The main features of the electronic fence: a safe and reliable maintenance elevator monitoring system uses high-voltage, low-energy design ideas, the human body does not constitute a hazard to life. 2, high and low voltage switchable mode: Users can switch modes depending on the freedom needs. During the day or in the vicinity of the fence who switched jobs to low-voltage mode, the front fence of the pulse can reduce the crackdown; high alert during the night time or need, can be restored to a high voltage pulse mode. Currently, many hosts are equipped with electronic fence set up to monitor maintenance quote after switching time, the machine automatically switches high and low voltage function. 3, you can use SMS to remotely arm, disarm operation. 4, there is linkage output interface monitoring maintenance, with monitor, alarm center to achieve linkage function. Network computer monitoring can also be achieved. 5, with a custom-made batteries, will continue to work in case of power failure, after the call is automatically converted into a 220V power supply. 6, electronic cables as part of a perimeter fence, so you can reduce the cost of construction projects to reduce investment. 7, the electronic fence also has a beautiful appearance, easy installation and maintenance, simple cell monitoring maintenance, not the terrain restrictions, low cost. Replacement of equipment maintenance service in line to replace the content consists of a replacement, alarm equipment, monitoring software maintenance, DVR equipment and ancillary equipment maintenance. Maintenance service mode 1, the control room computer room environment. 2, the device operating environment. 3, the installation location of all equipment operation. 4, line usage and line laying the path alignment methods. 5, line all interfaces, all the video head, terminal line contacts are secure. 6, software usage, software upgrades. 7, the system data backup situation. In the above work in the implementation process requires the user to provide the appropriate system wiring diagram, standoff point distribution, monitoring point distribution, as well as assist the relevant personnel.
