Magnetic door locks are so common that you can see them applied everywhere: offices, hospitals, factories, shopping malls, stores, subways, etc.
They’re greatly accepted by most markets all over the world because of easy installation, comprehensive compatibility, multiple holding force grades, and various optional functions. All these features make electromagnetic locks the critical part of access control solutions.
The electromagnetic lock is simple to function with a power supply, as the fail-safe electric lock.
For the BASIC MODEL of electric magnetic lock without any optional function, and with single voltage, like 12VDC, the wiring diagram for magnetic door lock is simple.
Required materials:
• DC power supply or adapter
• Magnetic door lock
Operation:
- Connect the positive wire of the maglock (For TOPLOCK magnetic door lock, it’s red) to the “+12V” pole of the power supply.
- Link the negative wire (For TOPLOCK maglock, it’s black) to the “GDN” pole.
- The electric circuit loop is formed. The magnetic door lock can perform normally by connecting and disconnecting the wires to the power supply.
The wiring diagram for magnetic door lock should be as follows:

If the electric magnetic door lock is designed with 12VDC/24VDC interchangeable, for instance, TOPLOCK’s magnetic locks, you need to short-circuit some internal circuitry to achieve it.
Operations:
- For the magnetic lock PCB with the dual voltages, to use 12VDC, you need to cover all the four jumpers, then connect the wires of the maglock like the OPERATION for the “BASIC MODEL” as mentioned above. Jumpers of TOPLOCK magnetic door locks with dual voltages are all well covered when they leave the factory.
2. Regarding the 24VDC of the electric magnetic lock with the dual voltages, you need to cover the two middle jumpers among the four, before linking the wires as mentioned above.

Instead of being used alone, in most practical cases, the electro magnetic locks are compatible with the access control keypads or door bells (from outdoor side), exit switches/buttons (from indoor side), break emergency glass releases (for emergency exits from indoor side), and so forth. Maglock can work with either one or more of the abovementioned devices to make up an access control system.
Wiring Diagram For Magnetic Door Lock With Access Control Keypad
Required materials:
• DC power supply or adapter
• Magnetic door lock
• Access control keypad/reader
• Doorbell (if the access control keypad allows for it)
From outdoors, the magnetic door lock kit is workable with the access control keypad for entrance. Nowadays access control keypads can provide various ways of opening, take TOPLOCK access keypads or readers as an example. They offer the password, pin code, fingerprint, RFID card, and so on for opening. That means, the electric magnetic lock has quite a few of opening ways correspondingly, so it becomes one of the most popular electric locking devices for access control solutions.
Moreover, if the access control keypad allows for a doorbell, electronic magnetic lock can also work with it. Below is the wiring diagram for magnetic door lock with the access keypad:

Wiring Diagram For Magnetic Door Lock With Exit Switch/Button
Required materials:
• DC power supply or adapter
• Magnetic door lock
• Exit switch/button
Since the magnetic door lock kit has no bolt or latch, an exit switch/button can be added to control the electric power which is supplied to the maglock, in order to make it convenient for people’s egress.
With the exit switch/button, the wiring diagram for magnetic door lock should be as follows:

Wiring Diagram For Magnetic Door Lock With Break Glass Emergency Release
Required materials:
• DC power supply or adapter
• Magnetic door lock
• Break glass emergency release
• Alarm (if needed)
The reason why electronic magnetic door locks are widely used in emergency exits or fire exits is that they can collaborate with break-glass emergency releases, call points, fire alarms, and the like. Electromagnetic locks play an important role in fire alarm systems.
You can check the following wiring diagram for magnetic door lock with the break glass emergency release, as an example.

The above illustrations are for standard electromagnetic locks without additional functions. However, to facilitate the magnetic door locks perform better with access control solutions, experienced manufacturers like TOPLOCK design more functions with maglocks, such as feedback signal output, time delay, buzzer alarming. Among them, time delay and buzzer alarm require the corresponding electronics (timer & buzzer) to function, while feedback signal output should be achieved by the specific electro circuit.
Such additional functions don’t conflict with the said access control devices, on the contrary, they support each other to build up a comprehensive access control system to fulfill the multiple functions. You can refer to the following wiring diagram for magnetic door lock with varied devices.

In a word, magnetic door lock is so versatile that you should take it into account for your residential, commercial, or industrial applications. Selecting a professional and reliable manufacturer you can get the quality magnetic door locks with reasonable prices. TOPLOCK can help you on electric magnetic locks as well as other electric locks. You can trust them, as they have been focusing on the electric locks for over 17 years. Kindly talk further with TOPLOCK: www.toplocksecurity.com.
