The MRC MARINCOM LC-814G1 Sound Power Telephone is a wall-mounted marine communication device engineered for reliable voice communication in demanding shipboard environments. Operating on a 24V DC power supply with an ultra-low power consumption of approximately 0.2W, this sound-powered telephone system enables critical communication between the wheelhouse, engine control room, and steering gear room — especially during emergency situations when the vessel's main power supply has failed. Manufactured from durable ABS material with an IP44 waterproof and dustproof rating, the LC-814G1 is specifically designed for installation in machinery spaces and other harsh marine areas. The system has been tested to IEC60945 standards and holds CE certification, as well as type approval from CCS and DNV classification societies. The unit features a coiled handset cord, stainless steel mounting bracket, and can be interfaced with horn, bell, flashing light, and foot switch accessories.
