And in the NTE5 backplate (or similar) - so if the alarm is being fitted after this master socket (hint, it's illegal to fit it before unless to a pair of terminals provided by BT Openreach for anything on the BT network, although seems to happen quite a lot anwyay with alarms) you don't need to worry about it.

sorry you have lost me a bit here!
I think I know what you mean ( I dont need to earth it because its already protected at the master socket) which begs the question why do they ask to earth the dialler

dont worry about it.
They want you to earth it to enable the lightning arrestor in the dialler to protect the dialler - as it's already (presumably) protected by something else, you don't need to worry about it.

The arrester in the exchange will only protect against surges between the two phone wires. It will not provide any protection against surges between the phone wires and ground.
Presumablly this is why the manufacturer of the alarm dialler wants an earth.

they want you to earth it because there isnt enough seperation on the pbc between the alarm components and the phone line components - if the kit asks for an earth it GETS an earth
verb.......? man just move the dialler back to the alarm panel position and use the cable that was triggering the dialler to carry the phoneline back to the diallers new position
Easy solution
yes but not where I wanted it. bottom line is I shoud have put an earth cable in when I had the chance.Easy solution
did put this topic
on the forum a few days ago but got no response, when I had time to route a cable.
what if the alarm panel is powered from that same lighting circuit from an fsu?( I know of alarm companys which take a spur off lighting circuits)

what if it isnt?
As I said before, if the earth is only to protect the dialler from surges on the telephone circuit, you don't need it unless you are taking the phone feed straight of the a and b legs (which you shouldn't do!)

I'm at a total loss to understand all this, the TEXECOM MANUAL SAYS >>
Quote " Failure to fit an earth cable may prevent proper operation of the system and will invalidate the Texecom warranty and product approval. "
Product approval, that's what Texexom have to get to be allowed to manufacture equipment that will be connected to the telephone network.
Texecom warranty, if something happens with your dialler and you send it back to Texecom for repair under the warranty, they WILL be able to tell if the unit was connected to the mains earth or not if there had been a problem with lightning.
The above speaks for its self, it needs to be earthed, MAINS EARTH, using the correct cable, NOT alarm cable.
If this is a problem for you get an electrician in.
If you don't earth the unit and there is a problem, you only have yourself to blame.
I know these units will work without the earth connection, but is it worth the risk? The lightning strike could be 1\2 mile away and you none the wiser but the dialler has been damaged.

well it could when I install it! i'm only suggesting, as I can do it that way. if so surely it would still be on the same sercuit
