Finally, a Long Range Warehouse Chime with Loud Sound Designed for Large Warehouses & Business Spaces

Before the WDK-ERA-KIT, when you wanted a Long-Range Warehouse Chime with Loud Sound, it wasn’t easy to find them.  There were only a couple of options.  One is to wire a doorbell system or two, a wireless system.  You might have to count wired systems out because oftentimes, getting a wired doorbell push button outside is not feasible.  However, when you search for a quality wireless door chime, they simply don’t have the range necessary to power through the obstacles seen in warehouses (concrete, metal, etc.).  That is until we created the WDK-ERA Series of Wireless Door Chimes.

If you would rather have a kit with a visual notification, please see our Warehouse Doorbell Kit with a Strobe Light.  This is a Long Range Warehouse Doorbell with a Loud Sound
These products were specifically created for industrial, warehouse, shop, and office environments.  The “bones” of this kit is the ERA-UTDCR Long Range Doorbell Kit.  This kit features a wireless push button that can send a wireless signal up to 4,000 ft. away to the plugin receiver featured in the kit.  By itself, the receiver is loud at approximately 85 decibels.  In addition to this, you can purchase additional receivers and spread them throughout your facility to help distribute the sound.  By itself, this is a great kit for businesses.
The WDK-ERA-KIT series of products are kits that feature the ERA-UTDCR and an additional bell (multiple choices available) that will increase the sound output to 90-115 decibels.  To hear each add-on sound, please scroll down the page.

Like other products in the ERA series of products you can add more push buttons, door window contacts, or plug in chime receivers to augment your system.
Each ERA-DCRX receiver has four zones and each zone features a live 12VDC output.  Zone 1, in this video, is paired with a long range wireless magnetic door contact that triggered when the door was opened.

The image below shows an example of how the strobe/siren (unit on the left) is wired to the ERA-DCRX receiver.  The cover over the receiver (unit on right) is removed to show the wiring.  After installation, the cover should be snapped back onto the base unit.  In this example, the strobe is wired to the 12V DC output for zone one.  When this zone is triggered (by ERA-UTX, ERA-DSTX, or ERA-PIR) the chime will sound and the connect strobe/siren will trigger.

How to Wire the SS-PSIREN-W to the ERA-DCRX

How do these accessories connect to the receiver?

On the back of the receiver are 4 x 12V DC outputs.  Using the supplied wire, you  connect the wire from the accessory to the back of the receiver.   When the sensor transmits a signal the receiver will play the associated chime sound and send a 12V DC current to the connected device.   For example, if you have the 12V DC Chrome Buzzer connected to the receiver, when someone at the front door pushes the button, the receiver plays a chime sound and the chrome bell will go off for the set duration (5 seconds up to 2 minutes).

Wiring the 12V Output (one per zone)

ERA DCRX Wire 12VDC Device

The receiver also features 1 x C-FORM relay.  The time setting for the relay will be the same as set for the 12V DC outputs.  The C-Form relay may be set to any combinations of zones.  Meaning, you can set the relay when zone 1 triggers, or any other combination of zones.  It is important to note that the C-FORM relay DOES NOT supply power.  Below is an example wiring scenario using the C-FORM relay.

1 x ERA-PBDCR Commercial Door Chime Kit with Push Button

I've purchased several wireless door bells that supposedly work well and long distance they were all garbage. but when I got this one I put threw the test I set it up and literally walked 2 blocks away from my house and had my wife on the phone and pressed the push button bell this thing worked like a charm. I've had for a week now and each time is has worked great unlike the others bells that I bought only rang or worked randomly. I would definitely recommend this doorbell to family and friends

Great Products and fast shipping

Very good products. The wireless transmitter and receiver work and cover our entire house. My only disappointment is that there is a battery that must be replaced. It is too bad the electronic design can't tap the power from the transformer for the doorbell itself. Great product and great service.

c.B.S. (Weatherford, US)

Great products. We'll worth the small investment.

H.P. (Socorro, US)

The doorbell wireless push button and portable bell working great. The only setback the door sensor has to be within half inch of the button which makes it. non functional if the door is recessed from the jamb. Otherwise overall prity handy product
