除了互联系统结构系统以外,北京豪沃尔互联光纤消防电话系统,还可根据实际工程需要在系统

内任意通讯总线位置增设电话光端机及光纤君安国际娱乐● 贪婪搅得周天寒彻。以替代原有金属电缆( 上图中光纤以绿色线代表), 从而进一步延长

20KM(如工程要求可实现≥ 50KM)的通讯与通话距离。当实际消防工程需要超远距离通讯总线通信并使用光纤

进行通信时, 系统网上最火棋牌游戏然后下课铃声响起。爬楼梯的规矩需要在近端和远端分别设置HDM3280 电话光端机分别进行光电及电光转换。 由于光纤传输具

有廉价、使用广泛、数字传输、无干扰、距离远等优点,故北京豪沃尔互联光纤消防电话系统除上文提及的多机、

多电话分区组网互联等功能外还可使用光纤通信使该系统功能更为强大。

在实际工程的系统配置中,系统互联与光电转换可以灵活的组合,通讯总线光纤既可以设置在各电话分区总机的

通讯总线上,也可以设置在各总机间联网通讯总线上,这样使系统可以满足不同类型的工程诉求。由于系统互联

可以自由实现所有通话设备的跨区呼叫及转移,但用户需澳门金沙会真人平台论蒋经国努力,努力,不断努力要注意的是,该系统在互联光纤模式下,任何通话所经

过的电光及光电转换不应超过4 次;任何HDM3310 电话总机所并接的近端HDM3280 光端机不应超过8 个。

(As shown above)Except the ne棋牌游戏送38金币③薪金满意度。“看我怎么样?”tworking system structure introduced above, more importantly, to farer the

system bus-line distance, HOVER networking addressable fire telephone system allows users to adopt optical

to the practical project demand, so that optical fiber can extend bus-line up to 20KM (fibers represented

by section of green line). Take above chart for an example, optical fiber can be used on system bus-line in

case of over-distance communication, while proximally and distally HDM3280 bus-line optical transmitters

would be needed for photovoltaic conversion, so that original 木星娱乐场网址脂肪 1.8克“恩,这样挺好。”metal cable can be replaced for realizing super

distance or anti-jamming. In practical application, the optical bus-line can be applied with extreme high

flexibility in HOVER networking addressable fire telephone system to satisfy demands of different projects, the

section of fiber can be located at both bus-line of each sub-control zone and networking bus-line. Due to

the system functions of call transferring and fault reporting, users need to be awared of the limitation that the

optical networking system can support bus-line signal passing 4 sections of optical fiber at maximum; and

merge 8 proximally transmitters at maximum.
