Bosch LS1-UC20E-1 overview

  • 1Description

The LS1UC20E1 Pendant Sphere Loudspeaker from Bosch is a powerful 20W pendant sound projectors designed to be suspended from the ceiling by their connecting cables. It's intended for high quality speech and music reproduction, with excellent sound spread makes them ideal for use in buildings with high ceilings, such as large superstores. It's also suitable for use in voice evacuation systems. This sound projector has a 20W (30W peak) power rating for powerful performance. 

A 16.4' (5 m) color-coded, five‑core connecting cable with each color connected to a different primary tap on the 100 V matching transformer is provided. This allows nominal full‑power, half‑power, quarter‑power or eighth‑power radiation to be selected (in 3 dB steps). The projector meets IP 65 water and dust protection standards, making it ideal for indoor or outdoor use.

Voice alarm loudspeakers are specifically designed for use in buildings where performance of systems for verbal communication announcements is governed by regulations. The LS1‑UC20E‑1 is designed for use in voice alarm systems and is compliant with British Standard BS 5839‑8 and EN 60849.
The loudspeaker is suspended from the ceiling via its five meter, five‑core connecting cable, which is easy to shorten for the desired height. For optional safety, a steel safety cord can be attached.
The loudspeaker has built‑in protection to ensure that, in the event of a fire, damage to the loudspeaker does not result in failure of the circuit to which it is connected. In this way, system integrity is maintained; ensuring loudspeakers in other areas can still be used to inform people of the situation. The loudspeaker is supplied with a ceramic terminal block and thermal fuse.
The use of a high‑quality driver in combination with advanced filtering, have resulted in a very natural sound reproduction with excellent bass response.
All Bosch loudspeakers are designed to withstand operating at their rated power for 100 continuous hours in accordance with IEC 268‑5 Power Handling Capacity (PHC) standards. Bosch has also developed the Simulated Acoustical Feedback Exposure (SAFE) test to demonstrate that they can withstand two times their rated power for short durations. This ensures improved reliability under extreme conditions, leading to higher customer satisfaction, longer operating life, and lessons the chance of failure or performance deterioration.
All ABS parts are self-extinguishing (according to UL 94 V 0). This sound projector complies with the relevant safety and installation regulations of EN 60065.
