4. Product Overview
4.1. Wi-Fi Loudspeaker Siren
The siren is the central unit of your security system. It emits a loud 110 dB alarm when triggered and connects to your home Wi-Fi network for app control and notifications. It is designed to be weatherproof for indoor or outdoor use.

4.2. Door/Window Alarm Sensor
This two-part sensor detects when a door or window is opened. When triggered, it sends a signal to the siren, activating the alarm and sending a notification to your smartphone.


4.3. Remote Controller
The remote controller allows you to arm, disarm, set home mode, or trigger an SOS alarm with the press of a button.

5. Setup
5.1. Powering On the Siren

- Plug the power adapter into a standard electrical outlet. The siren will power on.
5.2. App Installation
Download and install the Tuya Smart or Smart Life app from your device's app store (Android or iOS).
5.3. Network Configuration (Wi-Fi Loudspeaker Siren)
Before configuring the network, ensure:
- Your Wi-Fi network is 2.4 GHz. The alarm horn is not compatible with 5G Wi-Fi.
- Bluetooth is enabled on your smartphone.
- Location services are enabled for the Tuya Smart app in your phone's privacy settings.
- Open the Tuya Smart app and log in or register.
- On the app's home screen, tap "Add Device" or the "+" icon.
- Long press the [SET Key] on the Wi-Fi loudspeaker siren for 3 seconds until it sounds, indicating it has entered network configuration mode.
- The app will scan for nearby devices using Bluetooth. Once the "WiFi loudspeakers" device is found, tap "Add".
- Enter your 2.4 GHz Wi-Fi network name and password when prompted.
- Follow the on-screen instructions to complete the pairing process.
5.4. Installing Door/Window Sensors
- Ensure the door/window sensor has its 23A 12V battery installed.
- Identify a suitable location on your door or window frame. The two parts of the sensor must be aligned and within 1 cm of each other when the door/window is closed.
- Clean the surface thoroughly.
- Attach the larger part (transmitter) to the fixed frame and the smaller part (magnet) to the moving part of the door/window using the provided double-sided adhesive tape.
- Test the sensor by opening and closing the door/window to ensure proper alignment.

6. Operating the System
6.1. Arming and Disarming
You can arm or disarm your security system using the Tuya Smart app or the remote controller.
- Away Arm: All sensors are monitored. Ideal when no one is home.
- Home Arm: Only specific sensors (e.g., perimeter sensors) are monitored, allowing movement within the home.
- Disarm: All sensors are disabled.
6.2. Alarm Notifications
When a sensor is triggered, the 110 dB siren will sound, and you will receive instant notifications on your smartphone via the Tuya Smart app.


6.3. Voice Control (Alexa & Google Assistant)
The system is compatible with Amazon Alexa and Google Assistant, allowing you to arm, disarm, or set home mode using voice commands.

7. Expanding Your System
The TOWODE security system is scalable, supporting up to 50 remote controls and 50 additional sensors. These can include motion sensors, water leakage sensors, and smoke sensors (Wireless Frequency: 433MHz, Wireless Code: eV1527).


8. Maintenance
8.1. Battery Replacement (Door/Window Sensor)
The door/window sensor is powered by a 23A 12V battery. When the low voltage indicator light on the sensor illuminates, it is time to replace the battery.
- Carefully open the sensor casing.
- Remove the old 23A 12V battery.
- Insert a new 23A 12V battery, ensuring correct polarity.
- Close the sensor casing securely.
