Security systems are mainly burglar alarm systems, security camera systems, fire detection systems and card access systems.

Burglar alarm systems include the following basic parts: burglar alarm system panel, pır (motion) detector, magnetic contact (door window sensor), glass break detector, optical smoke detector, temperature detectors, flood detectors, panic buttons, gas detectors, telephone search module, gsm dial module, outdoor siren with flashers, indoor ambient light siren, remote control, active infrared detectors, vibration sensors and power supply of the system.

Security camera systems include the following basic parts: digital recorder (DVR), network recorder (NVR), computer-based digital recording cards, security cameras, fixed security cameras, dome security cameras, fixed IR security cameras, security camera enclosures and feet, matrix device and security system monitors.

Fire detection systems include the following basic components: fire detection panels, fire repetition panels, optical smoke detectors, ionized smoke detectors, temperature detectors, temperature and smoke integrated detectors, fire buttons, fire sirens, flashing sirens, fire detection system modules, carbon monoxide detectors, explosive gas detectors, duct type smoke detectors, active air suction detectors, beam and light detectors and flame detectors.

Card access systems include the following basic parts: card access system software and server system, card access system panels, card readers, biometric readers, electric or magnetic locks, exit and emergency buttons, access turnstile systems, barrier systems, standalone readers and proximity cards .

As can be seen, all these systems are electrical or electronic systems. As with all electrical systems, it carries different risks in terms of electrical safety in various situations.

With the legal regulations and published standards, the health of human and domestic animals is protected and the property security is tried to be ensured. In this context, in order to avoid any short circuit or other risk, low voltage tests (LVD tests) of all safety devices, equipment and systems shall be performed in accordance with the provisions of the Regulation on Electrical Equipment Designed for Specific Voltage Limits (2014 / 35 / EU).
