Good Afternoon,

I just wanted to provide some positive feedback on your team with specific regards to Emma Williams in Export Sales. I work for a Facilities Maintenance company that is based both in the UK and Ireland which as I’m sure you can imagine; especially in the current climate can be challenging when it comes to stock.

I first started using your site last year and since then have always been welcomed with the most efficient delivery and quick response on stock required for our FA Technician.

Nothing is ever too much trouble and I just wanted to forward this feedback on to yourselves so it was brought to your attention and more importantly to say thank you.

Kind Regards,

Ceri

Vesda VLS-204 LaserSCANNER Detector - Display Fitted, 7 Relays

Vesda VLS-204 LaserSCANNER Detector - Display Fitted, 7 Relays

Vesda Xtralis

Product Code: VLS-204

Please Contact Us for Price & Availability.

Contact Us

Please Note: This product has now been replaced by the VESDA-E VES range, the suggested alternative is the Vesda-E VES Aspirating Smoke Detector with 3.5” Display (VES-A10-P)

Vesda VLS-204 LaserSCANNER Detector With Two Blank Plates, A SCANNER Display Module & 7 Relays

The LaserSCANNER is similar to the standard LaserPLUS detector, but also includes a valve mechanism in the inlet manifold and software to control the airflow from the four VESDA sectors (pipes). This configuration enables a single VESDA zone to be divided into four separate sectors, for example, distinguishing between separate voids within a room or seperate cabinets within the same room.

The LaserSCANNER draws air from all sectors in use. If the smoke level reaches the Adaptive Scan Threshold, the LaserSCANNER quickly scans 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 designated as the First Alarm Sector (FAS). Once Fast Scan is completed and the FAS identified, the LaserSCANNER continues to closely monitor all four sectors (pipes) to monitor fire growth and maintain full protection of the area. 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 to ensure the optimum alarm thresholds are applied for each sector.

The LaserSCANNER display has a bar graph to indicate the overall smoke level, alarm threshold and fault indication. The bar graph displays the individual sector smoke levels during the scanning sequence. There is an extra LED to indicate that a First Alarm Sector (FAS) has been identified and an extra function to the Silence Button to allow for Manual Scan to be initiated. The LaserSCANNER display module can be mounted into the LaserSCANNER front cover or remotely into a 19in subrack or a Remote Box.


The LaserSCANNER detector can be fitted with a programmable 7 or 12 relay Termination card. The additional Relays on the 12 way Termination card may be assigned on a "per sector" basis. Relays may be mounted in a remote box or in a 19in subrack.

The LaserSCANNER has both the AutoLearnTM and Referencing software functions to ensure optimum operation in different environments and to eliminate the occurrence of nuisance alarms. AutoLearn monitors the ambient environment and sets the most appropriate alarm thresholds (Alert, Action, Fire 1, Fire 2) during the commissioning process. Referencing ensures external pollution to a protected environment does not interfere with the true smoke level being detected.
