Two Door Chimes

Not really. Just install a larger transformer and ake sure the voltage requirements are the same for both chimes.

While you're at it, an extra button upstairs connected to the "1 ding only" (rear or side door terminal) of the downstairs chime makes for a good in-house signal system, it could mean "I'm not calling you again, dinner is ready" or "I already answered the door someone is on the way down to see you."

Good idea! (that use of the single ringer!) Another word of caution - I wasn't thinking when I bought a simple old-fashioned buzzer kind of doorbell for my 'remote'. Problem is, it only rings as long as the person holds the button. Most DB's are the "ding dong" with the "ding" happening when the circuit is closed (i.e. button pushed) and the "dong" coming when the circuit opens (button released). Most people don't hold the button for long, so I'm lucky if I get a noticeable Buzz out of my buzzer at all.

blah... suckful... Solutions i can think of: replace the unit small sign "Hold doorbell switch in for 1 second" Have doorbell switch trigger a small timer circuit that will close contacts for 1-2 seconds. good luck!

I have two in my house too, and they work great. I have a three-story house and when I'm in the top floor office I can't hear the wired doorbell at all. On the second floor, if the TV is on, hearing the wired bell is problematic. But by attaching the Dimango transmitter to the existing wired chime and plugging in the two remote units, I can hear anyone at the door from anywhere in the house. My only complaint is that the company has twice changed the design on the model I was using, and when a remote burned out I had to replace the entire system, not just the remote.
