I read the post about a GB type detector with a transmitter and receiver. But will it or something work with lower than 110 volts??
It's not 110v wires that I am confused by. I ran 4 pieces of telephone line to my attic, one for the telephone**, one for a burglar alarm sensor*** in the window frame, one for a smoke detector for the burglar alarm, and one I don't even remember what for.
Now the phone jack doesn't work and I want to splice in a patch in the attic instead of coming all the way from the basement again, but I don't know which of the four. I didn't label them because I thought they would never break. :( and there are a lot of empty boxes etc. making it difficult to physcially trace the wires. I can probably borrow the GB tool from a friend who installs burglar alarms. And I think it would be fun to use. If I can use it??
**The previous owner had sheetrocked over the phone jack!
***I know now, I think, that I shouldn't have used phone line to connect a sensor to a transistorized burglar alarm panel, but I had a lot of it. I read here, I think, that there is some twist in 4-wire phone line, but is it enough to keep currents induced by lightning from burning out an alarm?? I was leaving the house one day when I saw smoke coming from the keypad/control panel, and sure enough it didn't work anymore. I don't remember any recent lightning at that time, but did I make a big mistake by using phone line to connect to remote sensors? Thanks.
