4. Installation and Setup
Proper installation is crucial for the optimal performance and security of your electric mortise lock. This lock is designed for concealed installation within the door frame.
4.1 Pre-Installation Checks
- Ensure the door type (wooden, metal) is compatible with the lock's dimensions and mounting requirements.
- Verify that the power supply (DC12V or DC24V) matches the lock's requirements.
- Confirm that all necessary tools and components (lock unit, screws, wiring) are available.
4.2 Wiring Instructions
The lock typically has multiple wires for power and control. Refer to the specific wiring diagram provided with your access control system. Generally:
- Connect the Red wire to the positive (+) terminal of the DC power supply.
- Connect the Black wire to the negative (-) terminal of the DC power supply.
- Additional wires (e.g., Yellow and White) are typically for door status feedback (Common and NC contacts) and should be connected to your access control panel or alarm system as required.
4.3 Time Delay Adjustment
The lock features a switch to adjust the locking delay. This delay determines how long the bolt remains retracted after activation before extending to lock the door. This is useful for allowing the door to fully close and settle before locking.
- Locate the small switch or jumpers on the lock unit.
- Set the delay to 0, 3, or 6 seconds according to your application needs. The factory default is usually 0 seconds.

4.4 Mounting the Lock
The lock is designed to be mortised into the door frame or door. Ensure precise alignment between the lock body and the strike plate (if applicable) for smooth operation.
- Carefully measure and mark the installation location on the door frame and door.
- Rout out the necessary cavity for the lock body.
- Secure the lock unit using the provided screws.
- Ensure the magnetic sensor aligns correctly with the corresponding part on the door when closed.

5. Operation
The OBO HANDS Electric Mortise Lock operates based on magnetic induction and its fail-safe design.
5.1 Fail-Safe Mode
This lock is a Fail-Safe (NC) type. This means:
- When power is applied, the lock bolt extends, securing the door.
- When power is removed (e.g., during a power outage or intentional disconnection), the lock bolt retracts, and the door becomes unlocked. This feature is critical for safety in emergency situations, allowing free exit.
5.2 Locking and Unlocking
- Locking: When the door is closed and the magnetic sensor detects proper alignment, applying power to the lock will cause the bolt to extend and secure the door after the set time delay.
- Unlocking: To unlock the door, power to the lock must be interrupted. This is typically done via an access control system (e.g., card reader, push button, remote control) which momentarily cuts power to the lock, causing the bolt to retract.
5.3 Testing the Lock
When testing the lock outside of a door installation, it is important to simulate the closed-door condition for the magnetic sensor to engage. Place two pieces of iron or a suitable magnetic material together on the lock's sensor area to activate the magnetic force and allow the bolt to extend.
6. Maintenance
The OBO HANDS Electric Mortise Lock is designed for low maintenance. Regular checks can help ensure its longevity and reliable operation.
- Cleaning: Keep the lock body and magnetic sensor free from dust and debris. Use a soft, dry cloth for cleaning. Avoid abrasive cleaners or solvents.
- Connections: Periodically inspect wiring connections to ensure they are secure and free from corrosion.
- Alignment: Check the door and frame alignment to ensure the lock bolt and magnetic sensor engage smoothly without obstruction or excessive friction. Misalignment can cause premature wear or operational issues.
- Lubrication: The internal mechanism is generally self-lubricating. Avoid applying oil or grease unless specifically recommended by the manufacturer for a particular issue.
7. Troubleshooting
If you encounter issues with your electric mortise lock, refer to the following common problems and solutions:
- Lock does not engage/disengage:
- Check power supply: Ensure the lock is receiving the correct DC12V/DC24V power.
- Verify wiring: Confirm all wires are correctly connected and secure.
- Check magnetic sensor: Ensure the door is fully closed and the magnetic sensor is properly aligned and engaged. The lock requires the magnetic sensor to detect closure before the bolt will extend.
- Inspect for obstructions: Look for any physical obstructions preventing the bolt from extending or retracting.
- Lock is stuck or difficult to operate:
- Check door alignment: Misalignment can cause the bolt to bind. Adjust the door or lock position if necessary.
- Examine the bolt: Ensure the bolt itself is not damaged or bent.
- Avoid side loading: The lock's pin is not designed for significant side loading. Ensure the door closes squarely onto the lock.
- Unexpected unlocking (Fail-Safe behavior):
- This is normal operation for a Fail-Safe lock. If power is lost, the lock will unlock. If you require the door to remain locked during a power outage, a Fail-Secure lock type is needed, or a backup power supply (UPS) for your access control system.
