It has a radiation source 241 inside and outside the ionization chamber. The positive and negative ions generated by the ionization move to the positive and negative electrodes respectively under the action of the electric field. Under normal circumstances, the current and voltage inside and outside the ionization chamber are stable. Once smoke escapes the ionization chamber. Interfering with the normal movement of charged particles, the current and voltage will change, and the balance between the internal and external ionization chambers will be disrupted. Therefore, the wireless transmitter sends out a wireless alarm signal to notify the remote receiving host to transmit the alarm information.
The smoke detector uses a photoelectric sensor with a special structure design and SMD chip processing technology. It has high sensitivity, stability and reliability, low power consumption, beautiful and durable, and easy to use. The circuit and power supply can be self-tested and simulated alarm tests can be performed.
This product is suitable for fire alarm in homes, shops, song and dance halls, warehouses and other places. The fire process is generally accompanied by three combustion products: smoke, heat and light. At the beginning of the fire, due to the low temperature, the material is mostly in the smoldering stage, so a large amount of smoke is generated. Smoke is one of the important features of early fires. Smoke-sensing fire detectors are developed using this feature and can respond to visible or invisible smoke particles. It is a device that converts the change in smoke concentration at the detection site into an electrical signal to achieve the purpose of alarm.
