No matter what I do I can’t get them to set right.** A: The description may not be very clear. But it's really switchable. Let me give you more details. Push the switch in the OFF position (down), open the batteries box, take out the battery, reload the batteries, and cover the batteries cover. PUT THE MAGNET CLOSE TO THE HOST. Push the switch to ON position (up), then you will hear the first sound (default mode), which is alarm mode. Within 3 seconds, when you push the switch from OFF to ON, you will hear the second sound-continuous alarm mode; Within 3 seconds, when you push the switch from OFF to ON, you will hear the third sound-reminding closing mode; Within 3 seconds, when you push the switch from OFF to ON, you will hear the fourth sound-the doorbell mode. At this time, separate the small magnet, will emit a doorbell sound. After the mode has been set, if the switch is switched on to OFF again, the sound mode will be restored to the default alarm mode. In order to change the sound mode, it needs to be reset according to the above method. **Q: Are these packaged separate?** A: Yes, there are four separate packages. **Q: Our freezer door was left open again. would this work to let us know it was left open. can i turn it off when i need to get into the freezer?** A: If you turn it off to open the freezer and don’t turn it back on it won’t help remind you to close it. If you choose to keep it on it will make a sound (dependent on the setting you have it on) until the door is shut again. **Q: can we get new batteries after it stop working?** A: Thank you for your question. When the product arrives, three AG13(LR44) batteries are combined. It's not a special battery. this is it, https://www.amazon.com//dp/B07Q16ZPFC . When you need to replace the batteries, you only need to put in three separate batteries. I hope the above can help you. ## Customer Reviews ### ⭐⭐⭐⭐⭐ These alarm sensors work just fine. *by R***. on April 13, 2024* we have a 4 year old grand daughter that we don't go out in the yard by herself, as we have a pool.

Put the included batteries into the alarm, and then stick them on doors or gates with the included two sided tape. It can be flipped upside down to install on right or left openings. It has an on/off switch if you need to turn it off for a bit. I don't think it has different modes or settings. If it is turned on, and you open the gate or door, you get a loud blaring alarm. No bypass switch. I have these on my back door and another on my pool fence gate as a layer of safety for having little ones near water. ### ⭐⭐⭐⭐ Buy Extra Mounting Tape *by J***T on August 12, 2019* These alarms are VERY loud which is great, and they're easy to install EXCEPT for one thing...... If the window/door is flush with the frame it's a snap to install. I did 12 windows in about 5 minutes. However, I had to put these on 6 different exterior doors. Since one piece goes on the frame, and the other piece goes on the door there is a problem. My door frames are not flush with the wall. I think very few doors are. So I had to use extra mounting tape to make them even with each other. I'm not talking about an extra layer, I'm talking about close to a full INCH. Luckily I had a large roll of permanent outdoor mounting tape already, which I ended up using for everything and not using their mounting pads at all. Another issue with their mounting pads is if you remove it from the frame of your door or window it takes paint with it. The outdoor mounting tape is more reliable PLUS you can remove it with no damage to the surface. I bought the Scotch brand. Other than that I'm pleased and feel much safer now. I put them on every door and window in the house. Just know that you're probably going to have to modify one of the pieces when you install them on regular doors. ## Frequently Bought Together - Wireless Home Security burglar alarm, Magnetic Sensor Door Window Alarm, Super Loud 110dB, Pool Door Alarm for Kids Pack of 4 - HENDUN Wireless Door Alarms When Opened with Remote, Door Security Sensor, Pool Alarm for Kids Safety, Sliding (2 Pack) - HENDUN Home Security Door Alarms, 10 Pack,Updated Magnetic Sensor Alert, Window Alarms, Pool Door Alarm for Kids --- ## 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.tn/products/59779087-wireless-home-security-burglar-alarm-magnetic-sensor-door-window-alarm](https://www.desertcart.tn/products/59779087-wireless-home-security-burglar-alarm-magnetic-sensor-door-window-alarm) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-17*
