I have a wired doorbell, but want to keep my existing wired push button. Can I link my wired push button to a Honeywell wireless doorbell?

Yes, Honeywell Home offer a Wired to Wireless Converter (Part number: DCP917x) that connects to an existing wired push button which will allow it to work with Honeywell Home wireless doorbells via Honeywell Home ActivLink® or Friedland 868Mhz .
