Analysis: "wired door magnet" in the use of anti-theft and access control system
"Door Magnetic Switch" in the security industry is generally used in anti-theft systems and access control systems, installed in the doors and windows of an intrusion detector. Security industry commonly known as "door magnet", security national standard CNCA-10C-047: 2009 "security technology to prevent the implementation of mandatory certification rules for the implementation of product certification intrusion detector products," the standard named "Magnetic Switch". Magnetic switch according to the type of supporting host is divided into wired door magnet and wireless door magnet, this paper does not talk about wireless door magnet.
1.0 Output signal of wired door magnet
Wired door magnet consists of reed switch and permanent magnet two parts, wired door magnet is basically compatible with all types of wired host, to achieve the intrusion detection of doors and windows. Door magnet is a switching signal, the door open and close triggered by the door magnet signal on and off, the door magnet output signal is divided into normally closed, normally open, and conversion type.
1.1 Normally Closed Door Magnet: When the door or window is normally closed, the permanent magnet and the reed switch are close to each other, and the magnetic field generated by the permanent magnet will absorb the contacts of the reed switch to form a closed state. If the door or window is opened illegally, the permanent magnet will be far away from the reed switch, and the magnetic field around the reed switch will disappear to cause the contacts to be disconnected, and the signal will be disconnected to trigger an alarm, which is usually called the disconnection alarm. Normally closed door magnet affordable, the market used the most.
1.2 Normally open door magnet: when the door or window is normally closed, the door magnet output signal is disconnected, when the door or window is opened illegally, the door magnet output signal is connected to trigger the alarm, called the pass-through alarm. The internal structure of the reed switch in the door magnet is more complex, the cost is also higher market use is relatively less.
1.3 conversion type door magnet: as the name suggests, the conversion type door magnet taking into account the characteristics of normally closed and normally open the door magnet, where it can be compatible with all the wired anti-theft alarm host.

Magnetic Reed Switches vs. Reed Switches: Understanding the Difference Have you ever been confused when buying a door magnetic switch? There are two common types of door magnetic switches on the market: reed switches and reed switches. They look similar, but there are actually some important differences. Let's take a look at these two types of door magnetic switches so you can make an informed choice. First, let's focus on reed switches. Reed switches use a reed and a magnet to sense when a door is open or closed. When the door is closed, the magnet moves closer to the reed, causing it to close, which triggers the switch. And when the door is open, the distance between the magnet and the reed increases and the switch breaks. This design makes the reed switch very sensitive and responsive. In contrast, the reed switch uses a different principle of operation. It consists of a glass tube containing a steel reed inside a magnetic material. When the door is closed, the reed makes contact with the magnetic material, causing the reed switch to close. When the door is opened, the magnetic material loses its attraction and the reed springs open, disconnecting the switch. The advantage of the reed switch is its long life and ability to withstand higher current loads. So how do you choose the right door magnetic switch for you? It depends on your specific needs. If you're focused on responsiveness and sensitivity, then a reed switch may be more suitable for
Wireless Door Magnets vs. Wired Door Magnets: which one is better for you Door Magnetic Switches are a common security device widely used in homes, businesses and industries to monitor the status of doors and windows. When choosing a door magnet switch, many people are faced with a decision: to choose a wireless door magnet or a wired door magnet? This article will explore the advantages and disadvantages of both types of door magnet switches to help you make a more informed choice. Wireless door magnet refers to the door magnet switch that does not need to be connected by wires and transmits door and window status information through wireless signals. It features easy installation and simple maintenance. Since wireless door magnet does not need to lay wires, it can save time and cost during the installation process. At the same time, the wireless door magnet can monitor the status of doors and windows anytime and anywhere, and can receive information even at locations far away from the door magnet. This makes it ideal for remote monitoring and security systems. However, wired door magnets also have their own unique advantages over wireless door magnets. Wired door magnets transmit door and window status information to the main controller via a wire, which is more stable and reliable than wired door magnets. As wired door magnets are connected by wires, they are not affected by signal interference and there is no need to worry about signal loss or interference. At the same time, wired door magnets can be integrated with other security devices, such as alarm systems and surveillance systems.

How to Choose the Right Door Magnetic Switch for Your Home Door magnetic switches are a common home security device used to detect the opening and closing of doors and windows. Choosing the right door magnetic switch for your home is very important to improve your home security and comfort. In this article, we will explore how to choose the right door magnetic switch for your home and provide you with some suggestions. Firstly, consider the location of the installation when choosing a door magnetic switch. Door magnetic switches are often fitted to the frame of windows and doors, so you need to make sure that you choose a door magnetic switch that can accommodate different types of windows and doors. For example, for aluminium windows and doors, you could choose a magnetic door magnet switch, which attaches magnetically to the window or door, eliminating the need to drill holes for installation. For wooden doors and windows, you can choose sensor type door magnetic switch, which can detect the opening and closing status of doors and windows through sensors. Secondly, the sensitivity of the door magnetic switch is also an important factor to choose. The sensitivity of the door magnetic switch determines its ability to detect changes in the status of the door or window. If you have children or pets at home, you may need to choose a more sensitive door magnetic switch to detect their activities in time. In addition, some door magnetic switches have an adjustable sensitivity feature that you can adjust according to your actual needs. In addition, the communication method of the door magnetic switch also needs to be considered. Modern door magnetic switches
Applications for Door Magnetic Switches: Securing Your Home Home security is very important to everyone. We all want to feel safe and secure in our homes. A magnetic door switch is a very effective device that can help us achieve this. In this article, we will look at the application of door magnetic switches and how it can keep your home safe. A door magnetic switch is an on/off device that is installed on doors and windows. It consists of two parts: one mounted on the door frame and the other on the door. When the door is closed, the two parts come together and trigger the switch, sending out a signal. When the door is opened, the two parts separate and the switch breaks the signal. This signal can be connected to your home's security system, such as an alarm system or surveillance system, to sound an alarm in the event of an unauthorised entry. Door magnetic switches have a wide range of applications. It can be used in homes, commercial premises, or anywhere security is required. In homes, door magnetic switches can be used on front doors, back doors, windows, etc. to help you monitor the security of your home in real time. When someone tries to enter illegally, the door magnetic switch will immediately trigger an alarm to scare away potential intruders and notify you or security personnel. In addition to securing your home, door magnetic switches can also be used in other scenarios. For example, access to shops or offices
Magnetic switches: what they are and how they work Have you ever thought that many devices in our daily life use magnetic switches? For example, our refrigerators, washing machines, televisions and so on. So, what is a magnetic switch? How does it work? Let's find out together. A magnetic switch, also known as a door magnetic switch, is a device that uses magnetic materials and electrical principles to achieve the switching function. It usually consists of a magnet made of magnetic material and an electromagnet wound with a coil. When the magnetic switch is in the closed state, attraction occurs between the magnet and the electromagnet, causing the circuit to close and current to flow; while when the magnetic switch is in the open state, the magnetic force between the magnet and the electromagnet disappears, the circuit breaks, and current stops flowing. So how does a magnetic switch work? Let's explain it through a concrete example. Suppose you have a door magnetic switch installed in your room. When you open the door, the magnetic switch senses the state of the door and transmits the signal to the relevant equipment, such as light or air conditioner. When you close the door, the magnetic switch also senses it and passes the signal to the devices, causing them to stop working. In this way, we can achieve intelligent control through magnetic switches. The working principle of door magnetic switch
