Description

A burglary occurs every 14.5 seconds in the U.S., and budget cuts have led to an average 911 response time of 10 minutes. Furthermore, without the ability to install a home security system, renters and travelers can have a hard time feeling secure in their temporary housing. SABRE’s Door Stop Alarm is a great solution to either help fortify an existing home alarm system or use on its own in a bedroom, dorm, hotel room or apartment. The extremely 120dB loud alarm is audible up to 1,500-feet (455-meters) away and sounds when door pressure is applied. It is compatible with doors that have a 0.75" gap between the floor and bottom of door (if the gap is greater, the alarm will not be able to activate when the door is opened). The alarm is coupled with a non- skid pad to prevent the door from opening. This attractive, premium white alarm installs easily in just seconds – simply slide it under the crack of an inward-swinging door. There’s no wiring needed, so the alarm works during power outages. Requires 1x9V battery (not included). A small Philips Head 1 size screwdriver is required to remove battery compartment cover. For an extra level of security, the Door Stop Alarm provides a battery status update via a low battery indicator. The Door Stop Alarm was developed by SABRE, the 1 pepper spray brand trusted by police and consumers worldwide, meaning this product is extremely reliable. Backed by over 45 years in the security industry, SABRE products must pass rigorous quality assurance testing before leaving our facilities to give you peace of mind. Improve your home security today.

  • Great doorstop for deterent.
Color: White
Extremely loud—exactly what I was looking for! The alarm is very sensitive to pressure, which is perfect for situations where you need to deter intruders. The build quality is solid for a simple doorstop, and it’s easy to wedge under the door. The only downside is that it won’t work on doors with a large gap at the bottom (around 2 inches or more). Overall, highly effective and reliable. Thanks! ... show more

  • A great little security alarm.
Color: White
Works as advertised. Inserted a 9 volt battery, turned it on, set it in front of the door, opened the door, and it sounded a very loud alarm. Easy on and off switch. Low battery warning light. Works just liked I hoped it would. Will be great peace of mind when traveling. Thank you!

  • Great Item.
Color: White
Great for travel and home/dorm use. The alarm is super loud. It should wake the neighbors and the dead. The batteries are not included, but are easy to buy on Amazon. Also easy to change the batteries. Highly recommend.

  • Function depends especially on your floor surface. Solution provided inside the review :D
Color: White
It's simple, it's effective, but proper functioning depends on your floor surface. For those who don't want to read thru the end....Conclusion: This is a great and simple solution to keep people from entering your home, while you are at home. But you have to buy additionally a 9V block battery, need a micro screw driver to place the battery and you have to buy a simple fastener solution (see below) for slippery floor surfaces (e.g. wooden floors, stone or tiles) Delivery: I bought it on Amazon. Delivery was this time one day late. Opening: The packaging of the Alarm is tricky to open. Its completely blistered. This is not very Eco-friendly and you need strong household scissors to open it. Content: Just the Alarm, A short 1/4 page instruction. NO battery included. you need to buy a 9V block battery separately. Installation / Functioning: First you need to buy extra a 9V battery... if you realize this only after the packaging arrived, this might be quite bothersome as many households will have AAA or AA batteries always at home but not 9V block batteries. The installation of the battery requires a micro screw drive. A normal screw driver will not get you far as you wil just damage the screw head. Battery once installed you should be good to go. The alarm is loud and it works very effective. But I have a wooden floor and the device always slid away when opening the door. The rubbers on the bottom would hold strong enough to the ground. So I bought this Scotch Reclosable Fasteners, Clear, 1 x 3-Inches, 2 Sets (RF9730) to hold it strong to the ground and the door cannot slide it away. ==> this works perfectly. 1) The door is completely and very tight blocked! This keeps intruders from entering your home AND 2) you can remove the alarm easily while this scotch fastener consist of two parts. One sticks to the floor and the other to the alarm and you can peel the device off any time easily from the floor. 2) The alarm goes safely off if the door opens and cannot be switch off by the intruder - given you have placed the alarm fixed to the ground with the fastener close enough to the door. Final rating: As the obligatory 9V block battery is missing and additional investment into a fastener solution for slippery surface is needed (depending on your home) i can unfortunately only give 4 stars. Once installed properly it works perfect. Open question remaining: How long will the battery last? ... show more

  • Very good door security alarm.
Color: White
Does what it says it does and more — Acts as a wedge to a door, may slow an intruder down and loudest observed alarm. When activated by a door being opened, the piercing alarm is phenomenally loud. I felt better that the fiancé used it while on travel. Though it will not stop an intruder, it will wake up the user, those around you, and the piercing shriek of the alarm may scare the intruder away. Easily carried in a briefcase, I would recommend this to weary travelers, especially when staying in hotels without your standard “door bar” as found on US hotel doors. Door chains can be easily and quietly cut, allowing an intruder unannounced in your room—F-BOMB THAT! The design of this model has an extended sloped wedge longer than models I bought and compared, which allows the wedge to better slide deeper under a door, further acting better as a door wedge to slow an intruder. Compared to other models, the only negatives I found was lack of directions to install the battery and more difficulty to install the battery (you need a micro hex screw driver to remove the battery cover and then attach wires, where in others you unsnap the battery cover and press in battery). I would recommend this to travelers, especially women travelers (who statistically are at higher risks of more assault related crimes). This device should alert you when someone enters through your door—who wants to wake up with some turd 💩 thug with HIS hand over your mouth and a knife at your throat.....or worse yet, the 💩 doing this to your lady. ... show more

  • Personal Safety
Color: White
This was recommended by a retired cop on social media. It works for apartment, hotel, room. It’s very sensitive and will wake you. Sturdy and reasonably priced. I would recommend this to all women.

  • Door entryway lip height matters!
Color: White
Make sure your door is low enough so that it presses against the lower front tip portion of the silver aluminum trigger of the alarm. If your door sits on an entryway lip, so it's elevated in relation to the inside ground level, and hence will only touch the higher back end of the silver trigger when opened, then the alarm will not sound off. In other words, you would think that having any part of the silver aluminum trigger being touched by the door would set off the alarm, but that's not true. Only the front lower tip area activates the alarm, and not the back part that's higher up and closer to the alarm speaker. Otherwise it seems built well enough for the price. The alarm sound is very loud, no way you won't be woken up to it. ... show more
