M176 - Marten Defence for Motor Vehicles 12 V/DC, splash-proof with IP 65*
EAR registrated
Marten Defence for Motor Vehicles 12 V/DC, splash-proof with IP 65*
Technical Data
splash-proof | 3-fold effectiveness: ultrasound, electric shock, pulsating light
Operating voltage
12 - 15 V/DC (car battery)
The control unit including the loudspeaker is splash-proof according to IP 65* (it can be mounted at the entrance holes of the motor vehicle.)
Average power consumption
< 5 mA
Switch-on function
soft start so that the vehicle computer will not be disturbed
Automatic switch-off
if the battery voltage decreases to < 11,5 V (± 5%)
Output voltage
approx. 200 - 300 V/DC
Ultrasonic frequency
approx. 22 kHz ± 10%
Acoustic pressure
max. approx. 100 dB ± 20% (Ultrasonic devices should have a sound pressure level exceeding 100 dB (C) to avoid habituation (ADAC test results). (Source
Angle of radiation ultrasound
approx. 160°
impact sound generator, which makes the upper side of the case oscillate (splash-proof)
sine, aggressively pulsating
Temperature range
approx. -25°C to +80°C
Functional display
flashing LED (approx. every 5 - 12 sec.)
Cable length high-voltage cable
approx. 4 m (± 10%)
Fuse in the fuse holder
1 A
High-voltage contact plates
6 pieces, movable, approx. 62 x 42 mm each, stainless steel
Dimensions basic device
approx. 40 x 50 x 70 mm (without cable entry + fastening feet)
Cable for terminal 15
If this cable is connected with „Positive“, the marten defence disconnects. The marten defence switches on if it is connected with “Negative” or does not receive any signal.
CAN data bus
suitable for vehicles with CAN data bus.
Voltage peaks
The device is protected against voltage peaks in the vehicle power supply up to 40 V (< 20 ms).
Optical determent
The built-in pulsating LED unsettles the nocturnal martens in addition.
Why does the device have no frequency change? Answer
Martens and other small predators emit short and intense warning cries, no siren sounds! Our anti-marten device imitates these tones very naturally and is, therefore, optimal to scare away martens.
No penetration of dust at a low pressure of 20mbar in the case. Protected against hose water from any direction against the case (corresponds to 12.5 ltr./minute – garden hose) (test period: 5 minutes)
Chases away the marten through high-voltage plates (movable) charged electrically to approx. 200 - 300 V/DC through electric shock in the motor compartment of the vehicle (only weak current pulses that merely chase the marten away but do not kill it) and through strong, aggressively pulsating ultrasonic sounds. Extremely low current consumption (< 0.005 A), switches off automatically at a battery voltage of < 11.5 V/DC (does not discharge the battery if vehicles are being parked for quite some time). The basic device with the ultrasound radiation is splash-proof according to IP 65* and may be mounted directly at the vestibule opening of the marten in the car. Built-in brightly blinking LED.

Available accessories:
M038N - DC-Converter
Z115 - "Ground"-Mat for electroshock devices
Z176 - Extension-set 2 highvoltage plates for M176
