Core functional features of the product
Integrated control: Integrated audio source switching, partition management, fault diagnosis, scheduled broadcasting, AVC environment volume automatic adjustment, network expansion partition, panel physical shortcut keys, supporting one click emergency evacuation mode.
One click emergency broadcast: The red emergency button on the panel triggers the fire broadcast with one click, automatically playing the preset evacuation voice, lighting up the zone alarm indicator lights, and quickly executing the emergency broadcast for the entire area/designated zone.
Audio source and scheduled broadcast: Built in 1GB flash storage for broadcasting audio, supporting simultaneous broadcasting of local audio source, external CD/FM, remote network audio source, and PTT emergency microphone; The software is set to automatically play programs at scheduled times, with a maximum broadcast priority of 255 levels, to achieve complex scheduling logic.
AV automatic volume control: 4-channel environmental noise detection input, equipped with HN-D32N noise probe, automatically adjusts the broadcast volume according to the on-site environmental noise, and can separately set the 24V phantom power supply and input gain for each input.
Full link fault inspection: Real time monitoring of main/backup power, power amplifier, speaker circuit, communication, software and hardware faults, accurate positioning of fault points; Support redundant configuration of primary and backup power amplifiers (one backup one, one backup two, two backup one, and two machines sharing two backups), with automatic switching of backup power supply in case of line short circuit.
Flexible partition expansion: equipped with 4 100Mbps adaptive Ethernet ports, network cable expansion system partition and remote monitoring; Built in monitoring speaker, local and remote network two-level system monitoring.
Fire linkage: 8-way dry contact fire input, connected to the fire alarm host, automatically starts the corresponding zone emergency broadcast upon receiving the fire alarm signal.
