7. Operating Instructions
7.1 NC Mode (Fail-Safe) Operation
In NC (Normally Closed) mode, the lock is engaged and secures the door when power is supplied. To unlock the door, the power to the lock must be temporarily interrupted or a signal from an access control device (e.g., push button, remote controller, keypad) must be received to release the bolt.
7.2 Time Delay Function
The lock features an adjustable time delay for unlocking. This delay can be set to 0 seconds, 3 seconds, or 6 seconds. This function allows for a brief period before the door can be opened after an unlock signal is received, which can be useful in certain access control scenarios.
To adjust the time delay:
- Locate the small switch or jumper settings on the side of the lock unit, typically labeled '0SEC', '3SEC', '6SEC'.
- Use a small tool (e.g., screwdriver) to set the switch to the desired delay time.

8. Maintenance
- Regularly inspect the lock and strike plate for any signs of wear or damage.
- Keep the lock mechanism clean and free from dust and debris.
- Ensure all wiring connections remain secure.
- Do not lubricate the internal mechanism unless specifically instructed by the manufacturer.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lock does not engage (stay locked) | No power or insufficient power supply. Incorrect wiring. Faulty lock unit. | Check power supply (DC 12V). Verify wiring connections (Red to +12V, Black to GND). Test with a known good power supply. If problem persists, contact support. |
| Lock does not disengage (unlock) | No unlock signal from access control. Incorrect wiring. Mechanical obstruction. | Ensure access control system is sending an unlock signal. Check wiring for the unlock signal. Inspect for any physical obstructions preventing the bolt from retracting. |
| Time delay not functioning correctly | Incorrect time delay setting. | Verify the time delay switch setting on the lock unit (0s, 3s, or 6s). |
