Introduction
This smart smoke detector utilizes low-power Zigbee wireless network technology. Upon detecting smoke reaching a threshold level, the alarm emits high-decibel sounds with a rapidly flashing red LED indicator, alerting the user and their family promptly. Alarm messages are also sent to the user's application in real-time.

Setup
1. Battery Installation
The smoke detector uses one CR123A lithium battery. Ensure the battery is correctly inserted according to the polarity markings inside the battery compartment. The battery is typically pre-installed or included in the package.
Figure 3: Battery Compartment and Battery Life. This image displays the underside of the smoke detector, indicating where the replaceable CR123A 3V battery is located, which provides approximately 5 years of battery life.
2. Mounting Location
Choose a central location on the ceiling, away from corners, vents, and sources of steam or smoke (e.g., kitchen, bathroom). Avoid placing it in dead air spaces. For optimal coverage, ensure the detector is within 20-50 square meters of the area to be monitored.
3. Installation
- Attach the mounting bracket to the desired ceiling location using the provided screws and anchor bolts.
- Align the smoke detector with the mounting bracket and twist it clockwise until it clicks securely into place.
- After installation, the LED indicator should flash approximately every 53 seconds, confirming the device is active.
4. App Pairing and Network Connection
The detector connects via WiFi and Bluetooth for fast setup and real-time notifications through a compatible smart home application (e.g., Tuya Smart app).
- Download and install the recommended smart home application (e.g., Tuya Smart) on your iOS or Android device.
- Open the app and create an account or log in.
- Follow the in-app instructions to add a new device. The app will typically guide you through connecting the smoke detector to your home WiFi network using Bluetooth for initial pairing.
- Ensure your smartphone is close to the smoke detector and your WiFi network is active during the pairing process.

Operating Instructions
Normal Operation
During normal operation, the LED indicator will flash approximately every 53 seconds, signifying that the detector is powered on and monitoring for smoke.
Alarm Condition
When smoke is detected and reaches the alarm threshold, the device will activate both an acoustic and optical alarm:
- The built-in buzzer will emit a loud, rapid beeping sound (85dB at 3 meters).
- The red LED indicator will flash rapidly.
- A real-time alarm notification will be sent to your paired smartphone application.

Silencing the Alarm via App
In case of a false alarm or after addressing the smoke source, you can silence the alarm directly from your smartphone application.
- Open the smart home application on your smartphone.
- Navigate to the smoke detector's device page.
- Look for an option to "Silence Alarm" or "Mute". Confirm the action within the app.

Low Battery Warning
When the battery level is low, the detector will provide a warning. This typically involves a distinct chirp sound and/or a specific LED flash pattern, along with a notification to your smartphone app. Replace the battery immediately upon receiving this warning.
Maintenance
Testing the Detector
Test your smoke detector weekly to ensure it is functioning correctly. Press and hold the test button on the device until the alarm sounds. The alarm should be loud and clear. If the alarm does not sound, refer to the Troubleshooting section.
Cleaning the Detector
Dust and debris can accumulate on the smoke detector, potentially affecting its performance. Clean the detector at least once a month:
- Gently vacuum the exterior of the detector using a soft brush attachment.
- Wipe the exterior with a clean, damp cloth. Do not use cleaning solvents or chemicals.
- Do not open the detector's casing for cleaning.
Battery Replacement
The CR123A lithium battery has an estimated life of 5 years. Replace the battery immediately when the low battery warning is indicated.
- Twist the smoke detector counter-clockwise to remove it from its mounting bracket.
- Open the battery compartment.
- Remove the old CR123A battery and dispose of it according to local regulations.
- Insert a new CR123A lithium battery, ensuring correct polarity.
- Close the battery compartment and reattach the detector to its mounting bracket by twisting clockwise until secure.
