Car marten repeller with 12 volts - M100 new version

• Installation in the vehicle engine compartment
• Ultrasonic marten deterrent for use in vehicles, houses and attics
• Generates extremely loud, pulsating ultrasonic tones with a special dome speaker

Generates aggressive ultrasonic tones that are inaudible to humans, but which martens find extremely annoying and therefore avoid if possible.

Technical specifications

• Operating voltage: 11 - 15 V/DC
• Switch-on function: Soft start, so that the on-board computer is not disturbed

• Ultrasonic frequency: approx. 23 kHz
• Beam angle: with a special dome speaker approx. 140°
• Sound pressure level: max. approx. 100 dB ± 20%.
• Sound: loud, pulsating
• Speaker: ceramic piezo ultrasonic speaker with aluminum dome membrane
• Optical deterrent: pulsating LED
• Temperature range: approx. -25 to +80 degrees C
• Electronics: waterproof encapsulated
• Fuse in fuse holder: F500mA
• Voltage spikes: protected against voltage spikes in the vehicle electrical system up to 40 V (<20 ms)
• CAN data bus: suitable for vehicles with CAN data bus

Why doesn't the device have a frequency change?
Martens and other small predators emit short, violent warning cries, No siren sounds! Our marten deterrent imitates these sine-like tones very realistically and is therefore the optimal marten deterrent!

Dimensions: approx. 72 x 50 x 28 mm (without mounting tabs)

The ADAC stated the following in a report on marten deterrent measures: "Ultrasonic devices should have a sound pressure level of over 100 dB(C) to prevent habituation (ADAC test result)."

Note:
If the LED flashes or lights up, the marten deterrent is working! The device's current consumption is 20 mA, so it takes a while for a car battery to discharge. Nevertheless, you should recharge the battery from time to time or simply drive the vehicle in between.
