Designed for homes, apartments, dorm rooms, offices, RVs and campers, each alarm emits a powerful 120-decibel alert that helps discourage intruders the moment a door or window is opened. Installation is fast and wire-free. Use the included double-sided tape to mount the alarm and magnet in minutes, with no tools required. When the door or window separates the base from the magnet, the alarm activates instantly. An easy-access chime/OFF/alarm switch lets you choose a gentle chime for daily monitoring or a loud siren for security situations. Beyond doors and windows, these compact alarms work well on cabinets, drawers and interior spaces where awareness matters. An LED indicator alerts you when battery power is low, while four included LR44 batteries ensure out-of-the-box operation. With straightforward setup and dependable performance, UltraPro Audible Window and Door Alarms provide peace of mind without complicated installations or ongoing costs.

Great value for the price! Review: Absolute Game Changer for Our Family’s Safety - As a parent of a disabled child who sometimes wanders at night, this little device has brought us peace of mind we didn’t know was possible. The GE Personal Security Alarms are simple, affordable, and incredibly effective. We placed them on bedroom doors and windows, and now if she opens one in the middle of the night, we’re instantly alerted. The alarm is loud enough to wake us up, but not overwhelming, and the install took literally seconds—no tools, no fuss. It’s a true DIY win that doesn’t feel like a compromise on safety. Knowing we’ll be alerted immediately if our daughter tries to leave gives us a sense of control and security that we’ve been missing. Honestly, this product has changed how we sleep at night—and that’s priceless. If you're caring for someone with special needs or just want a reliable home alert system, don’t hesitate. This has made a world of difference for our family. 💜 ## Features - 120DB DOOR AND WINDOW ALARM — Deters intruders instantly using a reliable magnetic sensor, with selectable siren or chime alerts when doors or windows open or close - SIMPLE ALERT CONTROL — Side OFF/chime/alarm switch lets you match security needs to daily use, includes four alarms for broader indoor entry point coverage - WIRELESS INDOOR INSTALLATION — Uses included double-sided tape for fast tool-free mounting on doors, windows, cabinets or drawers, no wiring required - BATTERY-OPERATED SECURITY ALARM — Runs on four included LR44 batteries and features a front LED low battery indicator for dependable everyday protection - TRUSTED HOME MONITORING SOLUTION — Designed to add a layer of awareness and confidence in houses, apartments, dorm rooms, offices, RVs and campers; no apps or monthly fees required - 2-pack of battery-operated magnetic window/door alarms - Easy installation of alarm and sensor; no wiring required - 2 sound settings--120 dB siren and door chime greeting; easy-access off/chime/alarm switch - Battery-test button and indicator light; 4 batteries required each (included) - Measures approximately 1-1/4 inches long by 4-1/2 inches wide by 5 inches high; 90-day limited warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00178HMCI | | Audible Noise | 120 db | | Battery Description | LR44 | | Best Sellers Rank | #20 in Home Security Systems | | Brand | UltraPro | | Built-In Media | 2 Alarms | | Color | White | | Compatible Devices | Tablet,Smartphone | | Control Method | Touch | | Customer Reviews | 4.5 out of 5 stars 25,393 Reviews | | Global Trade Identification Number | 00043180451156 | | Item Dimensions L x W x H | 2.3"L x 0.6"W x 2.3"H | | Item Type Name | UltraPro Personal Security Window and Door Alarm | | Item Weight | 3.2 ounces | | Manufacturer | Jasco Products Company | | Mfr Part Number | 45115 | | Model Number | 45115 | | Mounting Type | Window Mount, Door Mount | | Number of Batteries | 4 Nonstandard Battery batteries required.

Will these damage the walls/windows when removed after a week?** A: The ones I gor today actually did come standard with 3M double sided tape and it sticks great. Dont know if it will damage after being on a few weeks but ai was able to pull it off the wall after about 30 min and no damage. **Q: I can see they have buttons/switches, are they easy for young children to mess with?** A: We use this on our son's door. We have it up high where he can't reach it. the sliding button is very tiny and I'm sure they could mess with it if it were in their reach. I had my husband mount it as high as he could. I stood with my arm up so I could reach it cuz I'm shorter than him, lol. My son doesn't touch it out of fear of hearing the noise go off. If the door is open (connection broken) and you turn it on it will chime or "bong" continually until the door is closed. Once my son heard the loud noises he doesn't go near it, lol, plus it's too high anyway. They're cheap enough to give it a whirl for you, but works like a charm for us! We showed our son, "If you open this door, this is what will happen!" and let it go off. **Q: Can this alarm be installed on sliding doors?** A: Since sliding doors design vary based upon manufacturer it's hard to accurately answer this request. However, if you can adhere both items of this product side by side - one being stationary, the other being the movable piece, then it will work just fine. In other words, when the sliding door is in the closed position, you must be able to install this product in such a way that when the door is opened, the two pieces "break contact" with one another thereby sounding the very loud and high-pitched alarm. Hope this helps. **Q: I found the chime setting extremely loud. is there another product that has a little more bearable chime sound?** A: Gab, unfortunately the chime sound is around 90 decibels and there is no way to lower that volume. As for any other products that the chime is a lower volume there isn't any that we manufacture.

I've had these installed in my flat for about four months now. Four stars because "I like it", but that's because I don't expect anything that it can't deliver. Let's get real: these are rated highly because they're extremely loud and very inexpensive. They're not rated highly because they are advanced security. They're great for guarding against the kids opening something they shouldn't, and they're so-so for using as a door chime (it's much too loud to keep on all the time, but a good defense against small children wandering away). I bought them so I can truthfully tell my insurance company that I have burglar alarms installed, to get a home-security discount on my property insurance. I'll be taking them with me when I move out to another home. I'll say it again: the siren is LOUD. It will most definitely cause temporary (or permanent) hearing damage if you're exposed to it for more than a few seconds at a time. Even the chime (a loud, shrill, electronic 'ding-dong') hurts a bit if you're right under it when it sounds. Even so, if you're truly serious about protecting yourself against burglary or home invasion, then for goodness' sake, spend more than $9. With proper placement, will this startle the bejeezus out of someone breaking in? Yes, but only briefly. Anybody with half a brain will be able to locate the siren within a few seconds, and will probably notice the easily-accessed switch on the side to turn it off. That means this alarm is really only useful if A) the burglar is easily scared off, or B) there's somebody around to hear it and investigate. I knew that when I bought them, and was fine with it. They do exactly what I expect them to, and they do that limited thing very well. They were easy for me to install. I took about 10 minutes with each one, determining the best way to install it on my flat's wonky doorframes, testing tolerances and distances, and installing carefully. If you wanted to install them in 90 seconds each, though, you could easily do that. They come with custom-cut 3M Command Strip adhesive pads. Peel, stick, press, peel, stick, press, done. They use included button-cell batteries. A green LED flashes when the siren sounds to show that the unit is working correctly; it doesn't stay lit. This will probably not protect your house while you're on vacation, but it will keep your smaller children where they're supposed to be, and will likely protect your doors while you're sleeping at night. For $9, that's a pretty great deal. ---12/10/2014 ORIGINAL REVIEW--- Temporary two stars because the speaker in one of the alarms was dead right out of the package. The LED turns on just fine, but no noise gets emitted. The other unit is fine, and works quite well, but what good is a two-pack when only one works? Currently working with Amazon to get a replacement, and will update with a full review once I have a fully working package. ## Frequently Bought Together - GE Personal Security Window and Door Alarm, 2 Pack, DIY Protection, Burglar Alert, Wireless Chime/Alarm, Easy Installation, Home Security, Ideal for Home, Garage, Apartment and More, White, 45115 - AceMining Upgraded Door Security Bar & Sliding Patio Bar, Heavy Duty Stoppers Adjustable Jammer for Home, Apartment, Travel (1 Pack,White) - Ring Battery Doorbell, Head-to-Toe Video, Live View with Two-Way Talk, and Motion Detection & Alerts (2024 release), Venetian Bronze --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/1300786-ultrapro-personal-security-window-and-door-alarm-2-pack-diy](https://www.desertcart.jp/products/1300786-ultrapro-personal-security-window-and-door-alarm-2-pack-diy) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-31*
