报警防区说明书
本系统首要用于住宅小区，传送住户室内各种安防报警信号到管理核心。系统电路设计上是一个独立的系统。梯口内布线结构为三总线，数据传输选用低速率单线串行编码，通过梯口信号转换器与小区内485总线连接，因而用户防区终端接口板电路简单、成本低，可靠性好。(This system is mainly used in residential quarters to transmit various security alarm signals in the household to the management core. The system circuit design is an independent system. The wiring structure in the elevator entrance is a three-bus, and the data transmission adopts low-speed single-line serial coding, which is connected to the 485 bus in the community through the elevator entrance signal converter, so the user defense zone terminal interface board has a simple circuit, low cost and good reliability.)
