Installation and debugging skills of the building intercom system

装置设备前首要需对单元所有线路进行全面查看，看看是否存在断线或许短路现象。当整个体系的线路没有任何毛病，才能够对讲设备，而且接线的各接点有必要加上焊锡，确保接点安定。

Before the installation of equipment, it is necessary to have a comprehensive look at all the lines of the unit to see if there is any breakage or short circuit. When there is nothing wrong with the wiring of the whole system, it is necessary for the intercom equipment and the connection points to be added with soldering tin to ensure the stability of the connection.

安装楼宇对讲—安装完后，上电调试前的检查

完结对讲设备初步安装后，有必要细心全面查看各个部位的接线正确与否，一旦有一处接错都有可能引起整个体系无法正常作业，影响体系的运用。特别要注意的是，查看电源线是否接错，正负极是否短路，一旦存在这些问题，上电后轻则会焚毁体系及其相关线路的设备，乃至引起火灾，形成严峻的结果。

After the completion of the preliminary installation of the intercom equipment, it is necessary to take a careful and comprehensive view of the correct connection of the parts of the system. Once there is a fault, it may cause the system to be unable to operate normally and affect the application of the system. In particular, check whether the power line is wrong, whether the positive or negative pole is short circuited, once these problems exist, the light will burn up the system and its related equipment, and even cause a fire, forming a severe result.

一、楼宇对讲系统的调试

First, the debugging of the building intercom system

1.在保证线路及接线无误、设备完好的情况下，单元系统上电后即能正常工作。

1. when the line and wiring are correct and the equipment is in good condition, the unit system will be able to work normally after power on.

2.在单元楼调试时，先把门口主机和最低层保护器/解码器及室内机的所有接线连接好，同时将分机的房号按照使用说明编号；上电调试这层系统的工作情况，确认门口主机及底层线路和设备是否属于正常。

2. in the unit building debugging, first connect the door host with the minimum layer protector / decoder and all the wiring of the indoor machine. At the same time, the unit number is numbered according to the usage description; the working condition of this layer system is debugged, and it is confirmed whether the main engine and the bottom line and equipment of the door belong to normal.

3.若正常工作说明门口主机及线路和设备是正常的；接着切断系统电源，再连接好上一层系统的主线路，进行第二层调试（系统接线时一定要断电），依次往上调。

3. if normal work indicates that the main line and equipment of the doorway and equipment are normal; then the power supply of the system is cut off, then the main line of the last layer of system is connected, and the second layer is debugged (the system connection must be cut off), which is up-regulated in turn.

4.在单元楼的调试过程中，必须从底层开始一层一层地往上调试，即把第一层调试完后，再进行第二层的调试，依此一直往上调试，直到整单元调试完毕且能正常工作。

4. during the debugging process of the unit building, it must be debugged from the bottom layer to the top, that is, after the first layer is debugged, then the second layers are debugged, and the debug is all the way up until the whole unit is finished and can work normally.

正常情况下，可通过使用万用表的电压档测量以下几个电压参数判别线路或器材的好坏；

Under normal circumstances, the voltage parameters of the multimeter can be used to measure the following voltage parameters to determine the quality of the line or equipment.

静态时，电源电压及+B对地的电压：12V

Static, power supply voltage and +B to ground voltage: 12V

音频线A2对地的电压：0V

The voltage of the A2 to the ground of the audio line: 0V

数据线P对地的电压：0V

The voltage of the data line P to the ground: 0V

呼通分机后，音频线对地的电压会变化：升至5.6V

After the call extension, the voltage of the audio line will change to 5.6V

同时呼通分机的瞬间在数据线P线上可测量到一个快速变化的脉冲电压0-5V之间变化。

At the same time, a fast changing pulse voltage 0-5V can be measured on the P line of the data line.

5.若整个单元系统的设备都安装完毕且线路接线无误，但上电后不能工作，先断电只留底层的保护器/解码器、室内机与门口主机连接好，即把二层以上的保护器/解码器的总线全拆掉，确认一下门口主机和底层的保护器/解码器及室内机是否正常，若是正常的，故障就出在二层以上的保护器/解码器或室内机，这样就必须逐层查找故障的根源所在。

5. if the equipment of the entire unit system is installed and the line connection is unmistakable, it can not work after power supply. First, the protector / decoder, the indoor machine and the door host are connected to the bottom layer, that is, the bus of the protector / decoder of more than two layers is completely removed, and the protector / decoder and the decoder of the doorway and the bottom are confirmed. If the indoor machine is normal, if it is normal, the fault will be over two layers of protector / decoder or indoor machine, so it is necessary to find the root of the fault layer by layer.

6.遇到上面故障，若是楼层较高的，可采用“黄金分割法”检查故障，就是先断开中间楼层（如20层楼就必须在10层断开）以上的保护器/解码器的总线，恢复接好二层的总线，确认故障具体是出在中间层以下或中间层以上，依此方法就能最快地查出故障根源点。

6. when the above fault is encountered, if the floor is high, the "golden section" can be used to check the fault. It is the bus of the protector / decoder of the middle floor (such as the 20 floor that must be broken in the 10 layer), and the bus of the two layer is resumed to confirm that the fault is specifically below the middle or above the middle layer. The method can detect the root point of the fault in the fastest way.

7.室内机与保护器/解码器之间只要接线无误，在保护器/解码器上与室内机的连接线插上、视频线接好，将分机的房号编好后无需调试就能正常工作。

7. as long as the connection between the interior machine and the protector / decoder is unmistakable, the connection line between the protector / decoder and the indoor machine is inserted and the video line is connected well. It will work normally without debugging.

8.若室内机的影像出现重影或因信号过强在图像上引起扭曲，必须在顶层最后一个保护器/解码器的视频输出端，并接一个大小为75Ω的碳膜电阻，用于衰减/匹配视频信号。

8. if the image of the indoor machine appears or distorts on the image due to too strong signal, the video output of the last protector / decoder in the top layer and a carbon film resistor size of 75 Omega must be used to attenuate / match the video signal.

9.若室内机的影像出现模糊或图像比较白，说明视频信号较弱，此时可通过打开保护器上的视频放大电路调节视频增益；方法是将保护器上并排的3个跳针J1、J2、J3从原来的OFF处拨到ON处即可，同时可通过调节保护器上的2个电位器来调节视频增益的大小及高频信号的大小。具体办法可将分机拿到保护器的旁边接上，一边调节电位器，一边观察图像；一般低层（7层以下）无须打开视频放大电路；高层（20层以上）的也只要打开一个保护器的视频放大电路就可以。

9. if the image of the indoor machine is blurred or the image is white, the video signal is weak. At this time, the video gain can be adjusted by opening the video amplification circuit on the protector. The method is to dial the 3 jumps J1, J2, J3 from the original OFF to ON at the same time by adjusting the 2 potential on the protector. The device adjusts the size of the video gain and the size of the high frequency signal. The specific method can take the machine next to the protector and adjust the potentiometer while observing the image. Generally, the low layer (below 7 layers) does not need to open the video amplification circuit; the high level (more than 20 layers) can also open a video amplification circuit of a protector.

10.门口主机与室内机呼叫通话过程中，若出现刺耳的啸叫声，或出现主机喇叭的声音较小时，可拿一把小一字螺丝刀，对门口主机主板上的电位器VR1、VR2进行喇叭、咪头音量调整。

10. doorway host and indoor machine call in the process of calling, if there is a screeching scream, or the voice of the host horn is smaller, a small screwdriver can be used to trumpet the potentiometer VR1 and VR2 on the main board of the main door of the door, and adjust the volume of the mica head.

二、小区联网的调试

Two. Debugging of community networking

1、在调试整个联网系统之前，必须检查整个联网主干线和各个中继隔离器的接线是否正确，整个联网线各个接点一定要加上焊锡，增加系统运行的可靠性。

1, before debugging the whole network system, it is necessary to check the connection of the whole network trunk line and each relay isolator correctly, and the connection point of the whole network must be added with solder to increase the reliability of the system operation.

2、联网线的屏蔽线在管理机总控室里一定要接在弱电接地点上，确认无误后，才能开始进行整个联网系统的调试。

2, the screen line of the network line must be connected to the weak electric place in the general control room of the management machine. After confirming the error, we can start the debugging of the whole network system.

3、呼叫前必须对每台门口主机的本机号码进行设置，且同一管理机下的各门口主机的号码不能重复，否则门口主机呼叫管理机时，会出现多台门口主机同时被激活通话，造成多台门口主机同时通话而引起啸叫。

3, before the call, the number of the host at each door must be set, and the number of the main host under the same management machine can not be repeated. Otherwise, when the main host calls the management machine, there will be a multi door host at the same time being activated at the same time, causing a number of door hosts to call at the same time and cause screaming.

4、整个联网系统不能工作时，就必须进行检查D1、D2数据线是否接错，特别是与联网线的D1、D2接错，或其中一台中继隔离器的联网线接错，都会引起整个联网系统不工作。

4, the entire network system can not work, it is necessary to check whether the D1, D2 data line is wrong, especially with the network line D1, D2 connection, or one of the relay isolator network line connection error, will cause the whole network system does not work.
