I would like to hook up a door bell generator to the paging input of my whole house audio system. The only thing I really need is something that will generate a "ding-dong" when a contact is closed. I see some kits on the web but I am wondering if anyone has actually done this and what they have used. I am looking to buy this in the USA. I could probably wire up a circuit with an IC but I don't know who sells this stuff retail, like in a Radio Shack or whatever. Please advise. Thanks.
