Our customers have asked for a product like this for a while and we have finally delivered.  They have asked for a doorbell extender kit with flashing strobe receiver….The LRA-EX1000S is a kit that allows homeowners to extend the listening range of their current wired doorbell.  Do you have trouble hearing the wired doorbell in your home? Do you have areas in your home where  you can’t hear your doorbell, such as the basement or an upstairs bedroom?

This kit features a wireless doorbell transmitter that easily wires into your existing wired doorbell, and a plugin receiver.    Simply connect the transmitter to your wired doorbell (following the included instructions), plug in the flashing strobe receiver, pair the units together, and now you have effectively increased the sound of your current wired doorbell.  Now, when a visitor pushes the wired doorbell push button outside your home, your wired doorbell will work as normal.  Simultaneously, the wireless transmitter that was wired into the doorbell (located inside your home) will send a wireless radio signal to the plug-in receiver.  Depending on the operating mode the receiver is set to, it will flash the strobe, play a melody, or both.

The kit ships with one plugin receiver, but it is easy to add receivers in other rooms.  The LRA-DCRXS is the plug-in receiver that ships with this kit and is available to purchase separately as an add-on unit to expand it to other rooms.  For example, you might plug-in a receiver into your living room, and also purchase add-ons to put a receiver in the kitchen , upstairs bedroom, basement, garage, etc.    Not only is the LRA-DCRXS available, there are a series of other transmitters (motion sensor, door contacts, push buttons, etc.) and two other receivers  like the LRA-DCRX Multi-Zone Receiver and the LRA-VPRX Portable Receiver that are all compatible with one another.

The transmitter included in this kit wires into the existing wired doorbell in your home.  It is compatible with wired chimes that play a “ding” or “ding-dong” sound and is NOT compatible with video doorbells and intercom systems.  The transmitter is easy to install using the included instructions.  The transmitter works with up to two doors.  For example, your existing wired doorbell may play “ding-dong” for the front door and “dong” for the back door.  The transmitter extender may be setup to play one melody when the front door button is pressed, and a different melody when the back doorbell push button is pressed.  If your existing wired doorbell is only wired for the front door, that’s okay as well.

These are long range products that ensure they work in most environments.  Many people have negative experiences with wireless doorbell products, and that’s because the wireless range (from transmitter to receivers) for products purchased at hardware stores, tends to be 150 ft. max.  These are line of sight numbers and any building materials such as walls, doors, etc. will reduce the transmission range.  For example, a brick wall will reduce the wireless signal by 60%-70%, and each interior wall will reduce the signal by another 30%-40%.  Doing the math, you can easily see why our LRA products, with a 1,000 ft. range, have a dramatic improvement over a wireless product with a 150 ft. range.

Kit Features:

  • Kit ships with 1 x LRA-DCRXS Plugin Chime Receiver & 1 x LRA-EXTX Doorbell Extender Transmitter.
  • There is no limit to the number of LRA series receivers (LRA-DCRXS, LRA-DCRX, LRA-VPRX) each transmitter may be paired with.  For example, the LRA-EXTX extender may be paired with 5 different plug-in receivers you have placed throughout your home.
  • The wireless range from the transmitter to the receiver is up to 1,000 ft. line-of-sight.  Environmental and building materials will reduce the wireless range.

works, but came with dead battery

I like it. I ordered an extra receiver. However, the transmitter came with a dead battery and I had to purchase new batteries (waiting 2 wks) before I could actually get this installed and working.
Now it works fine, I have a different chime for the front and back door and the light on both receivers flashes with the chime (receivers placed on upper and lower level of the house)

Strobe doorbell for deaf daughter

Easy to install and link to current doorbell. Strobe plug-in easy to relocate if needed.

Does not work with video doorbell

I installed the wireless doorbell as per the instructions. I rang the door bell to and it worked. Then it started ringing for no reason. I discovered that every time the video camera picked up motion it would activate the doorbell. I am returning it for a full refund


Very good company. They do try to make customer happy


Instructions were a little hard to follow , they need to be up dated to reflect the current model. Once installed it works great
