ITC VA-2240WM 2 Zones Voice Evacuation Controller

المواصفات

* Built-in 240W high-efficiency digital power amplifier, integrated 2 power A + B independent dual-speaker loop zone output, each zone has independent LED indicator, independent output control buttons and volume adjustment.

* 4 audio balanced input interfaces for playing any audio source in the zones

* Local emergency PTT microphone input and emergency voice can be configured by PC software to be played in specific zone.

* Automatically detect the working status of each zone loop (fault, normal)

* The 4-channel trigger input/output port can trigger the emergency voice preset by the PC software to the specified zone or the corresponding external power source to the corresponding event warning.

* Support third-party emergency audio input (user-defined emergency audio source)

* Integrated independent EVAC/ALERT voice information player.

* There are online interface for the remote paging microphone and fireman microphone. The connection between each paging station uses standard RJ-45 network port and standard CAT-5 network cable. The voice transmission uses balanced transmission mode for long-distance transmission.
