Alarm Design and Management

Stay Informed, Not Overwhelmed

Make It Easy to Do the Right Thing and Hard to Do the Wrong Thing

Poorly designed and maintained alarm systems can confuse operators with alarm floods during abnormal system states, precisely when clarity and corrective action is needed most. NovaTech partners with industry thought leader PAS to implement their proven seven-step process for ensuring that alarms are clear, prioritized, and actionable in every system state.


Develop an Alarm Philosophy customized to each plant that defines best practices for alarm design, implementation, and maintenance.


Data Collection and Benchmarking incorporates PAS and EEMUA best practices, provides a base line for continuous improvement, and identifies “Bad Actor” alarms.


“Bad Actor” Alarm Resolution reconfigures the most frequent, irrelevant, and chattering alarms to reduce alarm load by approximately 60%. This gains support among operators for subsequent maintenance and improvements.

Detailed Design

Alarm Documentation and Rationalization brings all plant stakeholders – board operators, process and control engineers, health and safety representatives, environmental compliance personnel, production and maintenance engineers – together to assess the validity, priority, causes and consequences of alarms.


Alarm System Audit and Enforcement starts when the rationalization process concludes, and requires ongoing Audit and Enforcement to avoid “alarm creep” and protect efficiency gains.


Real-Time Alarm Management allows for dynamic adjustment to different stages of plant operation such as startup and shutdown, feed and product changes, and equipment maintenance. Techniques include state-based alarms, alarm flood suppression, and alarm shelving.


Control and Maintain Performance with established metrics and infrastructure for optimal alarming. Plant managers can maintain performance goals at the console, unit, site and enterprise levels.

  • Introducing FlexBatch 5.0

    FlexBatch integrates recipe management and the automation layer so operators can quickly and easily develop, scale up, modify and schedule batch manufacturing recipes for products ranging from beer to chocolate to specialty chemicals and more. FlexBatch delivers shorter time to first batch, reduced changeover times, increased throughput and production yield. New and existing products are brought to market faster and at lower cost, providing a strategic and financial advantage. Production staff can execute library procedures to overcome process upsets. All of which means a more nimble, responsive, and profitable process.

  • Introduction to ISA 18.2 Alarm Management 6-part Webinar Series

    In June of 2009, the ISA released standard ISA 18.2, Management of Alarm Systems for the Process Industry. This landmark document is the first true standard on how companies are expected to design, implement and maintain alarms generated by process control systems. In this webinar we shall provide an overview of the ISA 18.2 standard, the regulatory impact of this standard, and what you can do to ensure your facility is compliant with these requirements.
