VESDA VLP
VLP LaserPlus Aspirating Smoke Detector
The VESDA VLP detector is the central element of the VESDA ASD product range. Using unique detection principles, the VLP has an alarm sensitivity range of 0.005%20% obscuration/m (0.0015%6.25% obscuration/ft). The VLP is classed as a “Very Early Warning Smoke Detector”, which means that it detects fire 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
efficiency aspirator. Each inlet pipe has an airflow sensor that monitors
airflow 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-fine air filtration 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.
Verdant ™
VESDA detectors and devices communicate across Verdant, the VESDA fault
tolerant communications protocol. The Verdant 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 VESDA system.
Outlearn ™
The VLP technology employs unique software tools to ensure optimum operation
in many differing environments. Outlearn 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 fire 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.
