Xtralis VESDA VLP User manual

Xtralis VLP
®
The Xtralis VESDA VLP detector is the central element of the Xtralis VESDAASD
product range. Using unique detection principles, the VLP has an alarm sensitivity range
of 0.0015%–6.25% obscuration/ft (0.005%–20% obscuration/m). The VLP is classed as
a “Very Early Warning Smoke Detector”. This means that it detects re at the earliest
possible stage and reliably measures very low to extremely high concentrations of
smoke.
How It Works
Air is drawn into the VLP through a network of air sampling pipes by a high efciency
aspirator. Each inlet pipe has an airow sensor that monitors airow changes in the
pipes. Air is exhausted from the VLP and may be vented back into the protected zone.
Inside the VLP, a sample of air is passed into the laser detection chamber. Ultra-ne air
ltration provides very clean air to protect the optical surfaces inside the detector from
contamination.
The detection chamber uses a stable Class 1 laser light source and carefully positioned
sensors to achieve the optimum response to a vast range of smoke types.
The status of the detector, and all alarm, service and fault events, are transmitted to
displays and external systems via VESDAnet.
VESDAnet™
Xtralis VESDA detectors and devices communicate across VESDAnet, the Xtralis
VESDA fault-tolerant communications protocol. The VESDAnet loop provides a robust
bi-directional communication network between devices, even allowing continued
operation during single point wiring failures. It also allows for system programming from
a single location and forms the basis of the modular nature of the Xtralis VESDA system.
AutoLearn™
VLP technology employs unique software tools to ensure optimum operation in many
differing environments.AutoLearn monitors the ambient environment and sets the most
appropriate alarm thresholds (Alert, Action, Fire1, Fire2) during the commissioning
process to allow the earliest possible warning of a potential re situation with reduced
nuisance alarms.
Referencing
Environments that employ air handling systems may be affected by pollution external
to the controlled environment when “fresh air make up” is added. Referencing by the
VLP ensures that external pollution does not interfere with the true smoke level being
detected in the protected environment. The system can safely compensate for this
transient state and allow continued operation free from such nuisance alarms.
