Product Introduction
The WiFi smoke alarm is produced by using infrared photoelectric sensor with special structure design, reliable MCU, and SMT chip processing technology.
It is characterized by high sensitivity, stability and reliability, low power consumption, beauty, durability, and easy-to-use. It is suitable for smoke detection in factories, homes, stores, machine rooms, warehouses and other places.
It is not suitable for use in the following places:
(1) Places with smoke retention under normal conditions.
(2) Places with heavy dust, water mist, steam, oil mist pollution and corrosive gas.
(3) Places with relative humidity greater than 95%.
(4) Places with ventilation speed greater than 5m/s.
(5) The product cannot be installed in the corner of the building.
The alarm adopts a photoelectric sensor with a special structure design and a reliable MCU, which can effectively detect the smoke generated in the initial smoldering stage or after the fire. When the smoke enters the alarm, the light source will produce scattered light, and the receiving element will feel the light intensity (there is a certain linear relationship between the received light intensity and the smoke concentration).
The alarm will continuously collect, analyze and judge the field parameters. When it is confirmed that the light intensity of the field data reaches the predetermined threshold, the red LED light will light up and the buzzer will start to alarm.
When the smoke disappears, the alarm will automatically return to the normal working state.

Installation Instruction
Operation Instructions
Normal state: The red LED lights up once every 56 seconds.
Fault state: When the battery is less than 2.6V ± 0.1V, the red LED lights up once every 56 seconds, and the alarm emits a "DI" sound, indicating that the battery is low.
Alarm status: When the smoke concentration reaches the alarm value, the red LED light flashes and the alarm emits an alarm sound.
Self-check status: The alarm shall be self-checked regularly. When the button is pressed for about 1 second, the red LED light flashes and the alarm emits alarm sound. After waiting for about 15 seconds, the alarm will automatically return to the normal working state.
Silence state: In the alarm state, press the Test/Hush button, and the alarm will enter the silence state, alarming will stop and the red LED light will flash. After the silencing state is maintained for about 15 minutes, the alarm will automatically exit the silencing state. If there is still smoke, it will alarm again.
Warning: The silencing function is a temporary measure taken when someone needs to smoke or other operations may trigger the alarm.
Common Faults And Solution
| Fault | Cause analysis | Solutions |
|---|---|---|
| False alarm | There is a lot of smoke in the room or water vapor | 1. Remove the alarm from ceiling mount. Reinstall after the smoke and steam are eliminated. 2. Install the smoke alarm in a new location. |
| A "DI" sound | Battery is low | Replace the product. |
| No alarm or emit "DI" twice | Circuit failure | Discussing with supplier. |
| No alarm when press Test/Hush button | The power switch is off | Press the power switch on the bottom of the case. |
Low battery warning: When the product emits a "DI" alarm sound and LED light flash every 56 seconds, it indicates that the battery will be depleted.
The low battery warning status can last about 30 days.
The product battery is non-replaceable, so please replace the product as soon as possible.
