Frequently Asked Questions About Wireless Chimes, Doorbell, & Entrance Alert Products

In most cases, if your LRA-DR1000 is not working correctly, it is because of one of three issues:


1) Photo sensor dip switch is set to night time mode only
2) Sensor/transmitter not paired with receiver correctly
3) Weak or dead batteries in sensor/transmitter

1) Photo Sensor Inside Driveway Sensor (outdoor unit) May Be Set to Nighttime Only Mode:

The LRA-DSTX transmitter/sensor has two operating modes, all-day mode and nighttime only mode. Often times, if the transmitter doesn't seem to be working, it is because the dip switch is set to nighttime mode only.

To check this setting, please take the top cover off the sensor/transmitter an orientate as in the picture.

Once you have the sensor oriented just like the photo, located the photocell dip switch which will be located directly under the "test" button.

For all-day operation, please ensure the switch is pushed all the way down. If you want nighttime only operation, make sure the switch is in the up position.

2) Transmitter is not Paired Correctly with the Receiver:

Watch this short video on Youtube we put together to help with programming the transmitter/sensor with the receiver

a) Push the program button on the receiver until you hear a short tone sound
b) Once you enter program mode, Zone 1 on the receiver will flash. If you want to pair your transmitter to Zone 1, move to step d). If you want to pair to a different zone, go to the next step.
c) Pushing the program button will move to the next zone. For example, when you enter program mode the receiver is in Zone 1. If you want to pair your receiver to Zone 2, pushing the program button again will move it to Zone 2.
d) Once you are in the Zone you want to program, push the melody selector button until you are the sounds you want the receiver to play when the transmitter/sensor is triggered.
e) Push the "test" button on the sensor (see picture above). You will hear two (2) short ton sounds, letting you know the sensor/transmitter is paired with the receiver.
f) If you want to program another transmitter/sensor to the receiver, go back to step c) above. If you are done programming, press the program button to scroll through all the zones. After you scroll past Zone 4, you are done.

3) Make Sure You Have Fresh Batteries:

Make sure you are using new, Alkaline batteries in both the transmitter and receiver.

  • If the model number DOES NOT end in "-L" (similar to the first image on the left) then please contact us by email or phone to ensure we ship you the compatible product.
  • If the model number on back of your product DOES end in "-L"(Similar to the image on the right) then proceed with your order without contacting us. 

-When I try to enter programming mode on the receiver, the red LED is not flashing, it is a solid red LED that does not flash:

This signifies that the two zones of the receiver are programmed/occupied by transmitters.

To program transmitters, you must delete the memory of the receiver.

To change a programmed melody on the LRA-DCRXS (plugin strobe receiver) you must erase the memory and reprogram.  During programming, you can select the melody you want for each transmitter.

Please note, the melody associated with a zone on the LRA-DCRX may be changed without deleting the memory.

Using the Relay on the LRA-DCRX to Connect External Device

LRA-DCRX-Receiver-Relay-500x417 The LRA-DCRX receiver features a relay that may be used to integrate and activate an external device.  For example, a strobe light, 12V DC output, or other devices may be configured to trigger when the relay on the receiver activates. Tips & Notes:
  • The unit WILL NOT supply power to the external device.  The external device must have a separate power supply.
  • The relay ONLY works with Zone 4 on the receiver.  For the relay to work, there must be a transmitter paired with Zone 4.LRA-DCRX-Relay-Diagram-500x282
  • The relay DOES NOT provide power.
  • The relay may be set to normally open or normally closed.
  • Ensure the relay is set to the "on" position.
  • Set the duration of output to 2 seconds or 5 seconds.
In this example we will wire a 12V DC siren to sound when the push button paired to Zone 4 is triggered. LRA-DCRX-Relay-Wiring-to-External-Device-Updated What you will need:
  • A LRA trasmitter (push button, door contact, etc.) paired to zone 4 of the LRA-DCRX receiver.
  • 12V DC siren
  • Extra wire (as needed)
  • External power device used to power the 12V DC siren.  In this example we are using a 16.5 VAC /40VA Class II plugin transformer.  Please make sure the power supply you use will supply the necessary power to the external device.
  1.  Ensure the power supply is unplugged.
  2. Wire one wire of the siren into one of the "normally open" connectors on back of the receiver (see image below).
  3. Wire the other wire of the siren to the plug-in transformer (see image below).
  4. Take a wire and connect one end into the other slot of the "normally open" relay.
  5. Take the other end of that same wire and connect it to the transformer (see image below).
  6. Plug in the transformer.  Ensure the receiver is powered on--test.

How to Change the Melody

The LRA-D1000S kit with th e LRA-PBTX and the LRA-DCRXS are will need to be programmed.

Once you've programmed a transmitter 

 The change this melody, please follow the video instructions below.

The WC180 has over 16K different transmission (privacy) codes.  When you pair the transmitter with the receiver, the unit will randomly select one of 16,0000 codes to pair.

Each of the four (4) zones on the ERA-DCRX receiver has a live 12V DC output.

These outputs enable you to connect an external device to the output to activate when that zone is triggered.

For example, let's say you operated a loud workshop and when loud machinery is turned on, it's hard to hear the receiver.  The live 12V DC outputs provides a couple of options.

One option is using a 12V DC LED Strobe Light and connect it to the output for a zone.  When a visitor arrives and presses the compatible push button, the ERA-UTX, not only does the paired receiver(s) play the chosen chime sound, the bright strobe light will provide a good visual indicator.

Safeguard Supply provides packaged kits that come with a strobe light (4 colors to choose from) along with "bellwire" (a bundle of 18AWG wire), as well as the push button and receiver in the WDK-ERA-STROBE.

Another option would be to connect a loud 105 dB rated siren to the 12V DC output.  When a visitor arrives, the chime plays, and the siren plays a very loud sound to alert you that a visitor has arrived.

Like the WDK-ERA-KIT, Safeguard Supply also has the WDK-ERA-KIT with options like a FIREBELL, SIREN, and Chrome Enclosed Buzzer to choose from.

Each zone has its own 12 V DC output.  That means you can mix and match 12V accessories, like a different strobe color for each zone, to help you better determine which push button or magnetic entrance alert was triggered.
