Kemo M100N Ultrasonic Marten Scarecrow for Use in Cars, Houses and Attics

Martens and other small predators emit short, violent warning screams, no siren sounds! Our marten scarecrow imitates these sinusoidal tones very lifelike and is therefore the optimal marten deterrent Creates inaudible aggressive ultrasonic sounds that are perceived by martens as extremely annoying Sound: loud pulsating speaker -- ceramic piezo ultrasonic speaker with aluminium dome membrane. Optical deterrent --- Pulsating LED --- Temperature range approx. -25 to +80 °C Electronics: waterproof moulded fuse in fuse holder F500 mA. Dimensions approx. 72 x 50 x 28 mm (without mounting straps). Voltage spikes. Protected against voltage spikes in the on-board network up to 40 V ( < 20 ms) Features: strong hemisphere dome speaker, 2 times effective ultrasound + pulsating light. Operating voltage 11 - 15 V DC (car battery) switch-on function soft start so that the on-board computer is not disturbed Please install the marten scarecrow in a place in the car that cannot get so hot. So not so far up in the car, not next to the exhaust manifold or similar hot positions. The ideal places are usually on the rear wall to the driver's cab or right next to the radiator fan. High heat > 80 °C ensures a low service life of the marten scare This marten scarer can also be operated in a 24 V/DC truck. But you must then switch our module M038N upstream (voltage converter from 24 V/DC to 12 V/DC). The module M038N is not included
