Finally, Long Range LOUD Warehouse Doorbell Kits For Larger Warehouses and Shops

When you need a doorbell system for your warehouses you have 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.

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.

Types of Bells or Sirens you can wire to this kit:

Each kit comes with a bundle of 15 feet, 2-lead 18AWG wire used to connect the bell or accessory below to the live 12v output on the receiver.  Learn more about each one of the bell accessories by clicking the link to the product.  Scroll down the page to see how to wire the unit.

The receiver in this kit has 4 zones to which you will pair a transmitter/sensor, with each zone playing a distinct sound. In this kit, you will also select an external accessory (FIREBELL, SIREN, CHROME BELL.MINI STROBE-SIREN) that you can add to a particular zone to increase the sound.  In addition you can select strobes or other external sound devices to add to other zones, using the 12V DC output.

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 would 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).
