Subject: How can I use 15vAC to trigger a relay?

I live in an old, old apt. bulding in brooklyn. The current doorbell system uses an old push-button system that sends approx. 10-12vAC to two wires in my kitchen presumably via step-down transformer(originally to trigger a really annoying bell-strike buzzer). One of them is white, the other red. My intention is to somehow convert the AC into DC using a diode, and then install a relay to close a circuit on a more sophisticated doorbell-entry system I am trying to install.

I know this is somehow possible, but my electronics knowledge is strictly rudamentary, with most of my expeience stemming from 12v automotive-electronics.

Can someone please help? I have this thing about blowing myself up.

Thank you.
