BS 5839 states that during routine servicing ;
""The fire alarm functions of the control and indicating equipment should be checked by the operation of
at least one detector or manual call point on each circuit.
The cause and effect programme should be confirmed as being correct.""
Don't you think both of those, relate to, if a detector activates, it should provide the correct information at the panel ?
...........................
AFD, those items from the BS are still not categorically and clearly recommending that a service engineer checks that a detector is located in the 'correct' zone. If they were meant to, I believe it would clearly say such. By the time that servicing is carried out on a system, the implication of the recommendations of BS are that this type of thing has already been correctly designed by the designer and that the actual installation has been checked by the commissioner.
The BS recommendation of the testing of a device per circuit is really only testing that each panel circuit does what it is meant to do, and not that every detection device is in the 'correct' fire zone
The recommendation for checking 'cause and effect' relates to only to programmable systems and is really only in respect of checking that those variable programmable functions have not altered. I accept that zone allocations are programmable on some panels, and it could therefore be argued that these should be checked on such a panel as a C&E, but you still wouldn't have to check them on a non-programmable panel and I think the BS is more concerned about output relays etc. functioning when they should rather than zone indicators not working (which in the whole scheme of things is a minor problem).
I accept that a good fire alarm engineer should be perfectly capable of being able to check the installation of devices to the correct zone allocations, but BS clearly doesn't ask a service engineer to do this.
Obviously, I am only considering BS recommendations. If the customer has specifically asked for this (or anything else) as part of the servicing routine, then it should be carried out.
Most companies provide, and most customers want, 'Servicing to BS recommendations'. Why do something over and above the precise requirements of BS? If you want to be competitive, it is no good doing more than the contracted requirements. You won't get paid any extra, and you won't be thanked for doing it. You'll just be wasting your time.
Service engineers are there to check that the components of the system are working in the manner they are intended to, and not there to continually re-check things that should have been correct from the beginning and, theoretically, cannot be accidentally changed (unless someone has subsequently made a cock-up!)
