VESDA LaserPLUS Overview

The LaserPLUS is the core product in the VESDA product range. Like all VESDA products it detects fires at the earliest possible stage and reliably measures very low to extremely high concentrations of smoke. It has the worlds widest sensitivity range of 0.005 to 20% obs/m. VESDA LaserPLUS supports four configurable alarms (Alert, Action, Fire 1 and Fire 2) and protects areas up to 2000 sq/m.

How It Works

Air is drawn into the LaserPLUS through a network of air sampling pipes by a high efficiency aspirator. Each inlet pipe has an airflow sensor that monitors airflow changes in the pipes. Air is exhausted from the LaserPLUS and may be vented back into the protected zone.

Inside the LaserPLUS, a sample of air is passed into the laser detection chamber via a dual-stage air filter. The first filtration stage removes dust and dirt from the air sample before entering the laser detection chamber for analysis. The second stage provides ultra fine air filtration to provide very clean air that is used to protect the optical surfaces inside the detector from contamination.

The detection chamber uses a stable Class 1 laser light source and carefully positioned sensors to achieve the optimum response to a vast range of smoke types.

The status of the detector, and all alarm, service and fault events, are transmitted to displays and external systems via VESDAnet.
