Rethinking Industrial Alarms for a Safer, Smarter Plant
As plants become more complex and digitized, alarms must evolve beyond simply signaling problems; they need to enable action. This article looks at how alarms are transforming into intelligent safeguards that strengthen safety, reliability, and efficiency. It highlights their role within Safety Instrumented Systems (SIS), integration with digital platforms, and the use of strategies like alarm rationalization to reduce flooding. With smart design and proper lifecycle management, alarms can help plants reduce risk and move toward safer, smarter operations.
In a metals refinery, managing acid concentration is critical for safety, productivity, and equipment protection. This application note shows how the SLA Safety Logic Solver and Alarm is used as part of a SIL 2 Safety Instrumented Function to monitor redundant transmitters, pump status, and shutoff valves. With 16 configurable alarms, built-in logic equations, and simple 1oo2 voting strategies, the SLA delivers advanced alarming and shutdown control to help prevent dangerous out-of-spec conditions.
Understanding Alarm Trips Part 4: Alarm Trip Relay Responses
Part 4 of "Understanding Alarm Trips" dives into how alarms take action. Learn the basics of alarm relay responses, including the difference between Normally Open (NO) and Normally Closed (NC) contacts, as well as common relay types: SPST, SPDT, and DPDT. See how each setup works, when to use them, and how they help trigger everything from indicator lights to full safety shutdowns. This video helps enable you to match your alarm trip's response to your process needs for reliable performance when it matters most.
Safeguarding Power, Ensuring Safety: Hydrogen Purity Alarming with the SPA2
Hydrogen cooling is vital for keeping large power generators efficient and safe, but even small drops in purity can cause major losses or explosive hazards. This case study shows how the SPA2 Programmable Limit Alarm Trip delivers fast, reliable trip action to guard against contamination risks. Learn how the SPA2 can protect personnel, prevent costly downtime, and keep generators running at peak performance.
