Door Strike Wiring Diagram: An Essential Guide for DIY Enthusiasts

The door strike is a critical component of any access control system that is used for securing doors in commercial, residential, or industrial buildings. If you are a DIY enthusiast and want to install a door strike, it is essential to understand the wiring diagram. In this article, we’ll provide you with a comprehensive guide on door strike wiring that will help you install the door strike securely and efficiently.

What is a Door Strike?

A door strike is an electric lock that can be installed on the door to provide access control. It works with a latch and deadbolt mechanism to lock and unlock the door. The door strike is connected to a power source and a control system to receive the signals for locking or unlocking the door. The control system can be a keypad, card reader, or any other access control device.

A door strike can be of different types based on its mechanism and installation. The most common types are:

Type Features
Magnetic Low power consumption, high security
Electric Easy to install, compatible with different access control systems
Mechanical Hard to break, suitable for outdoor installation

Door Strike Wiring Diagram

The wiring diagram of a door strike is not complicated, but it requires attention and accuracy to ensure a successful installation. The diagram consists of four main components:

  • Power supply
  • Control system
  • Door strike
  • Electric strike release

Let’s discuss each component and their wiring in detail:

Power Supply

The power supply is the main source that provides electricity to the door strike. It can be an AC adapter or a battery. The most common voltage range for a door strike power supply is between 12VDC and 24VDC.

The wiring of the power supply is straightforward. Connect the positive and negative wires of the power supply to the corresponding terminals of the control system.

Control System

The control system is the brain of the access control system. It receives the input from the user and sends the signal to the door strike to lock or unlock the door. The control system can be a keypad, card reader, or any other access control device.

The wiring of the control system depends on the type and model of the device. However, the basic wiring is the same for all devices. Connect the positive and negative wires of the control system to the corresponding terminals of the power supply.

Door Strike

The door strike is the electric lock that is installed on the door. It receives the signal from the control system to lock or unlock the door. The door strike can be magnetic, electric, or mechanical, as discussed earlier.

The wiring of the door strike is the same for all types. Connect the positive and negative wires of the door strike to the corresponding terminals of the electric strike release.

Electric Strike Release

The electric strike release is a safety mechanism that releases the door strike when there is an emergency, such as a fire or power outage. The electric strike release is connected to the power supply and the door strike. In case of an emergency, the electric strike release disconnects the power supply from the door strike, allowing the door to open freely.

Frequently Asked Questions

What is the voltage range for a door strike power supply?

The most common voltage range for a door strike power supply is between 12VDC and 24VDC.

What type of control system is suitable for a door strike?

Any access control device, such as a keypad, card reader, or biometric scanner, is suitable for a door strike.

Can I install a door strike on an exterior door?

Yes, you can install a door strike on an exterior door. However, you should choose a mechanical door strike that is hard to break and can withstand harsh weather conditions.

What is the difference between a magnetic and electric door strike?

A magnetic door strike uses a magnetic field to lock and unlock the door, while an electric door strike uses a solenoid to move the latch and lock the door. A magnetic door strike is more secure and consumes less power than an electric door strike.

How can I troubleshoot a door strike wiring problem?

If you encounter any wiring problems with the door strike, you can check the wiring diagram and ensure that all wires are connected correctly. You can also use a multimeter to check the voltage and continuity of the wires.

In conclusion, understanding the wiring diagram of a door strike is crucial for a successful installation. Make sure to follow the wiring instructions carefully and double-check the connections to avoid any potential problems. With this article’s help, you will be able to install a door strike confidently and securely.
