BOSCH LC1 Modular Ceiling Loudspeaker Range

BOSCH LC1 Modular Ceiling Loudspeaker Range, Engineered for indoor public address and voice evacuation applications, the BOSCH LC1 Modular Ceiling Loudspeaker Range provides clear speech reproduction and broad music coverage. The lineup offers five loudspeaker models differentiated by input power (6 W, 12 W, 24 W), driver configuration (4″ and 6.5″ dual-cone, or 6.5″ coaxial two-way), and sound dispersion angles. A modular design allows all drivers to share a single grille dimension and a universal accessory suite, simplifying specification and installation.

Built to maintain emergency communications, LC1 speakers feature built-in protection mechanisms—including ceramic screw terminals, thermal fuses, and heat-resistant wiring—to ensure circuit integrity in fire conditions. The system is certified to EN 54-24, BS 5839-8, and UL 1480/2043 standards for air-handling plenum spaces when paired with the LC1-MFD fire dome. Additional features include integrated light conductors for optional pilot-tone status monitoring (LC1-PIB) and selectable $70\text{ V} / 100\text{ V}$ power tappings.
