I don't believe anyone wanting to learn the basics of fire alarm systems should start with Mr Todd's book ' A Guide To The BS Code 5839-1:2002'. This book doesn't cover the basics, but does provide explanations for the recommendations in the code.

I don't believe anyone should use BS5839, or any explanatory book about it, as their introduction to fire alarms.

There is much else to learn before an understanding of BS 5839 should be attempted.

However, I would say that anyone who knows the basics of fire alarm systems and has a fair understanding of BS5839-1: 2002 should then also read Mr Todd's book mentioned above. It is excellent in explaining why the BS recommendations are recommended! There is much to be learnt about the BS from the book and although it can, sometimes, be a bit of a difficult read, it is well worth the effort. I highly recommend it for everyone involved with fire alarm systems.

Are you on commission Wiz?

Joking aside what would you recommend to members who wish to increase their basic understanding, before going onto the Standard itself and Colin's book?

I'll always give credit where credit is due and that book is a worthwhile read for anyone who knows the basics of fire alarms and 5839.

At this moment in time there is nothing that I know of that covers all the basics and of use to someone pretty new to fire alarms.

In saying that I have, in the past, come across information on the internet which I have thought gives some good information about the basics. I don't remember anything that I thought covered it in the depth that was required but at least it was something. Unfortunately, I don't have these internet sites to hand but I will, when I get time, try to track some down again to pass them on to interested persons. In the meantime, I would suggest that people surf the net looking for relevant information and to visit the internet sites of manufacturers such as Apollo for more more information.

Prof

We have a copy here, as is said you need a pre-read of the basics before tackling.

Davo, surely the Professor knows enough about the basics of fire alarm systems and BS5839 to understand the book?
Don't underestimate him, the man is a legend in his own lunchtime!

Dr Wiz - Not the first time I have been described as a leg end.

And Davo you have me all wrong. When I am on a mission I am more likely to dress up as Bonnie. After all I have the figure for it rather than as a fat middleaged man in a stripey shirt  who covers his baldness with a beret.

Does anyone recognise below detector


Does BS 5839 pt 1 2002 cover cleaning to get dust out in clause 45?

It's an old Hochiki detector now obsolete I believe.

I don't recall clause 45 specifically saying that the smoke detector chambers should be cleaned but there are other references to the need for cleaning detectors particulary in harsh/dirty environments.

PS

You may get more response if you post this as a new topic.

You may also get more response to any technical questions regarding the kit itself if you try here

I think I've seen it before but I can't be sure of the manufacture. I'm veering towards thinking it is an older Hochiki detector.

BS5839 2002 +A2 2008 recommends that all automatic detectors are examined for damage and that they have not been painted.

There is no recommendation for cleaning since the possibility and practicality of this might vary with different manufacturer's products. BS couldn't cover them all and particularly those models that hadn't been developed at the time of BS publication.

Recommendations for cleaning would be covered by each manufacturer. Most manufacturers offer a cleaning and refurbishing serice although it is generally impractical to use this.

I now offer one of Wiz's top tips for fire alarm service companies totally free of charge!

Always clean the outside of each detector, even if nothing can be done with it's internals. This will have the effect of keeping the detectors looking almost brand new against the discolouration of the detector bases that will surely happen after a couple of years. This is a visual indication to your customer that they are getting something for their money.

Customer's normally cannot see what they are getting for the maintenance money they are paying. This is because when maintenence is carried out properly there is no general change. Everything remains the same! Only when no maintenance is carried out, and things start going wrong, does it become apparant why maintenence is cost-effective. Cleaning the outside of a detector costs virtually nothing but it is worth it's weight in gold in customer satisfaction.

I have dozens of these top-tips but you will have to pay to learn the rest when my book is published.
