AtlasIED IED5454AMP GLOBALCOM EN54-16 4-Channel Power Amplifier | 500W

The AtlasIED GLOBALCOM 5400 Series power amplifiers are purpose-built for EN54-16 certified voice alarm and public address systems in commercial, institutional, and life-safety installations. Systems integrators specifying compliant distributed audio infrastructure rely on these amplifiers to pair with the 5404DZM or 5432DZM zone managers, creating a fully verified EN54-16 solution without cobbling together third-party components. The Class D switching topology eliminates the bulky output transformers found in conventional 100V line amplifiers, directly reducing rack weight, cabinet costs, and ongoing energy consumption to roughly one-third that of traditional designs.

Each amplifier ships with comprehensive internal protection covering DC faults, low- and high-frequency anomalies, thermal overload, short circuits, and current limiting — all without operator intervention — making these units well-suited for unattended equipment rooms in airports, transit facilities, healthcare campuses, and large commercial buildings. The 100V floating direct outputs simplify wiring to distributed speaker lines, and front-to-back airflow with temperature-controlled variable-speed fans keeps the 2U chassis cool in densely loaded racks.

Redundant power input is a core life-safety requirement, and the 5400 Series addresses it with an automatic 24VDC battery backup circuit that transfers seamlessly on mains loss with no drop in output power. High-Tech Surface Mount Technology construction and discrete power amplifier modules contribute to the reliability demanded by fire and emergency communication system standards, while the 36-month warranty reinforces long-term confidence for facility owners and system specifiers alike.
