Bell Cable

Bell wire is a light, twin-conductor cable designed for extra-low-voltage circuits such as wired doorbells, bell pushes and chimes. We stock white bell wire in a handy 100m coil, which is easy to clip along skirtings, architraves and door frames for a neat finish.

It is also handy for simple low-voltage signalling and small speaker runs. Trade account holders get trade pricing, and in-stock orders placed by 5pm on a weekday are delivered the next working day across NI and ROI.

Choosing and installing bell wire

Bell wire is one of the simplest cables on any job, but it is only suitable for the right kind of circuit. It is built for the low voltages produced by a doorbell transformer or batteries, not for mains power.

What bell wire is used for

Connecting a bell push to a wired chime or bell
Wiring a chime to a bell transformer's low-voltage output
Simple low-voltage signalling between rooms
Short, light-duty speaker or sensor runs where nothing more specialised is needed

Things to check before you install

Never connect bell wire to mains voltage. If a chime is powered from a transformer, the mains side of that transformer must be wired in proper fixed-wiring cable and protected according to current wiring regulations; only the low-voltage output should be run in bell wire. Always follow the chime manufacturer's instructions for voltage and polarity.

Bell wire has thin conductors, so keep runs reasonably short to avoid a weak chime. Keep it separate from mains cables where practical, and protect it where it passes through holes in timber or masonry. For longer or more complex runs, such as intruder alarm or access control systems, multicore alarm cable is a better choice.

A tidy finish

Because bell wire is often surface-run in hallways, plan the route along door frames and skirting so it stays discreet. Fix it with small cable clips rather than staples that could pierce the insulation. If you are replacing the chime itself, browse our door bells range at the same time.

FAQ's Ask Your Own Question

Can bell wire be used for mains voltage?: No. Bell wire is made for extra-low-voltage circuits only, such as the output of a doorbell transformer or a battery-powered chime. Mains circuits must be wired in a cable rated for the voltage and current involved, installed in line with current wiring regulations. If in doubt, check the cable's rating and the device manufacturer's instructions.
How long can a bell wire run be?: Bell wire works best over relatively short runs, because its thin conductors cause voltage drop over distance and the chime may sound weak. For a typical house, front and back door runs are rarely a problem. For long runs, check the chime manufacturer's guidance or consider a larger conductor cable.
Does polarity matter when connecting bell wire?: For a basic mechanical chime on an AC transformer, polarity usually does not matter. Some electronic chimes, illuminated bell pushes and battery-powered units are polarity sensitive, so follow the manufacturer's wiring diagram and keep a consistent conductor for each terminal throughout the run.
How do I connect bell wire to a doorbell transformer?: Connect the bell wire only to the transformer's low-voltage output terminals, then run it to the chime and bell push in series as the chime instructions show. The transformer's mains input must be wired by a competent person, isolated first and protected appropriately. Never work on the mains side while it is live.
Can bell wire be run outside?: Standard white bell wire is intended for indoor use. A short length to an external bell push is common, but keep it as protected as possible, seal the entry hole and avoid long exposed runs in sunlight. For longer outdoor runs, choose a cable designed for external use.
How quickly can I get bell wire delivered?: If the 100m coil is in stock and you order by 5pm Monday to Friday, it will be delivered the next working day across Northern Ireland and the Republic of Ireland. Orders over £30 / €35 ex VAT ship free, or you can collect from our Cookstown trade counter.
