How to Secure Telephone Wiring

    I realized that the outside telephone wire that our alarm uses is venerable.
    We have above-ground utilities and the tele company box is easily accessible
    via a standard screw driver and the line runs openly along the siding just
    3' from the ground - then into the basement wall of the home. How does one
    protect the wire from simple clipping?

    Since we also have smoke alarm detection, I also thought that it is also
    venerable to fire. How can I ensure that the station will be called if a
    fire starts and burns the telephone wire before the alarm is tripped?

    I'm thinking that I may need get a dedicated fire-protected line (if one
    exists) from the pole that runs higher off the ground (or underground) to
    also protect from cutting. Is calling the phone company to do this the
    solution, or is there a simpler way?

    Where can I find out more about the cellular backup? I own a GE Simon v3 (if
    that matters).

    This is one of the better posts on how to resolve this. I would like to add
    a couple of comments. Use either PVC or IMC conduit between the pole and the
    home. EMT or regular steel conduit does not hold up well underground. Do not
    run the conduit up the pole just stub it out a few inches above ground level
    and have the Telco install a metal U-guard up to the 12 foot level (two
    pieces of standard 1 inch u-guard.) Do have the Telco install a NID on the
    pole at the top of the u-guard the tech may grumble but this is why they
    have ladders on the truck. DO NOT install any foreign attachments
    (protectors etc) on any joint use pole both the power company and the Telco
    have the right to remove these without any warning. Between the pole and the
    home be sure to use gel filled cable or have the Telco pull in a buried
    service wire. There will be a charge for this but compared to the cost of
    obtaining a roll of gel filled cable the charge may be substantially lower.
    Inside the home install an additional properly grounded and bonded protector
    per NEC again you can have the Telco do this or DIY as it is beyond the
    DEMARC. And speaking of which keep in mind all of this wiring will be beyond
    the DEMARC and is the responsibility of the building owner to maintain.

    I thought there was a way to supervise lines. For example, my AC plug for
    the Simon v3 came with a small resistor that apparently attaches between
    both wires, so that if snipped, it will trip the control panel and alert the
    CMS. I think that's how it works.

    How does this resistor work, and can I use this method to supervise
    telephone wire too?

    Well, anyway, the alarm can't call me if the line is cut anyway. Duhhh to

    I don't know what I was thinking about - I haven't used steel conduit in
    years... use the electrical pvc pipe.
    I also didn't mention to do this on private poles; on a telco pole or
    electric co owned pole they do need to
    install U-guard on THEIR poles. I don't know what the situation is in other
    areas but many poles here are
    private poles.

    Oh yea, that's the idea - to get the siren to blow.

    Almost anything goes on spot poles as they are installed on the owners land
    at the owners expense and while they may or may not belong to the owner he
    is pretty much to free to do with as he pleases.

    If one is trying to provide protection from hand operated tools such as
    shovels PVC will provide moderate protection, while IMC and rigid provide
    the best protection. When mechanized digging machines are in the mix nothing
    short of reinforced poured concrete will provide protection. In underground
    utility locating a backhoe wins every time.
