I am amazed at some of the posts on here, especially from the "anti FRS" mob 
In the absence of the fire risk assessment for the premises in question, how can we (royal) all have such vigorous opinions on how incompetent and wastefull of tax payers money?? etc..etc..etc the Fire & Rescue Service in question has been on this occassion?
Whilst conducting the fire safety audit there may have been other factors behind the decision to ask for S/D.
The determination has been very useful and informative and draws a line in the sand from which we can all move on but rather than criticising each other let us remember what I think was a ligitimate concern of the fire and rescue service in this case and which needed examination.
At the time of review of BS5839 part 1 in 2002 the principal focus was on the early detection of fire to ensure that the alarm was raised long before the escape routes become affected by fire or smoke. The longer it takes for the occupants of the building to respond and evacuate, the more comprehensive the need for detection to ensure a sufficiently early warning.
When the Fire Safety Order came into force in 2006 there was a new focus- the relevant person - and many people felt that perhaps the old 2002 standard did not give adequate protection to relevant persons in hotel bedrooms.
There was no empirical evidence to show that there was a problem, but as the new Order is so clear in applying the principles of protection many of us in the industry and in the enforcement agencies took the view that perhaps a person may be better protected if they are sleeping in a room fitted with a smoke detector rather than a heat detector.
There has been no research to justify this stance but it seems a reasonable premise to me. After all the BS5839 recommends rooms designed for use by disabled persons should be fitted with smoke detection to give them earlier warning of fire, as they take longer to respond. I also note the possible detrimental effect of more unwanted signals.
In an ideal world the fire authority could rally its forces and campaign for meeting of the various CFOA committees and this could lead to a call for a review by the BSI technical committee to review the standard but that would take forever.
The best way and quickest way forward is to use the determination process provided by the legislation, on condition that all parties are aware of the consequences and willing to see the process though to its conclusion. I believe this was the case in the recent determination and we all benefit from the clear guidance that resulted. We have a benchmark from which to work and I for one am grateful. It makes my job a lot easier, even if personally I disagree with the decision.
