1. Introduction
This user manual provides comprehensive instructions for the installation, operation, and maintenance of your EMASTIFF W7B Smart Home Alarm System. This system is a dual-network security solution utilizing both Wi-Fi and cellular (GSM/4G) connectivity, designed to provide robust home security.
The system supports up to 100 wireless sensors, 10 remote tags, and 10 RFID tags, offering flexible customization for various security needs. It integrates with the Tuya Smart Life app for convenient remote control and monitoring.


2. Setup
2.1 Before You Begin
For a successful setup, please ensure the following:
- If using a 4G SIM card, verify that your wireless service provider's 2G network is available in your country. If not, consider a 4G cellular communicator hub.
- For Wi-Fi models, select a 2.4GHz Wi-Fi network. The hub does not support 5GHz Wi-Fi.
- Your Wi-Fi password must not contain spaces or other special characters.
- Place the hub as close as possible to your router.
- A minimum upload speed of 2Mbps is recommended for optimal performance.
- Disable AP isolation in your router settings.
2.2 What You Need
To set up and use the Alarm System, you will need:
- An iPhone or Android phone.
- The Smart Security System app (downloadable via QR code or app store).
- An unused indoor power outlet.

4. Maintenance
4.1 Battery Backup
The Smart Hub includes a built-in backup battery (3.7V, 500mAh Rechargeable Lithium Battery) that provides power for over 3 hours in case of electrical outage. The battery icon on the display shows the charge level. If the backup battery is very low, the icon turns red, and low battery notifications will be sent to registered phone numbers. A full charge takes 8 to 12 hours.
4.2 Sensor Battery Replacement
Regularly check the battery status of your wireless sensors. Replace batteries as needed to ensure continuous protection.
- Door/Window Sensor: Uses CR2032 3V battery.
- PIR Motion Sensor: Uses 2*AA batteries or a 9V battery.
- Remote Control: Uses 12V27A or CR2032 3V battery.
4.3 Cleaning
Wipe the hub and sensors with a soft, dry cloth. Do not use liquid cleaners or abrasive materials, as they may damage the devices.
5. Troubleshooting
- No Cellular Network Connection: If the gray cellular icon or 'X' is always shown, ensure the SIM card is properly inserted (when the hub is off) and its security code is deactivated.
- Wi-Fi Connection Issues: Ensure you are connecting to a 2.4GHz Wi-Fi network. Avoid spaces or special characters in your Wi-Fi password. Place the hub close to your router. Disable AP isolation in your router settings.
- Slow Performance: A slow network speed (below 2Mbps upload) can affect hub performance.
- Hardwired Zone Supervision: If using EOLR (End of Line Resistor) for hardwired zones, ensure it is at the end of the loop for proper supervision. Otherwise, the system may not respond to an open circuit.
- Factory Reset Issues: The Smart Hub cannot be reset if it is locked. A factory reset will delete all paired accessories and event logs.
- App Notifications: Ensure the app has permission to receive notifications on your smartphone, especially for notifications, to receive timely alerts.
- European Plug: If you require a European plug, please ensure the correct variant is selected during purchase.
