Purchase of smoke detector

The function of the smoke detector is to trigger and start the emergency device, but it can only work when used with other equipment at the same time. The detector must be installed and designed according to the Chinese national standard GBJ116.

Smoke detectors cannot work without power. After losing power for any reason, smoke detectors powered by AC or DC will not work.

The smoke detector cannot detect a fire where smoke cannot reach the detector. The fire generated in the chimney, in the wall, on the roof, or on the other side of the closed door will not reach the smoke detector and cause the alarm.

The detector may not detect fires on other floors of the building. Therefore, each floor of the building should be equipped with detectors.

Smoke detectors also have detection limitations. Ion-type detectors have a wide range of fire detection functions, but their slow, smoldering fires are better at detecting fast-burning and open flame fires. The photoelectric detector has better detection effect on smoldering fires than on bright fireworks. Because the development of fire varies, and its spread is often unpredictable, there is no single detector that always works best. For a certain detector, there is no guarantee that it will always generate a timely alarm for any kind of fire. In general, fires caused by inadequate precautions, violent explosions, leaked gas, poor storage of flammable liquids such as cleaning thinners, and other safety accidents or arson or children ’s fires cannot The detector is expected to give an alarm in time. Smoke detectors used in high wind speed Zhihe will postpone the report due to frequent and just-like air exchanges diluting the concentration of smoke. In addition, the high wind speed environment will produce greater dust pollution and require frequent maintenance.

The smoke detector cannot have an unlimited life. In order to keep the business in a good working state, the equipment should be continuously maintained according to the manufacturer's recommendations and relevant national standards and regulations, and specific maintenance measures should be arranged for different environmental conditions. There are electronic components in the smoke detector. Although the detector has a long design life, there is a possibility of failure at any time. Therefore, the detector should be tested at least once every six months in accordance with relevant national standards or regulations. Any smoke detector, fire alarm device or any component in the system must be repaired or replaced as soon as possible as long as it fails.
