KEMO Marderschreck, Ultraschall

To repel martens in cars, houses, etc. Produces aggressive ultrasonic
sounds inaudible to men, which martens find very annoying and try to
avoid if possible. May be mounted at the entrance holes of the cars.
Through the water and dirt resistance, this Marten Device can be mounted on the cars initial openings directly.

*
IP 65:No penetration of dust at a low pressure of 20 mbar in the case,
protected against hose-water from every direction against the case
(corresponds to 12.5 ltr./minute e.g. garden hose, test period:approx. 5
minutes, information without engagement).

TECHNICAL DATA
Features splash-proof / 2-fold effectiveness ultrasound + pulsating light
Operating voltage 11 - 15 V/DC (car battery)
Sealing
splash-proof case,
according to IP65* (can be mounted at the entrance holes of the motor
vehicle)
Switch-on function soft start so that the vehicle computer will not be disturbed
Average power consumption < 2 mA
Ultrasonic frequency approx. 23 kHz +/- 15%
Angle of radiation ultrasound approx. 160°
Acoustic
pressure approx. 150 dB (+/- 20%)
(Ultrasonic devices should have a sound pressure level exceeding 100 dB
(C) to avoid habituation
(ADAC test results)).
Sound Sine, aggressively pulsating
Loudspeaker
impact sound generator,
which makes the upper side oscillate (splash-proof)
Optical determent pulsating LED (serves as functional display at the same time)
Temperature range approx. -25° C to + 80° C
Voltage
peaks secured against voltage
peaks in the vehicle power supply to 40 V ( < 20 ms)
Fuse in the fuse holder F500 mA
Dimensions approx. 58 x 38 x 31 mm (without fastening straps)
CAN data bus suitable for vehicles with CAN data bus.

Why
does the device have no frequency change? Martens and other small
predators emit short and intensi warning cries, no siren sounds! Our
anti-marten device imitates these tones very naturally and is,
therefore, optimal to scare away martens.
