Deck/Nautical Equipment/372188-372197 TELEPHONE BATTERYLES SELECTIVE

These telephones do not require a source of electric power for calling and communication.   Rotating handle will generate electric power to ring the other station, and accumulated power is used to amplify acoustic sounds to make conversation loud and clear.  They are roughly classified into two systems; Direct Telephone and Selective Telephone.   The latter allows maximum 12/24 telephones to configure (one conversation link).   And they are possible to connect to Intrinsically Safe Types, shown in the layout drawing below.   Each telephone has relay inside terminal so that optional devices such as bells can be equipped. 

这些电话不需要电源就可以通话和通信。旋转手柄会产生电能给对方响铃,累积的电能被用来放大声音,使谈话变得响亮而清晰。它们大致分为两种系统:直拨电话和选择性电话。后者允许最多配置12/24部电话(一个对话链路)。它们还可以连接到本质安全类型,如下面的布局图所示。每部电话在终端内部都有继电器,因此可以配备铃声等可选装置。
