Wormald install VESDA systems/detectors at Stanwell Power Station

Supplier News

Stanwell Power Station have installed 10 new laser scanners, incorporating the Very Early Smoke Detection Apparatus (VESDA) system, a high performance system which adapts to the unique characteristics of its environment.

Wormald  installed the VESDA systems/detectors that work by continuously drawing air into the pipe network through a high efficiency aspirator. A sample of this air is then passed through a dual stage filter, the first stage removing dust and dirt and the second stage providing an additional clean air supply to keep the detector’s optical surfaces free from contamination.

From the dual stage filter, the air sample is passed through to a calibrated detection chamber, where it is exposed to a laser light source. If smoke is present, light is scattered within the detection chamber and is immediately identified by the sensitive receiver system.

The signal is then processed and presented through a graphic display or alarm threshold indicators. The VESDA systems/detectors communicate this information to a fire alarm control panel, a software management system or a building management system through relays or a High Level Interface (HLI).

The VESDA systems/detectors at the Stanwell Power Station are installed in key areas including the computer relay rooms, station relay rooms, coal bunkers, reclaim tunnels and the power station’s uninterrupted power supply (UPS) rooms.

According to Stanwell Power Station, the VESDA systems/detectors are sensitive, providing them with the prompt warning needed to identify the location of a fire and then quickly and efficiently react to it in order to protect the systems and prevent a shut down.
