What is the condition of a smoke alarm at home every few seconds?
From the internal principle, the smoke alarm is through the monitoring of the concentration of smoke to achieve fire prevention, such as Langxin smoke alarm internal use of ion smoke sensor, it is a technologically advanced, stable and reliable sensor, is widely Applied to a variety of fire alarm system, the performance is far better than the smoke resistance of the fire alarm.
Smoke alarm, also known as fire smoke alarm, smoke sensors, smoke sensors and so on. The general will be independent, physical product battery-powered, or AC power supply for the preparation of electricity, ready-made alarm when the sound and light can be issued, known as the independent smoke alarm. By the bus power supply, the bus can be connected to more than one, and the fire alarm controller networking, communication composed of an alarm system, the alarm when the scene without sound, the host has sound and light tips, such smoke alarm device is generally known as smoke detection Device. Smoke Detector with address code, without address code.
It is inside and outside the ionization chamber inside the radioactive source americium 241, ionization generated positive and negative ions, under the action of the electric field to the positive and negative electrodes to move. Under normal circumstances, both inside and outside the ionization chamber current, voltage is stable. Once there is smoke to flee outside the ionization chamber. Interference with the normal movement of charged particles, the current, the voltage will change, undermine the balance between the internal and external ionization chamber, so the wireless transmitter to send a wireless alarm signal, notify the remote receiving host, the alarm information will be passed out.
