Notifier View
The VIEW laser sensor uses an extremely bright laser diode, special lens and mirror optics to achieve sensitivity one hundred times greater than standard photoelectric technology!
A fully integrated, proven reliable system which pinpoints the fire location and is so advanced that it provides controlled stability, automatic drift compensation and adjustable alarm and pre-alarm settings; along with a full range of alarm and detection options

VESDA Products
VESDA works by continually drawing air into the pipe network via a high efficiency aspirator. A sample of this air is then passed through a dual stage filter.
The first stage removes dust and dirt from the air sample before it allows the sample to enter the laser detection chamber for smoke detection. The second (ultra fine) stage has a unique feature that provides an additional clean air supply to keep the optical surfaces within the detector clear from contamination. It also ensures stable calibration and a longer life for the detector.
From the filter, the air sample is passed through to the calibrated detection chamber where it is exposed to a stable controlled laser light source. When smoke is present, light is scattered within the detection chamber and is instantly identified by the highly sensitive receiver system. The signal is then processed and presented via bar graph display. The VESDA detectors are able to communicate this information to a fire alarm control panel software management system via relays of a High Level Interface (HLI).
Fire Chief Equipment Installs the following VESDA detection systems:
LaserSCANNER (protects areas up to 20,000 sq ft.)
The LaserSCANNER locates the origin of smoke by identifying the first sector (pipe) with the highest level of smoke and then continues to sample from all sectors to monitor fire growth. The LaserSCANNER also provides four alarm levels for each individual pipe (Alert, Action, Fire 1 and Fire 2) and provides individual pipe addressability and individual pipe settings.
LaserCOMPACT (protects areas up to 8,000 sq ft.)
The LaserCOMPACT offers a simple and cost effective solution for the protection of single and smaller environments that occupy less than 8,000 sq. ft. (800 sq. m). It offers the same wide sensitivity range as the LaserPLUS and LaserSCANNER – 0.0015 to 6% obs/ft (0.005 to 20% obs/m).
The LaserCOMPACT supports three configurable alarm levels: Alert, Pre-Alarm and Fire. It also comes in two versions: one version interfaces via relays only (RO) and the other version communicates across either relays or VESDAnet (VN).
LaserFOCUS (protects areas up to 5,000 sq ft.)
LaserFOCUS delivers the most advanced air sampling smoke detection technology to small environments in a very cost effective fashion.
It is available in two models; VLF-250 protects areas up to 2,500 sq.ft., while VLF-can guard areas up to 5,000 sq. ft.
