looking at fitting a telecommunicating alarm.

BT line comes in from outside (ancient grey twincore), meets an ancient
bakelite rectangular "connector" box, from there wire changes to modern
black multicore, which goes off to a master socket under the stairs.
I fancy stashing the telecommunicating panel somewhere out of sight (and
using a remote kepad to control) - so can I tap into the ancient rectangular
jctn box for a new "spur" off the BT line? would I need another Master box
on that spur?

Also external phone wire is a littlle exposed from where the (recently
renewed) overhead wire changes to a short run of ancient grey twincore
clipped to the outside wall - it's BTs I know - but will they mind if I
reroute the last leg inside the house? if so how/what with?

or maybe point it in to the pointing to hide/protect it?

cheers

You shouldn't touch anything before the BT Master Socket box, so no,
you shouldn't tap into the ancient box at all.

Your own wiring should be attached to the removable face-plate on the
BT master socket, so that when you remove the faceplate then all house
telephone wiring is disconnected leaving one "test" socket in the base
of the master socket connected to the line and nothing else.

You should only have one master box on the line - it contains some
widgetry to keep the exchange happy when you have no phones plugged
into it.

Also, if you have ADSL, then you really don't want anything on the line
that might interfere with it - get a good filtered faceplate and run
everything from there.

Personally, I'd leave it, but I have altered BTs stuff in the past, but if
the cable is outdoors, then get some proper outdoor cable - the insulation
on the usual indoor stuff will harden and crack as it's not UV stable.

If thats a bugler alarm, they tend to cut phone lines before robbing
:-)

An alarm based upon a mobile might be a better bet.

Line must ONLY have one master on it at any one time and MUST have a
master on it all of the time.

3 pair, 2 pair, 1 pair, providing it is all indoors.

I re-routed the line to the pole and rerouted the entire inside section
too. In a prior rewire to that, I helped the guy wire it the way I
wanted it - saved him clambering through the loft wing.

Make a proper job of it and they will not mind - botch it and they may
make a slight fuss.

Except it probably wouldn't work if the local base suffers a power
failure. POTS is generally very reliable in such a situation.

"local base" as in mobile network local base. Very few have
significant backup power, most have basically none.

The line you mean? Fairly sure Red Care monitors for a cut line.
Wouldn't help a cut line on a dialup only system though. Pay's yer
money makes yer choice.

Umm .. most all of the ones I've seen do have backup. Batteries on small
installs and more likely than not backup generation on higher powered
shared sites...

Redcare does monitor for a cut line. There is a carrier channel on it
and if that goes they start asking questions;!...

Not the local cell (note singular) for here. Last time it lost power
two of the networks disappeared straight away, one lasted about 5mins
the other a few hours. Worse was when the power came back on, one
network came up straight away, another after a short period, the last
two took nearly 36 hrs... These cells are sharing an Arqiva mast with
the local TV relay and quite a bit of other point to point links as
well. Not a cabinet at the bottom of a lamp standard type cell.

Well I can only comment on what's in our area .. up in the frozen
wastelands of the North perhaps they don't bother?..

Thieves can plan your line to be cut, but they cannot so easily plan
cell outage to suit their activities.

I work in banks, an early indication of a possible attempt at robbery
is the phone lines failing.

cartainly, a theatrical equiment hire comopany I know has arranged its
alarms to go via a mobile phone. As you say, POTS can easily be cut.

But presumably on instructions from the accountants, Redcare is quite
expensive compared to POTS or a little used mobile account. Just make
sure it's contract not PAYG so it doesn't quietly stop working after
3, 6, or what ever other arbitary period the provider decides upon.
And also makes sure that accounts know not to cancel this contract
mobile phone that is never used...

Redcare uses the normal telephone wire, but like ADSL is on a carrier. It
has nothing to do with mobile phones. And, actually, it had nothing to do
with the accountants. The diretors (owners) who I know quite well, took
this decison after neighboring warehouses were broken into, after the phone
lines were cut. Redcare would show this up, of course.

There are a few specialist suppliers around who do SIM's at very low
cost monthly rates but charge full rate for any calls made on those
accounts...
