Question: Can it be installed on metal door frame? (Some wireless chimes do not work properly on metal). Also, does it work with additional receiver?
Document: In the endless search for a wireless doorbell we bough this one based on the positive reviews - (it was also our 3rd attempt at buying a wireless doorbell) but unfortunately it only worked maybe 5 times? Then stopped working all together. Tried new batteries, moving the clicker closer to the receiver...nada.
When it works this is fine. Problem is that it decided not to work on a random basis and you have to &#34;Reset&#34; it so that it actually chimes when someone presses the bell. Then after a year it decided not to work at all for no reason. Lights flash to show that the signal is being recieved but no chime. I paid for what I thought would be a good wireless door bell and it has been a nightmare of missed deliveries and upset visitors.
Our office is in a commercial office building and has a ground level reception area and a concrete basement section well below reception, with several winding stair levels between. Wireless phones won't even work between levels. Needed a long range door chime and bot this chime and the unit to have it activate when upper level door opens. Works perfectly! Well packaged, intelligently designed. Takes a bit to get thru the programming, but instructions are accurate. Sixteen different chimes, with high volume if needed.
We got to thinking about how to solve multiple problems with one solution. You see, we recently installed an airlock on the front door of our rambling country ranch home as part of an energy efficiency retrofit. This made the existing doorbell inaccessible to visitors which was in need of solution. We also needed a better way to coordinate as family and to wake our sons in the morning.After looking at dozens of options, we bought the Dakota Alert and several extra remotes.
That is a nice feature, as without any hearing aids, there is no sound for me. If the aids are in, I can hear faintly the programmed "chimes" alert but the light gets my attention.My order also included an extra doorbell from another vendor and both arrived very promptly. I have one at the front door and one atThe back. No longer do my visitors have to stand at the door stoop and text me that they have arrived!
I needed a door bell for my 92 year old mother so she could hear someone at the door when she was on her computer sending out jokes to friends and family ! I tried several others but none had enough range to penetrate her metal front door and reach the back of her condo. This one did the trick. A bonus is that the ringer is adjustable and it also flashes so its hard to ignore. Good product.
I bought this unit to install for a client who needed a side door to have a bell. Since the day it was installed, this thing has not worked properly for more than two weeks straight. The first problem encountered was the white light flashing during the night, that woke my clients. Turns out, the new top of the line Energizer Alkaline batteries I installed were low.
The DC-1000 Did really well in straight line application . I am putting it in a large shop . I put in two buttons and two receivers and put them on two doors . I put it on two of the four zones . Both receivers ring , AWESOME . The button that wasn't a straight line , also had to go through two metal doors . I made a longer antenna and ran it inside the first door . Worked great !! Like this product will probably buy more for our other locations .
I like these units better than the Honeywells. They are more versatile in that you can use them with up to four different door buttons in four zones, and have as many chimes as you want. The volume is plenty loud enough (the lowest setting is almost too loud!). Clearly meant for an industrial setting, which is good. Small chance you will miss someone at your door. Configuring additional buttons is a piece of cake. And the range is superb.
I would not recommend this brand or product. I purchased right before Christmas vacation and installed the ringer. Within a few days I had to re sync the ringer to the bell because it wasn't working. Then came back from vacation and tried it out and it didn't work. Had to re sync. It will work for a day then stop. It's pretty important to have a bell that RINGS EVERY TIME someone is at the door and this just does NOT do the job.
