6 W ceiling loudspeaker, suitable for 100 V connection with power tapping of: 6, 3, 1.5 and 0.75 Watt.

The optional back‑box LC3‑CBB fully protects the loudspeaker from dust and dripping water from above, according IP21C.

The loudspeaker frame, grill and back‑box are manufactured from self‑extinguishing ABS according to

UL 94V0.

Certifications and approvals

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.

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 a ceramic screw‑terminal connection block, thermal fuse and heat‑resistant high temperature wiring.

Four primary taps for 100 V are provided on the matching transformer to allow selection of nominal full‑power, half‑power, quarter‑power and one‑eight‑power.

The optional back‑box (LC3‑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 two grommets (11 mm) and for two cable glands (20.5 mm).
