Through the app, you can unlock doors, assign access to multiple users, set timed access schedules, and review entry logs.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What voltage does the SN-9134 BLE lock module require?\u003c\/h4\u003e\n\u003cp\u003eA: The module requires a DC supply voltage between \u003cstrong\u003e8V and 18V\u003c\/strong\u003e. Always ensure your power supply falls within this range — too low may cause the module to malfunction, and too high can permanently damage it.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use this module with normally closed (NC) door locks?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The SN-9134 includes a relay with \u003cstrong\u003eNO (Normally Open), NC (Normally Closed), and COM (Common)\u003c\/strong\u003e terminals, making it compatible with a wide range of electric door locks, strikes, and magnetic locks in both normally open and normally closed configurations.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the Bluetooth range of the SN-9134 module?\u003c\/h4\u003e\n\u003cp\u003eA: The module uses Bluetooth 4.0 BLE with a built-in antenna. Typical indoor range is approximately 5–10 meters, though actual performance may vary depending on walls, interference, and environmental conditions.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does the module consume a lot of power when idle?\u003c\/h4\u003e\n\u003cp\u003eA: No. The SN-9134 is designed to remain in a \u003cstrong\u003elow-power sleep state\u003c\/strong\u003e when not in use.
