Essential Info

When a visitor presses the button on the door intercom, the DoorBell Fon rings the phone in your home with a distinctive ring to alert you to visitor's peresence at the intercom. Pick up the phone to converse with whomever is at the door or if you are on the phone when a visitor arrives a call waiting tone will sound to alert you. In fact, the DoorBell Fon system will even work without phone service as the system provides the necessary voltage to operate on its own.


What's Included

  • 1x - Door Answering System - Ivory
  • 1x - Control Unit
  • More Info

    Up to two intercom stations can be attached. Add an optional Electric Lock Controller, electric door strike, a corresponding power supply and you can unlock the door from the phone by pressing "*". Easy two-wire connection to door intercoms. Works with answering machines, most home PBX phone systems, and phone-company provided services like voice mail. Includes one door intercom station, which measures 3 7/8 inches X 5 1/8 inches X 1inches, and a power supply.

    Expand your intercom system with these optional accessories:

    Electric Lock Controller
  • Add this optional lock controller, an electric door strike and power supply and you can unlock the door from the phone by pressing "*". A seperate power supply is required when using a doorstrike. See the doorstrike page for a recommended power supply.

  • Doorchime Interface Module
  • Provides 800ms of dry contact contact closure, and is simply bridged to the door box leads. Activated by the push button on the door box, it's perfect for integrating a door chime, activating a camera, or turning on a light with your DoorBell Fon system. Requires two AA batteries, included.

  • Ring Extender
  • Increases the number of rings the DoorBell Fon will provide from three to eight. Normally, after someone presses the button on the outdoor intercom station, the phone will ring and there be approximately 20 seconds available for you to pick up the telephone and be automatically connected to the doorbox. By installing this chip, you'll have a total of 8 rings or about one minute.

  • Intercom Awning Single Gang
  • If your intercom is not located under an awning, we recommend that you purchase this awning specifically designed to protect the intercom against direct rain and snow.

    RAY -- north venice, FL   2/7/2014
    This product was shipped promptly, and had excellent installation instructions. It was also very reasonably priced.
    WILLIAM -- kailua, HI   11/15/2013
    I replaced a 10 year old door bell-intercom unit so no new wiring was required. Simple installation---product worked perfectly as advertised.
    ALEX -- derby, KS   10/10/2013
    Easy to install, for a novice and very very easy for a qualified or professional and works better than expected.
    DAVID -- palm springs, CA   10/9/2013
    product works as described and installation was easy as per instructions
    BRIAN -- lafayette, IN   6/20/2013
    Works as advertised
    DALE -- scottsdale, AZ   6/6/2013
    Very good service. Good price and and delivered as expected.
    STEVEN -- angola, IN   6/1/2013
    Everthing went very well as far as my order and the insallation went. But the e-mails to follow after my order is to much. Thank You.
    CARL -- greenville, SC   2/25/2013
    very good
    NORMA J -- oneill, NE   1/26/2013
    This is my second doorbell answering system purchase. It's being held as back-up for if and when the first one -- several years old by now -- might fail. The bottom line is I can't be without it. As a handicapped person who helps run a rental business for my brother, the intercom saves me from falling and/or missing a client on a daily basis. It's a wonderful and affordable product. Installation does require phone system knowledge.
    Tuna -- Florida   10/11/2012
    This will be the third unit I will have purchased over the past 3 years. They just do not last. Unfortunately there is no other competing product with this feature set.
    THOMAS J -- port orange, FL   10/1/2012
    Arrived on time. Had questions on install and were answered quickly and correctly.
    LILLIAN -- asheville, NC   9/24/2012
    Great Item. Filled a real need. We opted to replace the the 3 ring chip with an upgrade to the 8 ring chip from the manufacturer and love it. Although it does not have a unique ring, on our phones the caller is totally blank so we know it is the doorbell phone.
    GEORGE -- loveland, OH   8/2/2012
    This device works well. It is very useful for a person in a wheelchair who cannot easily get to the door when someone rings.
    CHET -- bolivar, MO   5/13/2012
    These units are great! I've installed one in each of my three homes......well made, work well, and simple to install. Manufacturer tech support helped when there was a slight problem (on my end.)
    JAMES -- yorba linda, CA   4/1/2012
    Does everything is says. Easy install and dependable.
    Ted -- toronto, Canada   1/25/2012
    I have rarely come across a product that made such a positive difference in the way our home operates. Now we can hear and answer the door from any room, even from our back yard. It was worth every penny. I was also amazed at how remarkably easy it was to install. I am only surprised that more people haven't heard of the DoorBell Fon.
    JEANNE E -- irvine, CA   12/23/2011
    A rather dated design yet functional. Somewhat overpriced, especially the extras like the door chime unit. The unit seems a little sensitive to the occasional erroneous call.
    JAMES -- milwaukee, WI   12/15/2011
    Product as advertised. Works perfectly. Delivery was remarkably fast.
    Loaded4th -- Irvine   11/27/2011
    Great concept and works well. Design/construction is rather dated and a bit high priced. Additional modules are ridiculously priced that could be incorporated into the basic unit such as the use of a door chime
    MARIO -- granby, QC   11/21/2011
    I am very happy with this product
