    • A system and a device for surge protection are provided to protect equipment stably even in an unfavorable grounding environment by flowing a surge component to a ground through a pole transformer or a communication terminal. A system(100) for surge protection includes first and second surge input preventing devices(110,120). The first surge input preventing device removes a surge component of voltage inputted through AC power to transmit the voltage without the surge component to an electronic device. The second surge input preventing device removes the surge component of a signal inputted through a communication line to transmit the signal without the surge component to the electronic device. The first and second surge input preventing devices are commonly connected to a common ground.
    • 提供用于浪涌保护的系统和装置,即使在不利的接地环境中,通过极变压器或通信端子将浪涌部件流到地面来保护设备。 用于浪涌保护的系统(100)包括第一和第二浪涌输入防止装置(110,120)。 第一浪涌输入阻止装置去除通过AC电力输入的电压的浪涌分量,以将没有浪涌元件的电压传送到电子设备。 第二浪涌输入防止装置去除通过通信线路输入的信号的浪涌分量,以将没有浪涌元件的信号发送到电子设备。 第一和第二浪涌输入防止装置通常连接到公共地面。

    • PURPOSE: A fire monitoring apparatus is provided to minimize customer service blank by informing disconnection between a current sensor and a fire alarm unit. CONSTITUTION: A current sensor unit(100) senses current signal generated when fire receiver(400) executes an alarm(500), analyzes the current signal level of the sensed current signal, and generates information related to fire occurrence. The current sensor unit generates the response signal corresponding to a disconnection test signal. A fire alarm unit(200) executes fire information processing after receiving information related to the fire occurrence. The fire alarm unit checks disconnection by receiving the response signal from the current sensor unit.
    • 目的:提供消防监控设备,通过告知电流传感器和火灾报警单元之间的断开来最大限度地减少客户服务空白。 构成:电流传感器单元(100)感测当火灾接收器(400)执行警报(500)时产生的电流信号,分析感测到的当前信号的当前信号电平,并产生与火灾发生有关的信息。 电流传感器单元产生对应于断开测试信号的响应信号。 火灾报警单元(200)在接收到与火灾发生有关的信息之后执行火情信息处理。 火灾报警单元通过接收来自当前传感器单元的响应信号来检查断开连接。
