Vesda Smoke Detection- Aspirating Smoke Detection- Wired Smoke Detector

Vesda Smoke Detection- Aspirating Smoke Detection- Wired Smoke Detector- distributed by Koetter Fire Protection - Dallas, Texas

Vesda Early Warning Smoke Detection

A fire detection system that offers the earliest possible warning of a potential fire.

A system that will ensure business continuity and freedom from nuisance alarms. A system that can adapt to the ‘unique’ characteristics of any given environment.

One that delivers high performance through its high quality design and its dedicated global sales and distribution channels.

With over 50,000 units installed worldwide, the VESDA name has become synonymous with high performance very early warning smoke detection. It is the product chosen when reliable performance is crucial.


How VESDA Works

This diagram shows the progression of fire growth over time. Note that the incipient stage of a fire provides the widest window of opportunity to detect and control the spread of fire. VESDA can be configured to generate multiple alarms within the incipient stage. VESDA can also be configured to generate an additional alarm (Fire 2) in the advanced stages of a fire. This feature is unique to VESDA and takes advantage of its very wide sensitivity range; thus allowing one detector to monitor the entire progression of fire growth.

VESDA aspirating smoke detection 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 the unique feature of providing an additional clean air supply to keep the optical surfaces within the detector clear from contamination and to ensure the stable calibration and long life of 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 a bar graph display, alarm threshold indicators and/or graphic display. The VESDA detectors are able to communicate this information to a fire alarm control panel, a software management system or a building management system via relays or a High Level Interface (HLI).

VESDA Product Range

LaserPLUS

The LaserPLUS detector is the core product in the VESDA product range. Like all the VESDA products it detects fire at the earliest possible stage and reliably measures very low to extremely high concentrations of smoke. It has the world’s widest sensitivity range of 0.0015 to 6% obs/ft (0.005 to 20% obs/meter). The LaserPLUS display supports four configurable alarms (Alert, Action, Fire 1 & Fire 2) and protects areas up to 20,000 sq.ft. (2000 sq.m).

LaserSCANNER

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. It protects areas up to 20,000 sq.ft./5000 sq.ft per sector (2000 sq.m/500 sq.m per sector).

LaserCOMPACT

The LaserCOMPACT offers a simple, cost effective solution for the protection of single and smaller environments that occupy less than 5000 sq.ft (500 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, Fire) and comes in two versions. One version interfaces via relays only (RO), and the other across either relays or VESDAnet (VN).

Remote Displays and Programmers

The VESDA display module monitors and reports the status of a detector. It gives visual representation of smoke levels along with all alarm and fault conditions. For monitoring convenience, multiple displays can be associated with a single detector.

The VESDA programmer is menu driven and allows the user to conveniently configure, commission and maintain their VESDA system, as well as program each individual detector. Only one programmer is needed to support the entire network.

Display and programmer modules can be mounted in a detector unit, separately (connected via VESDAnet) in a single remote mounting box or in a 19" sub rack. A hinged, glass-front sub rack enclosure is also available for mounting up to three sub racks.

VESDA Pipe

One of the key elements in the performance of a VESDA aspirating detection system is the network of sampling pipes that actively transport air from a protected area to the detector. This is why VESDA offers a CPVC, Aspirating Pipe and Fittings package that is UL1887 listed for use in Plenum rated areas. VESDA Pipe will simplify pipe selection and ensure that a quality system is installed every time.


VESDAnet

VESDAnet is a comprehensive fault tolerant "closed" 2-wire communications loop. It links the detectors, displays, programmers and remote units on a daisy chained loop in a configuration that meets customer requirements. VESDAnet allows for a number of units to be programmed together from one or more locations and automatically detects communication failures.

It also allows for easy interfacing with systems external to the network such as intelligent fire alarm panels and building management systems.

VESDA Software VSM

The VESDA System Management software package allows the user to monitor, configure and control a VESDA system from a central location via a VESDAnet communication loop. Real time and historical events for a single detector, an area, or the entire facility can be collected, processed and presented in either report or graphical format.

VConfig

VConfig is a configuration tool specifically designed to simplify the setup of any VESDA system during commissioning and installation. It is available via a PC Link HLI (High Level Interface) into VESDAnet or directly to a LaserCOMPACT using VESDAlink.

ASPIRE

ASPIRE is a computer software tool for designing and evaluating aspirated pipe system layouts. By simply entering parameters such as pipe length, the number of pipes in use, air temperature, pressure and the type of detector(s) used, the software can calculate a pipe sampling model that will predict the performance of the proposed pipe network.
