How often should VESDA filters be changed?
every two years
It is recommended that the filter is replaced in the VESDA VLC, VLS, VLP and VLF every two years to maintain the operational integrity of the detector (you may want to consider replacing the filter more frequently if the detector is used in dusty or dirty conditions).
How do you clean a VESDA pipe?
To clean pipes, blow compressed air (400 KPa) from the detector end of the pipes. Any dust and dirt should be blown away from the detector. Another option is to use a device such as a vacuum cleaner to clean sample holes, capillary tubing and end caps.
What is a VESDA system and how does it work?
VESDA Systems are aspirating smoke detection used for early warning applications where response to a fire is critical. 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.
How does the VESDA system work?
VESDA works by continuously drawing air into a distributed pipe network via a high-efficiency aspirator. The air sample then passes through a dual-stage filter. From the filter, the air sample goes through the detection chamber where it is exposed to a laser light source.
What does Vesda stand for?
Very Early Smoke Detection Apparatus
VESDA (an abbreviation of Very Early Smoke Detection Apparatus) is a Very Early Warning Aspirating Smoke Detection solution.
What does VESDA stand for?
What is VESDA pipe?
The VESDA pipe range is based on pipework of a standard inside diameter (ID) of 3/4”. VESDA aspirating smoke detection is an early warning system that detects. fire in the incipient stages – before flames are visible – by detecting the. products of pre-combustion in the air around the area about to ignite.
Where is a VESDA system used?
VESDA-E VEA The detectors are suitable for protection of areas where pinpoint location of fire events is essential, thus providing ideal fire detection solutions for healthcare, offices, education, retail, prisons and electrical cabinets.
What is VESDA used for?
The VESDA system is a “very early warning aspirating smoke detection” and is designed to alarm you to the danger as soon as possible. The VESDA air sampling fire detection system detects invisible by-products of materials as they degrade during the precombustion stages of a developing fire.
What is VESDA pipework?
piping that constantly and efficiently carry air samples from protected zones. to highly sensitive detectors. VESDA Pipe and Fittings are part of an integrated system manufactured from specialty plastics designed for use with most aspirating smoke detection systems, the VESDA VLP system in particular.
Who makes VESDA?
Xtralis is a global leader and pioneer in life safety. We invented VESDA very early warning aspirating smoke detection (ASD), the world’s leading ASD brand.
What is VESDA pipe made of?
VESDA Aspirating Pipe and Fittings are produced in red ABS under a stringent quality control system approved to BS EN ISO 9001, EN54 – 20 and EN61386-1 Class 1131 ABS (Acrylonitrile Butadiene Styrene) is a robust polymer, which has the most suitable physical properties for aspirating detection, optimising performance …
What is the procedure for testing a VESDA?
Appendix 9: Procedure for Testing Very Early Smoke Detector Apparatus (VESDA) Aspiring Smoke Detectors 1.0 Purpose This document provides a procedure to conduct periodic testing of a fire-detection device required by NFPA 72 National Fire Alarm Code, 2019 Edition Table 220.127.116.11 Device 17(7), (d).
How to test a fire alarm system VESDA?
· Post the ‘Fire Alarm Systems Testing in Progress’ notification signs. 4.2 Invite the SOTR to witness the test. 4.3 Evacuate hazard area of unnecessary personnel. 4.4 Station a knowledgeable technician at the Fire Alarm Control Panel (FACP); disconnect the building audible alarms at the FACP.
How to check the airflow signal in VESDA?
If above or below 5, reset the airflow signal by pressing the ‘Enter’ button. 5.8.3 If an AirFlow restriction of over 2 segments exists, clean the sample piping network and replace the air filter. 5.9 LaserPLUS: 5.9.1 Check airflow using the VESDA LCD Programmer.
