Xtralis VESDA VLS-314 LaserSCANNER Air Sampling Smoke Detector Unit

Feature & Principle

The built-in fan draws air samples from four sampling pipe sectors. When smoke is detected, the unit automatically scans each channel to locate the smoke sector. It uses laser light scattering principle to detect ultra-low smoke concentration at the early fire stage, sends alarm and fault signals via relay contacts to fire alarm host.
