- Vesda VLC-505-EX Laser Compact Aspirating Smoke Detector has been specifically designed to provide all the benefits of aspirating smoke detection, including very early warning, for the protection of hazardous applications with Zone 2 classification. The VLC-EX is enclosed in a stainless steel housing which is comprised of the main enclosure and the front cover. The main enclosure houses all the key components of the detector. All non-serviceable items such as the main processor board and detector chamber are mounted away from the general access area, protecting them during the installation and servicing process.
