In Part 6 of “Understanding Alarm Trips,” we explore how alarm trips can be applied in hazardous locations where Intrinsic Safety (IS) is the method of protection. This video introduces the SPA2IS Intrinsically Safe Alarm Trip from Moore Industries, showing how it can simplify IS installations by acting as an associated apparatus. You’ll learn how traditional IS systems use separate Zener Diode barriers or Isolated barriers to limit energy and prevent ignition, and why those solutions often add cost, complexity, and grounding challenges. We’ll explain how the SPA2IS integrates the barrier directly into the alarm trip, reducing wiring, cabinet space, grounding needs, and installation costs, all while maintaining safety compliance. By understanding how associated apparatuses work, you’ll see how the SPA2IS can streamline your hazardous area alarming and lower the total cost of ownership without compromising safety.
