A Guide to Extra-Low Voltage (ELV) Systems

Extra-Low Voltage (ELV) Systems

Extra-Low Voltage (ELV) refers to a voltage below 50 volts AC or 120 volts DC. ELV systems are used in telecommunications, security, and lighting. Components of ELV systems may include power supplies, transfer Components, relays, and control devices.

Best Known Uses for ELV Systems in Dubai

  • Closed Circuit Television System (CCTV)

A Closed Circuit Television System (CCTV) is a video surveillance system where cameras are connected to a private network to transmit visual footage to a limited group of monitors. This system is commonly used for security in public areas, businesses, and homes.

  • Access Control System – ACS

An Access Control System (ACS) is a security system that controls and manages access to physical or logical resources. It helps to restrict access to authorized personnel and to enhance security in various settings such as buildings, rooms, computer systems, and networks. 

  • Public Address and General Alarm System – PAGA

A Public Address and General Alarm System (PAGA) is a communication system. Nonetheless industrial facilities like marine vessels to broadcast announcements, alarms, and instructions to personnel in an emergency or during routine operations are using PAGA.. It typically involves a network of speakers and microphones connected to a control room, allowing for centralized management. 

  • LAN and Telephone Systems

LAN (Local Area Network) and Telephone Systems are communication technologies. Basically LAN refers to a computer network that connects devices in a limited geographical area, such as an office or building. Telephone systems are used for voice communication over a distance using a network of telephone lines. 

  • Trunk Radio System – TRS

Trunk Radio Systems (TRS) are types of two-way radio communication systems that automatically assign frequencies to users based on the availability of channels. This allows for more efficient use of available frequencies and can reduce interference.  Public safety organizations, transportation companies, and other large groups that require reliable and coordinated communication are using TRS.

  • Master Clock System – MCS

The Master Clock System (MCS) is a centralized system that synchronizes all clocks and time-based devices within a building or facility to a single, accurate time source. This ensures that all clocks throughout the building display the same time for efficiency and precision in various operations.


In conclusion, Extra-Low Voltage (ELV) systems provide safe and reliable power to low-power devices. These systems use voltage levels below 50 volts. We can use for communication, lighting, and control systems. ELV systems helps to minimize the risk of electrical shock and comply with safety standards. Eventually, ELV systems play consequently a critical role in modern buildings and infrastructure.
