The Intruder Alarm Report 2020

Landmark false fire alarm study to spawn a sequel

A new European standard could be proposed as a means to tackle false fire alarms as a fire systems trade body announces plans to reopen a landmark study into the issue.

In the summer of 2018 Euralarm’s fire section published the findings of the exhaustive study, which explored the multiple causes of a problem that costs the London Fire Brigade alone £37m a year and the Scottish service £1m.

In the follow-up study the fire section will challenge Euralarm’s technical group to finesse solutions suggested in the initial study and to find further ways to combat the problem.

Euralarm will hope to recreate some real-world successes from the existing study, which was initiated after budget cuts to the fire service. Based on the study’s recommendations fire services in several countries have already changed their practices. For example, in some instances the deployment of firefighters has been made contingent on an additional verification step.

Scale and complexity

It’s a measure of the problem’s scale and complexity that it should require further study, given the original study took three years to complete and the technical group has been considering the problem since 2012.

If progress towards resolving the problem seems frustratingly slow then there is an entirely valid reason: no reduction in false alarms is ever worth a corresponding increase – however small – in the time it takes for alarms, fire safety managers or fire services to respond to genuine fires.

“We have seen that there are positive effects of false alarms and that the number of real identified fires is increasing with the number of installations. However, the proportion between the consequences of real and false alarms is not adequate,” said Sebastian Festag, chairman of the TG False Alarms.

The original study, which took a risk-based approach to studying the problem in Germany, the UK, Switzerland, Sweden and Austria/Vorarlberg, included:

  • Analysis of processes that trigger fire service intervention
  • Formulae to calculate false fire alarm ratios
  • Methodology of overall analysis
  • Recommendations and strategies for reducing false alarms

Recommendations were based on fire statistics, in particular the gap between the number of alarms triggered by actual fires and those caused by other phenomena.

One recommendation was to make false alarms avoidance a priority of site management, with the problem accounted for in fire protection and fire alarm strategies.

The Future of Fire Safety: download the eBook

Is the fire protection industry adapting to the post-Grenfell reality fast enough? At FIREX International 2019, Europe's only dedicated fire safety event, some of the world's leading fire safety experts covered this theme. This eBook covers the key insights from those discussions on the developments shaping the profession, with topics including:

  • Grenfell Inquiry must yield “bedrock change” – and soon
  • After Grenfell: Jonathan O’Neill OBE on how austerity and policy “on the hoof” are hampering progress
  • Hackitt’s Golden Thread: Fire, facilities and building safety
  • Fire safety community has to “get on board” with technological changes

It is not acceptable to have a poor false alarm rate with the excuse real fires might be detected more quickly. This has been an important aspect of managing a fire alarm system since at least 2002. BS 5839-1 clearly sets maximum false alarm rates below which a system is fully compliant. Above that it must be corrected and is not compliant with this section of the BS

Instinctively I feel that using a third party accredited installer for my fire alarm system should give me the confidence of competence but I would also assume that it would minimise the chances of false alarm. If that is so, as we move into the forthcoming building regulations review; I would therefore ask the I would therefore ask of the third party certification bodies, if you possibly can, please provide the evidence that third party certificated systems perform better than the unregulated market.
