The DC311N doesn’t have all the smart features of the higher-end DC917, but if you’re looking for a reliable push-button bell with battery chime, you won’t get much better. With a 150m range, you can carry the chime unit around the house or even outside. The connection seems to be exceptionally good. It’s loud, so should still be audible if your hearing isn’t so good, and while you only have the option of four different chimes they’re all quite listenable.

When it comes to the wireless units, as you may expect the majority of these are purely wireless and draw their power from batteries as opposed to the mains. As you will need to run the wires for the bell from outside to the inside and to the transformer unit/chime unit, in most cases the best installation location is on the door frame as this is the easiest area to drill through. However if this isn’t possible then you will need to install on your wall and drill through the wall.

Safety tips

When it comes to powering smart door bells this is generally done through either hard wiring to the mains and using a transformer to step down the voltage so its a low voltage supply or wirelessly using batteries. The next job then is to connect up the live feed to the transformer from the existing circuit. Before any work was carried out, the electrician doing the job isolated the circuit we were taking a feed from by turning it off in the consumer unit and then testing that the circuit was indeed fully isolated! Once fully tested from an electrical perspective the final job was to give the push button a push and ensure that the chime unit sprung into life and indeed it did. Depending on the type of doorbell system you are installing will depend on how it’s powered. Some units have a separate external transformer that requires a feed to be taken from an existing circuit via a junction box and some units have their own transformer that is installed within the consumer unit and power taken from there or the transformer is physically built into the chime unit. With separate transformer units, these are very often installed on or around the junction box used to take a power feed. The power feed is taken out of the junction box and then live, neutral and earth are connected into the transformer and the chime and push button units are then wired into the transformer.

In the majority of cases the junction box/transformer setup tends to be an older type setup with the newer models being much more simple to install and therefore utilising a consumer unit transformer or the transformer as part of the chime unit. As mentioned above as we are using a unit with the transform integrated into the chime we don’t need a separate transformer, however in some cases the transformer comes as an individual unit that is either installed next to the junction box or power source or as a unit that installs within a consumer unit on the Din bar along with existing MCB’s and RCD’s. If you are plugging the transformer in, then a 3A fuse in the plug is needed. The cable from the plug to the transformer needs to be able to carry 3amp, so anything 0.75mm² or larger will be fine. eg such as that used for a table lamp. In terms of wired door bells there are also a few different types – those that are hard wired to a mains electric supply to draw their power with the push button mechanism also hardwired to the control or chime unit via a transformer and those that have their control/chime units hard wired to the mains but their push button units are wireless.

Battery life is important for battery-powered models because – trust us – you will keep putting off replacing the batteries for longer than you should.

Another very useful feature is that most smart systems also have a built-in microphone and speaker meaning that 2-way communication with the person standing on your door step is also possible. This is particularly useful if you are away from your property.
