Figure 2: Door handing guide. 1 = Right Internal, 2 = Left Internal, 3 = Right External, 4 = Left External. This diagram helps determine the correct orientation for the lock's installation based on how the door opens and from which side it is viewed.
- Right Internal: Door opens inwards, hinges on the right when viewed from the inside.
- Left Internal: Door opens inwards, hinges on the left when viewed from the inside.
- Right External: Door opens outwards, hinges on the right when viewed from the outside.
- Left External: Door opens outwards, hinges on the left when viewed from the outside.
6. Setup and Installation
Installation should be performed by a competent individual. Ensure all safety precautions are followed.
- Prepare the Door: Mark the desired position for the lock body on the door. Ensure it is at a comfortable height and allows for proper clearance.
- Drill Mounting Holes: Using the provided template (if applicable) or the dimensions from Figure 1, drill pilot holes for the lock body and the external cylinder (if used). Ensure holes are straight and of the correct diameter.
- Install External Cylinder: If your model includes an external cylinder, insert it through the door and secure it according to its specific instructions.
- Mount Lock Body: Position the main lock body on the door, aligning it with the drilled holes. Secure it firmly with the provided screws. Do not overtighten.
- Install Strike Plate: Close the door and mark the position for the strike plate on the door frame, ensuring it aligns perfectly with the lock's bolt. Mount the strike plate securely.
- Electrical Connection: Connect the lock to the power supply and access control system (if applicable) according to the wiring diagram provided with your specific model. Ensure correct polarity and voltage. This step must be performed by a qualified electrician.
- Test Functionality: Before fully securing all covers, test the lock's operation with both the key and the electrical impulse. Ensure the bolt extends and retracts smoothly and the door latches correctly.
7. Operating Instructions
- Manual Operation (Key): Insert the key into the external cylinder and turn it to unlock or lock the door.
- Electric Operation: When an electrical impulse is applied (e.g., from an intercom or access control system), the lock's bolt will retract, allowing the door to be opened. The lock will automatically re-engage when the door is closed, or the impulse is removed, depending on the specific wiring configuration.
- Internal Button/Lever: If your model includes an internal button or lever, it can be used to open the door from the inside without a key or electrical impulse.
8. Maintenance
- Cleaning: Clean the exterior of the lock with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish.
- Lubrication: Periodically apply a small amount of graphite-based lubricant to the keyway and moving parts of the bolt mechanism to ensure smooth operation. Do not use oil-based lubricants, as they can attract dust and grime.
- Inspection: Regularly check all mounting screws for tightness. Inspect the strike plate for wear and ensure it is securely fastened.
- Electrical Connections: Periodically inspect electrical connections for any signs of wear or corrosion. Ensure they remain secure.
