Best Practices
Alarm Display Design
Prioritize Critical Alarms:
- Use color coding (red for critical, yellow for warnings)
- Sort by level and trigger time
- Highlight unacknowledged alarms
Clear Information:
- Show alarm message, not just alarm name
- Display trigger time and duration
- Include equipment/location context
Actionable Interface:
- Provide acknowledge buttons
- Link to equipment views for investigation
- Show recommended actions or SOPs
Alarm Analysis
Regular Reviews:
- Weekly: Review alarm frequency and standing alarms
- Monthly: Analyze alarm trends and adjust thresholds
- Quarterly: Conduct alarm rationalization sessions
Key Questions:
- Which alarms occur most frequently?
- Which alarms are never acknowledged?
- Which alarms have the longest duration?
- Are there alarm patterns that indicate systemic issues?
