Most security products on the market today will only alert you after an intruder has entered. This door stopper will not only activate an ear-piercing sound but will prevent unwanted intruders from entering in the first place.
If an intruder attempts to enter, the alarm will sound and the unit will wedge underneath preventing it from opening.
The wedge-shaped design and non-skid pad on the bottom of the door stopper alarm will hold tighter the harder it is pushed. The sound will not stop until pressure is released from the metal plate.
Instructions - Place on the floor directly below the knob with the low end of the unit under the bottom edge of the door. Once opened, it will strike the metal plate, preventing the opening and the 120db alarm will activate.
This is also equipped with a movement sensor which will activate the siren if the unit is moved. A sensitivity switch allows you to adjust the amount of movement required to set off the warning. The unit operates with a 9-volt battery. Battery not included.
You're home alone, your imagination runs wild with every noise you hear, you automatically assume someone is trying to get into the house. What do you do? Do you get up and check every time?
If you are looking for an added sense of security while you are at home alone, the DSAL-2 is a good solution. This is a small but handy device you can use to know for sure whether someone is attempting entry.
Functions in two ways:
One, it lets you know when someone is trying to enter the home with a loud alarm.
The second is it prevents the intruder from actually getting in by wedging the door shut and physically preventing the door from opening.
This security device is placed on the floor, up against and underneath the bottom of the door. The sloped edge of the device is actually a metal contact. When the door is pushed up against the metal, it causes the alarm to go off alerting you that someone is actually trying to open it. Much better than wondering, right?
There is no difficult installation. Just install a 9-volt battery and place the item in front where the tip of the wedge is slightly under the door. When someone attempts to enter, that movement will push down on the metal plate causing the alarm to sound.
The 120db alarm will simultaneously scare away an intruder, alert the people inside, and make enough noise that someone else will be alerted and possibly summon help.
The base of the unit is forced downward by the pressure of the opening and makes it stay in place. This stoppage serves as a reinforcement base and actually prevents further opening.
The DSAL-2 is the ideal alarm for traveling while staying at a motel. Fits nicely in luggage and does not require external power. And if you are traveling out of the country, there are no converters needed.
You can use these on any entrance you want to protect. If anyone tries to gain unlawful entry, you will know it and the person trying to get in will know you know as well.
