Understanding Magnetic Door Locks
Magnetic locks, also known as maglocks, are access control devices that use electromagnetism to secure doors. Understanding their functionality is crucial before delving into wiring diagrams. These locks offer a secure and efficient way to control entry and exit points.
Basic Principles of Operation
Magnetic locks operate on the principle of electromagnetism. When an electric current passes through the electromagnet within the lock, it generates a strong magnetic field. This field attracts a metal armature plate mounted on the door, creating a powerful bond that keeps the door securely locked. The holding force, often measured in pounds (e.g., 600lbs or 1200lbs), determines the lock’s resistance to forced entry. The strength of the magnetic field is directly proportional to the current applied. When the power is interrupted, the magnetic field disappears, instantly releasing the door for free egress. This fail-safe mechanism is a key safety feature, especially in emergency situations. Proper wiring ensures consistent power supply and reliable operation of the electromagnetic lock system.
Types of Magnetic Locks (Single, Double)
Magnetic locks are available in single and double configurations, designed for different door setups. Single maglocks are used for single doors, featuring one electromagnet and armature plate. Double maglocks, on the other hand, are designed for double doors, employing two electromagnets and corresponding armature plates. Double maglocks provide enhanced security for wider openings. The wiring configurations differ slightly between single and double maglocks, primarily in the power distribution to each electromagnet. Double maglocks often require a fire-rated power supply to ensure fail-safe operation during emergencies. The choice between single and double maglocks depends on the specific door type, security requirements, and access control system integration. Correct wiring diagrams are essential for both types to guarantee proper functionality.
Components of a Magnetic Lock System
A magnetic lock system comprises a magnet, armature plate, and power supply. It also includes access control integration components like keypads and sensors. Proper wiring ensures seamless operation and security. These parts are essential.
Magnet and Armature Plate
The magnet, a core component, mounts to the door frame, while the armature plate attaches to the door. When energized, the magnet creates a strong attractive force, holding the armature plate securely. This physical connection is critical for the lock’s effectiveness.
Proper alignment and secure mounting of both the magnet and armature plate are essential for reliable operation. Gaps or misalignment can significantly reduce the holding force, compromising security. The armature plate must be able to make full contact with the magnet surface.
The quality of the magnet material and the design of the armature plate influence the overall strength and durability of the magnetic lock; Regular inspection and maintenance are recommended.
Power Supply (12VDC/24VDC)
The power supply is a critical element, providing the necessary voltage to energize the magnetic lock. Most magnetic locks operate on either 12VDC or 24VDC, and selecting the correct voltage is crucial for proper function and to prevent damage.
The power supply must be rated to deliver sufficient current to the magnetic lock. Insufficient current can lead to weak holding force or failure to engage. Fire-rated power supplies are often required to ensure the lock fails unlocked in case of a fire.
The wiring from the power supply to the magnetic lock must be of adequate gauge to handle the current draw. Over longer distances, voltage drop can occur, so thicker wires may be needed. Proper installation is essential.
Access Control System Integration
Integrating magnetic locks with an access control system enhances security and allows for controlled entry. This integration involves connecting the magnetic lock to a controller that manages access based on credentials like keycards, keypads, or biometric readers. The access controller sends a signal to the power supply, which then energizes or de-energizes the magnetic lock.
The wiring diagram is crucial for connecting the access control system to the magnetic lock. The access controller typically has relay outputs that control the power to the lock. The wiring must be done correctly to ensure the lock operates as intended.
Additionally, door position sensors (DPS) can be integrated to monitor door status and provide feedback to the access control system.

The standard wiring configuration for a single door maglock typically involves connecting the maglock to a power supply, often 12VDC or 24VDC. This setup usually includes a connection to an access control system, such as a keypad or card reader, to control the lock’s activation. The power supply provides the necessary current to energize the magnet, creating a strong holding force that secures the door. A basic diagram will show the positive and negative terminals of the power supply connected to the corresponding terminals on the magnetic lock. Additionally, the access control device is integrated into the circuit to interrupt or allow power flow to the maglock, thereby controlling the door’s locked or unlocked state. Proper grounding is essential for safety and optimal performance. This standard setup is foundational for more complex configurations.
Wiring with Keypad and Push Button
Integrating a keypad and push button into a magnetic lock system offers enhanced access control. The keypad allows entry via a numerical code, while the push button provides an egress option from inside. The wiring diagram illustrates how both devices connect to the power supply and maglock. Typically, the keypad’s relay output is wired in series with the push button. When the correct code is entered, the keypad’s relay closes, allowing power to flow to the maglock, unlocking the door. Simultaneously, pressing the push button bypasses the keypad, directly interrupting power to the maglock for immediate release. This configuration ensures secure entry and convenient exit. Fire-rated power supplies are often used to ensure the door unlocks in case of a power outage. A proper installation is essential for safety and reliability.
Wiring with Door Position Sensor (DPS)
Incorporating a Door Position Sensor (DPS) into a magnetic lock system enhances security monitoring. The DPS indicates whether the door is open or closed, providing real-time status to the access control system. A typical wiring diagram shows the DPS connected to the access controller’s input. When the door is closed, the DPS sends a signal indicating a secure state; when the door is open, the signal changes, triggering an alert or logging the event. The DPS is wired in a normally closed (NC) or normally open (NO) configuration, depending on the system requirements. This integration allows for immediate notification of unauthorized door openings or failures to close properly. Furthermore, the DPS helps in managing energy consumption by integrating with building management systems. Accurate wiring is vital for reliable DPS operation and comprehensive security.
