Very sensitive smoke detector for small area 250m2, 500m2 VESDA VLF

Product Features

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.

    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.

  • Very sensitive smoke detector VESDA-E-VES

    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.
