Many electric locks have many other connections besides the power interface line. Among them, the lock status line and the door status line should be specially concerned. The lock status connection can provide the lock information of the lock, and can be linked with the digital input interface of the access control system. View the closed state of the lock in real time. The door state connection is a good alternative to the problem of separately installing the door magnet, which reduces the installation cost, improves the system use efficiency, and better guarantees the aesthetic appearance of the building decoration.
Open and close delay settings
Many electric locks have a special delay setting jumper or dialing device, which can set the delay time of the electric lock. However, most access control and intercom systems also have a delay setting function, so it must be considered when installing the electric lock. Delay setting.
Electric lock power supply
There are many types of electric locks, there will be some differences in current and voltage, and the number of electric locks managed by each access controller will be more. At present, many low-end and mid-range access control products will directly supply power to the electric lock. I believe that this is not the case. It is recommended that the power supply configuration of the access controller is often configured according to the load of the controller itself. If the electric lock is driven, the controller may be unstable or even damaged. Secondly, the distance between the electric lock and the access controller is also With uncertainty, long-distance power supply may also cause the electric lock to work abnormally. Third, the frequent opening and closing of the electric lock during use may cause instability of the current and voltage. If it is directly powered by the controller, this current Fluctuations in voltage can cause damage to the controller, which is unforgivable regardless of the value of the equipment or the level of security. It is recommended that regardless of the size of the system, the electric lock power supply must be configured separately, and regardless of the control mode of the access control and intercom system, it is recommended to use the relay isolation mode for the electric lock opening and closing control to ensure the maximum between the electric lock current and the control host current. Isolated.
ECO application
At present, one of the more popular system inspection indicators is ECO, which is the so-called environmental protection, energy saving, and ecological application. The power consumption of a single electric lock may be very inconspicuous in the eyes of users and engineering companies, but in the face of large-scale intelligent buildings. For hundreds or even thousands of electric lock applications, the power consumption of the electric lock is not a small number. Therefore, in the electric lock application of the building intelligent system, the ECO index can not be ignored from the perspective of operating cost and environmental protection. .
Mosquito screens have become an essential tool in the battle against these pesky and disease-carrying insects. These screens are specifically designed to keep mosquitoes out while allowing fresh air and natural light to flow through. Made from a fine mesh material, mosquito screens effectively create a barrier that prevents mosquitoes from entering indoor spaces. Whether installed on windows, doors, or even outdoor areas, mosquito screens provide a reliable defense against these bothersome insects, allowing you to enjoy a peaceful and uninterrupted environment. With their easy installation and low maintenance requirements, mosquito screens offer a practical and effective solution for protecting yourself and your loved ones from mosquito-borne diseases.
