Low Voltage Systems, also known as Limited Energy Systems, operate on electricity below 98V (typically less than 50V). These systems are designed to power essential building technologies that enhance safety, security, communication, and overall efficiency—while keeping installation and maintenance safer and more cost-effective than traditional high-voltage wiring.

Typical examples of low voltage applications include structured cabling for voice, data, and networking; surveillance cameras (CCTV/IP systems) along with security sensors and alarms; and access control solutions such as card readers and electronic locks. They also support intercoms and communication panels, audio/visual equipment like speakers and projectors, and commercial safety systems such as emergency shutoffs and monitoring. In addition, many modern buildings rely on low voltage systems for automation and control features, including lighting control and energy management.

They provide critical infrastructure for safety, communication, and security without the higher risks and costs associated with high-voltage systems. From fire alarms to access control, they help protect property, staff, and visitors while supporting day-to-day operations.

Security systems can include CCTV cameras, intrusion detection sensors, and access control technologies. These tools help monitor activity, prevent unauthorized entry, and provide peace of mind through real-time or recorded surveillance.

Yes. Intercoms, paging systems, nurse call solutions, and mass notification systems make it easier to deliver messages quickly across facilities, which is especially critical in healthcare, education, and large commercial environments.

Low voltage devices can run on structured cabling systems (copper, fiber, coaxial) for stable connections or wireless solutions when cabling isn’t practical. Both options support CCTV, access control, and audio-visual integration.

Yes. Since they operate below 50 volts, low voltage systems carry a lower risk of electrical shock. This makes them safer to install, operate, and maintain compared to traditional high-voltage wiring.

Mass notification systems and fire alarms provide fast alerts in emergencies. Nurse call systems in healthcare also ensure staff receive critical information instantly, which can save lives.
