This ultrasonic generator produces pulsating and aggressive ultrasonic sounds like a siren, which many animals perceive as extremely unpleasant and therefore try to avoid as much as possible. The generator is used to protect against rodents, insects, reptiles, crawling creatures, wildlife, and birds, etc. Kemo M071N allows for adjustable operation (frequency/interval), which prevents animals from getting used to the sound over time. By adjusting the operation, the long-term effectiveness of the protection is increased, as animals cannot predict the constant repetition of the same signal. The frequency of the generator is adjustable between approx. 8 - 40 KHz. For better sound distribution, a special speaker with a curved aluminum membrane is built-in. A stabilized power supply of 12 V / DC (<60 mA) is required for operation. Up to 4 additional Kemo L001 (built-in speaker) or L002 (wall speaker) can be connected if larger rooms (> 30 m²) are exposed to ultrasonic waves.
