The LC2-PC30G6-4 is a 4-inch two-way Premium-sound Ceiling Loudspeaker which provides; wide dispersion, high efficiency, high maximum output, ease-of-installation, and wide-range reproduction of music and voice. It consists of a baffle assembly, grille, back-can enclosure, 4-inch coax two-way loudspeaker and internal output-power matching transformer. The loudspeaker features a waveguide coupled titanium coated dome tweeter. The rear enclosure provides an optimum internal volume for extended low frequency performance. The loudspeaker utilizes a second order crossover network at 3.3 kHz, with a comprehensive protection circuit to protect the network, woofer, and tweeter drivers from excessive power levels. The loudspeaker can be installed optionally with the LC2-PC60G6-10 ceiling subwoofer to enhance the low frequency reproduction down to 45 Hz


Functions:

Voice alarm loudspeaker Voice alarm loudspeakers are specifically designed for use in buildings where performance of systems for verbal evacuation announcements is governed by regulations. The LC2-PC30G6-4 is designed for use in voice alarm systems and is compliant with British Standard BS 5839-8 and EN 60849.

Protection:

 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.
