Precautions for using smoke sensor:

1, the alarm should be dustproof, and the dust cover must be removed after the project is officially put into use;

2. When installed on the roof, if it is installed on an inclined or humanoid roof, the alarm should keep a certain distance from the roof. When the slope is less than 30, the spacing is 0.2m, and when it is greater than 30, the spacing is 0.3m~0.5m:

3. Under normal circumstances, do not install it in a smoky place. Smoke alarm is highly sensitive to smoke, so it is likely to give a false alarm in places that are prone to smoke, such as kitchens and smoking places.

4. Avoid installation in places with a lot of dust, water mist, steam, oil mist pollution and corrosive gases;

5. The temperature and humidity of the working environment of the smoke alarm should not exceed-10~50℃, and should not be installed in places with relative humidity greater than 95% and ventilation speed greater than 5m/s;

6. Avoid installation near fluorescent lamps;

7. It is suggested to conduct a simulated fire alarm test every six months to test whether the alarm works normally;

8. Never cover the smoke alarm with adhesive tape or plastic bag.
