Default Electronic insect repeller - problems for DCC?

Hi
We have a plug-in electronic insect repeller which operates by sending a high frequency sound wave through our house ring main.

Is anyone aware that this may have an adverse effect on a DCC signal.

Many thanks

Jonathan.

I very much doubt it. As many DCC systems use a DC input derived from aisolated and regulated power supply.
Even if a low voltage AC is used as the input it will be rectified before being used

Are you sure you have it right? A sound wave through the ring main, I do not think so.

You can connect broadband and wireless boosters through the ring main so why not a sound

Electronic insect/pest repellents are usually sub £10 devices that emit ultrasonic sounds through the air of the room they are sited in. I can see how rats and mice can be repelled and have to take the manufacturers word that they work for insects too. They simply use the socket as a power supply and I cannot see how the ultrasonics would have any effect on the electricity supply that would affect any other devices using the same circuit.

Because sound is not an electromagnetic frequency

No need to be insulting. That sort of advice is not wanted on here.


Thank you to the person who explained why sound canít be transmitted through a ring main. I only mentioned it because I know the internet wireless boosters have to be plugged into the same ring main circuit to work. I tried them once but we have a front and back ring main in our house which is why it didnít work. One was plugged into a front upstairs socket and the other a back downstairs socket. Doh!
