  • Amplifies a telephone ringer with an adjustable tone control switch (High/Low/Off)
  • Sends a strobe light notification when an incoming telephone call is received
  • Three AA batteries provide backup power

Essential Info

If you live or work in a loud environment, it's likely you have missed several calls because the sound of the ringer has been drowned out by ambient noise. The Amplified Telephone Ringer with Strobe Light Alert takes care of this problem so you'll be less likely to miss an important phone call in the future. This product features two types of alerts to help ensure you know when a call is coming in through an amplified ringer and a strobe light. The amplified ringer has an adjustable High/Low/Off setting, with the 'High' setting boosting your ringer up to 120dB when an incoming call is received. The strobe light will also flash when there is an incoming call, offering a visual indicator. The device simply installs between your existing telephone and the telephone jack and uses a plug-in adapter for power, included. As an added bonus, you can install three AA batteries, sold separately, to act as a backup power supply in the event of a power failure. This device will work on any standard landline telephone system and can even be used as a way to help the hearing impaired receive a phone call notification.

    Absolutely does what I needed it to do for my mother who is having trouble hearing these days. She hasn't missed a call since the Telephone Ringer with Strobe Light was installed!
    DIANE -- white stone, VA   2/28/2014
    So far so good!
    JONELL -- n kingstown, RI   1/13/2013
    great and a big help for a brother who is almost totally deaf.
    MICHAEL -- holts summit, MO   12/15/2012
    My mother has a severe hearing problem even with her hearing aides. We wanted a bell loud enough for her to hear even without her hearing aides. I tried an external ringer from a different store that was 95db and she was unable to hear that one very well. So we tried this one. I tried it on Thanksgiving day with the entire family standing around unaware that I was going to try it. They liked to have jumped out of their skin and Mom could even hear it... works well and the flashing light is a great addition as well.
    ELVIS -- magnolia, AR   10/14/2012
    Received product promptly and in good shape. Easy to use website. Would recommend to other customers. Product performs as expected
    DONALD -- leonardtown, MD   4/29/2012
    Easy to hook-up and ringer is loud enough to get your attention every time.
    MARY ANN -- paw paw, MI   3/9/2012
    It's just what Mom needed to be able to hear her phone! And it was so easy to install. Love it!
    WARREN -- asheboro, NC   10/21/2011
    Inexpensive but fills the need. Easy to connect.
    SCOTT -- belvidere, IL   10/3/2011
    Would highly recommend the amplified telephone ringer with strobe light. The ringer can be heard over a dust collection system and table saw running at the same time.
    JOSEPH -- laredo, TX   7/1/2011
    Does everything you said it would
    ROBERT -- seymour, TN   6/25/2011
    It does a good job.
    JOEL -- findlay, OH   5/2/2011
    The strobe light works well and it's the only phone signal I notice while wearing ear protection while working in the shop. I recommend this product.
    WARREN -- asheboro, NC   4/23/2011
    Pretty cool, an excellent deal for the price. Battery or AC power.
    GEORGE CASTILLO -- brownsville, TX   12/21/2010

    works great!
    DONALD -- guntersville, AL   2/7/2010
    I purchased two units for my mom who has difficulty hearing her phone. They worked great and now my mom hears her phone when it rings. Installation was a breeze and I would recomend the amplified telephone ringer and strobe alert for anyone who is hearing inpaired. I WOULD GIVE THIS UNIT A FIVE STAR RATING.
    D STROUD -- guntersville,AlC   12/31/2009
    Installation was a breeze. Ordered for my mother who has two hearing aides and still needed more ringer volume. With both the strobe and additional volume has helped tremendiously. In fact, I plan to order two more for other parts of her home.
