UT-4000 Warehouse Door Contact or Doorbell Push Button with 5,000 ft. Range

The UT-4000 is a transmitter compatible with the Dakota Alert 4000 series of products and is the push-button transmitter in the LH-4000 warehouse doorbell kit.  This transmitter may be used as a long-range wireless push button or a door window contact.  As a long-range wireless warehouse doorbell push button, the unit will transmit a wireless signal when the push button is pressed by a visitor.  As a long-range wireless warehouse entrance alert, the unit will transmit when a door is opened.

Please note, that it IS NOT compatible with the Dakota Alert 2500 series or the ERA series by Safeguard Supply.

When the sensor is triggered (push button or contact), the unit will transmit a radio signal up to 5,000 ft. (line of sight) to the compatible plugin door chime receiver, the DCR-4000.   The transmitter may be mounted to an exterior wall next to the door as a push button or mounted on the door frame and door when used as the door magnetic contact in a wireless entrance alert system.

Will This Warehouse Push Button Work in My Warehouse?

Although all environments are different, I would make a bet this product would be one of the only wireless doorbell products available in the marketplace today that would work in almost every situation.  Why?  Because of the long-range transmission capability of this transmitter.  Most products available are designed for residential home usage, meaning the wireless range will top out at around 300 ft. - 1000 ft.  This may sound like an adequate distance, but the reality is that in most commercial environments, whether a large warehouse or smaller convenience store, or gas station, there's a significant amount of interference for wireless products through concrete, rebar, metal, etc.  For example, did you know a concrete wall could diminish a radio doorbell signal by almost 50%, and standard interior drywall by about 20%?  So every time this radio signal has to penetrate a wall, the signal is degraded.  This leads to an unreliable product.

How is this business-grade push button powered?

The push-button is powered by a long-life 3V lithium battery.  Within normal business operations, the battery should last 12-18 months before replacement.

Can you use more than one push button or door entry alert?

Yes.  You may use up to 12 different transmitters with this system, with each transmitter playing a different melody or tune on the receiver.  This allows you to easily distinguish between the door that triggered the alert.  Sound one for the front door, and sound two for the back door.  Like every product in the 4000 series, you can also add additional DCR-4000 plug-in receivers.
