Smoke detector is mainly through monitoring the concentration of smoke to achieve fire prevention, smoke detector internal use of ion smoke sensing, ion smoke sensor is a technology-advanced, stable and reliable sensor, widely used in a variety of fire alarm systems, performance is far better than the gas resistance of the fire alarm.
The smoke detector has a radioactive source in the internal and external ionization chamber, the positive and negative ions produced by ionization, which move to the positive and negative electrodes under the action of the electric field. Under normal circumstances, the current and voltage of the internal and external ionization chamber are stable. Once there is smoke running away from the ionizing chamber. Interference with the normal movement of charged particles, current, voltage will change, destroying the balance between the internal and external ionization chamber, so the wireless transmitter issued a wireless alarm signal, notify the distant receiving host, the alarm information will be transmitted.
There are 4 conductor sheets on the base of the smoke detector, with terminals on the sheet, and no position card is set on the base, which facilitates the adjustment of the direction of the detector alarm confirmation lamp. The detector bus in the wiring tube is connected to two terminals at any diagonal angle (regardless of polarity), and another pair of conductor sheets are used to assist in fixing the detector.
In short, smoke detectors in life is relatively common, to our lives have brought a lot of convenient places, for the maintenance of our security has played a very good role in safeguarding, let us improve its process.
