I am looking into adding a doorbell to a Sonos System. I was looking at the RDL FP-CH8, which looks like it will sieze the speaker level, and play a tone when the doorbell is pressed. My question is: Does anyone make one of these modules that will do several pairs of speakers? Like four input, four output?

Here's the link to the RDL piece:

Thanks,

How do you plan on keeping the Sonos line level input in standby mode after a customer uses the system for music? Just a question? I have a ZP120 in my kitchen that stays on the line level input for my DTV DVR which is playing on the TV.

Edit
I didn't look at the piece in question. I have no idea.

I'll bet Fred Harding's favorite supplier carries something from Viking or... that could do the trick.

Longshot,

The RDL piece would connect between the speakers and the ZP120. When the doorbell is pressed, the contact closure in the RDL piece then automatically grabs the speakers and sends a tone through the speakers using its built in amp. The only problem is that the RDL piece can only hook up to one speaker hooked to another in parallel.


Stanley,

The Viking piece looks like it only does 1 speaker, which gets me back to the same issue as the RDL piece.

Even if there was something that could do this stero, instead of mono. Then I could just use multiple doorbell pieces on each zone they wanted to hear the doorbell in....Anything out there?

I guess I could use two of the RDL's or Vikings, but then I think it would be cost prohibited to do in multiple zones.

Thanks,

Mike

** EDIT - That RDL piece doesn't have an amplifier in it, so this all goes out the window. It's a line level output. **

This would be tricky since you don't have any real control... the only thing I can think of is if all 4 ZonePlayers are in the same spot, you could wire each speaker through an Altronix DPDT relay. (1 relay for each pair of speakers).

On the normally closed side you wire speaker + and - from the Sonos. On the normally open side you wire output + and - from the RDL piece. (You would have to jump from one speaker to the next for this part of it). Then you would wire the "control out" of the RDL to the trigger in of each relay.

Doorbell is pressed, 12v triggers relays to switch speakers to be wired to RDL instead of Sonos, then RDL plays chime. Chime ends and 12v is lost so speakers go back to Sonos.

A couple things I'm not sure about:
- I couldn't figure out how the RDL would deal with having eight 8 ohm speakers paralleled into it. **and this is the point where I realized the RDL only has a line level out. It has to be placed in BETWEEN a source and amplifier. You couldn't use this with a ZP120. You would have to use ZP90's and put one in between each zoneplayer and its accompanying amplifier...

Maybe not the most cost-effective solution, but maybe use 4 of these guys:

along with an inexpensive amp dedicated to the RDL door chime module. Wire the "doorbell amp" to the sense side "AMP B" input of the AB 3.2 and the sonos ZP120 to the "AMP A" input. Adjust sensitivity and delay on each AB 3.2.
