Extra-Low Voltage Systems
Extra-Low Voltage (ELV) systems typically operate below 50 V AC or 120 V DC (ripple-free), posing minimal risk of electric shock compared to higher voltage systems. They offer safety and flexibility in various building applications, including:
Security and Access Control:
• CCTV Systems: Monitor activity and deter crimes.
• Access Control Systems: Manage entry and movement of people.
• Intruder Detection Systems: Detect unauthorized entry attempts.
Fire Safety and Life Safety:
• Fire Alarm and Smoke Detection Systems: Alert occupants to potential fires.
• Public Address Systems: Provide emergency instructions and evacuation guidance.
• Water Leak Detection Systems: Detect and alert about water leaks to prevent damage.
Communication and Information:
• Audio Visual Systems: Enhance presentations, meetings, and events.
• IT and Networking Systems (Partially): Connect devices and enable data communication (certain components might use higher voltages).
Building Management and Automation:
• Lighting Control Systems: Adjust lighting levels for energy efficiency and comfort.
• Building Automation Systems: Integrate and control various building functions for increased efficiency and sustainability.
