Essential Info

Don't miss out on an important phone call or visitor because you were watching a movie on your thundering home theater or cranking up that killer audio system. Find out when you have a call or visitor with a flashing lamp or an activation of any other electronic device with the Elk Doorbell and Phone Ring Detector! This versatile unit detects ring activity from up to two doorbells and a single phone line and closes a low-current contact (open collector) that can be used to trigger any number of events or macros using your home automation controller!

If someone presses your doorbell, program the lights to gently fade on. Or, if you have a hardwired IR distribution system, program it to automatically lower the volume when the phone rings. If your home control interface has an "away" feature (like the HouseLinc system), you can bolster your home's security by turning the stereo on when the doorbell rings, or activating the front door security camera and time-lapse VCR that it connects to. The possibilities are endless!


What's Included

  • Doorbell and Phone Ring Detector
  • More Info

    Compatible With Most Home Automation Systems
    The Doorbell and Phone Ring Detector works with the most common home control systems, including the Stargate, TimeCommander Plus, HomeVision or HouseLinc 2 with a Digital BOB. It works with any X10 system when combined with an Powerflash Module. It will also work with any INSTEON system when combined with an I/O Linc - INSTEON Low Voltage / Contact Closure Interface.

    The unit simplifies installation enormously thanks to its pre-scored circuit board, allowing you to snap off the individual detectors. Install the doorbell detectors anywhere in the wiring loop, and the phone detector near easily accessible phone wiring. No need to fish all of your wires to the same location! Both the doorbell detectors and the telephone ring detector get power from the lines, so no external power source is required.

    Works like a charm. Rarely misfires. May require electrician to install, if you don't have basic skills.
    MATT -- poughkeepsie, NY   8/5/2012
    I used the doorbell trigger module to setup my Insteon/Homeseer to detect a doorbell ring which will snap an image from an outside camera. Works exactly as described and was easy to install with directions provided
    JEFFREY -- saint albans, VT   3/12/2011
    This item was worked very well. I like how the circuit board was scored and you could split the board into 3 parts, which was very helpful since I could use it in different areas of the house at the same time. A bit on the pricey side though, so I gave it 4 stars because of that.
    JONATHAN -- maryville, TN   12/12/2009
    The product was just what I needed for the telephone part, however, I didn't need the doorbell circuits. I should have looked further for just the telephone. Thank You Very Much. Jon

    Still working on setting it up directions were a little confusing and I forgot to order the X10 component for setting it up
    JOHN -- coopersburg, PA   8/3/2007
    Product works well.

    Great product!

    Excellent product! Documentation provided with the product was not sufficient but information was easily obtained from the manufacturer.
    LARRY -- oklahoma city, OK   7/4/2005
    works great
    WILLIAM -- falls church, VA   2/16/2004
    It does just what I wanted, and works exactly as I expected from your web store description. The only thing I could wish for is a way to get a second telephone ring detector without having to buy a second whole "DOORBELL AND PHONE RING DETECTOR" (because I have 2 phone lines). But if this works well for a month, then I will probably buy a second one anyway.

    Some more information about the voltage rating would have been useful
