Fires are merciless and prevention is first. How to check if the smoke alarm is working?
The dry weather in winter is the most fire-prone season of the year.
At 7:50 am on January 6, a fire broke out on the construction site of Aoti West Road and Kunshun Road, Jinan City.
On January 14, at 7:50 in the morning, a fire broke out in the cold storage of the Ginza Shengyang Logistics By-product Wholesale Market, Yaojia Road, Lixia District, Jinan City.
On January 16, a fire broke out in the Shandong Shanfang Technology Market in the northwest of the junction of Shanda Road and Yishou Road in Jinan City at around 7 am.
There have been three fires in Jinan in half a month. Should such frequent fires arouse our reflection? Why do so many fires still occur under the premise that the country emphasizes fire prevention in winter? As we all know, winter production is busy and safety is easy to be overlooked, and winter is the storage season. Whether it is factories, enterprises or households, materials are relatively concentrated. Once a fire occurs, it will cause greater losses.
At present, in order to protect the lives of the people and reduce the serious losses caused by fires, smoke alarms are used everywhere. If an effective smoke alarm is installed, the change in indoor smoke concentration can be detected in time. When the indoor smoke concentration reaches the limit, a local alarm will be issued, and the crowd can be notified to open the fire water valve in time before the fire has spread. , In the early stage of the fire, the fire can be controlled in time, and the danger can be stifled in the cradle.
For safety reasons, it is recommended to install smoke alarms in every household and environment to prevent fires. And regular maintenance and inspection, in addition to regular maintenance, usually, how should we determine whether the smoke alarm is working? 
1. Regular inspections and patrol inspections to see if the red light on the smoke sensor will flicker. If it does not flash, there is a problem;
2. We can also test with smoke (smoke generator), if If the smoke alarm alarms, it means that the system (including alarms and smoke detectors) is good;
3. If there is an alarm in normal times, but no fire is actually found, it means that the smoke alarm has a problem;
4. Yes, please State-recognized and qualified units conduct inspections once a year, including electrical inspections.
Kenda PeopleSoft smoke alarm is designed with the principle of photoelectric smoke detection, which realizes fire prevention by monitoring the concentration of smoke, and has a 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 smoke sensor
is a smart product with extremely high cost performance. It is unmatched by traditional smoke alarms in both appearance and function. It meets the fire protection GB4715-2005 standard. It adopts imported microprocessor, low power consumption, and no adjustment is required. Stable work, two-way sensor, 360° sensing smoke, fast sensing without false alarms; SMD technology, anti-EMI, RFI interference, to ensure the accuracy of monitoring. It plays an important role in the early detection and notification of fires, preventing or reducing the hazards of fires, and protecting personal and property safety.
The smoke alarm is an indispensable part of the fire protection system for 24-hour real-time monitoring, instant triggering, remote alarm, safety and reliability. Not only in smart home systems, but also in monitoring systems, smart hospitals, smart hotels, smart buildings, smart breeding and other occasions. It is a good helper for fire accident prevention.
