FR104 fire emergency broadcasting panel is composed of an area control panel, audio source module and 150 W broadcasting power amplifier. It works together with fire alarm controllers, output modules and loudspeakers to form a complete fire emergency broadcasting and voice evacuation system.
When the fire linkage controller outputs a start signal, the panel automatically switches to emergency broadcast mode and sends pre-recorded fire emergency messages or live MIC paging to the connected speakers. FR104 is suitable for shopping malls, office buildings, factories, schools, hospitals and other projects that require reliable voice evacuation.
