Fosmon WaveLink Wireless Door Open Chime with 1 Receiver + 1 Door Sensor

We got this because we have a young adult child with brain injury who escapes out the back door when no one is looking, and also likes to go into the bathroom in the middle of the night and overflow the sink. After waking up to an inch of water on the bathroom floor, we decided we needed to take drastic action. Because our other daughter has autism, we couldn't use the alarms that beep or sound like a siren. We needed something more pleasant that would still get our attention in a sometimes noisy home. When I found this alarm that plays music, I thought it might work for us. This alarm arrived quickly, was simple to install, and works well for our family. We found two different songs to signal the back door and the bathroom door. There are enough different kinds of sounds that you are sure to find something palatable for your household. There are several different door bell chimes, a siren or barking dog (if you want to scare off burglars), and so many tunes we never made it through all of them. We just picked a couple that were acceptable to us. The receiver has 3 volume settings. We use the loudest one, and it is audible at least 3 rooms away, through plaster walls and doors. So, while it wasn't our primary reason for buying this alarm, we now have an additional security feature on our house. We live in an old house with plaster walls. The bathroom door is about 30 feet from the receiver, with several walls and heavy wooden doors in between. There is no problem with the signal being sent through these obstacles, even when all of the doors in between are closed. I recommend this alarm to any caregiver who needs something to let them know their loved one needs some supervision. It will change your life!

I purchased this last year because my toddler sleeps on the 2nd floor and we sleep on the 3rd floor and I needed peace of mind knowing I had an extra set "eyes and ears" on her while we are asleep. If I didn't hear her awake and moving around on the baby monitor, I wanted to know that this would for sure wake me if she decided to venture out of her room while I was asleep (heaven knows that sometimes even a light sleeper can fall into a deep sleep!). It works like a charm!! Installation was quick and easy! We installed it at the top of her door (so she would never be able to pull it off) with the double stick tape that was provided and it didn't quite work because the door frame is a little chunkier- but it was an easy fix . I had extra double stick tape left over from something else so I just doubled up on the tape and that lifted it enough to get it to meet./touch the sensor. We plugged in the sound receiver in our bedroom and chose one of the many chimes/songs and adjusted the volume (the loudest level is very loud!) and synced them without issue. You will need a 2nd person to help sync them if you are more than 5 seconds away from the door. I should also note that there is a blue light that blinks with the sound/song/beat which I think is a great feature for the hearing impaired. I am writing this review a little over a year after purchasing it because our receiver stopped working, but I emailed the company and they sent me a new one for free! There is a lifetime warranty on their product- how amazing is that?! The process was quick and easy, just a few emails explaining the problem, verifying my purchase on amazon (send them invoice from your "previous orders" and verifying address.) WOW- not many companies stand by their product like this and I was already pleased with our door chime, but this experience just took it to another level! Totally recommend this product for your adventurous toddler, secret mom power to 'mysteriously' appear when a kid opens a door, or business!

I just installed 2 of the alarms on my doors and they work great. I was concerned about the functionality given my molding frame around the doors and it works well on the curved molding but not on the elevated raised molding. I attached photos to demonstrate. The first 2 photos show my white back door with curved molding and the alarm mounted at an angle and it works without a problem. The 3rd photo is the front wood color door with a narrow trim before the molding begins and the sensor fit in that level area great. The 4th photo is my side door that had different molding that sits elevated from the door and thus I could not get a connection when the door was closed. The alarm would not work on that door setup. I can probably rig something to mount the door unit elevated about 1/4" or so which would help the 2 line up so it will eventually work, just not out of the box. Double sided tape on a small square of wood attached to the door and then putting the alarm on the wood block would work so all is not lost. Very happy with the ease of installation and they work as long as pointing towards each other even if off angle.

And it chimes when on loud setting loud enough to be heard 2 hollow-core doors away from the chime. So it's fine. But only as a chime. Not an alarm. Update 2023-06-30: 1) We have paired 2 sensors and, with a little fiddling, each elicits a different sound from the base unit. The font door elicits a Bing-Bong. The slider to the patio a Wah-Wah claxon. OK. Good. 2) We put the base station near the bedrooms on a timer. It gets power from Midnight to 6 AM only. Otherwise is unpowered hence silent. Settings are remembered. OK. Good. 3) But the sounds when triggered by the sensors only play once and then shut off. So if you don't wake up at the first instance of the sound from the base and as the claxon will shut off all by itself(!) then the perp can just walk right in. Bad. Very bad. It would be better that the claxon continued to sound until someone awakened, got up, called the cops, went to the base and, when safe, turned it off. Or the claxon could time out after 1 hour - in case we were away on vacation. Adding more units won't help because the sounds - bing-bong or wah-wah - stop on their own within a few seconds. Just reporting this. Door chime: good. Alarm: very bad. Please be aware.

It’s already broken

Had something similar at my business, very effective. I bought this one for home and installed it with tiny screws in a cinch. Great ! NOW I know when someone opens the door so I don't jump out of myself when I' m deep in thought. The plus side of it is, since it can be set to play many musical tunes, my dogs don't bark their heads off unless it's the regular door bell chime. They actually appreciate the sound and think it's the radio, TV or some other phone ringing. Whew!

Stuck to the door easily, we had a few milimeters gap due to the shaping of the old wooden door frame but it still works fine and simple easy instructions to pair with our existing bell system means reception are now alerted when someone comes through the door when they need to man reception. Thank you

Good

works well

I have people coming in and out all the time, and wasn’t hearing the door open. This took about two minutes to install, and I’ve plugged the “bell” into an outlet in my bedroom. Now I hear the door. There are many chime settings, including one that sounds like a doorbell!
