 Marten repeller for cars - description and installation


This marten repeller unit produces intensively pulsating ultrasonic sound – which is unbearable for martens and similar rodents – therefore it is able to scare away these animals. The set includes 4 small ultrasonic loudspeakers to archieve the best radiation of the ultrasound. The frequency is adjustable, the operating status is indicated by a LED.

Usage: This marten repeller is able to scare away martens from the engine compartments of cars and lorries, just place the speakers where the animals usually gnaw the cables and other plastic parts! Or place it in pantries, cellar or attic in such a way, that speakers can spread the ultrasound for the possible biggest area.

Technical datas:

Operating voltage: 12-15V
 
Current consumption: at 12V < 0,05A
 
Loudspeaker output: only for piezo speakers
 
Audio frequency: adjustable approx. 10-40kHz (+20%)
 
Size of piezo speakers: approx. diameter 30mm x 13mm
 
Size of central unit: approx. 73 x 44 x 28 mm
 
 

Mounting instruction and operation:

The ultrasonic marten repeller unit has to be connected according to the enclosed mounting diagram. (The device requires a fuse, approx. 0,2A. The fuse is not included!)

It can be operated with voltages from 12-15V direct current voltage (car or lorry battery). It is possible to operate the module with a commercial plug-in power supply =12V (current supply at 12V =< 50mA).

1-4 piezo loudspeakers can be connected. The cables leading to the loudspeakers could be up to 50 meters. (The cables are not included!) Considering that ultrasonic sounds show a direct radiation, it is necessary to mount the enclosed speakers to different places (in order to avoid sound „shadows”). The loudspeakers and the central unit should be mounted weatherproof (never expose them to direct humidity). When starting operation of the unit the integrated light emitting diode flashes. With the aid of a small screwdriver the frequency can be adjusted. If the adjustment control is in position 1, there will be heard a high sound. Adjusting the control towards the right side, the sound become even higher and, at least, unhearable (ultrasound).

In the following we would like to state experimantal values indicating which frequencies may be used with different animals in order to archieve best results:

Birds: approx. 10 kHz, position 1-2

Rodents: approx. 24-32 kHz, position 8-9

Insects: approx. 27-35 kHz, position 9-10

Martens: positions 3-4-5-6-7

Note! In most of the cars the binder „15” is returned automatically from positive to earth when switching off the motor. If this is the case with your car, then do not connect the negative pole wire of the marten repeller to earth, but to binder „15”. So the marten repeller will be switched on automatically, when parking the car.

Advice: With this module it is solely possible to connect piezo loudspeakers, never connect dynamic treble loudspeakers!

Ultrasonic sounds signify for animals solely a considerable molestation, but don’t harm them in any way physically. The fear and warning cry of animals is made within the ultrasonic range and have therefore a repelling effect. However there are animals which get accustomed to these sounds (above all during the periods of winter where the living conditions in open country are especially dangerous to life). Therefore it may occur, that despite of the ultrasonic sounds wild animals don’t feel disturbed. In such cases turn the adjustment control to position 3 or 4.

Attention! If the marten was already in your car and has placed its „scent marks”, washing of the motor is absolutely necessary. Also the road surface under the car should be cleaned with cleaning agents in order to remove scent marks.

Safety instructions:

Please read carefully these safety instructions before connecting the marten repeller module!

KEMO modules are manufactured according to DIN EN 60065 and comply with the safety requirements with regard to manufacture. All safety elements required for the final assembly are listed in the mounting instructions and must not be omitted for safety regulations. The assembly and starting may only be carried out by authorised persons who can also be held responsible for possible damage.

The mounting instructions supplied by the manufacturer for completion of the appliances are to be observed. All safety facilities are to be installed for permanent operation and must not be ignored for personal safety. The same applies to the operating instructions mentioned in the manufacturer’s instructions.

This device is not intended for persons under 14 years (it has no CE approval as a children’s toy).

Do not expose the module to extreme temperature (more than 50 °C) and humidity. The regulations for prevention of accidents for electrical installations and operating material of the industrial employer’s liability insurance association are to be observed in industrial facilities.

In schools, training centers and „do-it-yourself” workshops, the operation of these modules is to be supervised reliably by trainned personnel.

For all kits and modules which come into contact with a voltage higher than 25V, the VDE-safety instructions must be observed! The installation and initial operation may only be done by an expert!

The most important safety instructions are: protection against accidental contact for all metallic parts, which can carry more than 25V current! The manufacturer and the distributor refuse to accept responsibility for accidents and injuries caused by this! Strain reliefs at all cables! In case of defect, components or the module can burst! Therefore the module resp. The printed circuit board have to installed in such a way that in this case as well as in case of fire no damage occurs (installation into earthed metallic cupboards or earthed metallic casings and superposing of safety fuses).

Dangerous situations may occur during starting when making a mistake (e.g. in case of short circuits, cables may glow or catch fire, if a car battery is used as a power source without adding a safety device).

If the module is operated with low voltage (<25V), this voltage must only be drawn from a battery, an accumulator or from a stabilized power supply tested for safety. Please do not use any power supplies with unstabilized output voltage as these may supply a much higher output voltage in case of low current load and thus the connected module or device may be destroyed. Example: when running at no-load at an adjusted output voltage of 12V, a power supply without stabilization may have a real output voltage of  >18V and thus may destroy the connected module/device.

When operating the unit with batteries or lithium batteries, respectively, please note the following: danger of explosion of batteries in case of improper exchange of batteries (e.g. in case of improper polarization). Flat batteries must be disposed of according to the manufacturer’s instructions.

If the module or device does not work properly, accidents happened (liquid ran into the device, device felt down etc.), or if it causes strange noises or smells, switch it off immediately (interrupt the current supply such as e.g. pull out the mains plug, switch off or the like). Ask an expert for examination.

Warning: certain ultrasonic frequencies may cause headache to sensitive persons. Please consider this during installation.

The manufacturer and the distributor refuse to accept responsibility in case of any material damage or personal injuries caused by non-compliance with the operating instructions and these safety instructions.

Disposal: If the marten repeller shall be disposed of, it must not thrown into the household waste. It must be disposed of at the collecting points intended for disposal of television sets, computers etc. (please ask your local authority or municipal authority for these collecting points for electronic waste).
