of digital shop floor management and can start on one line and roll out step by step.
