Push Button 1 is programmed to Zone 1 on Receivers A, B, C and D (each of the four offices have their own receiver).  When someone presses push button #1,  it will trigger receivers A, B, C, and D to play the "Ding-Dong" sound.  So each office with their own receiver will hear "Ding-Dong" and know it is for the front door.

Push Button 2 is programmed to Zone 2 on Receivers A, B, C and D (each of the four offices have their own receiver).  When someone presses push button #2, it will trigger receivers A, B, C, and D to play the "Westminster" sound.  So each office with their own receiver will hear "Westminster" and know it is for the back door (push button #2).

Push Button 3 is programmed to Zone 3 on Receivers A, B, C and D (each of the four offices have their own receiver).  When someone presses push button #3,  it will trigger receivers A, B, C, and D to play the "Car Horn" sound.  So each office with their own receiver will hear "Car Horn sound" and know it is for side door 1 (push button #3).

Push Button 4 is programmed to Zone 4 on Receivers A, B, C and D (each of the four offices have their own receiver).  When someone presses push button #4,  it will trigger receivers A, B, C, and D to play the "Siren" sound.  So each office with their own receiver will hear "Siren sound" and know it is for side door 2 (push button #4).

Yes, we have many wireless doorbell and wireless notification systems that work well for the hard of hearing. These products will also work well for loud environments, such as workshops, where it may be hard to hear a normal door chime. In most cases these products will feature an alternative way to notify the user, such as a visual notification. For example, the WC180 is a flashing door chime for the hard of hearing. It's a wireless chime with a strobe light that features a flashing strobe light that is bright and easy to see.

Removing batteries or unplugging the transformer from the LRA-DCRX will not delete any programming.

This applies to the following ERA transmitters (ERA-DSTX, ERA-UTX, ERA-PIR)

-The ERA-DCRX (receiver) has four zone indicator lights that blink when triggered.

-When the battery is low in a transmitter paired to a corresponding zone, the zone indicator LED for that light will blink for 10 minutes when that zone is triggered.

-When the battery is low in a transmitter paired to a corresponding zone, the melody for that zone will play twice (normally the melody will play only one time).

For the ERA-PIR-SPK:  when the battery is low, the melody will play twice, instead of once.

How to Connect An External Device to the C-Form Relay on the ERA-DCRX

*Please note, in most cases it is sufficient to use the 12V DC outputs to connect an external device to the systemFor these instructions on this process, click here.

Each ERA-DCRX receiver has 1 x C-form relay for integrating and connecting external devices.  Unlike the 12V DC outputs (1 per zone) on the receiver, the C-Form relay DOES NOT supply power to the external device you are connecting to it.

Why use the C-Form relay?

The C-Form relay offers advantages and flexibility the 12V DC outputs do not offer.  For example, with the 12VDC output, the device you are powering has to be rated for 12V or less.  In addition, the external device you are connecting has to have a max current below 400mA.  This is not the case with the C-Form relay as it does not supply the power, but rather functions more like a switch.

Another advantage of the relay is that it's not limited to one zone.  There are dip-switches on the ERA-DCRX that allows you to associate the device on the C-Form relay with any combination of the four zones.  Let's say, for example, you have to push buttons, one for zone one, and another for zone two.  You might want to put a different colored strobe light on each of these zones.  Red on zone one and blue on zone two.  Push button A triggers the zone 1 melody and the red strobe, and push button B triggers the zone 2 melody and the blue strobe. You like the fact that the strobes provide a good visual notification, but want something really loud.  Using the C-Form relay, you add a loud siren or firebell to also trigger when one (or both) of the push buttons are pressed.

How to connect an external device to the C-Form Relay?

In this example, we are going to connect a 12V DC firebell to the relay and make the assumption you have a push button programmed to zone one (1) and another push button programmed to zone two (2).

1) Make sure plug-in transformer is NOT plugged in and ERA-DCRX receiver is NOT plugged in.

2) Flip dip switches 1 & 2 up, 3 &4 down.  This setting associates the C-Form relay with zones 1 and 2.

3) Set duration time.  This will determine how long the external device will turn on.

4) Connect black wire from firebell to the "NO" terminal screw on section labeled "relay."

5) Connect red wire from firebell to left terminal screw on plug-in transformer.

6) Use a wire to connect right terminal screw on the plugin transformer (ignore the center screw on transformer) to the "COM" terminal screw on the ERA-DCRX output section labeled relay.

7) Plug everything back in and start using!

Using the C-Form Relay on the ERA-DCRX
Using the C-Form Relay on the ERA-DCRX

The ERA-DCRX is a four (4) zone receiver meaning each zone will play a distinct sound.  You can program / pair as many transmitters (such as a push button) to a zone as you want, but all the transmitters in that zone will play the melody selected for that zone.

For example, zone 1 may be set to play the "ding-dong" sound.  When any transmitter paired to the zone is triggered, the receiver will play the "ding-dong" sound.  In this example, I have a push button on the front door paired to zone 1.

For zone 2, I want to program a push button for the back door.  When programming, I set that zone to play the Westminster  Chime.  When that push button is triggered, the receiver will play the Westminster Chime.

This enables you to distinguish a visitor at the front door versus the back door.

Up to 4 transmitters can be paired with a single receiver. However, since there are only 3 different chime tunes on the receiver, it is suggested to pair up to 3 transmitters by selecting different melodies for each transmitter.

The only real limitation with the ERA series of products are the number of zones.  As mentioned in a previous FAQ article, you can pair as many transmitters to a specific zone as you want.

There's not a limit to the number of receivers you can have in your system.  Whether you have 1, 2, or 4 different transmitters, you can have as many receivers as you want and can spread them throughout your warehouse, store or office space.

This type of configuration allows you to distribute the sound throughout your facility.  You may, for example, play a receiver in the warehouse and turn the volume up to its maximum setting.  However, because you might keep your door shut in your office, you may want to put your own ERA-DCRX receiver in the office and turn the volume down--or even mute it.

A) If you have a wired doorbell system, the Extend-A-Chime is just what you need. It is available as a kit, the LRA-EX1000. The kit works like this:  a small, battery powered transmitter is wired into your existing wired door chime.  When a visitor presses the wired push button on your door, you doorbell rings as usual...in addition to that, the small transmitter generates a signal and trigger the receiver that comes in the kit to play a chime sound. The Extend-A-Chime will allow you to easily increase the range of your current doorbell or door chime system so you will be able to hear it when you are out on your back deck. If you have a wireless doorbell system, you will need to purchase a compatible receiver for your system. Manufacturer's vary on how you determine compatibility. If it is a brand we sell, give us a call and we would be happy to help.
