What's the smoke alarm in the house every few seconds?
From the internal principle, the smoke alarm is by monitoring the concentration of smoke to achieve fire prevention, such as internal Long Xin smoke alarm by ion type smoke sensor, it is a kind of advanced technology, stable and reliable operation of the sensor, is widely used in all kinds of fire alarm system, fire alarm performance is far better than the gas sensing resistance type.
A hint of electricity.Smoke alarms, another name for fire smoke detectors, smoke sensors, smoke sensors, etc.. In general, an independent, physical product, battery powered, or alternating current power supply, the battery for the preparation of electricity, the alarm can be issued when the sound and light instructions, known as independent smoke alarm. By bus power supply, the bus can be connected with a plurality of fire alarm controller, and the communication network, composed of an alarm system, police at the scene when the host has no sound, sound and light tips, the smoke alarm device commonly known as smoke detector. The smoke detector is encoded with address without address.
It inside and outside the ionization chamber inside the radioactive americium 241, positive and negative ion generation, under the electric field respectively to the positive and negative electrode movement. Under normal conditions, the internal and external ionization chambers are stable in both current and voltage. Once a smoke Cuantao outside the ionization chamber. Interfere with the normal movement of charged particle current, voltage will change, destroy the balance between internal and external ionization chamber, and a wireless transmitter sends wireless alarm signal to the receiving host notification from afar, the alarm message.
