What's Included

  • SignaLinc™ Plug-in Coupler-Repeater
  • Owner's Manual
  • More Info

    The SignaLinc Plug-in Coupler-Repeater simply plugs into an existing clothes dryer outlet. Unlike previous solutions, which typically involve hiring an electrician to hardwire a signal bridge or installing a capacitor inside the breaker box, the SignaLinc Plug-in Coupler-Repeater can be installed just by plugging it in! It includes a feed-through outlet for your existing dryer to use so you won't block the outlet for your clothes dryer.

    Why you Need SignaLinc Plug-in Coupler-Repeater
    Because most homes have 2-phase 220V power that splits into two separate 110V legs, sometimes X10 signals have a hard time making the transition from one leg to the other. Simply plug a SignaLinc Plug-in Coupler-Repeater into your home's 220V electric dryer receptacles and it will detect and amplify X10 signals between the two power lines in your home.

    Better than the Passive Signal Bridges
    Because this unit actively amplifies or re-generates the X10/PLC signals, your receivers will get a stronger signal than what they would have received directly from the originating transmitter via the non-amplified signal bridge. Homes with large installation of X10 products will see an immediate improvement in response. No longer will you have a module stay on all night because the OFF signal was too weak to trigger the module.

    Diagnostic Indicators
    The SignaLinc Plug-in Coupler-Repeater includes four indicator LEDs on the front of the unit. These indicators show the status SignaLinc's processing of the powerline signal. The red and green pairs monitor each phase separately and illuminate when X10 signals are detected and re-transmitted.

    The SignaLinc Plug-in Coupler-Repeater is available for 4-wire dryer outlets. Once installed, it remains easily hidden behind the dryer.

    Safety Tested and Factory Certification
    All SignaLinc products are safety approved. The assembly line for Smarthome Design Products is ISO9001 certified. In order to meet the ISO 9001 standards, the entire factory underwent rigorous inspections of procedures and policies before being thoroughly audited. The certification received was based on its dedication to high quality management systems and strict adherence of quality systems and guidelines.

    Works well with X10 devices.
    TODD -- quakertown, PA   10/28/2012
    I was having major issues with signals not getting through to several wall switches and lamp modules due to my Verizon FiOS boxes which seem to eat X10 signals. This simple little device took care of that! Now, everything works as it should.
    Todd -- quakertown, PA   10/6/2012
    Ever since we switched to Verizon FiOS, their HD boxes eat X10 signals for lunch. I had the most erratic system and stopped using the Activehome Pro interface because 1/2 the system didn't either turn on or wouldn't go off. I also had an annoying issue with a small lamp on my foyer table that wouldn't turn on or off if the adjacent laundry room light was on 2 CFL bulbs. After installing this coupler/repeater, there are zero issues with my system. Every signal gets through now and I reconnected the CM15A interface with no problems. This is the best $$$ I've spent on this system.
    Alexander -- Cali Colombia   10/4/2012
    Hello! I have 45 SWITCHES for lights in my house. The status report behaves very slow on occasion. Anyone know how I can improve this. I like to know if the lights are on or off. thank you very much
    JERALD -- garland, TX   8/29/2012
    Great product for my X10 system. Greatly improved the functionality of all my modules and controllers.
    JOHN -- houston, TX   7/16/2012
    This device is subject to failure over time. Was having problems and because device had failed previously ordered one and within 1 hour found a different source of the problem and tried to cancel order. Could not, even though order not even submitted for shipping. Got note from customer service end of next day and was told it had shipped, which by then it had and if I paid all shipping fees I culd get a refund. Not worth $100 effort! Unit will be needed sometime but cancelling an order is impossible so don't make a mistake!
    Mike -- kokomo, Indiana   7/7/2012
    I've had problems with X-10 modules on different phases of my house wiring for years. I finally installed a SignaLinc Coupler-Repeater today. It works great.
    FORREST -- rock hill, SC   7/2/2012
    Best recommendation - You plug it in and it just works.
    DAVID -- leander, TX   5/31/2012
    Solved my signal loss problem. Sender and receiver only 20 feet from each other in east end of home but could not see before installing this in laundry room in west end of house.
    Kevin -- pittsburgh, PA   5/5/2012
    I installed the signalinc with 1 booster-linc module, and two filter-linc modules. They made my X10 signals highly-reliable however the repeater created another problem when automating lighting via smart macros. I learned that you have to place 2-3 second delays in between signals or the repeater flakes-out and floods the home with a storm of X10 signals -- to the point that your system is completely inoperable until you unplug the 4826a from the wall. Note: I can also create the broadcast storm by hitting buttons quickly on my X10 RF remote. I could not do that prior to having the repeater. It is possible that the boosterlinc is helping the X10 broadcast storm to be more likely because it continually boosts the repeated signal and probably helps to create an endless X10 feedback loop. I plan to do another test without the booster-linc to see if that helps.
    VINCENT -- village of palmetto, FL   5/3/2012
    The Signalinc Repeater did the Job! X10 signals work better than ever. Easy to install, just plug in. The unit is large, So I used Cable Ties to Relieve the stress on the Signalinc from the weight of the Dryer Cord.
    DAVID L. -- belfair, WA   4/14/2012
    Works fine, a bit confusing on the shipping though.
    DONALD -- san diego, CA   3/24/2012
    It did not cure my situation where some of the lights would not switch on and off when they are supposed to. The unit did not increase the signal on the system.
    ROBERT W. -- dunwoody, GA   3/17/2012
    The SignaLinc Repeater 4-wire dryer did not overcome the issues I was experiencing with my X-10 signals. I further had a 3-wire dryer plug and receptacle and had to replace both as the 3-wire SignaLinc Repeater is no longer available.
    TRIET -- houston, TX   3/9/2012
    Dead on arival, return for another unit, Customer is excellent
    JIM -- ottawa, ON   3/3/2012
    Seems to have solved the problem. Well built, extremely easy to install.
    GARY -- bowmanville, ON   2/2/2012
    Excellent product, works exactly as described. This my second one, the first died after 4.5 years of use.
    DAVID C. -- tifton, GA   1/7/2012
    Even though the SmartHome tech told me it would, the repeater didn't fix the problem. It turns out the problem was in the CM15A USB Computer Interface. I have not found a new one to buy so I just wasted $100.00 and my entire system is dead.
    RICHARD -- warrenton, VA   12/30/2011
    I was having a lot of problems with X10 signals failing in my new home. Few of the lights turned on the first time I tried to connect. The system was so erratic that I was considering dropping my X10 applications entirely. The SignaLinc repeater has completely eliminated dropped signals and my lights work great! A little pricy but worth every penny!
    JAMES -- uniontown, OH   12/22/2011
    Great, works as advertised.
