Description

Bosch LS1-UC20E-1-US 20 Watt Pendant Sphere Loudspeaker

Overview

The Bosch LS1-UC20E-1-US is a 20-watt pendant sphere loudspeaker designed for public address and voice alarm applications. Its spherical design provides 360-degree sound dispersion, making it ideal for open-plan areas like shopping malls, airports, and convention centers where even coverage is critical. This unit is EN 54-24 certified for voice alarm systems, ensuring compliance with critical safety regulations for emergency evacuation announcements.

Compatibility

This loudspeaker is designed for use with standard 100V or 70V public address and voice alarm systems. It is compatible with amplifiers and systems that support 20W, 10W, or 5W power taps. The 100V line operation minimizes signal loss over long cable runs, making it suitable for large installations.

Installation Notes

The LS1-UC20E-1-US features a suspension cable and a separate mounting bracket for secure pendant installation. Wiring is accomplished via a screw terminal block, allowing for easy connection to the amplifier's output. The unit is rated for indoor use in environments with ambient temperatures ranging from -25°C to 55°C (-13°F to 131°F).
