GreenBlue Wireless Doorbell for the Front Door, 38 Melodies (Black) Battery-powered both components, 4 volume settings, LED display, range of up to 200 m

38 MELODIES TO CHOOSE FROM – With the GreenBlue GB237, you can choose from 38 melodies and signal tones, allowing you to customise the sound to suit your taste. It is ideal as a doorbell for your house, flat, office, shop or holiday home. FOUR VOLUME SETTINGS – The receiver features four-level volume control, allowing you to easily adjust the signal to suit the room and surroundings. You can select a quieter setting for smaller rooms or a louder signal for a larger house, garage or workshop. RANGE OF UP TO 200 M – The doorbell allows signal transmission over a distance of up to 200 m in open space. This means you can position the receiver far away from the front door, for example on the upper floor or in another room. Please note that walls, ceilings and metal obstacles may reduce the actual range. WIRELESS INSTALLATION – The transmitter and receiver communicate wirelessly, so no cables are required between the door and the signal reception point. The button can be attached using the double-sided adhesive tape provided, and the receiver can be placed or mounted on any surface. TRANSMITTER WITH PROTECTION CLASS IP44 – The doorbell button is protected against the ingress of solid objects with a diameter of 1 mm or more, as well as against splashing water. It can therefore be installed at the entrance or on a gate in a location that is sheltered from direct exposure to the elements. The receiver complies with protection class IP20 and should be used indoors. BATTERY OPERATION – Both the transmitter and the receiver are battery-powered, so the receiver does not need to be connected to a mains socket. A 12 V 23 A battery for the transmitter is included, whilst the receiver requires three 1.5 V AA batteries, which must be purchased separately. LED IN THE TRANSMITTER – A blue LED lights up when the button is pressed, providing additional visual confirmation that the transmitter is active. This is a handy feature that allows you to see how the transmitter is responding when using the doorbell. FOR THE HOME AND OTHER SPACES – Thanks to its universal colour and compact dimensions, the set fits into a variety of spaces. You can use it in your flat, house, office, shop, garage or holiday home – wherever a wireless visitor alert system is useful.
