  • Seizes phone line in event of a breach of security

Essential Info

Your security system is in place to protect your office, home, and loved ones. In the event of a security breach, your security system uses your telephone line to dial for assistance. Burglars may be aware of this and try to circumvent your system's success in alerting authorities by picking up your phone, but Leviton's RJ-31X Surface Mount Jack will seize the phone line, so burglars can't prevent your security system from dialing out. The phone line simply goes through the RJ-31X Surface Mount Jack.

    Solidly designed.

    It's a little big, but the main problem is that it did not come with any wires. I had to buy a 1ft Cat5 cable, cut it in half and strip the wires to use this jack.
    ROGER -- glendale, AZ   5/25/2012
    The jack worked fine but I was a bit dissapointed in the documentation. however, thanks to Google I was able to install the jack with no problems.
    JEREMY -- fort worth, TX   2/27/2012
    Works as described. Pigtail-ing a cat5/5e/6 to plug into the rj-45 connection to the alarm panel works well.
    MARK D. -- pahrump, NV   5/19/2011
    Product does not work as advertised. Documentation is horrible. Smart Home technical support was no help. Avoid this product.
    mr dave -- pembroke, ontario   3/10/2011
    Description is slightly misleading... An RJ31x jack allows a reliable way to insert an alarm system that has line seizing capabilities between the building's incoming phone line and the various phones throughout the building or house. In normal conditions, the alarm system simply lets the phone circuit pass, and in an alarm condition it seizes the line so it can call the monitoring centre whether someone is using a phone in the building or not. Should the alarm system malfunction, removing its cord from the RJ31x jack restores normal operation of the phones. Line seizure is a function of the alarm equipment burglar/fire, some personal/medical alert systems with the proper cordset, etc, not the RJ31x jack.
    WILLIAM -- austin, TX   1/7/2011
    This is a tiny but necessary item. It came properly packed and in excellent condition.
    MILTON -- desoto, TX   9/30/2010
    Great price, timely delivery, useable instructions.
    BATSHEVA -- manalapan, NJ   10/1/2009
    Didn't com with any instructions for installation. Installed in. Worked like a regular jack. Didn't seize the line (like I expected it to), for use a lifeline alert system. (I guess I didn't install it right.)
    PHIL D -- everett, WA   5/12/2009
    I had purchased 2 other RJ-31X Jacks that were CLONES of the Leviton. They were GARBAGE. These Leviton originals are such higher quality, and will not break or malfunction under normal repetitive use. A+
