Just curious, why do most wired doorbells need a transformer, with the associated hassle of wiring from a mains source to the tranformer and then to the bell, when they could just as easily use a 9V battery in the sounder unit instead?

I presume there's a good reason, just I'm too much of a numpty to work it out for myself.

I know there are some battery only devices, but they are all horrible and don't meet SWMBO's audio requirements nor visual aesthetic requirements. And wiring something up doesn't meet my requirements. (And wireless ones are either crap, don't work in my house, look ugly or don't make the right sort of ring for SWMBO!).

Probably because most (?) bell pushes have an internal lamp, so draw
current continuously. A battery wouldn't last very long!

You won't get a loud sounder *and* decent battery life from a 9 volt
battery.

Mains bells also give the possibility of an illuminated bell push.

It's really hardly any more work to fit a transformer if using a cabled
system - and it's then forget time for many many years.

Unless the customer buys the parts. eg MTS8

http://www.electrika.com/f/0150-wylex-09/index.html#9

part of DIN RAIL MODULAR DEVICES FOR USE IN + UNITS AND FLEXIBLE UNITS.

And what was the advice from Wylex technical sercices department (the
customer had a NH CU)?

The advice was, "it does not fit the CU, use a seperate enclosure next to
the CU".

We had one of those old Friedland things with the 4.5V battery and it was
plenty loud enough.
Due to old age (the bell) and difficulty in getting batteries, we no use a
wireless thing.
If I could get another 4.5V one I'd use 4 Eneloops in it - almost zero
running cost and should last a couple of years on a charge.

You can still get battery operated wired door bells - TLC sell them.
Usually use D cells these days.

By 9 volt I assume referred to a PP3. A small battery totally unsuited to
this use - unless driving one of those weedy electronic warblers.

As others have said, most bell pushes have illumination which would be
a constant drain on a battery. Plus, batteries go flat without
informing you so you miss people at the door who have been stood there
ringing a defunct doorbell. Much, much better to have a transformer and
mains power.

For many years we've had the Freidland Underdome D792 bell and it does
exactly what it says on the tin. It's small, unobtrusive, but bloody
LOUD!!

I work from home and when our next-door neighbours (we live in a
semi-detached) are out during the day, or away on holiday, I love to
play my music (Led Zeppelin, AC/DC, The Who, Deep Purple etc., etc) at
very loud volume and was always missing deliveries/callers when we had
a namby-pamby 'ding-dong' type thing, but not anymore - this bell can
be heard all over the house, even when listening to Robert Plant and
the boys in full gusto lol

larkim was thinking very hard :

All maybe true in the distant past, but pay a bit extra for a good
quality modern one and none of that is true. If range is an issue, then
get one of the longer range versions.

The only good reason to have a wired system with a transformer, is if
you must have a light on the push. Run on battery they do not last
long. A wired battery one without a light is otherwise fine, but most
installing one these days choose a wireless option.

Show me a nice looking, high quality wireless one with a proper "bell" sounder, and I'll agree with you. I've certainly not found what she needs!

I thought about it, I just didn't expect the wireless bell which I had lined up to work to be so crap that goes off in the night no matter which channel I configure it up to. The recommendation from here was to look at the more pricey wireless bells (which I have done), but they are all f-ugly and make 1980s style faux-bigben noises as far as I've been able to tell (certainly not the nice ring that SWMBO wants). So I'm back to thinking of wired ones, but the potential power source locations in our house are limited in the area where I'd need them.

To be honest, I'm happy enough with a knocker, but I'm domestically disagreed with.

Power to the transformer is almost never an issue, just use a 5-8v 1A wallwart. Power from theree on can be run on enamelled copper wire on the surface or slipped into cracks, and remain invisible.

I run a wired LAN and a Wireless one. I have LAN sockets in many of the
rooms, but wireless side has the major advantage that I can make use of
it anywhere I happen to be range, which is anywhere in the house and
most of the garden.

A decent wireless door bell has the same advantage, in that I can take
the receiver bell unit anywhere with me. I often spend time in the
garage/ workshop remote from the house and if I'm expecting an arrival,
I can take the bell along with me.

I long ago (before the days of wireless phones) wired up telephone
sockets around the entire house and included one in the garage. Only
one of those sockets is now used, for the wireless phone. If I'm
expecting a call, I carry the phone around with me.

Not a matter of sloth, a much more convenient system.

The sounder for my doorbell plugs into a mains socket, which gets
rid of part of the battery problem. However, because it is not
near the front door, and additionally the sound is produced when
the push is released, callers almost always knock as well.

Somebody recently remarked that it wasn't working, and I
demonstrated their error, commenting to them that I thought the

Good argument.

But surely the next step would be to have a door bell that sends an SMS
- and you can then be alerted on your mobile wheresoever you might be.
Ideally with the ability to make a voice call as well and thereby allow
some dialogue if you really are away. Obviously needs to be a limited
device so no-ones sees them as a way of getting a free mobile...

Their error! Good god, if I didn't knock everytime I couldn't hear a
wireless door chime I'd never get a reply. True the battery in the push
last well, but the ones in the receiver (which are almost always battery
powered) are, more often than not, flat[1] which the owner never seems
to realise.

Bloody things. 4 x C-cell Friedlands rule. Batteries last donkey's years.

Soott

[1] And when they're not flat, the receiver will be randomly unable to
receive the signal.

I can just see Harry wandering around with one of those, mains lead

I have two underdome bells, one in the downstairs hall, one at the top of
the house. Can be heard everywhere - even when listening to the radio or
whatever, and can also be heard outside the front door. The illuminated
bell push may help too - although you still sometimes get numpties who
knock on the door without trying the bell. If you ask them why, the usual
reply is doorbells often don't work. The plague of cheap wireless types.

There is only one advantage of a wireless type. Cheap and cheap/easy to

Words would fail me if that was simply because the mansion was too
large. But out garage is non-contiguous with our house and garden. If I
am there, and partner goes out, I would like something to be able to
hear someone at front door. So a wireless bell would make sense. Don't
want to leave it in the garage. So portable makes 100% sense.

And when my house is large enough, I'll make sure one of the domestic

Presumably you ran power to the garage at some time? So adding a bell
cable and say telephone wouldn't have been much more trouble?

Or, of course, use a wireless link to the garage just for a doorbell.

But perhaps you are a perfect person who never leaves anything lying

End users would get pretty fed up with a system that failed reguarly and didn't even warn them. You also can't get much power from a PP3, you can from a 6v lantern battery, a much better match to most sounders.

and then to the bell, when they could just as easily use a 9V battery
in the sounder unit instead?

I presume there's a good reason, just I'm too much of a numpty to
work it out for myself.

So you can power an illuminated bell push...

I know there are some battery only devices, but they are all horrible
and don't meet SWMBO's audio requirements nor visual aesthetic
requirements. And wiring something up doesn't meet my requirements.
(And wireless ones are either crap, don't work in my house, look ugly
or don't make the right sort of ring for SWMBO!).

How about the mains wireless devices - the sounder plugs into a socket,
and you can invite TMH round the screw the push to the front door!

Wonder how long before they get smashed by the hoover?

Well mine in a socket above dado rail height... so not much danger of
that ;-)

This is slightly off-topic, but something I would consider particularly
if doing serious redecorating would be to install an old fashoned
mechanical bell operated by cable. That if done right and depending on
the property could be a quality enhancement and totally green as it were.

I don't think there is any problem with using DC for a bell. I had one for
years that ran off four D cells, but the thing is that most mechanical ones,
if you like the real chime type employ solonoids which simply goone way
when you hit the bell push and bounce back the other when you let go again
and the idiots that lean on the bell push seem to be multiplying and started
to wear out the batteries. I guess modern bells could hav ehe solonoids
operated by a circuit instead to stop this sort of thing from happening. In
the case above though the transformer and its rectified output put paid to
leaking batteries for ever, well untill I fitted a door phone and decided to
use its naff sounding honking as the bell!
