configured by system software in terms of On/Off, the name of audio, multicast

address and the type of interfaces, etc. During installation, the external audio

source is required physically connection with the inputs and by using X-SMART

software, X-NPMI/EN and X-DCS2000/ EN to select the target zones and audio,

the audio source can be delivered.

X-SMART software, voice alarm zones of each X-DCS2000/EN can be planned in

accordance with fire alarm zones as well as the adjacent zones which required

by international voice alarm standard. When fire alarm triggering the X-NRI/EN,

it automatically communicate with the triggered X-DCS2000/EN and override the
