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 far as possible. 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 - 40 KHz. A special loudspeaker with vaulted aluminium dome membrane has been built in to achieve a better sound distribution. A stabilised power supply 12 V/DC (< 60 mA) is necessary for setting into operation. Up to 4 additional loudspeakers Kemo L001 (built-in loudspeaker) or L002 (on-wall loudspeaker) may be connected, if larger rooms (> 30 m²) shall be exposed to ultrasonic waves. Available accessories:
L001 - Piezo spherical dome tweeter with flare
L002 - Ultrasonic wall loudspeaker
P5123 - Mini piezoelectric tweeter for M094N
