At the new Abu Dhabi International Airport Midfield Terminal Building (MTB), due to open in 2017, Xtralis VESDA VLS aspirating smoke detectors will be installed for fire prevention.
The MTB will be the emirate’s largest terminal. Xtralis says that its VESDA and VESDA-E aspirating smoke detectors (ASD) now protect many of the United Arab Emirates super structures, including the Burj Khalifa, Emirates Palace Hotel, and airports.
The new Midfield Terminal Complex (MTC) will have 700,000 sq m of internal for passengers, cargo, and restaurants and retail.
As the MTB have such massive open spaces, where smoke will be diluted, an effect compounded by air-conditioning systems, the airport required early and reliable detection. Also, temperatures in the terminal could range from hot to cold, depending on weather, and according to the product company VESDA was the only detector that could ensure early and reliable detection under these conditions.
The VESDA LaserScanner (VLS), pictured, is similar to the VESDA LaserPlus (VLP) detector, but includes a valve mechanism in the inlet manifold and software to control the airflow from the four sectors (pipes). This configuration enables a single zone to be divided into four separate sectors, for example, distinguishing between separate voids within a room. The VLS draws air from all sectors in use. If the smoke level reaches the Adaptive Scan Threshold, the VLS performs a ‘Fast Scan’ of each pipe to identify which pipe is carrying smoke. If more than one pipe is transporting smoke, the sector with the highest smoke concentration is scanned first. Once the scan is completed and the sector with the highest smoke concentration is identified, the VLS continues to monitor all four sectors (pipes) to monitor fire growth. There are four alarm levels (Alert, Action, Fire 1 and Fire 2) for each sector (pipe) and the sensitivity for each alarm level can be set. Visit www.xtralis.com/VESDA.
