It works so well - very loud! My grandchildren are between the ages of 2yrs - 7yrs. We have an inground pool in our backyard. This alarm gives us a peice of mind, although we are still very protective of/watch the kids closely when they come over.Thank you,Katherine Soulliere ### ⭐⭐⭐⭐⭐ Top! Sehr lauter Türalarm 👍 *by on Reviewed in Germany 6 March 2026* Ich habe diese kleine Alarmanlage von innen an der Tür meines Kellerraums installiert, da dort unsere E-Bikes drinnen stehen. In einem Mehrfamilienhaus möchte man einfach etwas zusätzliche Sicherheit haben, besonders weil es leider immer wieder zu Kellereinbrüchen kommt.🔧 Montage & Installation:Die Installation ist kinderleicht. Alarmanlage und Magnet werden mit den beiliegenden Klebepads an Tür und Rahmen befestigt. Danach einfach zwei AAA-Batterien 🔋 einsetzen, schon ist das Gerät einsatzbereit.⚠️ Wichtig:Die Pfeile auf Alarmanlage und Magnet müssen zueinander ausgerichtet sein und sich gegenüberstehen. Der Abstand sollte idealerweise wenige Millimeter, maximal 1 cm betragen, damit der Sensor funktioniert.🎯 Bedienung:Die Aktivierung und Deaktivierung der Anlage, erfolgt über die selbsterklärende Fernbedienung. Der Alarm lässt sich so bequem ein- und ausschalten, was im Alltag besonders praktisch ist, zum Beispiel bei häufigen Kellergängen.Allerdings ertönen bei jedem Aktivieren oder Deaktivieren der Anlage laute Signaltöne an der Anlage, während gleichzeitig eine Signalleuchte an der Fernbedienung aufleuchtet.Persönlich hätte ich mir gewünscht, dass nur die Signalleuchte funktioniert, ohne dass zusätzlich ein Alarmton ausgelöst wird.📢 Lautstärke:Der Alarm der Anlage ist wirklich extrem laut.Wenn er ausgelöst wird, hört man ihn meiner Meinung nach im ganzen Haus. Genau das wollte ich erreichen, so wird sofort Aufmerksamkeit erzeugt und ein möglicher Diebstahlversuch wird wahrscheinlich schnell abgebrochen.✅ Fazit:Für meinen Zweck, den Kellerraum und unsere E-Bikes zusätzlich zu sichern, erfüllt das Gerät seine Aufgabe sehr gut.Einfache Montage, sehr lauter Alarm und unkomplizierte Bedienung.Preis-Leistung passt aus meiner Sicht ebenfalls.Ich würde die Alarmanlage wieder kaufen. Von mir eine Absolute Kaufempfehlung 👍 ### ⭐ No funcionó *by on Reviewed in Mexico 20 March 2022* Llego descompuesto ## Frequently Bought Together - HENDUN Wireless Remote Door Alarm, Windows Open Alarms,Magnetic Security Sensor, Pool Door Alarm for Kids Safety, Alzheimer's Apartment Alarm - HENDUN Wireless Door Alarms When Opened with Remote, Door Security Sensor, Pool Alarm for Kids Safety, Sliding (2 Pack) - Hendun Extra Remote for Wireless Anti-Theft Door and Window Security Alarm/Bike Alarm, Alarm System Remote Control Key Fob Replacement. --- ## 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.ro/products/257460946-hendun-wireless-remote-door-alarm-when-opened-windows-open-alarms](https://www.desertcart.ro/products/257460946-hendun-wireless-remote-door-alarm-when-opened-windows-open-alarms) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-08-16*
