What is the working principle of an independent smoke detector? Can the fire alarm system manufacturer provide you with specific information?

Smoke rises and reaches below the ceiling. The smoke detector detects a fire through smoke. When you haven't seen any flames or smelled smoke, the smoke detector already knows. It works non-stop, 365 days a year, 24 hours a day, without interruption. When the alarm is triggered, it emits a sharp and piercing sound until the smoke dissipates. In a real fire, it worked until it was burned down.

There are two types of sensors available for independent smoke detectors in residential buildings: ion sensors and photoelectric sensors. The mainstream technology in the industry now is photoelectric sensors.

Photoelectric sensors measure the concentration of smoke through a beam of light and a sensor of light. When designing this device, the beam deviated from the sensor. When smoke enters the sensing chamber, smoke particles will scatter some of the light beam onto the sensor. As the concentration of smoke gradually increases, more light beams will be scattered onto the sensors. When the beam of light reaching the sensor reaches a certain level, the buzzer will sound.

Is using a smoke detector effective?

With the increasing number of users of smoke detectors, the number of deaths caused by residential fires is also decreasing. The report from the National Fire Protection Association of the United States indicates that homes equipped with recommended smoke detectors will have a 50% higher chance of escape for occupants in the event of a fire compared to homes that have not been installed.

Which type of smoke detector is better?

The appearance and parameters of detectors from different brands vary, each with its own unique features. But when choosing an independent smoke detection alarm, it is important to pay attention to whether the product has obtained 3C certification. Of course, choosing a professional brand will give you more peace of mind.

What methods can I use to detect smoke detectors?

Each smoke detector is equipped with a detection button after production. The manufacturer suggests that it is best for everyone to regularly check their alarm, at least once a month.
