VESDA VSP-033 Laser Chamber Assembly for VLI Aspirating Smoke Detectors

The VESDA VSP-033 VLI Chamber Assembly is the core sensing component for the VESDA VLI (Very Large Industrial) aspirating smoke detector. The VLI series is unique because it is designed to protect industrial sites like mines, manufacturing plants, and waste treatment facilities where high levels of background dust are common.

Over years of operation in these extreme environments, the internal optical chamber may require replacement to ensure detection accuracy remains at peak levels. The VSP-033 allows facility managers to “refresh” their detector without replacing the entire unit. It features a sophisticated optical bench that differentiates between smoke and large dust particles, significantly reducing nuisance alarms. By using only genuine VSP-033 assemblies, you ensure that your fire life safety system remains compliant with local civil defense and international fire regulations.
