Ultrasonic Vermin Repellent

This ultrasonic generator produces pulsating and aggressive ultrasonic sounds like a siren which many animals perceive as extremely unpleasant and, therefore, try to avoid it The generator should be used to keep away rodents, insects, crawling parasites, game and birds, etc.
The frequency of the generator is adjustable between approx. 8 - 40kHz. A special loudspeaker with vaulted aluminium dome membrane has been built in to achieve a better sound distribution. A stabilised power supply 12VDC (< 60mA) is necessary for setting into operation. Up to 4 additional loudspeakers BKM.L001 (built-in loudspeaker) or BKM.L002 (on-wall loudspeaker) can be connected, if larger rooms (> 30m²) have to be exposed to ultrasonic waves.

Adjustable frequency: approx 8 - 40 KHz (± 15%)
Frequency deviation, ca. 2 x per second: 2-3kHz (automatic change of frequency, siren-like)
Sound pressure: max 100dB (± 15%) (Ultrasonic devices should have a sound pressure level exceeding 100dB (C) to avoid habituation (ADAC test results). (Source de.wikipedia.org/wiki/Marderabwehr)
