Unprecedented Event Identification with the Revolutionary Instant Recognition Display
The VESDA LaserFOCUS has been equipped with a clear, intuitive, circular ‘smoke dial’
display that allows for immediate risk assessment and preventative action. When
illuminated, the well positioned LEDs and related icons allow for instant identification of smoke growth and alarm conditions, even from a distance.

Immediate Analysis and Diagnostics with the Instant Fault Finder™
To ensure ongoing system integrity, immediate
assessment of the detector’s condition is critical. By
opening the .eld service access door, the operator can
activate the Instant Fault Finder feature - a smart diagnostic
feature that converts the ‘smoke dial’ into a fault indicator. It provides
instant and meaningful information of the detector’s status without the need
for additional programming and evaluation tools. Now .re service and maintenance staff can be
better informed before arriving onsite, reducing the time onsite, and saving on maintenance costs.

With the VESDA Pipe Network being such an integral part of any VESDA Air Sampling
System, maintaining its integrity and reliability is critical in ensuring a consistently
accurate level of detection performance. The VESDA LaserFOCUS utilises
Ultrasonic Flow Sensing principles to assist in the measurement & monitoring
of airflow. The VESDA LaserFOCUS detector immediately identifies and
communicates any variances in the airflow rate.

Reliable Air Flow Monitoring using Ultrasonic Sensing
With the VESDA Pipe Network being such an integral part of any VESDA Air Sampling
System, maintaining its integrity and reliability is critical in ensuring a consistently
accurate level of detection performance. The VESDA LaserFOCUS utilises
Ultrasonic Flow Sensing principles to assist in the measurement & monitoring
of airflow. The VESDA LaserFOCUS detector immediately identifies and
communicates any variances in the airflow rate.

In this application, the ultrasonic .ow sensing technology was adapted to monitor air rather than liquids. Two transducers (Blue) are used to continually send signals to each other. One signal travels with the flow (Violet), the other against (Yellow). The time difference between the two signals is used to calculate the rate of airfow within the pipe.

Supporting Efficient System Setup - AutoLearn™
Simplifying the setup, installation and commissioning of high sensitivity air sampling technology was one of
the key drivers behind the design of the VESDA LaserFOCUS. VESDA’s AutoLearn feature supports this
process by assessing environmental conditions, automatically setting acceptable smoke alarm and flow fault
thresholds.

Simplifying Pipe Network Design
To simplify the application of air sampling detection the LaserFOCUS is supplied with pre-engineered pipe network designs. Designers can simply apply these proven designs to typical installations and have confidence that they will work.

Intelligent Software Support VSC™ and ASPIRE2™
VESDA LaserFOCUS is supported by the next generation of VESDA intelligent software packages. The VESDA System Configurator Software (VSC) offers a high level of programming flexibility through its on-line and off-line configuration capabilities. Rapid diagnostic abilities, concurrent configuration views, and multi device smoke trending are additional features designed to simplify system design.
Complementing VSC, ASPIRE2 speeds up and simplifies the design of new and more complex pipe network layouts. Key features such as design wizards, isometric views, an automated design verification process, and improved AutoBalance capabilities ensure that a tailored pipe layout is easy to achieve.
Both VSC and ASPIRE2 are backwards compatible with the VESDA Laser-based detector family.
