- Install the electromagnet unit to the inside frame of your door. This will provide a firm and strong mounting point for your locking system. Make sure the electromagnet is installed in a place that has easy access to wiring from the power supply. The power supply will either be a separate unit tapped into your home's electrical system or direct power from the home's wiring. When working with your home's electrical, make sure the circuit you will be altering is turned off at the breaker.
- Install the armature on the door, aligned with the electromagnet. When an electrical signal passes through the electromagnet, a magnetic field is generated that attracts the armature to the electromagnet unit, locking the door. It is important the armature is properly aligned with the magnet. Also, do not install the armature too tightly. Allowing some freedom of movement will help to guarantee proper magnetic contact.
- Connect the power line to one of the terminals on your switching mechanism. This mechanism will allow you to control the lock. It may be a simple pushbutton, a keypad, or a key card reader. Make sure your switch is rated to work with the voltage and amperage of your circuit. Refer to the instructions included with your switch for placement and installation instructions specific to your model.
- Connect a wire from the free terminal of your switch to the positive terminal on the electromagnet. Magnetic locks require either 12 or 24 Volts DC power. Make sure your circuit operates on one of these currents, or you may need to install a DC filter to convert AC power to DC power. Your electromagnet may also need to be jumpered to match the current of your circuit. Refer to your magnet's instructions for information on how to convert it for 12 or 24 VDC operation.
- Connect the negative ground wire to the negative terminal on the electromagnet. This will complete the electrical circuit, allowing the magnet to be engaged or disengaged with the switch.
- Power on your circuit and test that your magnetic lock functions properly. If the lock does not engage, check your wiring to make sure it is correct.
Things You Will Need
- Wire cutters
- Magnetic lock system
- Make sure the armature is properly aligned with the electromagnet. This will have an effect on the strength and security of the magnetic bond.
