When you have a wired doorbell in your home that you just can’t hear in other rooms, or when you current wired doorbell isn’t loud enough, the Carlon RC3500D may be the solution you are seeking.

This is called a doorbell extender or “extend a chime” by Carlon/Dimango.  The product works when the included transmitter is wired into your existing wired doorbell transformer.  When a visitor presses the button outside, the wireless transmitter sends a signal to the receiver that is included in the kit.

Simply wire the small transmitter into your existing doorbell transmitter by following the easy to follow instructions.  Then make sure you have batteries in a receiver/speaker and you have successfully extending your chime.

The solution works great in situations where wiring a new doorbell is out of the question or for the hard of hearing.

  • Receiver runs on 4 C-size alkaline batteries
  • The receiver may be mounted horizontally or vertically
  • Volume control on receiver
  • Plays six different tunes, selected on the transmitter
  • Plug-in model (RC3253) also available
  • 1 year manufacturer’s warranty
  • Water resistant so it may be mounted outdoors

This unit gives you additional flexibility not traditionally offered with other doorbell units.

    Works as advertized. Directions were clear. Took less than 10 minutes to install the wireless transmitter to the current hardwired doorbell.

    Extremely easy to install. Made adding an additional doorbell chime a 10 minute job…

    Solved a problem. I couldn’t hear the doorbell in my bedroom. Now I can. As it states in the directions, you will only get 1 chime selection if you have a lighted doorbell. One chime is much better than not hearing the doorbell at all!

    Thank you, 1800Doorbell!! For years, we have been having problems hearing our doorbell. Our Extend-A-Chime works great with our wired system. The price was right, it was easy to install, and was much louder than we thought it would be. Now, the true test will come when our enthusiastic football group comes over to watch our favorite team play!! Looking forward to no more situations of our guests having to call us on the phone because they’d been standing at the door ringing the doorbell! Also, since the unit is mobile, if we’re outside, we can position it nearer to us if necessary. Thanks again, 1800Doorbell!

    Unit was available, was priced reasonably, was delivered promptly, correct product received undamaged, installed easily, worked as advertised. Would have liked some different sound patterns rather than the songs.

    Is satisfyingly loud. I hung it in the garage, and it is quite audible throughout back yard. No more missed deliveries from FedEx because I was grabbing something from out back…

    Worked great outdoors. Gives you 3 loudness options plus different types of tones to your liking. Would definitely recommend this product.

    I needed a front doorbell ringer that we could hear in a basement den. This item was easy to install and does a good job. If you have the same problem, you can’t go wrong with this solution.

    Very easy to install. Plenty loud. 6 different sounds. Portable. I have mine 75 feet from the main door bell. Works great.

    I agree with the other comments; it works very well and was simple to install. We wanted it for the patio. The outdoor unit is described as “outdoor rated” and “water resistant,” but I think we’ll just bring it outside with us when we sit on the patio (three or four times a week May-September). It would mount on a wall outside via screws if desired; there are slots in the rear. If I were to do that I’d probably also attach a short sheet of flexible rubber or plastic a couple of inches above it, overhanging the front to shed rain. And the unit could easily be popped off the mounting screws when rain is forecast, and during the off-season.

    Re the comments about loudness, there’s a volume control on the back. Mine was set on High when it arrived; I eventually moved it to Low.
