Wheelock ST-H30 30W Multi-Tap Horn Speaker

The Wheelock ST-H30 is a high-performance 30-watt horn speaker designed for use in fire alarm systems, public address, and general signaling applications. Manufactured by Wheelock (now part of Eaton), this multi-tap horn features a built-in transformer that allows for flexible power settings at 25V or 70V line voltages, making it versatile for various installation environments such as schools, offices, warehouses, and industrial facilities. Key features include weatherproof construction for indoor/outdoor use, high sound pressure level (SPL) output for clear audibility over long distances or in noisy areas, and adjustable mounting bracket for precise aiming. Advantages over similar products include its rugged die-cast aluminum housing that resists corrosion and vandalism, wide frequency response for intelligible voice reproduction, and compatibility with most voice evacuation systems. Benefits include reliable performance in emergency notifications, reducing the risk of miscommunication during crises. Drawbacks may include its larger size compared to compact speakers and the need for professional installation to optimize sound dispersion. This model excels in applications requiring high-decibel output, such as mass notification systems, offering superior durability and sound quality compared to basic plastic horns.
