Use the Byron BY503 Portable Wireless doorbell kit with black and silver bell push wherever you want at home, so you will always be able to hear the doorbell ringing. You will not have to worry about wiring because the door chime is powered by batteries.

Never miss a visitor
The wireless doorbell kit contains a bell push and a portable door chime. Take the portable door chime anywhere by just using 3x AA batteries, this way you will never have to miss a visitor.

Weatherproof bell push
The weatherproof bell push has an IP44 rating and contains a nameplate to make sure visitors can easily find the correct doorbell. Visitors will know if they rang the doorbell thanks to the bell push that illuminates when used.

Wide range
The bell push and indoor unit have a range up to 125 meters. The range might be reduced by walls and obstacles: - Open space: 100% range - Wooden walls and large obstacles, such as closets and other large furniture: 80 – 95% range - Stone walls and large obstacles: 60 – 80% range - Metal walls and large obstacles: 0 - 20% range

Customize your doorbell
The doorbell kit has 8 different melodies that allow you to choose the melody you like the most. The volume level is easily adjusted, this way you are always sure you can hear the doorbell ringing.

Easy to install
You can mount the bell push by just using 2 screws or double coated tape. Connect the bell push and door chime in just seconds. The doorbell will not interfere with your neighbours' doorbell because it has many self-learning codes that automatically choose an unique frequency. The portable door chime can be mounted to the wall if you prefer to have it on a fixed place.

Expandable kit
You can expand the doorbell set by adding an extra bell push, for example to have a doorbell at both your front and back door. Therefore, you can choose from the following Byron products: BY30, BY33, BY34, BY35, BY37 and BY37Z.

UK orders placed before 10:00am and fulfilled from stock will normally be dispatched within 2 days for delivery on the next working day by Royal Mail 1st Class, but can be up to 5 working days for non stock, or out of stock, items. Some heavier or longer items will be sent by 2nd class mail or by Royal Mail Parcels. Internet placed orders will receive an email, advising despatch has taken place.

If we are out of stock on a particular item, we will delay the whole delivery where we expect the item to come into stock within 7 days. We will e-mail you if this is likely.

We will deliver part orders where the majority of the items on the order are available, and the outstanding items are unlikely to come into stock within 7 days. In this case we will invoice for the whole order including the items out of stock, and advise you of this on the invoice. The balance of the order will be delivered without additional delivery charges.

We use Royal Mail 1st and 2nd Class or Royal Mail Parcels for heavier or longer cartons for UK mainland deliveries. International orders are shipped by Airmail with a maximum weight of 3 kg.

Delivery Charges

UK and European Union

The cost of the UK service is based on weight and size and the costs can be seen at checkout. Orders over 2 kg will carry a increase in shipping costs. UK orders over £100.00 and above are Free

The best way to see the delivery charge is for you to go through the buying process but stop at the Checkout point where you are requested to confirm your purchase. At this stage the delivery charges will have been added to the total cost, including VAT.


We are now able to ship most products to any location in the world. Exceptions, are where the packaging weight is over 3Kg, the maximum for Airmail. Please email us if you are concerned, regarding the weight of your order, or wish to have a special quoted price for delivery of heavier parcels. Although export items outside the EU are exempt from VAT, the normal VAT tax content will be used to cover the increased shipping cost. The price shown for UK orders in £s, will be the price you pay. Orders will be sent by tracked Airmail.

Right to Cancel and Returns for Refund

We offer a no-quibble returns policy. If you decide you do not need the goods, for any reason, they may be returned within 30 days of receipt (at your own expense) for a full refund.

Prior to dispatching goods for return, you must contact us by telephone (tel: 01629 831000) to facilitate the process. The returned package should also contain your name, address and the invoice number. Please put a note in the returned package to indicate whether the item is faulty, or just not required.

Goods returned must be in the original condition in which they were supplied and include all items of the product and its packaging. Where the packaging needs to be destroyed to open, we accept return without the external package, however, when the package is a box, and can easily be opened without damage, then we expect the goods to be returned with the box in a new condition.

Goods returned for refund should be sent at your expense to:

Sabrebond Ltd T/A Doorbell World, Unit 5, Edmund Road Business Centre, 135 Edmund Road, Sheffield, S2 4ED

NB: Until received, the goods remain your property and we recommend suitable packaging and an appropriate level of insurance for their return.

All goods and packaging will be checked carefully and the refund processed as soon as possible. Notification of your refund will be sent by Email or through the post.

Warranty Returns for Replacement or Repair

All products are covered by a minimum 12 month warranty. Some manufacturers offer longer warranty periods. Manufacturer warranties beyond 12 months are supported by manufacturer only, and not by DoorbellWorld. Where a warranty request is required from the manufacturer we will supply copies of the original invoice as a supporting document.

To return any unwanted items please package them back up in the original boxes undamaged and unused. Include your name, order number and reason for return. This way the returns team will know what  to do with the package when it arrives back to us. We suggest you do not despatch goods without first contacting us by telephone (tel: 01629 831000). The reasons for this are:

  • Past experience has shown that apparently faulty goods have sometimes been set up incorrectly, or the instructions have not been as comprehensive as they should be. In these situations the quickest solution to getting the equipment working correctly is for us to give you further advice to avoid incurring unnecessary delivery charges if we are able to resolve the problem.
  • We may require you to return individual components rather than the complete product.
  • We can advise you on the most appropriate method of returning the goods.
  • Defective goods under 30 days old will be returned to us at our expense provided you have discussed with us first on the method of return. We will supply you with a FREEPOST address label.

The returned package should contain your name, address, your invoice number, details of the fault.

In most cases, where the product is found to have a valid fault, the warranty permits complete replacement of the defective item free of charge. However, some manufacturers require that the product is returned to them for repair, or that the repair is carried out by ourselves once the defective components have been supplied by the manufacturer. In these cases the repair under warranty, free of charge, will take longer.

NB: Note that DoorbellWorld cannot be held liable for any consequential costs incurred as a direct result of the faulty goods.

Goods returned for repair or replacement should be sent to:

Sabrebond Ltd T/A Doorbell World, Unit 5, Edmund Road Business Centre, 135 Edmund Road, Sheffield, S2 4ED
