Byron Door Bell - Help Required

rando

We have a Byron Victoria Door Bell :
http://www.chbyron.eu/admin/pdfs/6257---%20manual.pdf
When connected to the transformer you can hear a constant buzzing coming from the bell unit. So i tried connecting it to a battery but this just drained the battery after several hours.(The door bell push unit does not have a back light to it).
Any ideas please as to the problem.

you have at least 2 problems. On the plus side, your problems sound really simple.

problem (3) back light will drain the battery - unless it is a special led circuit, which will drain the battery slower. You need a transformer for a real light otherwise that bell will need batteries changing on a daily/monthly basis. Also if the resistance of the bulb is high enough you may get away with having the bulb in there, but there will always be current flowing through the bell

You can use 3 core able for a bell light , switch and a common ground, or two core cable and diodes using the positive cycle to power the light and negative one to power the bell, but think you will have to double the voltage

Problem2. that bell should RING. batteries are either inserted wrong way ans there is not enough power to ring, only vibrate causing buzzing or another fault like the contact is too rar an there is not enough energy to vibrate (these bells do vibrate, rather than a turning motor on a cam? The vibrator screw may be turned to close and that may also stop it vibrating. Also if the voltage is a series connection, the wire going from the bell to the switch and back again may be to thin and you may not have enough current?

Problem(1) your switch circuitry or relay is wired wrong/faulty, as it should only ring/vibrate when the button is pressed, something is up with your button, or you have a short.

I would take it off the wall, plug in the batteries (new ones?) and get a short piece of mains cable as twin flex. wire it up as normal but for a switch just short the ends out like the switch does. Once the ends are shorted and the circuit is made you can always fiddle at the solenoid end.

You have wired that light in parallel with the bell and not in series as that could produce the same effect as what you have now, but when the button is pressed it should ring.

The bell does ring when wired to the transformer its just that there is a constance background buzzing noise coming from the unit. Also when I install a new battery and try it this way rather than off the transformer the bell does ring but the battery does not even last a day !
I have tried follwoing the connections as per the instructions for wiring to the transformer but as they are not in colour I am guessing as to which to wires need to go in the slot 4 (one from bell push and one from transformer).
I suspect it is a fault in the wiring from the bell push but this will not be easy to replace as its fed down the upvc door frame via the ceiling space in the hall.
May just give it up and buy a wireless bell !!

there is nor real colour of wiring for this. all it is is one wire goes from one end of the battery (transformer) to the bell and then from the other side of the bell through a switch and back to the other end of a battery.

Your first connection from the battery to the bell is probably already made since the batteries are located in the bell. all is left for you to do is short out (either via a switch, bell press, cables or wire jumper) the two remaining contact points.

Leaving the contacts open the bell should not vibrate or ring, and should only ring when shortened.

Have a look here as it is near enough your exact setup. http://www.gcsescience.com/pme6.htm

Check the wiring is correct then remove the door push button and check it is not wet and corroded or have a spider living in there (mine did) as this can cause a small current to flow all the time (causing the buzzing and draining the batteries).
Remove the wires from the push button to see if the buzzing stops, if it does I would get a new push button.
If you use batteries then the wires from the transformer need to be disconnected from the bell so that the batteries are not damaged or drained by the transformer.

As mentioned you could have a short in the bell push or a short on the bell push wiring.

A funny thing is a mains driven bell. It sits there drawing mains power all year through. And costing money, ok just a little, but when things go bad, bad things happen. The transformer that you hear buzzing starts to overheat and catch fire. If you are lucky the inbuilt thermal fuse blows. You then try to buy a new transformer, costing more than the whole bell unit and when you get it back you find it's every so slighly bigger and does not fit. So you get a new door bell complete, install it but it still does not work so you look around and find the mains isolation breaker has tripped. You reset this only for it to trip immediatley. You recheck all the replacement bell wiring you have just installed and find nothing wrong, still the circuit breaker still trips out. You buy a replacement breaker. All beacause you want a mains bell and not batteries, that last several years anyway.....A true story as it happened to a mate.

Well having read that I think I will just buy a £10 Wireless Bell from B&Q .

Well i gave up trying to resolve the problem with the Byron Bell and had no success at all trying to contact them. I ended up buying a £10 wireless door bell from b&q.
