Jacob Jensen doorbells are beautifully designed, with a wonderful rich clear sound coming from a large internal speaker, and are supplied with robust bell pushes. The 5 melodies are unusual, including a “knocking at a door” and “Oriental-Inspired tune”. We supply the standard kits plus twin packs, front door / back door kits plus additional chime units and bell pushes to extend the system. The packaging is very well presented, and these doorbells make wonderful presents. Listen to the sound samples at the link [ Jacob Jensen Sounds ]
