The RC4121 is a wireless transmitter (doorbell button) by Carlon with a range of up to 250ft.  This is the button used in the long-range wireless door chime kit by Carlon, the RC4120.

This button works with all Carlon (Dimango/Thomas & Betts) door chime products.  The standard button from Carlon has a wireless range of up to 150 ft. from transmitter to receiver, and in some cases, may not offer the extended range you need.  In that case, as long as the distance is less than 250 ft., we would recommend this button.  Please note: environmental factors will diminish the operating range of any wireless product.  Each wall the signal has to pass through will degrade the signal.

Here’s a scenario:  You could use the RC3250 plugin door chime kit which comes with one push button transmitter and one receiver.  Then you decide you want to put a push button at your side door, but the distance to the receiver is 160 ft.  You purchase the RC4121 and use it with your existing system.

  • Long Range Wireless Button
  • Battery operated: 2 x 3V lithium batteries included
  • Up to 250′ operating range from transmitter to receiver.  Building materials will reduce the range
  • 32 selectable codes block interference from outside signals or other wireless devices
  • Set sound on front of a button so you can make button A play a selected tune, while button B plays a different tune.  This allows you to distinguish which door the visitor has triggered
  • Compatible with all Thomas & Betts, Carlon wireless chime systems
  • Manufactured by Thomas & Betts, using the Carlon/Dimango brand name
  • One year manufacturer’s warranty
