5. Setup and Installation
5.1 Mounting the Lock
- Prepare the Door and Frame: Identify the desired mounting location on the door frame and the corresponding position on the door for the bolt to engage. The lock is surface-mounted.
- Mark Drilling Points: Use the lock unit as a template to mark the screw holes on both the door frame and the door.
- Drill Pilot Holes: Drill appropriate pilot holes for the mounting screws.
- Secure the Lock: Attach the main lock unit to the door frame and the induction lock component to the door using the provided screws. Ensure proper alignment for smooth bolt operation.
5.2 Wiring Instructions
The electric drop bolt lock requires connection to a DC 12V power supply and an access control system. Refer to the wiring diagram below for proper connections.
- Red Cable: Connect to the +12V terminal of your power supply control.
- Black Cable: Connect to the GND (Ground) terminal of your power supply control.
- Purple Cable: Connect to the NO (Normally Open) terminal in your power supply control or access control panel. This connection is crucial for the Fail-Security (NO Mode) operation.
- Other Cables: Yellow and White cables are typically for door status feedback (NC/COM), which may or may not be used depending on your access control system's requirements. Consult your access control system manual for these connections.

6. Operating Instructions
6.1 NO Mode (Fail-Security) Operation
This electric drop bolt lock operates in NO Mode (Fail-Security). This means:
- When there is no power, or in case of a power failure, the lock remains in a locked state.
- The lock will only unlock when power is supplied to the lock and an authorized signal is received from the access control system (e.g., pressing a push button, using a remote controller, or entering a code on a keypad).
6.2 Time Delay Function
The lock features an adjustable time delay function, which controls how long the door remains unlocked after an authorized signal is received. The delay can be set to 0 seconds, 3 seconds, or 6 seconds.
To adjust the time delay, locate the small switch or jumper on the side of the lock unit (refer to Image 6.1). Move the switch or adjust the jumpers to select the desired delay setting (0s, 3s, or 6s).

7. Maintenance
- Cleaning: Wipe the lock's exterior with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the finish or internal components.
- Inspection: Periodically check all mounting screws to ensure they are tight. Inspect wiring for any signs of wear, fraying, or loose connections.
- Functionality Test: Regularly test the lock's operation with your access control system to ensure it locks and unlocks correctly and that the time delay functions as expected.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lock does not engage (stay locked) | No power to the lock; Incorrect wiring for NO Mode. | Check power supply (DC 12V). Verify Red and Black wire connections. Ensure Purple wire is correctly connected to NO terminal. |
| Lock does not disengage (unlock) | No signal from access control; Insufficient power; Faulty access control component. | Confirm access control system is functioning. Check power supply voltage. Inspect Purple wire connection. |
| Time delay not working correctly | Incorrect time delay setting. | Adjust the time delay switch/jumper on the lock unit to the desired setting (0s, 3s, or 6s). |
| Lock is loose or misaligned | Loose mounting screws; Improper initial installation. | Tighten all mounting screws. If misalignment persists, re-evaluate mounting positions and re-install if necessary. |
