The VESDA VLF-500 LaserFOCUS aspirating smoke detector is a compact aspirating fire detection system designed to provide very early warning smoke detection in small to medium environments. The detector continuously samples air through a pipe network and analyses it using laser-based smoke detection technology to identify smoke particles at extremely low concentrations.

The VESDA VLF-500 is designed to protect areas of up to 500 m², depending on pipe design and sampling hole configuration. Correct system design should always follow the VESDA VLF-500 installation manual and manufacturer guidelines.

The primary difference between the VESDA VLF-250 and VESDA VLF-500 is the size of the protected area.

• 
  VESDA VLF-250 – coverage up to 250 m²
  
• 
  VESDA VLF-500 – coverage up to 500 m²
  

Both models use LaserFOCUS aspirating smoke detection technology and provide very early warning fire detection.

The VESDA VLF-500 aspirating smoke detector draws air continuously through a sampling pipe and analyses it inside a laser detection chamber. This laser smoke detection technology allows the system to identify smoke particles long before visible smoke develops.

The VESDA VLF-500 is commonly used in environments where early fire detection is critical, including:

• 
  Server rooms and data infrastructure spaces
  
• 
  Electrical switch rooms
  
• 
  Telecommunications facilities
  
• 
  Control rooms and monitoring centres
  
• 
  Equipment cabinets and plant rooms
  

These environments benefit from very early warning aspirating smoke detection.

The VESDA VLF-500 manual, installation guide and product documentation are available from the manufacturer or via the documentation section on this page. These resources provide guidance on installation, pipe network design, configuration and commissioning.
