Frequently Asked Questions
Q: What app does the SN-9134 BLE lock module work with?
A: The SN-9134 is designed to work exclusively with the TTLock App, available for both iOS and Android. Through the app, you can unlock doors, assign access to multiple users, set timed access schedules, and review entry logs.
Q: What voltage does the SN-9134 BLE lock module require?
A: The module requires a DC supply voltage between 8V and 18V. Always ensure your power supply falls within this range — too low may cause the module to malfunction, and too high can permanently damage it.
Q: Can I use this module with normally closed (NC) door locks?
A: Yes. The SN-9134 includes a relay with NO (Normally Open), NC (Normally Closed), and COM (Common) terminals, making it compatible with a wide range of electric door locks, strikes, and magnetic locks in both normally open and normally closed configurations.
Q: What is the Bluetooth range of the SN-9134 module?
A: 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.
Q: Does the module consume a lot of power when idle?
A: No. The SN-9134 is designed to remain in a low-power sleep state when not in use. It only activates when an unlock signal is sent via the TTLock App, keeping energy consumption minimal.
