FR105 is a 350 W high-power wall mounted fire emergency voice control panel for medium and large building projects. It offers emergency voice broadcasting, MIC paging, USB / MP3 and AUX audio input with 120 V constant-voltage speaker output, programmable air-cooled design and comprehensive fault monitoring, ideal for large-area fire emergency broadcasting and voice evacuation systems.
FR105 fire emergency broadcasting panel integrates an area control panel, audio source module and 350 W high-power broadcasting amplifier in a wall-mounted enclosure. Connected to a fire alarm linkage controller, output modules and constant-voltage speakers, it forms a powerful voice evacuation system for large public or industrial buildings.
When an alarm signal is received from the fire linkage controller, FR105 switches automatically to emergency broadcasting and plays pre-recorded fire messages or live MIC paging to all connected loudspeakers. With higher output power and an air-cooled design, FR105 is suitable for malls, large office buildings, exhibition halls, factories, warehouses, schools, hospitals, airports and other medium- to large-scale projects.
