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

Prior to 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 often times, 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 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 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.

Service and quality products

I'm very satisfied with my purchase which includes three receivers, two doorbells, a driveway sensor and a strobe light. No more pesky UPS trucks sneaking up on see.
I had purchased a Honeywell doorbell/chime from Lowe's a while back. While less money it didn't function well. The doorbells had to be pressed and held to operate and then there was only one chime. My new setup is instantly responsive when the doorbell is pressed, the driveway sensor works flawlessly and its sensing distance can be easily controlled internally so it's not bothered by vehicles on a nearby road. I purchased the devises with a much greater wi fi range than needed but I don't regret that at all. So far a flawless operation with different chimes set for each door and the driveway. Great customer service too. Call early morning to get Marilee, she's very knowledgeable and super courteous.

Great alarm system!

So glad we bought this driveway alarm. I now have peace of mind knowing we can monitor what is going on our property.

Better than I thought possible

I have a farm with two long driveways coming from the north and one from the south. I initially purchased one receiver and two transmitters just to test their effectiveness. I will be ordering two more receivers and at least six more transmitters to place in my tool shop and barn as intruder alarms. Their range is amazing and the different tones will alert us as to which driveway or building has been activated. I will also place transmitters on my front and rear porches to alert me when someone approaches either entrance. Fast and easy to install, conceal and operate. Highly recommend.
