Mum has just bought a new flat and is finding that the buzzer on the
intercom in her flat from the main door is not quite loud enough for her
when she is in the living room, particularly whilst watching TV.

I have no experience of such systems whatsoever and wondered if there was
a simple way to either increase the volume or, alternatively to have an
additional buzzer sound in her living room?

I guess it would be something an electrician could sort out quickly??

TIA

There may be extension buzzers available for the system that can be
wired in, but a baby alarm with the pickup near the buzzer ought to work
well enough.

depends on the system, but most use small AC buzzers similar to

http://www.videx-security.com/products/door-entry-systems/traditional-systems/accessories-c/ac-buzzer/

*most* will supply 2 or 3 buzzers in parallel. You might want to
rectify the AC and use a more melodious DC sounder that has a lower
current draw eg

some systems use an audio tone call and they would require an
extension speaker - and not all systems would support this.

If you can identify the make of the system that would be helpful.

Entryphone(tm) suggest using a small friendland bell or buzzer and
I've used a friendland ding-dong on an intercom system. Although the
system supplies 12V and the bell is rated for about 8V the rings are
usually of short duration so both bell and power supply cope.

Thanks for this Owain,

Next time I'm up at Mum's I'll see if I can discover more about it. I've
saved this post for future reference and may get back on it in a couple
of weeks time. In the meantime I'll suggest she tries Colin's suggestion
(thanks for pointing out a possibly simpler solution Colin) of a baby
alarm, there's a friend in the area from whom she may be able to borrow
one to see how she gets on with it.

Is this a new "new" flat?

I was just thinking about cable runs.

And the next time you are up there get a model number and have a look inside
the intercom, the buzzer may (long shot) be adjustable.

If its an audio tone of some sort fed to a speaker, you can always
connect a computer speaker to it, even if you cant connect a regular
passive speaker. You may need to use a resistor or 2 to reduce the
voltage into the pc speaker.

I'd have thought a disability organisation might be able to point you at
this sort of product. Often not cheap though.

You could I suppose start delving into the system, but if its a comunal
device then you could be treading on some toes here.

I suppose if doing a diy thing, then a radio doorbell with the buzzer on the
intercom rectified and used to operate a relay to replace the bell push
itself. Some of these devices can be worn in a pocket or on a belt.

No, purpose built about 15 years ago with the intercom by the flat door -
at the end of a loooong hallway to the living room. A bit of daft
planning originally - a repeater buzzer could have been easily installed
as part of the original wring spec
