I have a castle care-tech MESSENGER, I want to connect to my alarm panel to send a SMS to my mobile when my alarm is activated. The Instructions for wiring the telephone line aren`t too clear, can someone enlighten me...

There are five input terminals..

1. Line A IN

2. Line B IN

3. Line A OUT

4. Line B OUT

5. Telecom Ground.

The Diagram says connect to terminals 1 & 2....

Can somebody tell me which telephone wires to use? I looked in my telephone socket and there seems to be three connected, I presume one of them is Telecom ground. How do I tell the other two apart?

Mike

he there you need to conect A TO 5 AND B TO 2 AND GROUND TO 3 HOPE IT HELPS

HI YOU CAN CONNCET EARTH TO 4 THATS THE SIGNALING EARTH

Ummmmm.

I suggest you check out BT wiring, there's lots of info on the internet.

My understanding of a normal domestic setup is:

1 and 6 are NEVER used.

2 and 5 are the main circuit, don't think there's any specific polarity.

3 is the bell signal. This is generated by the components in the master socket.

The external wire to your house will have only 2 wires.

THERE IS NO EARTH.

4 can be used as an earth in some commercial PABX installations.

5 can also be 0V or earth in some systems.

Hope that helps.
