Item showd up used. A waste of time.

This product is great. I wasn't able to install it on the wall, as I had planned, because the adhesive wouldn't hold, but I think it was more because of the textured wall paint than the adhesive itself. I ended up installing it directly on the door and that was very easy and worked fine. Reading the description and reviews I wasn't entirely sure if there were 2 bypass buttons (one for inside and another for outside) but there are 2. The inside bypass button is on the unit itself. The separate, wired bypass button shown in the pictures goes outside. I don't have a sliding door, or a screen door, so am only using 1 set of sensors. The alarm is definitely loud enough to be heard throughout the house and the bypass buttons couldn't be easier, making this alarm a great safety feature instead of the incredible annoyance it would be without the bypass buttons. Highly recommend. Note, my town doesn't have specific standards for the alarm other than that it is constantly armed, sounds for 30 seconds, and can be heard through the house.

THIS IS THE BEST POOL DOOR ALARM: In the world of pool safety this is the GOAT door alarm. Looks like a ring alarm on the we all. This is the best product I have found due to bypass feature which allows the adults and tall peoplr to open the door and close it without setting off the alarm. The double sensor is so you can leave the sliding door open and the screen door closed. I lost my nephew on the 4th of July, 2020. If they had these he might be alive today. That is why I made a video and taking my time on this review. It is the ONLY well thought out pool alarm that's not annoying to use and safe. Most of the other ones for non have a bypass button. I would throw that away in a week. For only $50 it's affordable and easy to use. You have no excuses, if you own a pool you need one of these. I'm happy to review any similar products that can match or beat this one but I couldn't find any competition after searching for hours .

I purchased four of these and they all work fine. I used command strips to stick the main unit to the wall and painters tape cut into small double-sided strips to stick the sensors and extra bypass switch. I did this so I can remove everything without damaging the wall. My doors are not on the same plane as the interior wall because there is moulding around all of the doors. This makes it a little tricky to place the sensor wired to the unit, but fortunately there is enough "allowable gap" in the sensor's sensitivity that it was not a problem for me. The alarm is very loud and cycles through different sirens. I was concerned about passing a town inspection (strict pool rules in a town near Boston, MA) but these units were fine. I don't intend to use these regularly but if I did my one complaint is that the wire to the extra bypass button / switch is very short, as are the wires for the extra pair of sensors. So much so that I couldn't set it up to be used on the screen doors. If you want something that is going to work on the main door AND a screen door, these may not work in all circumstances. Otherwise they served the purpose I needed.

The device works as intended but the wires are much shorter than they should be. I have no intentions of drilling through my house wall which might make the wires long enough for the install. I was barely able to get the override button outside from the inside unit. This passed through a screen door and sliding door frame, or about 7" of wall thickness. Any farther than that, this will not work for you.
