The RM-300X Remote Microphone is an essential component within the Integrated Voice Evacuation System, designed to provide precise, zone-specific communication during emergency and routine announcements. The RM-300X is engineered to allow authorised personnel to initiate live voice broadcasts and control multiple zones individually or in groups, ensuring accurate message delivery across designated areas. It features 13 function switches, each accompanied by an indicator light for real-time status visibility, and includes a protective cover to prevent unintended activation. This level of control is particularly important in large-scale facilities such as commercial complexes, transportation hubs, and institutional buildings, where clear communication and rapid response are critical to occupant safety. When additional zone management is required, the system can be easily expanded through the RM-210F Remote Microphone Extension, which adds functionality in 10-switch increments. The RM-300X Remote Microphone supports a structured and scalable approach to emergency voice communication, reinforcing operational reliability in complex building infrastructures. With its robust configuration capabilities and integration compatibility, the RM-300X plays a pivotal role in meeting the demands of modern voice evacuation systems.
