UltraPro Personal Security Window and Door Alarm, 1 Pack, Wireless Chime

These work really well and stay on. Easy set up and they are loud enough to hear.

It’s easy to set up in the doors and windows too, it’s really loud - the chime is loud that from the kitchen door I can hear it clearly from my bedroom which is about 50ft away. The alarm is so loud - it will spook anyone opening the door and windows.

This product was purchased to keep my little escape artist inside the house. We installed locks he can't reach but, since other people go in and out, there's no way to guarantee they stay locked ALL the time. This handy device helps fill the gap by making sure mama knows EVERY time someone goes through the door! It's VERY easy to install -- if you don't have any trim around your door. If you have trim, you'll need to either forego the alarm or cut into the trim to make a space, because this needs to sit flush. But assuming you have the space for it, just make sure the area is clean and dry and stick it on with the (included) adhesive foam strips. It comes with batteries already installed; you'll just need to remove the piece of plastic preventing them from making contact so they don't burn out prior to purchase. They are, however, some weird button batteries, so when it's time to replace them, they can't be replaced with a trusty AAA. The overall device -- both pieces -- is a little smaller than I had anticipated. I'd say it's a little smaller than two side-by-side boxes of matches. It has three settings: off, alarm, and chime. Off is pretty self-explanatory. I assume if it's set to alarm, it will go off continuously when the door or window is opened. We keep it set on chime, so it goes off once every time the door is opened. It makes a very loud, obnoxious digital chiming sound; you've probably heard it if you've ever been in a store that announces your presence with an electronic chime. It isn't a very pleasant sound if you're standing right beside it, but I'm able to hear the downstairs door from upstairs, so there are benefits to its being as loud as it is. I wish it were designed to use a AAA battery, because the button batteries are exceptionally hazardous around children, but I have no complaints about the alarm's functionality.

Initial impressions only. First thing to note - make sure you have a very small Phillips-head screwdriver for the battery case. If you have an eyeglass repair kit, it will work. Secondly, I bought this set specifically for the chime feature. I have varying needs for the door/window sensors from "this window should never be opened and will be alarm-setting only" to "this door is opened often and I just want a chime on it to alert me during the day." Very few sensors, even at higher price points, have the chime, so I can't be too picky, but it's LOUD and very high-pitched - it's less of a chime than a screech. It's a short blast of the alarm. Someone with average hearing will be able to *clearly* hear the chime from the other side of the house. When in the same room, it's too much. My plan to keep most of the sensors on chime during the day isn't going to work. I will give myself and my cats heart attacks every time the chime is activated; it's not the neutral "bong" I was expecting. Luckily, the switch to adjust the settings are easy to reach so you will just have to get in the habit of resetting it as needed. I'm not looking forward to testing each one as I install them, but, again, at this price point, it's a small inconvenience. Finally, each sensor requires 4 LR44 1.5v batteries. Go ahead and toss a bulk pack into your cart now while you are thinking about it. Another positive is the large battery test button on the front. It's easy to check if you need to replace the batteries, and the notification is a change in the light color, not an alarm.

Does exactly what I needed. I have a special needs toddler and this works prefect for some added peace of mind if she opens doors, windows or drawers she doesn’t need to be opening. Loud alarm and easy to install. Super happy with product and pricing!

One of our doors became disconnected from our alarm system. The alarm company wanted to charge us well over $1,000 to reconnect it. This GE Personal Security alarm saved us a lot of money and works wonderfully. It is very loud so we can hear it from any room and it's easy to turn off , on chime and in alarm settings.

We purchased these for the doors on my father's home. He has begun to exhibit signs of dementia and will occasionally get up and wander around the house at night. The alarm is nice as you turn it on and off and can set it to either the "door bell" ring or the blaring siren; both loud enough to hear from all over the house. They were easily installed in mere minutes. The only complaint that i have it that the tape does not hold up over time. We have had to replace the tape they came with, using double sided gorilla tape instead. Overall, a great alarm.

Boy are these LOUD!!!! Excellent, cost-effective home security devices. As a single mom, I feel so much safer at home with these installed. Don’t hesitate to buy these!! I know I’ll definitely be getting more!

The sensors work great

I live in a somewhat remote rural area, and in a house with a number of downstairs windows and doors. For security reasons, and following some minor thefts in other properties nearby, I needed either a full alarm system or individual alarms for windows and doors. I saw these, and thought I would give them a try. There are two parts to each alarm - the main alarm and a smaller, magnetised piece that fits on either the door/window or door/window frame. The parts are attached to window/door by the supplied double sided sticky patch (this is a surprisingly strong bonding sticky patch, and I have no doubt it will remain in place for some time). The two pieces of the alarm shoould be attached in such a way that there is a narrow gap between the two parts. To turn the alarm on one simply moves the side switch on the main alarm piece down as far as it will go. (Moving it half way down gives a single chime when the door/window is opened). To turn off the alarm simply close the window/door, or physically move the switch to the 'off' position. The alarm itself is quite loud (110 - 120 decibels - I have seen both quoted in literature and on the box! Whatever it is, it's loud!) This package, with 12 alarms for £50 (the price I paid) has turned out to be good value as far as meeting what I needed, the ease of installation and the noise each alarm makes when triggered; as such I can recommend them. (These are my own thoughts on an item I have bought myself and found useful.)

Compre el paquete que incluye seis y son realmente faciles de instalar. Traen un plastiquito adherente de 3M para pegarse a cualquier tipo de superficie muy resistente. Necesitas un desarmador para poder activar las baterias. Me siento mucho mas seguro en casa, el ruido de la alarma que hacen al activarse es muy alto y todo mundo se dara cuenta cuando alguien intente entrar a tu casa.

Gets the job done. Sound is impressive. Pretty loud for a small product like that. Would highly recommend it.

Very effective and LOUD!
