The relatively simple wiring method is on the switch. Generally, there are two terminals: the L terminal is directly connected to the live wire, the N terminal is connected to one end of the lighting lamp, and the other end of the lamp is connected to the zero wire.
Four-wire acousto-optic switch wiring: black, red, white and green, red is connected to the input live wire, black is connected to the input neutral wire and the output common * * * wire, white output is not connected to the green live wire.
Three-wire acousto-optic switch wiring: the color of the wire may be different from that of the manufacturer. The normal rule is that one is the zero line (blue), one is connected to the load (yellow) and the other is connected to the fire line (red).
Five-wire acousto-optic control switch wiring: one group of incoming fire-fighting zero lines, and one group of outgoing fire-fighting zero lines are connected with light bulbs. Fire service hotline. The incoming and outgoing lines of the zero line actually come from the same inside.
An electronic control method, acousto-optic controlled delay switch refers to an electronic control switch that uses the change of sound and light to control the circuit to achieve specific functions.
Acousto-optic control refers to an electronic control method that uses the change of sound and light to control the circuit to realize specific functions. Acousto-optic controlled delay segment lamp circuit includes sound control, light control sensor, amplifier, monostable time circuit composed of 555 and buck rectifier circuit.
It is an energy-saving electronic switch with no internal contact, which uses acoustic effect to excite the pickup to carry out acoustic-electrical conversion to control the electrical appliance to turn on, and can automatically disconnect the power supply after delay. Widely used in corridors, building corridors, bathrooms, toilets, factories, courtyards and other places, it is a modern ideal new green lighting switch, which prolongs the service life of light bulbs.
During the day or when the light is strong, the circuit is turned off and the light is not on. When the light is dim or the night comes, the switch enters the preparatory working state. At this time, when people have sound sources such as footsteps, voices, clapping, etc., the switch will automatically turn on and the light will light up.
And the automatic delay circuit is triggered, and it goes out automatically after a certain delay, thus realizing "turning on the light when people come, and turning off the light when people leave", eliminating the ever-burning lamp and avoiding the trouble of finding a switch in the dark, especially the inconvenience caused by going up and down the corridor.
