ok let me try and make this as short as i can......

I have a ADT Pro 3000EN security system which ADT monitors and i pay them each month. i think its also ref to as then vista 20p?? am i right???

anyway the problem is that my dad rewired all the phone lines and to make it short now i have a comm failure message on my keypad??? i dont know about how to wire a rj31x phone jack(if thats the jack that adt used in my system that is?) so a dont know where to problem is? i think its at the other end of the phone line but he connected the phone line to the end of the wire that adt put in so everything looks ok? i tested the dailtone in the rj31x jack and the black and red wire pair had a dail tone using a dailtone tester i have? oh and the 2 pair wire adt used has black, red, yellow, blue colored wires so the back replaces the green wire which is connected at the end of the phone line to the active phone line so u will see a back wire connect to the main red wire.

i started playing around with the jack and plipping the wires around and nothing, it looks like the wires loop at the rj31x jack and i have know idea why so thats why i cant fix whatever my dad did wrong and put it back to how it was when adt wired it so now it prob doesnt even signal adt saying my alarm went off!!!

can anyone help me i know there is a trick to wiring a rj31x jack, what is the trick and what do i do at the end of the phone line to the 2 pair red back, yellow and blue wires? or lets say just the blue and yellow wires because they are just deconnected at the end????

 

If you follow the link in the FAQ for RJ-31x wiring, you can get the proper wiring diagram.

What he probably did was disconnect the incoming line that's supposed to be on the incoming side of the RJ-31, but left the outgoing line connected. You would detect a dialtone at the panel, but when the panel tried to dial, the line siezure relay would effectively disconnect the panel.

 

RJ-31x ok i plugged in RJ-31X and didn't get anything in the search but googled it and got some info of what a rj-31x is and what it does. now i looped everything at the main line and have everything in a loop the thing is i played around with the rj-31x module yesterday and flipped the wires so i dont know if its working but the wires are loopped but the think is the module looks different the the other modeles that i looked up on some websites.

the website ones have 8 strews and this module only has 4 screws, i have everything thing hocked up and i get a dail tone with the bord connected and with it not connected to the rj-31x jack and i still get a comm failure at the keypad? when do i know that i got it right? do i have to reset anything or do i just have to get those wires in the module connected the right way then it will just stop showing the comm failure message at the keypad?

 

In most situations, only 4 of the 8 connections on the jack are used, and there are versions of the jack made with only the 4 terminals. Red/Green is incoming, and brown/black is the house line return.

Any changes he made were probably made at the NID. Put everything at the RJ-31x jack back the way it was. Make note of which wires were connected at the red green terminals and which were connected to the other pair.

At the NID, the phone lines coming in connect to the incoming line to the jack, all of the house phones connect to the other pair.

 

well the thing is that i was playing around with the wires in the rj31x jack so now i dont know what goes with what but i think it is fine know but how do i know if its working?? do i just go and check the keypad and check to see if its not showing the comm failure error? because if thats so i must have fliped the wires in the rj31x 100 times and ran up and down the stairs to look at the keypad to see if it was showing the error, do i have to reset something or if the message is still there i still have a line problem?

 

Even if you have it wired correctly, Ademco tech alarms still have to have CODE + 1 entered to clear the display. You may have to enter it more than once.

A quick test as to if you have it right: Unplug the alarm cord from the jack and plug a regular phone into it. If you have it right, that phone will have a dialtone, but none of the other house phones will.

 

yeah i know that you have to enter code then 1 but something is not right here so i just hardwired the inline and outline to the main bord to see if it worked by testing the alarm system by tripping the tamper switch in one of the wireless door contacts and it seased the main line and did its thing. i called adt and they got my trouble signal..... got off the phone with them and now i know its not the programed number in the programing so it has to be that module??? the module has only 4 screws not 8 and i dont know where to connect what to because i flipped all 4 wires around trying to make it work.

i did get it to work somewhat the wrong way..... i wire it a way that it works but when i listen to the line on a house phone and trip the tamper switch i hear it dial out to central station do its thing then desconect. so it works that way but i dont think im supposed to listen in???? oh and i just have one pair connected to the nid box and thats how i got it to work that way... its just one pair at the nid box and one at the module. before i had 2 pairs at the nid and was trying to connct it at the module to make it work yesterday but gave up? whats going on with this? its driving me crazy? i no the basic steps to programing a system and stuff because of trying to figure this one problem in like 2 weeks and became tech smart from reading so much stuff on this form but still cant get it to work like it did before my dad started remodeling the house. i'm guessing that the adt tech that wired my system in 2003 didn't want to wire the rj31x module the way i see it wired in diagrams that i have seen on this form. i have seen it online done with 8 screws and 2 pairs of wires being used on both ends... but i think the module isnt like a rj31x module it uses only 4 screws and i think only needs one pair of wires at each end to work? am i going crazy or is there another way of wiring ur system a different way other then using rj31x module 8 screws?

oh and i cant test the module by connecting a phone to it because it is a larger pin connecter dont know what u call it but its the ones that you use to network computers with?? so how have i test it?

 

Regular RJ-11 plugs fit into a RJ-45 size jack. That's the whole point. We only wanted to connect to the center pins, but not to the two outer pins that the dial tone is returned on.

I'm sorry that I cannot seem to provide you with an adequate description of some basic wiring. I wish you luck.

 

just got it, lol

thank you so much for helping me this past week. after spending nights on it i figured out the problem.

for other people that have this problem i'll explain alittle bet what i did.

must people use the rj31x module with 8 screws and its already color coded for you. all you do is put the 2 pair in and out lines a in the color coded module lines.

now my problem is the adt guy mad my life harder because of his different colored wires. i had to deal with different color wires at the alarm bord screws to the rj31x module then the wiring inside the module itself was different colors then the 2 pair wire that he used all the way to the nid box was another different colored pair wires.(laughing out loud!!!!) so that means i had to get everything right to make it work. so at the end of the night i was like oh hell with this let me see if i can do it another way, so i took a closer look at the rj31x jack itself and looked at where the module wires inside connect into the female pin. its realy hard to tell but u have to look close at it and see what color are the right and left wires that go into the whole and what are the center colored wires that go into the whole from there i color coded everything onto a piece of paper and color code 3 exchanging 22 different colors and now all the wires that go from the nid box all the way to the bored match and there u go now it works!!!!

now that i did my first rj31x module myself i will do it faster the second time. for people trying to do it yourself just use 4 different color wires for everything!!!!! even if your alarm comes with its own module and wiring from the bord to the model use just 4 tipes of colors or fined matching ones.

meaning your bord wires are red, green, yellow black, module wires are red green, yellow, black, long extended new wire that goes all the way to the nid box also red, green, yellow black. you get the point now!! like that its all plug and play.

thank you all for your help now that i did it, its is easy but when i started all i wanted to do is kill myself!!
