Our 1800's masonry church had a doorbell transmitter that couldn't penetrate the massive walls and many chambers between the South Entrance and the Church Office. With this LRA-RPX 1000 Ft. Range Extender we are back in business

Safeguard Supply LRA-RPX 1000 Ft. Range Extender Battery Operated
*Wireless range is based on open-air testing. Walls, metal, masonry, and interference can reduce real-world performance. Learn more.
Note: This is only compatible with the “non-L” series of LRA products. For example, if your existing push button is LRA-PBTX-L or the receiver is LRA-DCRXA-L, this will not be compatible. Extend the range of your LRA wireless system by another 1000 feet. For an extended range, place this “repeater” between your transmitter and chime receiver. The receiver is battery-operated, and no setup or pairing is required.

LRA-D1000
Great for large homes and businesses that need to transmit over long distances, the LRA-D1000 has the power to penetrate walls that typical products cannot. A selector switch on the side of the door chime can be set to “flash,” “chime,” or “flash and chime.” Use with batteries or the optional power supply. An excellent choice for use in residential applications for the hard of hearing or in noisy, commercial environments. The perfect choice for homes of all sizes and mid-sized businesses.

LRA-DCRX-L
The LRA-DCRX is a wireless doorbell/door chime receiver compatible with the Safeguard Supply line of notification devices. This product will receive signals from up to four compatible long-range transmitters/sensors, featuring loud volume control and a bright strobe that adds a visual display. Use the push button, door contact, motion sensor, or driveway sensor.

LRA-PLUG
LRA-PLUG is a plug-in wall adapter for compatible LRA receivers. Use it when you want to power an LRA receiver from a wall outlet instead of relying on batteries alone.

LRA-RPX
Note: This is only compatible with the “non-L” series of LRA products. For example, if your existing push button is LRA-PBTX-L or the receiver is LRA-DCRXA-L, this will not be compatible. Extend the range of your LRA wireless system by another 1000 feet. For an extended range, place this “repeater” between your transmitter and chime receiver. The receiver is battery-operated, and no setup or pairing is required.

Buying notes
Is this the right fit?
- Good fit when
- Use this when you need to add, replace, or move the part that makes the sound, flashes, or provides the alert output.
- Look at another option when
- It will not create a new alert point by itself. Choose a compatible transmitter, such as a push button, door contact, PIR motion sensor, or driveway sensor, or choose a complete kit if you need both sides of the system.
- Range reality
- 1000 ft is the published open-air distance from a compatible transmitter to this receiver. The transmitter may be a push button, contact, PIR motion sensor, or driveway sensor. Walls, metal, masonry, vehicles, shelving, and dense trees can reduce that distance.
- Setup note
- Place the receiver where people need the alert, then pair it with the existing compatible transmitter. For large or divided spaces, test more than one receiver location.
The LRA-RPX is a relay/extender that can increase the range of your LRA wireless alert system up to an additional 1,000 ft. The LRA system has a line-of-site range of up to 1,000 ft. Environmental factors will cut down on this range, meaning in a real-world environment, wall materials, terrain, and other factors that cause interference will diminish the effective range of any wireless kit.
This product will add 1,000 ft. to the system by taking in the wireless signal, amplifying it, and sending it back out. Place the LRA-RPX between (preferably centrally located) the transmitter and the receiver. No, set up required; place the unit, and turn it on.
Indoor rated only!
Extend LRA Wireless Alert Range Between Transmitter and Receiver
The LRA-RPX range extender is used when an LRA wireless doorbell or alert signal needs help reaching the receiver. It is not a replacement receiver; it is a relay that listens for the original signal, boosts it, and sends it onward. This makes it useful for a long range wireless doorbell extender in larger homes, shops, offices, or outbuildings where walls and distance reduce performance.
Placement Tips
- Best location: place it between the transmitter and receiver, preferably near the middle of the signal path.
- Range planning: real-world range is affected by walls, terrain, metal, and other interference.
- Environment: this model is indoor rated only, so do not mount it outdoors without proper protection.
Buyer FAQ
Does it require programming? The existing copy notes no setup is required; place the unit and turn it on. When should I use it? Use it when an otherwise compatible LRA system works at shorter distances but becomes unreliable across the full property.

Works great. Gives me the coverage that I needed. Now I know which door to go to.
I explained my problem with the lady who answered my phone call. She she listened courteously and then suggested the device needed to correct my problem. She told me the price, took my payment method, and shipped it as promised. I received the part shortly afterward, anxiously installed it and “PRESTO”, my problem was solved!! Its nice to deal with someone who is knowledgeable and professional. I am a happy and satisfied customer. Bill ABSHER Marion, Illinois

Questions & Answers
Answers from our team for Safeguard Supply LRA-RPX 1000 Ft. Range Extender Battery Operated.
Can we have a series of LRA-RPX repeaters relay the doorbell signal? We are looking at replacing our dead doorbell system (strobes for hearing impaired) with a wireless system. We are a Deaf church in a 3 story Victorian house. There really is no line of sight. Social hall and kitchens on the 1st floor, offices on the 2nd floor, priests' bedrooms on the 3rd floor. All are deaf, so the strobe receivers are needed on all 3 floors. Can I place repeaters on the each stair landing so that the doorbell signal is handed-off to the 2nd and 3rd floors and their receivers?
Good morning. Due to the size of the area, we would recommend the ERA-DCKIT which has a a range of up to 4000 feet. Each of the ERA-RXPG receivers have a flashing strobe light and you can add on as many additional receivers as you would need. The ERA system is also compatible with up to 12 door transmitters. I have included the links below but please let us know if you have any other questions.
