Renke RS-YG-N01 smoke alarm adopts photoelectric smoke sensing principle design, built-in smoke sensor, and photoelectric smoke device. Smoke moves upwards. When it rises to the bottom of the ceiling and enters the inside of the alarm, the smoke particles will scatter part of the light beam to the photosensitive element. The denser the smoke, the more light is scattered on the photosensitive element. When the light beam scattered on the sensor reaches a certain level, the buzzer will sound an alarm. At the same time, the sensor converts the light signal into an electric signal and transmits it to the automatic fire alarm system to prompt a fire.
The stand-alone smoke alarm has the characteristics of precise measurement, sensitive response, and high stability; it complies with the fire protection GB4715-2005 standard, adopts ceiling-mounted installation, does not require debugging, and can detect fire in 360 degrees; adopts patch technology to resist EMI The interference effect of RFI, once the “signal” of the burning of the object is “captured”, the signal will be uploaded to the fire fighting system to ensure the continuity of information transmission.
According to statistics, with smoke alarms, the proportion of casualties and property losses caused by fires has been greatly reduced. The National Fire Protection Association report shows that once a fire occurs in a house with a smoke alarm, the chances of escape for people in the house will be 50% higher than that of a house that is not installed. Therefore, it is necessary to install an alarm at home.
How to install smoke alarm?
1. Choose a suitable installation location, usually on the ceiling in the middle of the room.
2.The power input can be 10~30V. 485 When wiring the signal line, note that the A/B two lines cannot be reversed, and the addresses of multiple devices on the bus cannot conflict.
3 Fix the mounting base on the ceiling with screws.
4. It is recommended to conduct a simulated fire alarm test after installation to test whether the alarm can be used normally.
1. The alarm should be dustproof, and the dust cover must be taken off after the project is officially put into use;
2. When installed on the roof, if it is installed on a sloping or man-shaped roof, the alarm should be kept at a certain distance from the roof. When the slope is less than 30°, the distance is preferably 0.2m, and when the slope is greater than 30°, the distance is 0.3m~0.5m Appropriate;
3. Don’t install in places where smoke stays under normal conditions. Smoke alarms are highly sensitive to smoke. Therefore, it is very likely that the alarm will be falsely alarmed in places that are prone to smoke such as kitchens and smoking places;
4. Avoid installation in places with large dust, water mist, steam, oil mist pollution, and corrosive gas;
5. The temperature and humidity of the working environment of the smoke alarm should not exceed -10~50℃, and avoid installing in places where the relative humidity is greater than 95% and the ventilation speed is greater than 5m/s;
6. Avoid installing near fluorescent lamps;
7. It is recommended to conduct a simulated fire alarm test every six months to test whether the alarm is working properly;
8. Don’t cover the smoke alarm with tape or plastic bags!
