  1. Open the cover of the receiver
  2. Hold down the "zone selector" button (the left button) for approximately 3 seconds until zone 1 starts to flash.  Stop pressing the button.  If you are deleting memory from zone 1, move to step 3.
  3. Push the left button again to scroll to the zone where you want to delete memory.  The zone number will flash.
  4. Simultaneously, hold down the zone selector button (on the left) and the melody button (on the right) for approximately 3-5 seconds until you hear a short tone sound.   The short tone sound means the memory has been deleted in that zone.

  • Once a transmitter / sensor is programmed to a zone on a LRA series receiver, a new transmitter / sensor cannot be added to that zone until the memory of that zone is deleted.For example, if you have previously programmed a LRA-PBTX push button to Zone 1 on your receiver and after a few years of use you want to replace the push button.  Prior to programming your new push button to the receiver, you must delete the old transmitter that is locked into Zone 1 memory.The instructions below illustrate how to delete the zone memory from the LRA-DCRX and LRA-DCRXA memroy.  The process for the LRA-VPRX is slightly different, but the basic concept is the same.  To delete memory from the LRA-DCRXS Plug-in Strobe Receiver, click here.
    • Make sure you are deleting the right zone. If the transmitter/sensor is programmed to zone I, for example, the Roman Numeral for zone I will flash when triggered.
    • Enter programming mode my holding down the zone selector button for approximately three (3) seconds.  The strobe will flash and the icon for Zone I should start flashing.Programming the LRA-DCRX Receiver
    • Once the strobe flashing and you are in programming mode, stop pressing the zone selector button.
    • If you would like to delete the memory in zone one, skip to the next step.  If you want to delete the memory from another zone, press the zone selector button to scroll to the zone you wish to delete.
    • Once you are at the right zone, hold down the zone selector button AND the melody button (at the same time) for approximately five (5) seconds. You will hear a short tone sound. This zone has been deleted.
    • Next, press the program button to skip through the other zones.
    • Once you pass zone IV , the zone lights will stop flashing, signaling it is out of pairing/programming mode.

Below are brief instructions on how to connect a 12V DC device, such as a strobe light, siren, buzzer, etc. to a zone on the ERA-DCRX receiver.

 

1. Unplug the receiver.

2. Separate top receiver case from bottom receiver case.

3. Locate terminal block (see image below) located on the bottom of the pc board.

4. Loosen screws for the zone(s) that you are connecting a device to.

5. Wire the external 12V DC into the terminal connection blocks that
corresponds to the respective zone. For example, if a push button is
paired to zone 1, and you want a strobe to flash for zone 1, wire the
strobe into the terminal block for zone 1.

6. Observe polarity when necessary. For example, for a strobe light,
ensure you are connecting the positive wire on the strobe to the positive
terminal on the receiver.
7. Re-tighten screws on terminal block.
8. Adjust output duration as needed (see image below)

9. Snap cover back together.
10. Plug in receiver.In the image below, there are two different 12V DC devices connected, one per zone.

With a range of up to 4,000 ft., there are extreme situations where the ERA-UTX transmitter (push button) may not connect with your ERA-DCRX wireless plugin receivers.  Thick concrete, steel doors, or other factors may reduce the wireless signal so much that you cannot achieve the distance you need.

A solution to the problem can be achieved using the normally open relay in the ERA-UTX.  The illustration below shows an example of how a wired push button is wired to the ERA-UTX wireless transmitter.

When the wired push button is pressed, it triggers the wireless transmitter to the wireless receiver.  By placing the wired button outside and placing the wireless transmitter inside, the number of barriers the radio signal has to go through is dramatically reduced, thus improving the wireless signal and range from transmitter to receiver.

  • This same scenario works with a wired magnetic door contact.
  • Polarity is not important.
  • Use a non-lighted wired push button only.  A lighted button will drain the battery from the wireless transmitter.
  • Use the normally open relay on the transmitter.  They are not labeled on the unit itself, wire it as in the image below.

Locate the two buttons located on the side of the receiver.  The program button is a solid dot and the melody selector button has a musical note symbol next to it.

Hold down the programming button for approximately 3 seconds until you see a solid red LED inside the strobe light lens.

Let go of the programming button--the red LED should stay on.

Simultaneously, hold down the programming and melody selector buttons together for approximately 5 seconds until you hear a short tone sound.

Let go of the buttons.  You should now see the red LED flashing rapidly.

A flashing red LED denotes programming mode.

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.

-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.
