SUMMARY

The discussion centers on troubleshooting a musical doorbell system in a condo built in 1992. The user reports that while the standard ding-dong sound functions correctly, the musical feature, controlled by a DIP switch box with wires labeled FRONT, REAR, and TRANS, does not work despite various wiring attempts. The absence of a transformer, which is likely hidden in the ceiling, complicates the situation, as the user cannot access it for further investigation. The community suggests checking battery connections, although the user confirms that no batteries are involved.

I just purchased a condo built in 1992. The door bell is fine in that I get the ding-dong sound.
However, attached to the door bell is a small box with DIP switch selectable music. This box has wires labeled FRONT, REAR, and TRANS.
The wires were attached to the to the corresponding wire on the bell. I tried various wiring and DIP switch settings but I only get the ding-dong.
Here's pics of the bell and small box. Any idea how this is supposed work?

Thanks

We had one of those, but it was battery powered. Have you checked the battery? ;)

Also, your pictures either were removed or didn't work. Try using the "attach" button, that should work, I think.
 
Thanks for the replies.

There are no batteries involved.

Unfortunately I can't find the transformer. It's not in the circuit breaker box so it's probably buried in the ceiling which I don't have access to.
