VESDA Overview

Real-time measurement of "current smoke concentration in the air" using a pipe network "Active" early detection of signs of fire Early detection of smoke.

VESDA Features

Optical Light Scattering detection method using laser (Absolute value detection of smoke)
System auto-configuration function (Autolearn)
World's highest sensitivity detection and maximum sensing range (0.00075 ~ 32% obs / m)
The world's largest event can be stored (18,000)
World's highest / maximum range fire alarm value (0.005-20% obs / m)
Automatic fault diagnosis
Dust filter using dual filter
The optical part is kept clean and no correction is required
Always detect air flow per pipe
VESDANET communication enables monitoring and control in any area
