WDK-ERA-KIT Commercial Grade Wireless Doorbell Kit with Siren Sounding Alerts

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. There were only a couple of options. One is to wire a doorbell or two, which is cumbersome, inconvenient and time consuming. However, most wireless systems 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 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 signal up to 4,000 ft. away from 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 an excellent kit for businesses.

The WDK-ERA-KIT series features the ERA-UTDCR and an additional bell (multiple choices available) to 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, each with a live 12VDC output. Zone 1, in this video, is paired with a long-range wireless magnetic door contact that is triggered when the door is opened.

Types of Accessories (Fire Alarm Bells, Strobe, Sirens) you can wire to this kit:

The image below shows how the strobe/siren (unit on the left) is wired to the ERA-DCRX receiver. 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.

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 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 four 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 (FIRE ALARM BELL, SIREN, CHROME BELL.MINI STROBE-SIREN) to add to a particular zone to increase the sound. In addition, you can select strobes or other external sound devices to add to different zones using the 12V DC output.

Please note. These are the sounds the actual receiver plays. They can be turned down, muted, or played with the add-on accessory chosen in the kit.

Available Accessories

These accessories hook up to the live 12V DC outputs on the back of the ERA-DCRX desktop receiver. For instructions on how to wire the 12V DC devices below to the ERA-DCRX 12V DC outputs, please see the instructions here.

How do these accessories connect to the receiver?

On the back of the receiver are 4 x 12V DC outputs. You connect the supplied wire from the accessory to the back of the receiver using the supplied wire. When the sensor transmits a signal, the receiver will play the associated chime sound and send a 12V DC 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)

The receiver also features a 1 x C-FORM relay. The time setting for the relay will be the same as specified for the 12V DC outputs. The C-Form relay may be set to any combination of zones. You can set the relay when zone one 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.
