LC5-WC06E4 Ceiling Loudspeaker
www.boschsecurity.com
The LC5 WC06E4 is an extreme compact ceiling loudspeaker, suitable for speech and background music reproduction. The design of the front grille perfectly matches with current available recessed luminaires, integrating light and sound.
The optional back box LC5 CBB fully protects the rear of the loudspeaker from dust and dripping water from above, making the combination IP 44 protected.
The loudspeaker frame, grille and back box are manufactured from self extinguishing ABS according to UL 94 V 0.
This ceiling loudspeaker is suitable for use in low ceiling applications with low noise level. The small driver used in the unit stands for delivering good sound quality from a small sized unit and provides a wide opening angle for the important frequency octaves. Fewer loudspeakers are needed to cover a given area, and the noticeable “fading” that occur as a listener walks from one loudspeaker to another area is eliminated.
The loudspeaker (with assembled back box) is suitable for use in humidity-, chlorineand salty environments.

Quality assurance
All Bosch loudspeakers are 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 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.

Installation/configuration notes
Installation is easy with two integral leaf springs that securely hold the loudspeaker in its cut out. The integral leaf springs can be adjusted in three positions to accommodate ceiling thicknesses from 5 mm to
25 mm. The size of the ceiling cut out opening is standardized on available 3” (76.2 mm) cutting hole saws.
No tool required for fitting the loudspeaker into the ceiling cut out.
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 has ceramic screw terminal connection blocks, thermal fuse and heat-resistant high temperature wiring.
Connections are made using two 2 way screw terminal blocks at the rear of the loudspeaker, where each incoming and outgoing conductor of the same potential can be connected to a separate terminal. Power tapping on both 70 V and 100 V allows selection of full power, half power, quarter power and eight power radiation, and 8 Ohm.
The optional back box (LC5 CBB) protects the rear of the loudspeaker from water and 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 on top two knock out holes for two rubber cable grommets
(11 mm/0.43”), standard supplied.
