VESDA by Xtralis Introduction to the VESDA System Design Manual Introduction to Obscuration Smoke obscuration is the effect of smoke on visibility. It is the most widely accepted measure for expressing the concentration of smoke and refers to the percentage of light that is blocked, or obscured over a specified length (meter/foot).

If smoke is detected it is reported through the CPU card to the display assigned to the detector. Presence of smoke can also be displayed on a LCD Programmer or through Xtralis VSC Software. The detector can be configured to raise alarms at different levels and/or report events through a Fire Alarm Control Panel (FACP).
Systems. The software allows control of detectors and devices connected to the system. It can be downloaded from the partner extranet at www.xtralis.com. Xtralis VSM4 is an optional software package that provides the ability to monitor multiple remote sites with full control and programming functionality. Refer to www.xtralis.com or contact your authorized representative for further information.
VESDA by Xtralis Connecting Xtralis Systems to External Systems The VESDA System can be integrated to external Fire Alarm Control Panels and other building management systems to raise pre-alarm and alarm conditions, action automatic emergency procedures, and shut down ventilation systems. It can also be integrated into an automatic fire suppressant release system.
