Frequently Asked Questions
Q: What is the TTLock SN-9243 Bluetooth lock module and what does it do?
A: The Asia-Teco SN-9243 is a Bluetooth 5.0 BLE smart lock control module that converts a standard electric door lock into a smartphone-controlled smart lock. It communicates with the TTLock App on Android or iOS, allowing you to unlock, issue digital keys, monitor access logs, and manage your lock remotely when paired with the G2 WiFi Gateway.
Q: Do I need the G2 Gateway to use this module?
A: No — the G2 Gateway is optional. Without it, you can unlock and manage the lock via Bluetooth when your phone is within range. Adding the G2 Gateway enables remote WiFi control from anywhere in the world and unlocks voice control via Amazon Alexa or Google Assistant.
Q: What batteries does the SN-9243 use, and how long do they last?
A: The module is powered by 4 standard alkaline dry cell batteries. Thanks to the ultra-low standby current of just 37 µA, battery life is optimized for long-term use. The app will send a low-battery alert when voltage drops to 4.8 V so you can replace them before they run out.
Q: Can I set time-limited access for guests or tenants?
A: Yes. The TTLock App allows administrators to issue digital keys with a defined validity window (start date/time to end date/time). You can also freeze or revoke a key at any time, giving you full control over who can access your property and when.
Q: Is this module compatible with smart home platforms?
A: Yes. When connected to the TTLock G2 WiFi Gateway, the SN-9243 integrates with Amazon Alexa and Google Assistant, enabling voice-activated lock control as part of your broader smart home setup.
