Firgure1: VESDA product line
Vesda Early Warning System is one of the early warning systems that can cause a fire. The sensitivity and ability to accurately identify fire addresses as well as make early announcements outperform traditional machines.
Appropriate protection for areas where the potential for fire is accurately determined as soon as possible. Provides applications for health facilities, offices, prisons, electrical cabinets, chemical areas, laboratories, power stations ... A range of features that provide flexibility, programming capabilities, enhanced connectivity and reduce the total cost of use.
The Vesda system is a highly sensitive smoke detection system, distributed in areas where smoke is detected, such as false ceilings, in rooms, under technical floors or in electrical cabinets, etc. through air filters. most accurate analytical sample. Brings the highest safety for users.
VESDA devices communicate on VESDAnet, providing a robust two-way communication network that allows continued backup operations even during single-point wiring errors. VESDAnet allows key reporting, central configuration, control, maintenance and monitoring. VESDA probes can communicate with fire control cabinets, software management systems or building management systems via relays, or a special communication device.
Firgure2: VESDA diagram
VESDA works by continuously sampling air into the piping system thanks to a high efficiency exhaust fan. This air sample is then passed to a double layer filter. The first layer separates dust and dirty air before the air sample enters the laser probe to analyze smoke levels. The second layer provides more clean air, keeping the optical surface of the probe from being dirty and ensuring the device operates stably and prolongs the service life. From the filter, air samples pass through the analyzer with a laser light shining through. When smoke is present, the light shining in the detector chamber immediately recognizes it by the highly sensitive receiver. The signal is then processed and displayed by signal lights, external warning devices.
Firgure3: VESDA Network
The VESDA-E VEA series early warning system combines VESDA reliability and early warning with the ability to determine the exact address and a range of notification options that truly surpass traditional machines. Use air sampling points and microbore air sampling points with three alarm sensitivity settings for the sampling points. As a multi-channel addressable system, the VEA detector can divide a protected space into sampling locations, allowing localization of potential fire sources for faster incident response. . The VEA is suitable for protecting areas where precise fire potential is to be determined, thus providing ideal fire detection solutions for health facilities, offices, education, retail, prisons and cabinets. electricity. A range of features that provide flexibility, programming capabilities, enhanced connectivity and reduced total usage costs.
VESDA -E-VEP smoke detectors are equipped with the latest and most advanced smoke detectors to provide very early warning and the best counterfeit smoke detector for many applications. Built upon Flair detection technology and years of applied experience, VEP probes get stable operation over their lifetime through absolute calibration. In addition, VEP offers a range of revolutionary features to the value of the user.
VEU series early warning system is a high-end VESDA-E series detector. Ultra wide sensitivity range; 15 times larger than VESDA VLP and providing more sampling holes and increased coverage in high airflow applications by up to 40%. Significantly longer linear pipes and extended branch network configurations are perfect for high ceiling applications that increase coverage by up to 80% while allowing convenient detector installation for easy warranty. and maintenance. A series of revolutionary new features that provide outstanding detection performance, flexibility, wide programming capabilities, connectivity and reduced total cost during use.
VESDA-E VES is similar to the leading VESDA-E VEP but includes a valve mechanism in the air duct and software to control airflow from four tubes (tubes). This configuration allows a single area to be divided into four distinct areas, for example, distinguishing between separate aisles in a data room. VES allows users to locate smoke sources by identifying the first area that reaches the Warning level. The detector then continues to sample from all areas to monitor the development of the fire and will report individual alarm levels for each area. VES provides four individually configurable alarm levels (Alarm, Action, Fire 1, Fire 2) for each zone for optimal protection. Built on Flair detection technology and years of applied experience, VES detectors achieve stable performance throughout their lifetime through absolute calibration. In addition, VES offers a range of revolutionary features that provide user value.
The VESDA VLF-250 detector is a very early warning smoke detector designed to protect small, important business areas of less than 250 m2 or 500 m2.
The detector works by continuously drawing air into the sampling holes in the pipe network. The air is filtered and fed into the detection chamber where light scattering technology detects the presence of a very small amount of smoke. Detector status information is communicated on the detector screen and via an optional relay or interface card.
VLF can be installed and put to use without special interfaces or software programming tools. Ultrasonic airflow sensor.
