Installation and use

1、the equipment in the shell of the four sides of the shutter, its ultrasonic radiation in the effective radius, up and down the distance is slightly less than the surrounding area. Effective working radius is 12m-15m, but reached the edge of the radius, the ultrasonic sound pressure has been weakened, the ideal working radius should be within 10 meters. Therefore, in the installation, whether in the substation, or production workshop, storage warehouse should not be placed directly on the ground.

Substation is generally installed 4-8 units is appropriate, in addition to the placement of the location should be considered evenly distributed to cover the corners of the required protection, but also to consider the height of the place to be protected (equipment). The effective working radius of the equipment determines the height of the bird repeller. (If the height to be protected is 20 meters, it is decided that the height of the bird repeller should not be lower than 12 meters). Production workshops and warehouses are generally installed to the upper part.

2、After connecting the power supply, turn on the switch, the indicator light flashes, and emits 6KHz low frequency ultrasonic sound, which lasts for about 10 seconds, while the indicator light flashes at a speed of 1 second, and enters the working state after 10 seconds. Bird repeller normal work indicator state is "light 1 second → extinguish 1 second → light 1 second → extinguish 9 seconds" speed cycle.

3、Frequency is 12KHz～25KHz, adopting two working mechanisms: frequency sweeping and frequency fixing. During normal operation, the bird repeller alternates between 5 minutes of frequency sweeping and 5 minutes of frequency fixing without intermittent operation. Frequency sweeping: that is, in the 12KHz ~ 25KHz band with a cycle speed of 3.8 seconds, constantly changing the frequency of work for 5 minutes. Fixed frequency, that is, between 16KHz ~ 25KHz randomly selected a frequency point to work for 5 minutes. So that birds can not adapt to ensure that ultrasonic bird repeller can be long-term effective bird repellent.
