Why VESDA Smoke Detection?

With its heritage tried and tested in the specialist fire detection industry, VESDA is now recognised as the trusted benchmark throughout the business for all air sampling, smoke detection and fire detection purposes.

FSL recommend and install the entire VESDA product range as well as being able to supply the entire range and accessories to trade clients and individual customers. Our services include a full area risk assessment, system design, system installation, as well as an excellent back-up service for system maintenance and training.

In addition to all of this FSL have also designed and now manufacture its’ own high grade ABS piping and fittings to ensure the very best protection within the industry, for your assets and  your business

Traditional smoke detection systems have the drawback of having to be strategically, and often inconveniently (sometimes incorrectly!) located to maximise their effectiveness.

VESDA control boxes can be located in easy to reach positions The associated network of FSL ABS pipe work is structured to comprehensively sample air right throughout any given risk areas. All of this alleviates disruption to your business and makes for high safety and lost cost.

VESDA detection for warehouses                                

VESDA smoke detection is a suitable replacement for conventional smoke detection where accessibility is limited. For example, VESDA detection will be better suited to a warehouse with smoke detectors situated at high levels. Conventional smoke detectors can become faulty and access equipment will need to be deployed, this can be extremely disruptive to operation and it is also dangerous. VESDA smoke detection eliminates this issue as the aspirating pipe work will be located at high levels and the VESDA detector will be located at accessible levels. Aspirating pipe will replace the smoke detectors at high level, with holes in the aspirating pipe replacing the smoke detectors. VESDA smoke detectors have 18000 events log memory. Smoke levels can be tracked and identified against time and density. Commissioning VESDA should include measure smoke tests. There are different tests for different applications, these are measure with a set amount of smoke and readings from the VESDA detectors tell us how the system will perform in a real life situation!

VESDA detection for cold rooms

VESDA smoke detection is commonly used where temperatures are not suitable for other types of smoke detection. For example, a cold room operating temperatures ranging from 20’C to -20’C is an ideal environment for VESDA smoke detection. Cold temperatures will ice up the optical chambers of conventional smoke detectors rendering the system useless. VESDA detectors are located outside the cold environment, with aspirating pipe work located within the risk or outside the risk with capillary smoke sampling heads located within the risk! The cold air is then drawn to the VESDA smoke detector and is naturally heated before it arrives at the VESDA laser chamber. The condensation is collected at a condensate water trap and dry air arrives for sampling by the VESDA detector. In extreme cases air dryers may be needed, but in the most, are not required for the VESDA system!

VESDA detection for computer rooms

VESDA detection is ideal for area that have high airflow. Conventional smoke detectors struggle to activate with volumous air passing through their chambers. VESDA detectors draw smoke from the aspirating pipe and the holes in the pipe collectively capture the air and draw it back to the VESDA detector. Fire Suppression Limited have conducted test which conclusively prove that VESDA smoke detection is far more responsive than conventional smoke detectors. Measured tests again provide reports and samples of how the VESDA detectors will operate in a high airflow environment.

VESDA detection for Fire Suppression environments

VESDA detection with Fire Suppression is a fantastic combination. With ever increasing environmental responsibilities, it is essential that a fire suppression system should deploy unnecessarily. VESDA smoke detection use in conjunction with conventional smoke detection is a perfect match. Preferably VESDA detection samples the air across the return plenums of the air conditioning systems which provide primary smoke detection! An alert alarm can be raised and human intervention can prevent the gas from discharging! VESDA can also be used as a double knock system, which provides the most suitable fire detection model for any automatic fire suppression system!

 VESDA smoke detection for Ceiling voids

 With the recommendations of the BS5839 that stipulates that any ceiling void over 800mm in depth must be treated as the area below. With today’s modern architecture, many ceiling are solid ceiling with little access. VESDA smoke detection is ideal for this, as the aspirating pipe work will replace the conventional smoke detection, with the VESDA smoke detector in an accessible location.

VESDA smoke detection in lift shafts

VESDA smoke detection for lift shafts enhanced that smoke detection within what is a high sensitive area. It also makes maintenance safe as the engineer will not need to get into the lift shaft for maintenance purposes.
