In simple terms, burglar alarm systems are electronic systems that protect houses or workplaces from inside or outside or both sides and prevent unauthorized persons from entering. The advanced types of these systems not only provide audible warnings in case of theft, but also inform the home or business owner, security company and official security authorities according to the situation by using fixed and mobile telephone lines.

With the development of technology, alarm systems are no longer just a security measure against burglars and control other factors that threaten human safety. For example fire alarm systems and health alarm systems used for medical purposes.

Almost all alarm systems have alarm panels. Some of them are connected to a certain security center and some are not. alarm panels, which can be connected to a security center, have a digital communication element (communicator). In this way, the place to be protected is kept under computer control and recorded every day of the week and every hour of the day. Alarm panels, which are not connected to a security center, usually function with warning and deterrent sounders.

Alarm panels, depending on their characteristics, include elements such as magnetic contact, motion detector, glass break detector, external siren, internal siren and telephone dialer. In addition, flame resistant cables are used in fire alarm systems to operate under high temperatures. In all alarm systems, the most important reason why the system does not work as expected is that the wiring is not properly and correctly.

The establishment of fire alarm systems in order to detect fire and to take necessary precautions in production facilities, offices, gathering places, training buildings, accommodation facilities, health centers and many other places before the fire starts to be dangerous.

In addition, since all alarm systems operate with electricity, low voltage tests (LVD tests) should be carried out in order to avoid any short circuit or negative conditions, in accordance with the regulations of the Electrical Equipment Designed for Specific Voltage Limits is required.
