无线楼宇对讲机
南京小丁数码科技有限公司开发的国内首款 无线楼宇对讲系统。你可以看看
选楼宇对讲是有线的好用还是无线的好用啊,求大神指教!!!
之前在楼宇对讲的厂里面做过,个人建议还是选择有线的吧,修起来方便不说,成本还少很多,而且稳定。无线的虽然安装方便,用起来很高大上,但是真的出问题了很麻烦,一不小心就是系统不稳定,锁不了门,开不了门啥的情况一大堆,特别是楼层一高,问题就更明显了。
楼宇对讲室内分机接线 ***
两线分机,不区分线序,1、红黄,黑黄,红黑等挨个试一下。2、顺着8芯入户线往楼下捋线,在楼道的楼宇对讲弱电箱内有个楼层解码器,看一下1248跳下,算一下自己家对应的户,看排序上是哪两根,自己家就接那两根。
2.A.B是对讲通话线,C是地线,这三根是所有分机通用的,下面两排1——7是响铃线,每户人家单独一根。在家里你要分出哪三根是通用的,而且要一一对应,不能接错,第四就接响铃线。
对讲机的英文名称是 two way radio,它是一种双向移动通信工具,在不需要任何 *** 支持的情况下,就可以通话,没有话费产生,适用于相对固定且频繁通话的场合。对讲机有三大类:模拟对讲机、数字对讲机、IP对讲机。
对讲机涵盖范围较宽。在这里我们将工作在超短波频段(VHF 30 ~ 300 MHz、UHF 300~3000 MHz)的无线电通信设备都统称为无线电对讲机,实际上按国家的有关标准应称为超短波调频无线 *** 机。人们通常将功率小、体积小的手持式无线 *** 机叫做“对讲机”,以前曾有人称它为“步谈机”、“步话机”;而将功率大、体积较大的可装在车(船)等交通工具或固定使用的无线 *** 机叫做“电台”,如车载台(车载机)、船用台、固定台、基地台、中转台等。
