Advisor: Questions you should deal with before buying a door alarm
How does a door alarm work?
A door alarm almost always consists of two sensors. These are usually two magnets.
When the door alarm is installed, one sensor is attached to the door frame and the other to the door.
It is important that both sensors are at the same height, because as soon as you switch on the door alarm, the two sensors will contact each other.
If the door is opened unintentionally, the contact between the two sensors will be interrupted and the door alarm will emit an acoustic signal. The volume of this signal can reach up to 130 dB (decibel).
If you should accidentally trigger the alarm or want to switch off the door alarm, you can choose between different variants of a door alarm here.
For example, there are door alarms with remote control, pin code lock or key.
What types of door alarms are there?
The differences are in the characteristics that the door alarm can have. Most door alarms are a combination of several features. There are:
Door alarms with sensor
Door alarms with motion detector
Door alarms in the form of a door stopper
Door alarms with key or key switch
Door alarms with pin code
Door alarms with remote control
Door alarms with App
In principle, every door alarm works in the same way. Either a door alarm consists of two parts. Both parts are equipped with a sensor, which are in contact with each other.
If this contact is interrupted, the door alarm is triggered. Then there is a door alarm with motion detector, which is triggered as soon as it detects a movement in its radius.
In addition to the basic types of door alarms, there are various operating options available. Here you can choose between key, pin code, remote control and app.
In addition to the classic door alarms mentioned above, you can also opt for a door alarm in the form of a door stopper or wedge. This is triggered as soon as the door is opened and stopped by the wedge.
What does a door alarm cost?
There is a very wide price range for door alarms. The cheapest models start at just a few euros and many are already known as “alarm systems”, which are alarm sensors or motion detectors with an acoustic signal.
The higher the quality of the door alarm, the higher the price. An average door alarm has a price of ten to twenty euros.
Individual door alarms in a price segment below 100 euros are best suited to protect individual doors.
If you want to protect your whole flat or house against burglary, it is better to invest in a real alarm system.
Where can I buy a door alarm?
You can purchase a door alarm both online and locally. For the latter, we recommend a DIY store or a consumer electronics store.
According to research, this is the easiest place to find a door alarm:
- Media Markt
Why is a door alarm useful?
With a door alarm, you can easily retrofit doors and windows to increase the burglary protection of your home. It is also a cheap alternative to a complete alarm system.
Another advantage if you choose a door alarm with sensors is that the alarm is always triggered as soon as the two sensors no longer have contact with each other.
It does not matter whether the door has been levered open, a pane of glass smashed and then the door handle used, or whether the door was simply drilled open.
Also the installation is usually very simple. For this you should normally not need any further help.
What is a door alarm suitable for?
A door alarm can be used in many ways and is suitable for almost all doors and windows that are particularly vulnerable to burglary, for example the front door or patio door.
A door alarm is not only useful for securing entrance doors. Such an alarm system can also be attached to showcases or cupboards containing valuable objects that should not be opened by just anyone.
A door alarm can also be mounted on a refrigerator or freezer to prevent the door from remaining open.
In principle, a door alarm can be attached to any door that should not be opened by everyone. This includes, for example, an emergency exit or a fire door.
How is a door alarm installed?
Installing a door alarm is not difficult. Most devices can be attached to the door and door frame without drilling using the adhesive strips supplied. Some door alarms must also be fixed with small screws.
It is important that the recommended distances between the two sensors are observed. O
If both sensors of the door alarm are at the same height and are triggered as soon as this is no longer the case, you have successfully installed your door alarm.
What are the alternatives to a door alarm?
A door alarm is best suited for securing individual doors, but if you want to protect your entire home from burglars, you should choose a different protection.
As an alternative to a door alarm, you can choose an alarm system with video surveillance for burglary protection to be really completely safe.
Purchase criteria: You can compare and evaluate door alarms based on these factors
In the following we would like to show you which factors you can use to compare and evaluate door alarms. This will make it easier for you to decide whether a particular door alarm is suitable for you or not.
In summary, these are:
- Volume level
- Type of drive
- Type of triggering
- Possible applications
A door alarm can be installed in two ways: with screws or with adhesive tape. The latter is the more common variant.
A door alarm that is attached to the door frame with screws is not easily removed. So if a burglar should think of tearing off the door alarm to get around it, the screws will prevent him from doing so.
However, the screws will leave a damage in the door or in the door frame, which will be visible if you do not want to use the door alarm anymore.
As mentioned above, most door alarms come with adhesive strips that you can easily attach to the door and door frame.
It is a simple principle and the door alarm leaves no damage to the door afterwards. In the event of a break-in, the alarm can be quickly torn off by the burglar and thus put out of action.
You can distinguish between four types of operation: with key switch, with pin code, with remote control and with App. For all types of operation, it is important to note that they cannot be deactivated by everyone.
A door alarm with key switch can be switched on and off with the corresponding key. This keeps the handling simple and no mistakes can be made when arming.
However, the keys for the door alarm must be kept somewhere or can be lost.
A door alarm with pin code is a four-digit code that is required to activate or deactivate the door alarm.
This is usually generated automatically, but does not change afterwards. With a door alarm with a pin code, you do not need to keep a physical object, but remember the code to enter it.
A door alarm with remote control, similar to the door alarm with key switch, has only two possibilities: you can switch the door alarm on and off with two different buttons.
Again, the handling is kept simple, but the remote control must be stored somewhere.
A door alarm with App works similar to a door alarm with remote control. The function for switching the door alarm on and off is located in the associated app.
However, no physical object such as a remote control needs to be stored here and the door alarm can be operated from any Internet-capable device.
In addition, other properties of the door alarm can usually be changed in the app, such as the volume or the alarm tone.
The volume of most door alarms ranges from 100 dB to 120 dB. However, it is often the case that you can adjust the volume manually on the device. This feature is more common with door alarms from the higher price categories.
However, the highest possible volume is normally not loud enough to replace a real alarm system.
A door alarm is more suitable for protecting against night-time burglars, because if you are not there, it is difficult to hear the alarm sound.
Type of drive
Door alarms for retrofitting doors and windows are usually battery operated. This means that you can easily install them and don’t have to look for a power source to connect them.
Nevertheless, there is the possibility that you can get a door alarm that is connected to the power supply. This prevents the unwanted standby mode that occurs when the batteries run down. However, this makes the installation more difficult again.
For door alarms you can choose between two different variants with regard to the triggering time.
With the first variant, an alarm is triggered immediately if the secured door is opened. On the other hand you can buy a door alarm with a time delay mode.
This time delay is either fixed or can be set manually. The range of the delay is between five and thirty seconds.
A door alarm can be used in many ways. You can use it classically for doors to increase the burglary protection of your home.
It is advisable to pay particular attention to doors that are highly vulnerable to burglary, such as a patio door.
You can also convert a door alarm into a window alarm. The principle is the same.
However, if only the window pane is broken in the event of a break-in, without the window frame being opened, the alarm will not be triggered. In such cases, a glass breakage sensor is more suitable.
The same applies to important doors that must not be opened just like that, for example an emergency exit or escape route, a fire door, or a door in a nursing home where there is a risk that they may be damaged by a P
Another way to use a door alarm is to attach it to a refrigerator or freezer. If you forget to close the door properly, the door alarm can alert you.
Trivia: Worth knowing facts about door alarms
How can I change the battery of my door alarm?
Changing the battery of a door alarm is as simple as changing a remote control. Depending on how your door alarm is mounted, you may need to carefully remove it from the adhesive strips or screw it loosely.
Then you can easily replace the batteries in the drawer on the door alarm and put the alarm back on.
It is important to know that most door alarms with conventional batteries have a lifetime of several months.
However, many are not equipped with the function that they will beep if the batteries reach a low charge level. Therefore, you should check from time to time whether your door alarm still works.
This depends on the type of operation you have chosen.
If you have selected a door alarm with remote control, you will find at least two buttons on your remote control: one to activate and one to deactivate. This is an easy way to turn off your door alarm.
The same applies to a door alarm with key. At the door alarm itself you will find a lock where you only have the possibility to switch on and off. With the help of your key you can select the appropriate mode.
For a door alarm with a PIN code, you must enter the PIN code of your door alarm to enable or disable it.
If you have an app for your door alarm, it depends on what the operator offers you. There is the possibility to use the app as a remote control or as a pin code lock.
Where can I find operating instructions for my door alarm?
In most cases, the door alarm comes with an operating manual. However, if this is not the case, or you have lost it, you can also check the manufacturer’s site.
From time to time, you can also find instructions on how to use a door alarm in forums or on other websites. They were posted there because others have similar problems as you do.
