    Q1: What is a smoke detector?
    A smoke detector is a typical device converted from space fire protection measures to civilian use. The smoke detector mainly realizes fire prevention by monitoring the concentration of smoke. The smoke detector adopts ion-type smoke sensor. The ion-type smoke sensor is a kind of advanced technology, stable and reliable sensor, which is widely used in various daily life. Its performance is far better than that of gas-sensitive resistance fire alarms.

    Q2: How does a smoke detector work?
    A2: The infrared beam of the infrared emission tube is dispersed by the smoke particles, and the intensity of the scattered light is proportional to the smoke concentration. Therefore, the intensity of the infrared beam received by the photosensitive tube will change, and it will be converted into a point signal, which will eventually become an alarm signal.

    Q3: What does a smoke detector do?
    A3: Smoke detectors assemble sensors, control assemblies, and alarm notifications. Therefore, this is a collection of multi-functional detector in one, is the most suitable for residential. Once the smoke detector is triggered, the device sends a signal to the audio-visual notification device, which will issue an alarm. Inside the smoke detector, you'll find a power source and a built-in sensor that can react to the smoke in different ways.

    Tips: Where should the CO and smoke detector be installed?

    • In the kitchen, it is recommended to install the smoke alarm 3 meters away from the cooking utensils.
    • In the sleeping area, install a smoke detector within 4.5 meters so that everyone can hear the siren, even if the bedroom door is closed.
    • For single-story homes: Smoke detector should be installed in hallways, between sleeping and living areas. It is best placed on the ceiling, at least 30 cm away from walls or lamps.
    • For large-scale or multi-storey residences: in addition to the above-mentioned single-storey residence installation locations, the bottom of the stairs and the stair connection on each floor should be added. Also consider buying interconnected alarms so that smoke or heat detected on one floor can trigger alarms throughout the house.
