NORMALLY CLOSED (NC MAGNETIC LOCK)

Normally Closed MAGNETIC LOCK

Wiring a normally closed circuit with a magnetic lock (Maglock) involves connecting the components so that the circuit is normally closed, meaning that the electricity flows through the circuit when the maglock is in its default, locked state. When the maglock is deactivated, the circuit opens, interrupting the flow of electricity. This setup is common for security applications, where you want the door to remain locked unless an access control system triggers it to unlock.

Here's a step-by-step guide to wire a normally closed circuit with a maglock:

Materials you'll need:**

1. Magnetic Lock (Maglock): This is the device that secures the door and can be unlocked when needed.

2. Power Supply: To provide power to the maglock.

3. Access Control System (optional): This could be a keypad, card reader, or any other means of controlling when the maglock is unlocked.

4. Wire: Appropriate gauge wire for your setup (usually low voltage).

5. Electric Drill (if you need to drill holes for mounting).

Instructions:**

1. **Mount the Maglock:**

• First, mount the maglock on the door frame or the door itself. Follow the manufacturer's instructions for proper placement and secure it in place.

2. **Connect the Maglock to Power Supply:**

• Maglocks typically require low voltage DC power. Connect one wire from the power supply to the "Positive" terminal on the maglock.
• Connect the other wire from the power supply to the "Negative" terminal on the maglock. This will provide power to the maglock, keeping it locked when the circuit is closed.

3. **Access Control System (optional):**

• If you are using an access control system, connect it to the maglock. The access control system should have a relay or output that can control the maglock.
• Connect one wire from the access control system's relay to one side of the circuit (commonly the "Positive" side).
• Connect the other wire from the access control system's relay to the remaining side of the circuit (commonly the "Negative" side).

4. **Test the Circuit:**

• Before sealing everything up, test the circuit. When power is applied, the maglock should lock the door. If you're using an access control system, use it to test the unlock functionality.

5. **Secure the Wiring:**

• Once you've tested the system and everything is working as expected, secure the wiring to prevent accidental disconnection.

Remember that it's essential to follow the manufacturer's instructions for your specific maglock, power supply, and access control system, as the exact wiring details may vary between different models and brands. Additionally, ensure that your installation complies with local electrical and safety codes.
