How do marten- repellent products work? What are the benefits of K&K products?
Conventional contact plates can only trigger high voltage through the marten’s paws and snout. The fur, on the other hand, insulates and protects the nocturnal predator. The all-new brush strands now run right through the fur to the body of the animal and thus increase the attack surface many times over. Furthermore, the two plus and minus brush strands are interlocked. This allows the brushes to be installed regardless of the surroundings. Newer vehicles, made with more plastic parts, already have enough grounding points, but with the multi-contact high-voltage brushes the installation can now be carried out from a purely strategic point of view in the areas most susceptible to being bitten.
The main advantage is that it allows for more effective defence It also allows the device to be installed low down in the vehicle, in areas that may become very wet. And another thing; ultrasound spreads like light. This means it is barely noticeable behind barriers and acoustic shadows are created.
A low-mounted sound source can radiate sound without any obstructions, creating a soundproof rug. The marten is “caught” even before it enters the engine compartment, expanding the defence radius many times over.
Waterproof marten-repellent devices are also more robust, and can therefore withstand engine washing too.
For us, water resistance is not just about encapsulating the electronics – which is a feature of all our devices. We also make sure that all other components, such as the multi-pin plug and/or safety switch, are waterproof too. The housing and speaker membranes are also sealed. The ultrasound tones are not emitted through openings, but through the closed dome itself. This completely avoids any penetration of water and moisture, and even any mechanical damage are completely. Even our waterproof high-voltage devices are ideally suited for low installation in areas affected by spray.
The marten-repellent device does not have to start operating until the car is being parked. To make sure it starts up when needed, we have developed automatic activation, while at the same time avoiding the need for a connection to vehicle terminal 15 (ignition). This saves a great deal of installation time.
The automatic activation allows the marten- repellent device to recognise which ‘state’ the vehicle is in based on the battery current. When the engine starts, the device switches off, so it only works when the engine is switched off.
K&K devices start up slowly using an intelligent soft-start circuit and operate at very low level of power consumption. Even the latest, highly-sensitive on-board computers do not identify our devices as power consumers. Unlike devices with a ‘hard’ startup system and current pulses up to 25mA, K&K will not generate error messages. Always at the cutting edge of technology. Compatible with the latest generation of engines.
The built-in battery monitor shuts down the marten defence system when it reaches a certain specified operating voltage and turns it on again when the on-board voltage returns to normal. This protects weak batteries against discharge.
In the event of bridging (e.g. a damp leaf on a contact plate), our device has an automatic current drain, ensuring the device will not affect the on-board electronics or drain the batteries unnecessarily.
