Multiple BT points...help..

[Peter1891]

Evening chaps
I’m first fixing a new build this week large high spec 4 bed house.
The builder would like multiple bt points throughout the house what’s my best way of doing this as I’ve not done a lot of it.
Should I make one the main one then daisy chain off the rest like a radial?

1st one is master, usually installed by BT. then just daisy chain slaves from there. you should not have more than 4 slaves from a master.

High spec?
Surely you’d be running Cat6 if so and forget the 3 pair.
It can be used for any number of purposes then.

Hi, there is 4 in total on the plans two in front room one in main bed and one in family room, how will I know which is to be the master? Would I be installing the master one?

no the master is installed by BT, if you had read my earlier post.

I did read your earlier post.
im assuming bt wont have installed the master by the time I arrive so how do I go about wiring the ones on the plans do I run the cables back to one I assume will be the master socket?

i would think so. you only need to wire pins 2 and 5. leave cable at master point and connect once master is installed.

Ok thank you for your help. It’s only first fix stage so I’ll just be running all the cabling not connecting anything up at this stage, I’ll daisy chain from what I’ll judge as being the master maybe a front room one I suppose?
Thanks again.

You should wire 2 3 and 5 if you want the bells to ring. It is good practice to wire all six if using 3 pair cable to CW 1308.

There is no limit to the number of sockets you can wire in but the old rule was that the maximum REN of the phones plugged in should not exceed 4. REN is ringer equivalent number and used to be used when phones had 4 k ohm bells to limit the amount of current drawn from the exchange. With modern phones I do not really think it matters too much now.

Remember that you should use secondary sockets for everything except the Master which should be provided by BT or the line supplier.

A secondary socket does not have a ringing capacitor, opt out of service resistor or a lightening suppressor.

Thank you very much. Still unsure as to how I’ll determine which of the 4 bt points on the plans will be the master if I finish first fixing and bt decide to put the master somewhere else I’ll be screwed

You or the client should tell BT where to put the flaming Master Socket. The standard price for a new BT line does not vary with the length of cable run

BT will put the master wherever you ask them to, it makes sense to have arranged it with them beforehand to establish what is required from their point of view.
Remember BT will stop installing copper services soon in favour of fibre services.

If you don't arrange anything with BT you may find that they come in and run a surface cable around the inside of the property!

It doesn't, but the BT operatives are expected to complete a new service install in a specific time regardless of where it is being installed or how much work is involved so they tend to work as quickly as possible (and to a low standard)

There is no limit to the number of slaves you can have, the only limit is on the total REN of all connected equipment.

Ok great thanks. I’m starting first fix tomorrow so I’ll speak to the builder and/or bt too.
