安装要求  Installing requirements
每节车厢扬声器个数不少于10个，应沿车厢内部横向对称布置，并与车厢内装协调一致，布置应该使车厢广播声音均匀。每节车厢应急对讲装置安装不少于3个，对应急对讲装置安装位置应方便乘客使用，并保证完全处于摄像机的有效监视范围内。
Number of loudspeakers in each car shall be no less than 10, which shall be arranged with transverse symmetry along car interior, and coordinated with the car interior, to let sound of train broadcast even.  Number of emergent intercommunicating devices in each car shall be no less than 3, the installing position of emergent intercommunicating devices shall be convenient for passengers to use, and make sure completely in efficient monitoring range of video camera.

应预留足够的空间安装无线调度通信车载台及接收天线，具体安装位置和方式设计联络时确定。
Sufficient space shall be pre-reserved for installing on-board desk of wireless dispatching communication and receiving antenna, specific installing position and mode will be determined during design liaison.
