K&K M2700 marten repeller - 360° ultrasound, 22 kHz, 110 dB, waterproof, 12 V, for car and motorhome engine bays
- K&K M2700 ultrasonic marten repeller for the engine bay. The dome sends pulsating ultrasound of approx. 22 kHz and 110 dB over 360°. Waterproof, so it can be fitted low down. 12 V, below 2 mA, E1.
The K&K M2700 is an ultrasonic marten repeller for the engine bay of cars and motorhomes with a 12 V system. Instead of driving the marten out of the engine bay, it builds an invisible ultrasonic barrier where the animal gets into the vehicle. The electronics are sealed and the speaker is fully enclosed, so the device can be fitted low down, even in splash water areas. It even withstands engine washing.

360° ultrasound
- the whole dome vibrates and radiates in all directions, with no acoustic shadow
- pulsating sine ultrasound of approx. 22 kHz, varying in frequency and cycle to prevent habituation
- sound pressure approx. 110 dB
- inaudible to humans
- a flashing LED deters and shows that the device is working

Design
- waterproof electronics and enclosed speaker (IP 67 according to the manufacturer)
- acid-proof, self-extinguishing plastic housing
- E1 approval of the German Federal Motor Transport Authority
- suitable for CAN bus vehicles, also electric and plug-in hybrid vehicles
- dimensions approx. 85 x 53 x 42 mm

Installation and connection
- installation by a specialist workshop is recommended
- fit it where it cannot overheat, not on the exhaust manifold, with free space in front of the dome
- positive lead with fuse holder to the positive terminal of the 12 V battery
- earth lead to the negative terminal or vehicle earth (continuous operation) or to terminal 15 - then the device switches off while the engine is running
- remove the fuse when jump starting, welding or fast charging
- 24 V systems only via a voltage converter

Questions and answers
Can it be fitted low in the engine bay?
Yes. The electronics are waterproof and the speaker is enclosed, so the manufacturer intends it to be fitted low down at the marten entry points, even in splash water areas.
Will it drain the battery?
The average current draw is below 2 mA.
Does it work in electric cars or with CAN bus?
Yes, the manufacturer also recommends it for electric and plug-in hybrid vehicles with CAN bus. Observe the vehicle-specific safety rules when working on such vehicles.
Can I hear it in the car?
No. Ultrasound of approx. 22 kHz is inaudible to humans. The flashing LED shows that the device is working.
