Essential Info

When a visitor presses the button on the door intercom, the DoorBell Fon rings the phones in your home with a distinctive ring. Pick up the phone to converse with the door. 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. The system provides the necessary voltage to operate on its own.

Smarthome does not accept defective returns for this product. You will need to contact the Manufacturer (or Supplier) directly for all warranty issues.

    This system is also available in Ivory.

    Expand your intercom system with these optional accessories:

    Electric Lock Controller (#5070EL)
    Add this optional lock controller and an electric door strike and power supply and you can unlock the door from the phone by pressing "*".

    We recommend the following doorstrikes:
    Electric Doorstrike 8-16VAC (#5190)
    16VAC Electric Doorstrike for Schlage Locks (#5190S)
    12VDC Electric Doorstrike for Schlage Locks (#5190S12)

    A seperate power supply is required when using a doorstrike. See the doorstrike page for a recommended power supply.

    Doorchime Interface Module (#5070CI)
    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 (#5070R)
    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.

    Extra White Intercom (#5070DSW)
    For applications where you have multiple entryways, purchase an additional intercom. Also available in Ivory and Brass.

    Intercom Awning Single Gang (#5070A)
    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.

    Simple intuitive installation and operation. Works as advertised.
    JOSEPH -- leesburg, VA   7/4/2012
    This is my second purchase of the Doorbell Fon. Unfortunately, my first was hit by lightening... We liked it so much, we bought another. Simple to install... recommend the ring extender. It works fantastic with any standard phone answering machine. Unique ring tells you it's the door vs. an incoming call. Great device! Get one!
    FRITZ -- delray beach, FL   3/22/2012
    The item arrived here in time as expected and in perfect condition.
    STEVE -- los angeles, CA   3/18/2012
    great product, however the unit has from time to time some echos and squealing when you ring the door bell and before you answer. factory provided a replacement quickly. I would buy again.
    JAMES -- waddington, NY   10/13/2011
    Does all it is supposed to do. Volume is load and clear.
    TONY -- walnut, CA   8/28/2011

    This is our second DoorBell Fon. The first one lasted 14 years! Probably would have lasted longer if the weather hadn't damaged it. We are in an area that can get a lot of blowing rain. The unit is very easy to use with our phones and helpful in a large house because it was impossible to hear the regular doorbell. We can also use the intercom to answer the door if it is a delivery person just wanting to leave a package. It would be very good for someone that is disabled or lving alone.

    Product worked as it should. However, the door bell will not allow quest internet to work through the phone lines. Had to take the door bell out. Now what do i do with it?
    JEAN -- montreal, QC   7/31/2010
    I have installed several of these units, great money maker for instsllers. Clear voice, many practical options. Looks great and solid construction .
    LINDA -- weston, FL   3/2/2010
    Doorbell was easy to install and it works great! This is the second home that I installed it in and the directions were easy to follow and it looks good. I would recomend this to anyone looking for an integrated solution for their doorbell.
    WILLIAM -- madison, WI   2/27/2010
    We love it now that we finally have it installed, but it took weeks to get to that point. It's not nearly as easy to install as some say, but that might have been due to a couple of relatively unusual factors for us. First of all, we have DSL, which means we need to ensure that we're putting the controller ahead of the phones, not the computer. That calls for ensuring that the two are not using the same phone line. Second, the phone wiring in this house was in two, separate circuits, with one being the original and serving most of the house, and the second done by a previous owner. We were working forever to make this unit work with the latter, which is much more accessible, when the phones we wanted to use for door answering were on the former. Hours and hours of work were expended with the interior wiring, switching polarities and everything, until it dawned on us that we weren't even using the right circuit. It was literally nightmare time. Customer service was of minimal value. If you don't intimately know your phone system or how phones work, get an installer or prepare to spend tons of hours figuring it out with minimal instructions. But with the first answer to a door knock with our phone, we loved it all the same.
    NORMA -- oneill, NE   12/12/2009
    This doorbell answering unit is everything I needed to stop "running" for the door in a walker! Installation was beyond me, but my brother and a handyman made it happen.
    CINDIE -- saint petersburg, FL   12/1/2009
    Product as advertised; smooth transaction

    After my father passed away in July 09 my mother was in the house alone most of the time. She is not that mobile so I was looking into intercoms for the door so she could answer it from whereever she was. At first I thought of a wireless intercom but that would mean she would have to be near the inside box. Then I came across the Fon Door System. It is perfect for her since it rings all the phones in the house with a special ring so she knows it is someone at the door. This really works well for UPS or FedEx who won't leave a package w/o a signature. Many times she wouldn't hear the bell since it was so far away and she would find the note on the door that they tried to deliver a package. Now she can talk to them even if she is in the back yard from her portable phone. It works really well. Hopefully it will last a long time.
    BARBARA -- cincinnati, OH   5/24/2009
    This system is wonderful! The only complaint I have is that it comes with only one doorbell and I have a front and back door. I'll have to check to see if I can get a 2nd doorbell to work with it I will also buy another set for my business- it only has one entry door and I know my staff will love it also.
    RAYMOND M. -- savannah, GA   3/12/2009
    Great product!! This is a replacement for one that finally wore out after six years.
    JOHN -- bradenton, FL   2/11/2009
    This system is excellent! We put on an addition to our home and were unable to hear the doorbell from this addition. This system answered all our prayers. By instaling one at each door, we are now able to respond quickly to anyone who rings simply by picking up any phone in the house and speaking directly to the person at the door. I would highly recommend this system to anyone. One word of caution, however. When it is installed (as in our home) where cable TV, internet and telephone all come through the same line, the system must be installed in the same fashion as a burglar alarm, on the hardwire phone line just coming into the house. Our electricians had a little difficulty in working with the cable folks on this part, but it finally works and is perfect. Another feature is that it only causes the phones to sound their unique rings three times per button push, thus NOT triggering the answering machine. Great system, good solution for our particular problem
    ANTHONY P -- granite city, IL   7/7/2008
    The Doorbell Fon is a very good value for the price. The install was very simple as stated. It works great for what it is. However I wish the casing and button looked better. Overall it is a good product!
    THOMAS -- ormond beach, FL   5/30/2008
    Cool product!
