The Buzz LO can be connected wirelessly to this wireless gong. The Bell ME runs on batteries and can therefore be placed anywhere in the house. This means you can also hear the doorbell from the garden or loft. Decide for yourself if you will continue to use your existing gong (chime box). Put a Bell ME in every room. You can connect an unlimited number of Bell ME gongs to the Buzz LO. Hear your doorbell ringing anytime, anywhere. Use the Buzz LO in combination with your existing chime box (gong). Place a Bell ME in the garden, loft or practice room. The Bell ME only works with the Buzz LO and can therefore NOT be connected to other doorbells.
