AtlasIED IED5411EOL End-of-Line Speaker Load Module | ≥ 200W

The AtlasIED End-of-Line Speaker Load Module is engineered for life-safety and mass notification installers who need verifiable speaker circuit integrity across 70/100V distributed audio systems. Installed at the terminal point of a loudspeaker daisy-chain, it presents a measurable load at approximately 20 kHz to allow upstream supervision systems to confirm continuity all the way to the last speaker in the run — without adding a return wire or disrupting audible paging and emergency audio performance.

These modules are purpose-built for integration with AtlasIED GLOBALCOM and 5400 Series systems. GLOBALCOM deployments operate in conjunction with DNA Series, T112, and T112C amplifiers, while 5400 Series installations leverage Digital Zone Managers paired with 5400 Series and DNA Series amplifiers to deliver zone-by-zone speaker line supervision across large, multi-zone facilities such as airports, campuses, hospitals, and transit hubs.

Correct installation requires a continuous daisy-chain wiring topology with no branches or parallel taps, and one module placed at the end of each supervised output. This design discipline, combined with AtlasIED's supervision architecture, gives commissioning engineers and facility operators a reliable, standards-aligned method for confirming speaker circuit health in code-compliant emergency communication systems.
