Silverline Door Stop Security Alarm 1 x 9V Battery (898104)

Product Information

You’ll want to think about the potential risks you’ll be taking throughout your trip, from getting there to exploring your destination, and while staying at your hotel or Airbnb. Travel safety products range significantly from items focusing on solo female travelers’ personal safety to items that protect against theft. Think about where you’re going and what makes the most sense for the destination or type of travel you have in mind, and go from there. A fire door retainer is a legal solution to holding open fire doors, improving ventilation and ease of movement around a building, which is particularly important for disabled access. It is common, but illegal, to hold open a fire door using a chair or an extinguisher; the door would not be able to stop the spread of flames and smoke, making it unsafe. Fire door retainers are automated devices which respond to the activation of a building’s fire alarm, releasing to close the door in the event of a fire. The Sabre door stop alarm’s combined protection method proved highly effective in our test. After turning it on and placing it as close to the door as possible, we attempted to open the door. The alarm was triggered immediately, even before the door motion stopped, and it was piercingly, painfully loud. The wedge stopped the door from opening almost immediately, with less than 2 inches of movement. In testing, the lightweight door bar proved very easy to install and use and offered an excellent strength-to-weight ratio. Basic installation in the sliding-door frame required just two screws. The telescoping adjustment feature, which works by friction instead of spring buttons or pins, offers unlimited positioning between the minimum and maximum lengths. The optional childproof latch is easy to operate one-handed. We also liked how it folds up into a visually unobtrusive position parallel with the door frame when not in use.

Some bars work for both hinged doors and sliding doors, and they adjust to different sizes, depending on how the bar is configured. If using a bar for a hinged door with both the base and yoke in place, the maximum length will be longer than if removing the base and the yoke for a sliding door. The Door Wedge Alarm works through being placed on the floor close enough to the door (perhaps a few inches) which permits the door to be left ajar slightly but prevents it from being forced open. Ideally, situate it about 30cm from the opening edge of the door so that it cannot be reached from outside. Sabre’s door wedge easily slides under an inward-opening door and sounds off a 120-decibel siren when someone applies pressure to the door in a break-in attempt. The alarm is loud enough to be heard up to 1,000 feet away. The door wedge needs a 9-volt battery to operate, and it provides a battery status update with a low-battery indicator. The metal plate doesn’t look like it may wear off anytime soon (although I doubt that you will constantly slide the door over it) and the plastic case is as you may expect at this price point: decent, but not very rugged. For this reason (and because of some openings around the case), the device is suitable for indoor use only and it will not survive the external conditions, especially rain, which will easily fry the internal circuitry. At the top of the door stop alarm, there is a circular protrusion for the internal speaker, where you will also see a red LED (that will flash when the battery is low) and, on the rear side, there is an On/Off switch which is useful for turning off the alarm and for regularly testing it to make sure everything functions properly. On the bottom of the device, there is only a small portion covered by rubber and near the middle, there is the battery container. In terms of size, the device measures 9.0 x 5.5 x 2.2 inches, so it’s slightly larger than both the Sabre and the EMDMAK door stop alarms and, considering that it weighs 0.31 lb, it’s not the heaviest device in its class. Does this mean that it will easily slide when the door is being opened? It does have a textured rubber pad attached to the bottom to prevent the door stop alarm to slide, but it still can move around depending on the type of floor that you have in your home. Since this can negate the usefulness of the door alarm, you can should use double-tape or some reclosable fasteners to make sure that the device will stay in place (although that will take away from its portability factor). The topmost part of the door stop alarm is plain, but there is a small bump with some openings on the sides for the internal speaker; there’s also a small LED which will flash red when the batteries are low.The concept behind pretty much every door stop alarm is the use of a metallic plate which sits at an angle on a plastic case (with a slight elevation due to an internal spring) and, when there is pressure applied on the metallic part, it triggers the audible alarm. So, it doesn’t require anything fancy such as a WiFi connection or anything of the sorts that can be bypassed using a jamming device (creates RF interference), you just have to assure that it’s powered on (usually by a battery) and that it is positioned close to your door. The Sabre door stop alarm is built on this exact premise, so expect a relatively small plastic case (it measures 6.0 x 2.2 x 10.8 inches) with a triangular shape almost entirely covered by a white matte finish and, about midway towards the tip of the device, there is a metallic plate (which seems to be steel) slightly elevated by the expected internal spring. A: Simply put, door alarms are wired or non-wired devices that are designed to be easily installed. Door alarms work with a magnet and sensor. When the alarm is programmed to alert, the circuit that is attached by a magnetic current will trigger and sound an alarm should the magnets separate. In a nutshell, they are a straightforward device that can offer a whole lot of peace of mind for the entire household. Q: How do door alarms work? The alarm is battery powered for convenience but may also be used as a normal door wedge simply by switching the alarm to the Off position .

A: Almost all door alarm sensors on the market right now will use a ‘reed switch’ that is able to determine when a protected area has been breached. A reed switch is made up of a set of electrical connectors that are placed just slightly apart. Once a magnetic field is parallel to their electrical connectors, they are pulled together which closes the circuit and ultimately sounds an alarm. Fire doors are an important part of any building's fire safety strategy as they enable movement throughout a building while stopping the spread of fire to allow occupants enough time to evacuate safely. However, fire doors can only function if they are closed or close automatically if a fire occurs. This is the reason why it is dangerous and illegal to hold fire doors open with a wedge or extinguisher. Door wedges squeeze underneath a door. Made of plastic and possibly steel, wedges grip to the floor when pushed on, helping to prevent entry.
