External alarm

An external alarm is an alarm system used to warn people in dangerous or potentially dangerous situations. It can be triggered by both audible and visual alarms, such as sirens and strobe lights.
In general, private homes, apartments and businesses have an external alarm. Its purpose is to prevent burglars from entering and to scare them off.


The signal sent by External alarm is emitted both on-site and at an external location such as an emergency call center. This attracts attention both in the building and in the responsible emergency call centers. This allows police and fire departments to respond quickly to potential threats.

External alarms provide an effective deterrent against intruders. They ensure that their loud alarm signals attract the attention of people in the vicinity. They may then be able to assist in repelling the threat.


Compared to the silent alarm, it was designed to attract a great deal of attention. It also directly informs everyone involved about the situation.

It gives additional security to the residents or employees. Therefore, the alarm system is especially suitable for buildings without private security.


External alarms have various functions and features to detect hazards quickly and reliably. Fires or forced entry are detected via corresponding sensors. This allows both temperature changes to be detected and intrusion to be detected by means of magnetic sensors in windows and doors.


Should the data reach a critical point, the message is immediately forwarded to the signaling devices. Sieren or flashing lights as acoustic and optical alarms immediately inform the persons concerned and service control centers. At the same time, they put the perpetrators to flight. Depending on the type of External alarm, additional components such as motion sensors or external cameras can be added to improve functionality. Once the system is installed, users usually have access to a mobile app or some kind of user interface.


Through this, they can make settings:

  1. setting up alarm zones and adjusting alarms based on the type of threat detected (e.g., burglar detected vs. fire detected).

Application areas

External arms are most often used in residential areas. However, they can also be used in commercial areas such as retail stores or warehouses. There, there is a higher risk of fires or burglaries.

In addition, External alarms are used in businesses and public buildings that do not have regular security personnel, but still need reliable protection for their assets and employees.


Overall, they provide a flexible and effective way for individuals and businesses to protect themselves from potential threats. They also allow emergency services to respond quickly when they are needed most. Furthermore, External alarms also serve as a psychological deterrent to criminals. Additionally, an External alarm gives a sense of security to the individuals involved.
