The Honeywell DC313NHGP2 is a complete doorbell set. The set consists of a doorbell button, wireless receiver, and a power socket receiver. This way you'll hear your doorbell anywhere in your house, even in the garden, for example. You can take the wireless receiver anywhere you go in your home. All components will be ready for use the moment you take the doorbell out of the packaging. You'll only have to think about suitable placement. The receivers and doorbell button have a maximum range of 150 meters and come with 6 melodies, with a maximum noise level of 84 decibels. Thanks to the integrated LED lighting, you'll not only hear the doorbell, but it'll also be visible. This is especially convenient when you've got the sound on your TV set too loud, for example.
