ELV Systems

ELV systems (Extra Low Voltage Systems) refer to a range of electrical systems that operate at voltages considered safe and typically below 50V AC or 120V DC. These systems are widely used in modern buildings and infrastructures due to their safety and efficiency in various applications. Here are some of the most common types of ELV systems:

 

Here are the key components and features of ELV Systems:

1. CCTV Surveillance

High-definition camera systems for 24/7 security monitoring

  • Control: Mobile app / NVR / Web Portal

  • Features: Motion detection, night vision, cloud storage.

  • Examples: Philips Hue, LIFX bulbs.

  

 

 

2. Access Control Systems

Control who enters or exits specific areas using biometric or RFID access
  • Control: Central software / Mobile app

  • Features: Logs access, time scheduling, real-time alerts

  • Examples: Offices, data centers, hotels

  
 

3. IP Intercom Systems

Audio-video communication between entry points and internal rooms.

  • Control: Indoor monitor / Mobile app

  • Features: Two-way video/audio, call history, door release.

  • Examples: Villas, apartment buildings, clinics.

  
 

4. Public Address Systems (PA)

Speaker systems for announcements and background audio.

  • Control: Wall controller / Central console

  • Features: Zone control, pre-recorded messages, volume adjustment.

  • Examples: Malls, schools, offices.

  
 

5. Structured Cabling

network cabling for data, voice, and system connectivity.

  • Control: Passive infrastructure

  • Features: High bandwidth, easy troubleshooting, future scalability

  • Examples: Office networks, hotels, control rooms.

  
 

6. SMATV / IPTV Systems

Distribute satellite or digital TV signals to multiple units

  • Control: Central headend unit

  • Features: HD/4K quality, channel grouping, integration with smart TVs.

  • Examples: Hotels, apartments, lounges.

  

7. Fire Alarm Systems

Early detection of fire via smoke and heat sensors

  • Control: Fire alarm control panel

  • Features: Auto alerts, sirens, emergency integration.

  • Examples: Schools, hospitals, warehouses.

 

Benefits of ELV Systems:

  • Safety: Operating at low voltages reduces the risk of electrical shock and fire hazards.
  • Energy Efficiency: These systems are generally low power-consuming, making them cost-effective to run.
  • Reliability: ELV systems are highly reliable and are designed to function in critical situations, such as during emergencies.
  • Easy Integration: ELV systems can be integrated into a central control system, allowing for more streamlined building management.
