Alarm floods are not operator discipline problems alone—they are design debt. TECHNLOGIX PTY LTD rationalises alarms during migrations and hypercare with maintenance in the room.
Principles we apply
- Every standing alarm needs cause, effect, and operator action text.
- Chattering instruments get debounce or maintenance tickets—not louder annunciators.
- Safety alarms stay visible; informational events move to event logs.
- Colours and priorities follow a site standard, not integrator habit.
Measurement
Count alarms per hour per operator station before and after changes. Track acknowledge-without-action rate if your HMI supports it. Improvement should be measurable within weeks.
Politics
Production managers sometimes want alarms for everything “just in case.” We push back with fatigue data—hidden faults are worse than fewer, meaningful alarms.
