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 the hole is drilled, place the push button over it so the wire hole in the rear of the push button is over the hole you just drilled. Mark each fixing hole for the push button on the door frame using a pencil or 2mm drill bit if you can’t get a pencil through each hole.

As our unit has the transformer built in all that was needed was to run a live feed from the existing circuit down and connect it to the transformer in the chime unit. With the circuit isolated a junction box was installed into the existing lighting circuit the feed was being taken from and then the 1mm twin and earth cable that was previously fed up from the chime unit was connected up.In the mean time various visitors, couriers etc. come and go, ringing your door bell that at this time doesn’t work so they presume no one is in, when in fact you very well could be. In most cases chime units are installed either above a doorway or up near the ceiling somewhere so that when the connecting wire is dropped down it’s then not visible as it can run straight into the unit.

Once it’s plugged in, your Nest Doorbell should turn on, and its light ring should turn blue. Troubleshooting The push button cable was then run up through the hole as the electrical supply cable and then over and down through another hole near to where it will exit through the door frame. In this case an existing ceiling hole close to where the push button was to be installed was used. There are 3 main parts to a standard wired doorbell system; the chime unit, the transformer and the push button unit.

Once marked drill a small pilot hole and then screw the push button in place. Not fully as yet as we will need to remove it to wire it up. Step 2 – Find Location and Fix Chime Unit 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.

As mentioned above, where the push button units are hard wired to the chime as their power source, this needs to be done via a transformer to reduce the power to the push button to a safe amount so that it can be used in and around the home or externally. In the majority of cases this will be around 12V but sometimes much less (around 2V). Discover the new strength. The BG Fortress Circuit Protection range has undergone its most extensive upgrade yet.
