The 64W white LC2-PC60G6-12 Premium-Sound Ceiling Loudspeaker from Bosch provides wide dispersion, high efficiency, high maximum output, ease-of-installation, and wide-range reproduction of music and voice. It is intended for high ceiling applications.
This 12” coax two-way loudspeaker consists of a baffle assembly, grille, back-can enclosure, and internal output-power matching transformer. The rear enclosure provides an optimum internal volume for extended low-frequency performance. The loudspeaker utilizes a comprehensive protection circuit to protect the network, woofer, and tweeter drivers from excessive power levels.
Voice Alarm Loudspeaker
This voice alarm loudspeaker is specifically designed for use in buildings where performance of systems for verbal evacuation announcements is governed by regulations. It is designed for use in voice alarm systems and is compliant with British Standard BS 5839-8 and EN 60849.
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 that the loudspeakers in other areas can still be used to inform people of the situation. It is fitted with a back-can enclosure to increase protection of the cable termination. This loudspeaker has an emergency compliant ceramic screw-terminal block and thermal fuse.
The loudspeaker is secured in ceilings using 4 integral toggle anchors, and has been designed to work together in a wide range of different ceiling constructions. A tile bridge / C-ring is included for safe suspension in a drop ceiling that uses mineral wool, or other fiber-based ceiling tiles from 0.16 to 1.0" (4.0 to 25.0mm) thick.
It can be suspended in open ceiling installations by an integrated 0.37" (9.39mm) rigging point for use with threaded rod, or it can be mounted using the 3 pendant mount tabs on the rear enclosure. A circular template for marking a 15.20" (386.00mm) diameter hole is included with the loudspeaker.
The unit has a 3-way emergency-compliant ceramic terminal block with screw connections (including earth) suitable for loop-through wiring. The four 100 V and five 70 V primary taps are provided on the matching transformer to allow selection of nominal full-power, half-power, quarter-power, eighth-power radiation (in 3 dB steps), and 8Ω. The selection is done via a convenient switch on the front baffle.
Certifications and Approvals
It is designed to withstand operating at the rated power for 100 hours in accordance with IEC 268-5 PHC (Power Handling Capacity) standards. Bosch has also developed the SAFE (Simulated Acoustical Feedback Exposure) 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 great customer satisfaction, long operating life, and less chance of failure or performance deterioration.
