Probably the best wirefree portable doorbell on the market. Fantastic German quality starting with a robust 500m push button which is IP44 rated. The chime units are portable or wall mounted and have a series of changeable motifs to decorate the front of the unit. You can even use a photograph of your own choice which would sit nicely behind the glass effect panel. A choice of 17 polyphonic chime sounds is standard on this unit at a sound level of 83dB @ 1 metre. Not troubled by any interference of other wirefree products as it operates at the less crowded frequency of 868mhgz.

This can be powered by batteries (supplied) or via a 1 amp transformer.
