Early fire detection in the server room
The VESDA VLF-500 smoke detector is designed to protect small, operationally critical areas of less than 500 m² in size. The fire detector works by constantly sucking in air samples through extraction openings in a pipe network. The air is filtered and then fed into a measuring chamber, where the presence of the smallest amounts of smoke is detected with the help of light scattering technology. The status information of the smoke detector is displayed to the consumer via the detector displays and transmitted via relays or optionally interface cards. The VLF can be easily installed and commissioned without any special interfaces or software tools.
Ultrasonic air flow sensing of the RAS
The ultrasonic air flow sensing system used in the VLF provides a reading of the flow rate of the air intake pipe. The system is insensitive to changes in air temperature and air pressure and it remains unaffected by possible impurities. The VLF 500 from Xtralis is the first air sampling smoke detector to use an ultrasonic flow method and is therefore unique in this field.
