Introduce the principle of wireless smoke detectors
    Smoke detectors is by monitoring the concentration of smoke to achieve fire prevention, smoke alarms inside the ion type smoke sensor, ion type smoke sensor is a technologically advanced, stable and reliable sensors are widely applied to various fire alarm system, the performance is far superior gas sensing alarm fire resistance class. Following on from the Operations Research science and technology skill for everyone to explain the principles of smoke detectors. 

       Technical principle: smoke detectors inside and outside the ionization chamber americium 241 radioactive sources inside the ionization produced by positive and negative ions, each moving to the positive and negative electrodes under the influence of an electric field. Under normal circumstances, both inside and outside the ionization chamber current, voltage is stable. Once outside the ionization chamber smoke Cuantao. It interferes with the normal movement of charged particles, current, voltage will be changed, destroyed the balance between inside and outside of the ionization chamber, so the wireless transmitter emits a wireless alarm signal to inform the distant receiving host, pass out the alarm message. 

    Features: high reliability, frequency stability, strong anti-interference, low power consumption, easy installation, ceiling installation, attractive appearance, 360-degree azimuth detection.
       Applications: less smoke, smoking places smoke-ion detection; suitable for use with most weak control system, also equipped with the best products and intelligent home security host.
    Technical parameters: Power: DC9 volt alkaline battery or carbon battery; Working Current: small quiescent current 10uA, alarm working between the current 10-30mA; output: Wireless signal transmission, 868MHz or 433MHz; smoke sensitivity: comply with UL217 sensor no standard; working environment: temperature -5 ℃ -50 ℃, humidity 10-90% non-condensing; buzzer sound level intensity: 10 feet more than 85 decibels; battery life: about 1 year, when over-voltage detector is low, it will emit a short cry about every minute to remind the user to replace the battery
