4. Installation Guide
4.1 Safety Precautions
- Ensure power is disconnected before beginning any installation or wiring.
- Consult a qualified electrician if you are unsure about any wiring procedures.
- Wear appropriate safety gear during installation.
4.2 Magnetic Lock Installation (Outswinging Door)
For outswinging doors, the magnetic lock body is typically mounted on the door frame, and the armature plate is mounted on the door. Z and L brackets are required for proper alignment.
- Mount the L-Bracket: Secure the L-bracket to the door frame using the provided screws. Ensure it is level and positioned correctly for the magnetic lock body.
- Mount the Magnetic Lock Body: Attach the magnetic lock body to the L-bracket.
- Mount the Z-Bracket: Assemble the Z-bracket components and attach them to the door. The Z-bracket allows the armature plate to align with the magnetic lock body.
- Attach the Armature Plate: Secure the armature plate to the Z-bracket. Ensure the armature plate can pivot slightly to allow for full contact with the magnetic lock face.
- Adjust Alignment: Close the door and adjust the position of the magnetic lock and armature plate to ensure full contact and secure locking.
