Can you effectively 'lengthen' a wire run?

Kurt

My house was completly pre-wired for a security system when it was
built. I am now in the process of installing the hardware and I ran
into a snag. I installed the first of 3 keypads (Ademco 6160) right
where I wanted it by the garage door, but it didn't seem to be getting
any power. When I called the electrical sub that did the work, he said
that he had accidentily ran that keypad wire (CAT5) from the control
box to the utility room, which is about 5 feet away. Rather than run a
new wire to the correct spot, he simply ran a separate piece of wire
from the utility room to where I wanted the keypad. Therefore, the wire
I just connected to the keypad ends in a wall in my utility room, right
next to the wire that runs back to the control box. He said all I had
to do is splice the two together, or "for a fee" he would come do it
for me. I was always under the impression that splicing CAT5 was not
recommended. Can anyone give me some advice on the best course of
action? I really don't want the keypad in the utility room.

Cat 5, though not really the proper wire for this application, may be
spliced in this case with no problem. Make good connections, and insulate
them well.

CAT5 shouldn't be spliced if it's being used for a PC network or even a
telephone system but for a keypad it might be alright. The sub should have
made the splice, call the electrical contractor and ask why you should be
expected to pay this "fee" because his sub didn't finish the job.

Not quite. For data networking, correct. You definitely can splice it if
it's used for telephone circuits or your alarm keypad.

Not quite. The twist helps eliminate crosstalk on telephone lines.
On that we agree. I can't believe this jerk had the nerve to try to exact
additional payment for fixing what he did wrong. Are you sure this guys
isn't from Brooklyn?

I liked the way I said it better.

I disagree... please don't deluge me with a long diatribe of how technically
you are correct and you really meant that...

The standard for commercial applications is to install network and telco
wiring in commercial application to the same standard. This is because of
the blurring line between I and T of IT. Now to go on slightly.. for POTS a
spliced line will work fine and beanie connector will work just fine,
however, I have seen UY connectors used on basic digital key system wiring
and the circuits failed. We replaced them with UR connectors and it worked
marginally to good.

So, your broad statement is incorrect, but for a residential client splicing
wiring for a POTS line with UR or beanie connectors shoudl cause no
problems. For his keypad because of the low speed data and basic power
being transmitted to the keypad he should be able to splice the wires with
properly isntalled beanie connectors and experience no problems.

As a side note. All of my institutional clients with their own IT personnel
have me install Cat 5(x) and telephone wiring to the same standard. .

Thanks for the info, guys.
I went down and bought some UR connectors.

p.s. I didn't mean to cause any arguments. :-(

Untwisted "station wire" has been used for telephones for many years with no
ill effect.

Around here 'crosstalk' is an ill affect.

You didn't cause anything... This war was raging when I first popped in here
a while back and caused me to leave for a while... Let us know how your DIY
installation works out.

Station Wire pairs are twisted, just not as tightly.


But he wouldn't know that. "Running a small modestly successful central
station alarm company" doesn't mean he installed diddley (or knows much
about such things)...

And now you're back - since RLB announced his leave. Good.

When did he announced that he is leaving?

since he is in my plonk list i rarely see some stuff from him..

Since for some strange reason he feels compelled to announce to the group
everytime he manages to prise himself away from his computer be it to take
a
leak, answer the door, host a party or take a trip somewhere, I'm sure
you'll get another chance

I fear that you are right..;-)

I thought I'd let everyone know I will be away for a short time taking a
dump, my next posting will be after this task has fully completed

Thank you

Don't forget the task isn't complete until the paperwork is done. ;-))

He's been in there a long time Frank, someone better go check on him.


You go.
