What is Low Voltage?

Low voltage refers to electrical systems that operate at a voltage lower than the standard voltage used in buildings and homes, which is typically around 120-240 volts. These systems are used for a variety of purposes, including structured cabling, access control, video surveillance, fire alarms, and security systems.

Structured cabling refers to the organized and systematic way in which cables are installed and configured to support a variety of communication systems within a building or campus. This includes cables for data, voice, video, and other types of communication. Structured cabling systems are typically designed to support both current and future needs, making them a cost-effective solution for businesses and organizations.

Copper Cable

Copper cables are the most commonly used type of cable in structured cabling systems. They are made of copper wire and are coated in a protective sheath to protect them from damage. Copper cables are relatively inexpensive and are highly conductive, making them a reliable choice for transmitting data and communication signals.

Fiber Optic Cables

Fiber optic cables are another type of cable used in structured cabling systems. They are made of thin strands of glass or plastic and are used to transmit data and communication signals using light. Fiber optic cables are capable of transmitting data at much faster speeds than copper cables and are also less prone to interference. However, they are more expensive to install and maintain.

Access control systems are used to control and monitor access to a building or facility. These systems typically use low voltage electrical systems to power card readers, keypads, and other access control devices. Access control systems can be used to restrict access to certain areas or to track the movements of individuals within a building.

Video Surveillance

Video surveillance systems use cameras and other video recording devices to monitor and record activity within a building or facility. These systems are often used for security purposes, but they can also be used to monitor the performance of employees or to keep track of inventory. Like access control systems, video surveillance systems typically use low voltage electrical systems to power the cameras and other devices.

Fire Alarms

Fire alarms are an important part of any building’s safety system. These systems use sensors to detect the presence of smoke or heat and trigger an alarm to alert building occupants of a potential fire. Fire alarms are required by law in many buildings and are typically powered by low voltage electrical systems.

Security Systems

Security systems are used to protect a

building or facility from unauthorized access or other threats. These systems can include a variety of components, such as motion detectors, door and window sensors, and alarm panels. Like other low voltage systems, security systems are typically powered by a lower voltage than the standard voltage used in buildings and homes.

In conclusion, low voltage systems are an important part of modern building and facility management. These systems are used for a variety of purposes, including structured cabling, access control, video surveillance, fire alarms, and security systems. Copper and fiber optic cables are the most commonly used types of cables in structured cabling systems, while access control, video surveillance, fire alarms, and security systems all rely on low voltage electrical systems to power their various components.
