Dual Port BT Wall Master Socket – 5/4AIDC punch down terminals & instructions for easy installation. Extension socket size is 86mm x 86mm (fits a standard back box) and is supplied with fixing screws.PLEASE NOTE – This listing is for 10x wall plates, multiple views may be shown in the picture above.Used for - This BT master socket should be connected to the main incoming telephone lines into a property, it cannot be used as an extension socket. This wall plate has 2x outlets on the front allowing 2 phones to be connected to the same line. It also allows you to plug 2x extensions sockets into the one plate.How to fit - The BT drop cable coming from outside the property usually has orange, white, green and black wires. Usually (but not always) the orange and white internal wires are the active pair and go to connections 2 and 5 on the master socket, in some master sockets these connections are marked A & B. If you are removing or changing your current master socket, you can check which wires are the active pair by looking at the original wiring. Which way round the internal wires are connected does not usually matter, however the polarity can sometimes stop some equipment from working. One of the cables will have a voltage of -48V and this needs to go to pin 5 (B) and the other will have a voltage of 0V and this needs to go to pin 2 (A). Voltage can be checked by using a multi-meter, if you do not have one, they are available in our shop. Connection of the active pairs into this master socket can be done using a screw driver and its screw terminals. The BT drop cable has more than 1 pair of internal cables therefore, this is for if you wish to have 2 or more lines in your property, or if a pair fails, the chances are that there are still existing pairs available, hence there would be no need to replace the drop cable. Can be surface or flush mountedScrew termination pointsFixing screws suppliedStandards - ROHS Compliant.
