隔离模块

 型号:SIGA-IM

 -内置微处理器CPU和非遗失性存储器

 -软地址,自动编址,生成连线图

 -回路短路监测,故障排除后自动恢复

 -占用一个探测器地址

 -红/绿LED状态指示

  -工作电压:15.2-19.95V

 -工作电流:正常时45uA,激活时45uA

 -按ISO-9001标准设计,制造

 

外形和安装形式同SIGA-CCA.

 隔离模块允许一部分SIGNATURE回路在出现短路的情况下继续工作,这个模块可以设置在CLASS A回路上的任意点,如果回路出现故障,隔离模块将自动切断其后面所有的设备电源.动作之后,隔离模块将不间断地检查回路故障端以解决短路现象是否依然存在,当故障排除后,隔离模块自动将整个回路恢复正常.

 

Description
The SIGA-IM Isolator Module is an addressable device that
protects a signaling line circuit (SLC)from a to wire-to-wire
short. The SIGA-IM module monitors line voltages and opens
the data line when a short is detected, isolating the short
between the two modules located electrically closest to the
short
The SIGA-IM module requires one detector address on the
signaling line circuit (SLC). Addresses are assigned
electronically. There are no address switches
LED provides visible indication of the status of the module
Normal: Green LED flashes
Installation
Install this device in accordance with applicable national and
local codes, ordinances, and regulations such as:
NFPA 72 2013 A single fault on a pathway connected to
the addressable devices shall not ecause the loss of more
than 50 addressable devices
2. NFPA 72 2016 A single fault on a pathway connected to
the addressable devices shall not cause the loss of the devices
In more than one zone
Notes
The module is shipped from the factory as an assembled
unit; it contains no user-serviceable parts and should not
be disassembled
