I have to admit that I advised on installing VSD on a particularly difficult specialist technical building where I was struggling to find a suitable detection system and its been a near disaster. I am not saying VSD is not effective, but I have introduced various innovative fire safety solutions before they've had a British Standard (water mist & hypoxic being two), and this is the final straw. I will wait until there's a BS before I will revisit this kit

I cannot go into details due to customer confidentiality etc, but the building features a number of wide open areas that were subject to smoke. The open spaces can get very dirty and acts as a very large access room with numerous inner rooms, some containing up to 50 people.

VESDA may have been appropriate, but single point detection was not possible due to the likelihood of fumes. Heat detection of course is not suitable for protecting those within an inner room

The VSD system was installed and we had problems from the start. All the marketing promises were worthless and variable light levels caused huge issues. For example, low but bright winter sun suddenly shining from an open door into the darker access room caused numerous unwanted fire signals.

Now, about 5 years later, we still haven't commissioned it and never will. The VSD is not connected to the fire detection system, but runs parallel to it. We use the VSD to start a staff search - so we are protecting those within the inner room, but not in the way we expected.

I wish we had gone with VESDA now

I will e-mail you with a few more details that I can't discuss here

Video fire detection was added to the BS5839 Part 1 2017, only in small sections but its a start and no doubt will evolve moving forward....

I do have issues with the British Standards Institute

They take a stupid amount of time keeping up with innovation - something that has the potential to cause a great deal of harm when people have to wing it by adjusting other standards. I have been in projects installing video detection and hypoxic air systems and had to work blind with no standard.

And then when they are published, they are ridiculously priced for the SME and one-man bands. Especially when you consider in the US, the NFPA often supply their standards free of charge
