I bought several of 5 unit ones and 3 unit ones but one of the 3 unit ones interferes with a 5 unit one. Is there a way to change the frequency?

I was not able to change the frequency and they always seem to interfere with one another.

Yes you can. You can set the receivers to be on the same frequency. You can do that with any set. More importantly, stay away from this unit. It sucks. We had to replace it within 5 months of moving our twins in their room. And we should have replaced it sooner, we just didn't want to admit it sucked as soon as the problems started. Crackling, popping, mixed in with blasts of static that could last for 30 seconds to 10 minutes. Fun when it happened at 3 am! Stay away from this!

not possible with mine, it seems to be set at one frequency. I would like to know that frequency myself.

I also bought 3 and they are all on different frequencies (don't know the range). At this price, buy one and try it.

With the two I own, no. I suspected not, as there is no obvious way to adjust the send or receive frequencies. In most cases where multiple units are in use it would probably be necessary for each to act independently. Theoretically it could be possible to pair two or more sensors to a receiver during manufactured rather like multiple remote keys for a car, but I doubt if this would be done.

You should be ok, there are dip switches that let you set each one to different frequency, i have 2 and they don't interfere. Actually because of the remote's 2 sets of controls, i can control both switches from one remote. But you don't have to set it up that way.

You need to ask the question to the mfg. If they are the same frequency, they might interfere with one another depending on the distance and range of each..If they are DIFFERENT frequencies they will NOT.

It is fine to have them all in the same frequency band. I have 4 running in the same band with no issues.

I've used about a dozen of these devices and no two were on the same frequency. I think your using two or more in a close proximity would be fine. Each device will work only from it's own remote. The chances of you getting two sets on the same frequency would be very rare in my opinion.

I believe they all sound off with a verbal alert as to the unit that has detected a problem. I don,t think you can switch the frequency.

The directions on the package say you can have up to 3 however I have 3 and two of them are the same frequency which makes one of them useless. I submitted a question to the manufacturer that was listed on the product but did not get an answer. I couldn't find a place on the product page at Amazon to ask a question. Will probably have to return one of them.

Yes you can put multiple unit in same system as long as you keep the frequency/channel setting same on all unit.

I believe there is no way to change the RF frequency so that each remote operates on a different frequency. Here are two things to try:1 Adjust the antenna on the powerblaster or maybe even remove it so it only operates in limited distance. Call Universal and ask for tech support 914 835-4484.

No - they only sell these in the one frequency too so you can not have 2 running at the same time.

I perched 2 sets so I could have 1 push button activate 2 receivers at the same time. Apparently, my sets have 2 different frequencies. I believe the manufacture randomly sets the doorbells to have different frequencies. I was unlucky with my order and you by chance did not receive what you wanted. I suggest you return one set and ask for a replacement. The chance of you receiving a matching frequency is very unlikely.

There should be a set of dip switches on the receiver and inside the battery door of remote they must match . By turning on and off different ones of these switches changes the frequencies . Hope this helps

Hi, I'm not the seller of the product but I did purchase the unit awhile back and can answer the portion of the question I know the answer for. The paperwork that came with the unit stated it was available in three different frequency channels so multiple units can be used in the same location to control different devices. As for being able to choose the specific channel, I am unsure if that is an option. I know when I ordered mine through Amazon, it did not give me that option but maybe by contacting the seller before it ships. One point I wanted to make you aware of, to help you avoid any potential issues like I encountered, and that is to save the original packaging for at least a couple/few weeks. I had one of these units years ago and it worked perfectly for many years however, I wasn't so lucky on the unit I ordered a few months ago. I plugged the item in and it worked fine so not expecting any issues I went ahead and threw out all of the packaging. The item worked fine for a couple of days, maybe a total of 3x switching on/off, but stopped working after that. I've tried batteries and all troubleshooting steps in the instructions but it no longer works and I was unable to return w/o the packaging. Anyway, just wanted to let you know my experience which I assume or at least hope that is not a typical matter, especially since my prior unit worked so well for many years. Hope this helps. Best Regards
