LC3 ￣ uc06 is an economical universal 6 W Ceiling Speaker

 suitable for 100 V connections with 6, 3 and 1.5 Watt power taps. Lc3-uc06-lz is a low impedance (4 Ohm) Ceiling Speaker that can be directly connected to the low impedance amplifier output. The optional bottom box LC3 ￣ CBB can fully protect the speaker from dust and falling objects, and prevent the sound from spreading to the adjacent area through the ceiling pores. The speaker frame, mask and bottom box are made of flame retardant ABS material and meet UL 94v0 standard. Certificate and accreditation all Bosch loudspeakers meet IEC 268-5 power amplifier capability (PHC) standard and can operate continuously for 100 hours at rated power. In addition, Bosch has conducted simulated acoustic feedback exposure (SAFE) tests to ensure that they can withstand twice the rated power in a short period of time. This ensures higher reliability of loudspeakers in extreme conditions, improves customer satisfaction, extends service life, and significantly reduces the probability of failure or performance degradation. CE compliance statement safety compliance with en 60065 regional certification European CE installation / configuration ceiling loudspeakers with built-in spring arms can firmly fix the speakers in the ceiling openings. The thickness of the ceiling can be between 5 and 25 mm. In addition, templates for accurate openings in the ceiling are provided. The electrical connection is made by flexible wires, each color of flexible wire is connected to different connectors of matching transformer. Three connectors for 100 V electrical connections are provided on the matching transformer, allowing the user to select rated full power, half power and quarter power. The optional bottom box (LC3 ￣ CBB) can protect the back of the speaker from dust and falling objects, protect the speaker from insects, and prevent sound from spreading through the ceiling pores to the adjacent area. The bottom box is assembled with the loudspeaker through an embedded structure and has two openings for mounting washers (11mm) and two cable sealing plugs (20.5mm).
