What’s included with the kit?

The kit ships with the UT-2500 (transmitter) and the DCR-2500 (receiver).

UT-2500 Universal Transmitter:

The UT-2500 is the transmitter included with this kit and may be used as a wireless push button, and also a wireless door/window contact, and is also outdoor rated.   The UT-2500 is powered by a 3-volt lithium ion battery which comes included in the kit and should last up to 18 months without a battery change.  Please note, cold climates and more frequent use will dimish battery life.

The kit also features terminals for both a normally open (N/O) and normally closed (N/C).  These contacts allows you to integrate the device with other products that work with Normally Open and Normally Closed connections.  Not only will the device function as a  push button, it may also functions as a contact alarm to work in conjunction with your current system. This device will send a wireless signal over 2500 feet to your DCR-2500 receiver.   Whether you want to use the products as a doorbell button or a door window contact, the UT-2500 is a high powered transmitter designed for commercial applications.

The DCR-2500 Receiver:

The receiver is the standard receiving unit for the Dakota 2500 series. It is truly the “backbone” of a quality dakota 2500 series system. The receiver also features four “C” relays to wire any normally open N/O or normally closed N/C device to the receiver.  This allows you to integrate the device into a variety of other products.

The receiver also features one 12V DC output to add your favorite accessory to the system as well.   Do you need the chime sound to be louder?  Easy, hook an external speaker to the live 12VDC output.  Need a visual indicator?  Easy, wire an external strobe light to the live output.  Both the C relays and dc output can be set to activate for 1 second, 10 seconds, 60 seconds or 10 minutes.

The volume control knob on the receiver allows you to adjust the volume to suite your needs.

    The range of this unit was of critical importance to my application. It worked perfectly!! Easy to install and a reasonable price.

    Tried big box units and the range just didn’t come up to the advertised range. I needed at least 100 feet, preferably more for good measure. This unit did the job and more. Has some very nice extra features as well the big box store units lacked.

    Installed it for a retail client. Worked perfectly. The only thing I did not like about it was the button which slides into a holding plate which means someone could lift it out and steal it.

    I recently installed my new Long Range Door Chime for Business. It was easy to install. Once installed the signal went through a cinder block wall, up a flight of stairs and through a brick wall. Great product; it works!

    great range and functionality. works well through plaster and mesh walls. the system was actually really very easy to install, but the instructions manual could use a couple of photos for the novice. had to fiddle with the units for a few minutes to figure out how to open them.

    With the activities of the Holidays and lots of rain, I haven’t installed the door bell yet. I did read the instructions for setting it up and I think I will need to call you for assistance to set it up without damaging it. Hey, I’m 71 yrs. old and can be dangerous with any tool. Happy New year to all of you.

    We are very please with this door chime. It is a nice value and had nice chime selections as well as a nice volume control. IN addition when I called 1800 Doorbell I spoke with a Representative and he really was very helpful.

    This product is excellent. Our building is very long and narrow. It is built with cinder block and heavy metal doors. You can hear it clearly in the entire building. It saved us $2500 in paying to have one hard-wired in. Highly recommend it.

    We have a metal warehouse building and have had trouble finding a door chime for our receiving gate that would penetrate the building wall. This chime is the only unit that has worked and we have the bell button mounted about 100 feet from the chime.

    I am very impressed and happy with the LH 2500 and UT door alert system. We have 20,000 plus sq feet in our church with two main buildings. The new building is a two story metal building with a gymnasium attached. So I was worried about reaching the office with as it would need to go through both buildings. We put in two receivers and 6 transmitters and they work flawlessly! Yes, I would recommend it!

    Great Product, easy to install. Looks nice. High quality materials. Battery changes are easy.

    Perfect for our facility. 12K sq.ft and we were never where we needed to be when shipping/receiving carriers would arrive. We were skeptical about the volume of the chimes, but they are loud enough to hear even with industrial fans running. The range is fantastic. We use two units with two buttons. Each button rings both units so no matter where we are we know someone is at the door.

    We installed this system for two separate entries and they wring correspondingly in two separate locations. Both at least 100 feet away and through several walls. Works great. No complaints. I would buy it again.

    Product works great for a large office building. Installation was relatively easy. The chimes have adjustable volume. You can hear the chimes from a long ways away. We used the doorbell and door chime feature with the two receivers. Overall we are very pleased with the product.

    Works great . Both receivers are plenty loud . Range of the transmitter is fantastic . Longest run is about 200 ft through 2 brick block walls and lots of steel parts shelves. What we really like is the system is expandable. Just keep adding receivers. Parts people love it over the school bell it replaces.

    This is an outstanding product I would recommend to any business

    Purchased for a large distribution facility to let employees know when drivers have entered the cage for shipping/pickup. Tried off the shelf solution from big box stores with high hopes but higher failures!
    Purchased this unit after I saw one in use at another building and installed it the same day it arrived. The button is placed about 300′ from the receiver, and we haven’t missed a driver yet! Works as advertised. We are not signaling thru concrete, but there are many obstacles, such as machinery and racking that have not been an issue with this system. couldn’t be happier.
