Do you have trouble hearing your current doorbell throughout your home? The Extend-A-Chime is a terrific product and in a nutshell, it will extend the listening range or your current wired doorbell by allowing you to add wireless battery operated or plug-in door chime receivers in other areas of your home.

It works by wiring in a small wireless transmitter into your current wired doorbell transformer and then plugging in your new add-on Carlon brand wireless door chime receivers. Although the product is compatible with a wide range of wired door chime models, there are some we have found not to be compatible.

1800doorbell has verified that the following WIRED doorbell models are NOT compatible with our Carlon Brand Door Bells. These units are the "Musical Record-A-Tune" which requires a micro processor within the circuit board which makes the "Extend-A-Units" continuously ring. Therefore, they are not compatible with RC3200 and the RC3500 Extend-A-Chime products.

Carlon Wired Door Chimes:

  • DH840E/SS840E
  • DH852E/DH853E
  • SS852E/SS853E
  • DH845E/SS845E
  • SS846E/SS856E

We also found that some of the Broan Product Line of WIRED doorbells are NOT compatible either.

Broan Wired Door Chimes:

  • RC305
  • RC306

It's much easier to use a wired doorbell push button with a wireless receiver using the LRA-EX1000 Extend a Chime.

However, with a little ingenuity, we can add a wireless push button to your current wired chime. To do this, we are going to use the ERA-UTDCR Long Range Wireless Door Chime Kit by Safeguard Supply.

The wireless push button we will use is the ERA-UTX. When triggered, this push button will cause the ERA-DCRX wireless receiver to chime. On the back of the ERA-DCRX is a c-form relay. We will use the section labeled "Relay"

Assuming you want to put this wireless push button on the front door, open the cover of your wired doorbell and remove the wire for the "front" door.
