Shop Silverline Door Stop Security Alarm 1 x 9V Battery (898104). Review: Simple, effective, and unbelievably loud - perfect for peace of mind! - The Silverline Door Stop Security Alarm is such a clever little device and it’s incredibly easy to use. It works exactly as described, and gives so much extra peace of mind. All you do is pop in the battery, place it behind the door, and it’s ready to go. No complicated setup at all. It’s really sturdy but sensitive enough to trigger as soon as any pressure is applied to the door, and when it goes off… it is SO loud (in the best way!) exactly what you want from an alarm. The sound is piercing and attention-grabbing, which makes it ideal for deterring anyone trying to open the door unexpectedly. It fits just like any other door stop (I was initially worried it would be too bulky), and the battery life seems good so far. Such a simple yet effective bit of security kit. It's lightweight enough to take when travelling too. I’m really impressed and would 100% recommend it for that extra layer of safety. Review: Keeps the burglars and sweets-snatchers out - I bought two of these door stop alarms primarily since the missus is somehow uncomfortable being alone in our second home abroad. So I ordered two of these ‘guards’ one for the front and back door each. It’s a pretty simple electronic product that has been around for decades - my parents used to have a very similar door stop alarm in the 1980’s, made of plastic and thin metal. But it works well. That is, it will sound the alarm. And it will perhaps cause some small additional obstacle to open a door. It’s reasonably sturdy. But somebody using force will still be able to open any door with such a stopper behind it. Either way, my wife feels much more at ease. And compared to investing 10x more for a half-decent alarm system I would say its good value for money. It does require a 9V battery. Now, since I had these lying around my daughter has put them to use to guard her bedroom. She is suffering quite a bit from a little sweets-snatcher (her younger brother). That tends to sneak into her bedroom, browse through her stuff and help himself to her sweets. The Very loud alarm already gave him a few scares during his frequent raids and might lead him to give up his despicable efforts. So except for the little looter, most are happy and pleased with this door stop alarm. ## Features - Wedge door stopper alarm with 3 sensitivity settings - high, medium and low. - Emits an ear-piercing 120dB alarm to provide security and an effective deterrent to intruders and opportunist thieves. - Sensitivity can be adjusted to avoid false alarms. - Ideal for use at home, workshop, garage and also dorm rooms and hotels. - Easy and effective way of protecting yourself and your belongings, providing security and peace of mind. - Compact design for discreet positioning at entrance points. - Can also be used as a traditional door stop when switched off. - Cost-effective and more comprehensive than a traditional alarm system. - Requires 1 x 9V (PP3) battery. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B015HMKRVC | | Batteries | 1 Product Specific batteries required. | | Batteries Required? | No | | Batteries included? | No | | Battery Cell Type | Alkaline | | Best Sellers Rank | 43,900 in DIY & Tools ( See Top 100 in DIY & Tools ) 325 in Door Stops | | Colour | Multi | | Customer Reviews | 4.3 4.3 out of 5 stars (1,281) | | Date First Available | 17 Sept. 2015 | | Finish | Brushed | | Included Components | 1x Door Stop Security Alarm | | Item Package Quantity | 1 | | Item Weight | 80 g | | Item model number | 898104 | | Manufacturer | Silverline | | Number of Pieces | 1 | | Part Number | 898104 | | Plug profile | Floor Mount | | Product Dimensions | 23 x 5 x 13 cm; 80 g | | Size | 1 x 9V (PP3) | | Style | Compact,Traditional,Wedge | ## Images ![Door Stop Security Alarm 1 x 9V Battery (898104) - Image 1](https://m.media-amazon.com/images/I/51pohiA-hoL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Simple, effective, and unbelievably loud - perfect for peace of mind! *by K***T on 18 September 2025* The Silverline Door Stop Security Alarm is such a clever little device and it’s incredibly easy to use.

Great value. *by A***R on 19 August 2018* Unfortunately these don’t work on the external doors I had hoped to use them on as my UPVC doors are in a frame and not flush with the floor. However I have tried them out on some internal doors and they are perfect. So easy to use with a really loud sound so I am hanging onto them for when I stay in a a hotel. Really great value too. --- ## 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.gr/products/48806848-door-stop-security-alarm-1-x-9v-battery-898104](https://www.desertcart.gr/products/48806848-door-stop-security-alarm-1-x-9v-battery-898104) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-04-23*
