    1. Smart fire alarm with infrared photoelectric sensor/explosion-proof certification/network output
    2. The photoelectric smoke alarm detection range is wide, and when a small fire is detected, the alarm will be called immediately to extinguish the fire in the bud.
    3. This hard wired smoke detectors work on the principle of sensing smoke particles. Unique structural design and light.
    4. The electric signal processing technology has the functions of dustproof, insectproof, anti-interference of external light, etc. And the stability of the product is guaranteed from the design.  
    5. Fire smoke detector has a good response to the visible smoke produced by slow smoldering or open burning.
    6. Fire detector with intelligent logic control, SMT process design, strong stability, intelligent logic control, filter out various false alarms, anti-white light interference design, metal shielding cover, anti-radio frequency dry (20v/m-1GHz).


    Tips: What are the types of fire smoke alarm?

    1. The ionization smoke detector is mainly composed of two ionization chambers inside and outside. The outer ionization chamber (the detection chamber) has a hole that communicates with the outside world, and the smoke can enter the sensor through the hole; the inner ionization chamber (the compensation chamber) is sealed, and the smoke cannot enter. When a fire occurs, smoke particles enter the outer ionization chamber, which interferes with the normal operation of charged particles, changes the current and voltage, and destroys the balance between the inner and outer ionization chambers, and the detector will generate an induction and send out an alarm signal.
    2. There is a light-emitting element and a photosensitive element inside the photoelectric smoke detector. Usually, the light emitted by the light-emitting element is emitted to the photosensitive element through the lens, and the circuit remains normal. If there is smoke blocking it, the light reaching the photosensitive element will be obviously weakened, so the photosensitive element converts the change of light intensity into a change of current, and sends out an alarm signal through the amplifying circuit.
    3. The aspirating smoke detector has changed the traditional way of waiting for the smoke to drift to the detector to detect passively, but adopts a new concept, that is to say, to actively sample and detect the air. The aspirating pump inside the gas-type smoke detector sucks into the sampling pipe and sends it to the detector for analysis. If smoke particles are found, an alarm will be issued.
