Building a Risk-Resilient Plant in a World of Increasing Digital Complexity

 In industrial environments, alarms are the first warning that a process has deviated from the norm and needs intervention. Operators depend on alarms to maintain the stability and safety of critical systems. But in many plants, the alarm lifecycle is riddled with delays, inefficiencies, and gaps in visibility. The result is predictable: higher downtime, quality issues, unnecessary labor costs, and ultimately, increased risk.

By examining every stage of the alarm lifecycle—acknowledgement, diagnosis, response, and prevention—teams can grow beyond basic alerting to a smarter, more proactive approach that reduces operational risks and increases productivity.

This article is not presented as an exhaustive blueprint for removing all operational risks across all plants and industries. It is intended as a general framework that facilities at any scale can use to enhance performance and reliability.

Understanding the Industrial Alarm Lifecycle

To appreciate the value of optimizing alarm processes, it helps to understand how alarms move through their lifecycle. According to the ISA-18.2 standard, an alarm progresses through four distinct states:

• Active/Unacknowledged: A new abnormal condition is detected but no one has responded.
• Active/Acknowledged: Someone has acknowledged the alarm, but the condition is still abnormal.
• Inactive/Unacknowledged: The condition is resolved before anyone responds.
• Inactive/Acknowledged: The alarm is acknowledged and resolved, and the lifecycle is complete.

Any delays in this progression, especially between Active/Unacknowledged and Active/Acknowledged, can impact uptime, safety, and workload. In many plants, these delays are systemic, not individual. Operators may not be on-site; alerts may not reach the right person; critical context may be buried in SCADA screens or process data logs. These issues accumulate over thousands of alarms, often without anyone recognizing the true operational cost of the cumulative impact.

Why Optimizing the Alarm Lifecycle Matters

Accelerating alarm response and reducing active alarm time leads to measurable gains. Improved attentiveness means less time chasing nuisance alarms or hunting through data. Reduced downtime driven by faster reactions means smaller disruptions to production. Higher process efficiency and safety are achieved when operators catch issues before they escalate. Finally, in some industries, like water and wastewater, the implementation of remote alarm systems can reduce labor costs by eliminating staffed overnight shifts.

Most importantly, better alarm management enables teams to shift from reactive firefighting to proactive problem-solving.

Reducing Acknowledgement Time: Getting the Right Eyes on the Right Problem

One of the most impactful ways to improve alarm system performance is by reducing the time between when an alarm occurs and when someone responds. An effective solution ensures alarms immediately reach the right people in the right way.

Consider this scenario: a team of operators at a water plant takes turns being “on-call” during overnight hours. To effectively manage this, their alarm system is integrated with their work schedules, so the alarm system alerts only the active on-call operator at any point in time. If an alarm isn’t acknowledged within a set time window, it is escalated to another operator, and if that fails, escalates up to the plant manager. At each escalation level, alerts begin as push notifications from a mobile app; if they go unanswered, the solution automatically escalates to phone calls, which are far more effective at waking plant personnel in the middle of the night.

The system also supports branching logic, such as notifying the entire team immediately for high-severity alarms at night while routing minor daytime alarms to operators only. And when someone remotely acknowledges an alarm, that acknowledgement syncs back to the plant’s control system and HMI, keeping a single source of truth across systems. Together, these capabilities dramatically shorten acknowledgement time while ensuring alarms are seen, acted on, and recorded reliably.

Diagnosing and Resolving the Problem: Enriching the Activation Phase

In terms of the alarm lifecycle, reducing acknowledgement time is only half the battle. The other half is shortening activation time, the overall time that an abnormal condition is active. In this phase, an effective solution must help operators resolve alarms faster by giving them clearer context and better collaboration tools.

Consider a mobile alarm management app focused on enabling collaboration between team members and the ability to access diagnostic machine data. In this app, each alarm condition includes its own persistent group chat, allowing operators and engineers to share observations, attach photos, and document their steps in a single place. At the same time, the solution provides real-time and historical SCADA diagnostic information so operators can review trends before, during, and after the alarm, browse tags, analyze event logs, and generate detailed reports with trends, tables, and/or deltas. This immediate access to information helps the team understand what has changed and why.

Over time, the responses documented via the app build up valuable institutional knowledge, allowing teams to resolve similar issues more quickly and consistently going forward.

From Resolution to Prevention: The Long-Term Value of Smart Alarm Management

Even well-designed alarm systems can generate thousands of events per day, but with the right tools, plants can significantly reduce that volume and boost performance through structured rationalization and continuous improvement. An effective solution supports this by helping teams follow a standardized, ISA-based approach to defining alarm conditions, eliminating nuisance events, and aligning alarm behavior with best practices. This process not only improves efficiency and operator workload but also strengthens compliance for audits and regulatory requirements. Beyond rationalization, effective alarm management surfaces the insights needed for ongoing monitoring: highlighting bad actors, operator response patterns, alarm frequency by shift or role, acknowledgement performance, and broader enterprise trends. These metrics can be pushed directly into BI or ERP systems, giving organizations clear visibility into system health and long-term opportunities for improvement across multiple plants.

Conclusion: A Smarter Approach to Alarms Reduces Operational Risks

Alarm systems are essential, but they’re only as effective as the processes and tools that support them. SmartSights transforms alarms from simple notifications into actionable, data-rich insights that drive faster response, clearer collaboration, and long-term operational improvement.

By optimizing the full alarm lifecycle—from acknowledgement to prevention—plants can boost uptime, streamline labor, reduce risk, and ensure teams respond not just faster, but smarter.

If your organization is ready to improve alarm performance and build a more reliable, knowledge-driven operations culture, SmartSights offers a direct, practical path to get there.
