Product Description

Bosch LC4-UC06E overview

The 6W white LC4-UC06E Ceiling Loudspeaker from Bosch can be used for a wide variety of ceiling environments. They provide speech and music in indoor public address applications. The CosCone driver technology, used in this range, stands for delivering outstanding sound quality from a small sized unit. It ensures a wide and equal spread of all octave frequencies and eliminates high-frequency beaming.

Fewer loudspeakers are needed to cover a given area, and the noticeable fading that can occur as a listener walks from one loudspeaker to another area is eliminated. It is a light and compact unit with an unobtrusive, neutral designed front grille.

The 6W range comes with the same wide opening angle, ensuring a wide and equal spread of the important frequency octaves for speech intelligibility and music clarity. The LC4 range also includes a back-box and metal fire-dome. The LC4 range is installation friendly. A cutting template is supplied with each unit, and the loudspeaker is secured in ceilings up to 2″ (50mm) thick using 2 integral screw driven clamps.

Power tapping on both 70V and 100V allows selection of full-power, half-power, quarter-power, eight-power radiation, and 8 Ω. A selector at the front of the frame simplifies the required selection of the power setting. The loudspeaker grille, standard supplied, can be secured to the loudspeaker unit with a quick bayonet fitting after installation of the loudspeaker into the ceiling.

The included back-box (LC4-CBB) protects the rear of the loudspeaker from dust, falling objects, makes the unit vermin proof, and prevents sound traveling via the ceiling cavity to adjacent areas. The back-box is assembled with the loudspeaker by means of a snap-in construction and has knock-out holes for 2 grommets 0.4″ (11.5mm) and for 2 cable glands 0.8″ (20.5 mm) aside and on the top.

You can easily install individual loudspeakers and loudspeakers / fire-dome combinations. The metal fire-dome (LC4-MFD) is flame red in color. Its mounting is fixed in the ceiling prior to the ceiling speaker mounting. The fire-dome is provided with a safety cord allowing the installer to temporarily hang the loudspeaker in the fire-dome, while connecting.

Both the loudspeaker and back-box have provision for mounting the line/supervision board (sold separately). The loudspeaker has a provision also for adding a capacitor in case the loudspeaker is used in systems with DC supervision.

Certifications and Approvals

It is designed to withstand operating at their rated power for 100 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 the speakers can withstand 2 times their rated power for short durations.

This ensures extra reliability under extreme conditions, leading to greater customer satisfaction, longer operating life, and much less chance of failure or performance deterioration.
