BBC Fire & Security, a company that designs, installs, inspects and services fire systems highlights information from the Fire Industry Association that estimates that false fire alarms cost the UK more than £1bn per year. It adds: “Much of this cost is from lost production and interruptions to business, but there’s also a dangerous effect on peoples’ behaviour if they inhabit or use buildings that experience a lot of false alarms. Frequent false alarms in a building can cause people to become complacent and less willing to react when a fire alarm actuates which could be fatal.

“Over the past 10 years, the Emergency Services in England have responded to an average of 237,418 false alarms each year. 67% of these False Alarms were due to ‘apparatus’.*

The latest figures published by the Government estimate that the cost of false alarms in the UK is around £1 billion a year.* Much of this cost is borne by commerce from lost production and interruptions to business.”


The impact of false alarms and unwanted fire signals

• Major disruption to business effectiveness, efficiency, profitability & services

• Erode user’s confidence in the value and reliability of their fire detection system – frequent false alarms in a building can cause staff to become complacent and less willing to react when a fire alarm actuates

• Diverting essential services from true emergencies

• Unnecessary risk to fire crew and public whilst responding (accidents)

Disruption to arson reduction, community safety and fire safety activities

• Drain on public finances


Reducing false alarms

Thankfully, there is a lot you can do to reduce false alarms. Much of it is simple common sense – and part of your legal responsibilities already. 

The company recommends:

1.Make sure the fire alarm design suits the premises design and use

Make sure your alarm is fit for purpose. If your business activity has changed or the building itself has changed you may need to review the types of detectors you have and where they are positioned, you should review the Fire Risk Assessment.

2.Make sure the alarm system is properly and regularly maintained

Regular servicing and maintenance will ensure your fire alarm system is compliant and working as it should be. Ensure you have your system maintained by a third party certified maintenance company to reduce false activations.

3.Replace ageing systems and components

Manufacturers generally recommend the replacement of detectors between 10 and 15 years, the recommended age varies across the wide range of manufacturers. Ageing equipment can be a cause of false alarms as the components start to fail. As equipment becomes obsolete some service providers may try to keep the system going, but this is a false economy as call out charges and the disruption caused soon adds up.

4.Investigate false alarms and work to build in measures that prevent unnecessary recurrence

Review procedures – does your alarm need to be on auto dial during occupied hours? Are all staff aware when the alarm is being tested and can you isolate areas whilst testing? Train staff to safely investigate the causes of any alarm so you can confirm any incident.

Working in partnership with Siemen’s, BBC Fire & Security install the world’s only neural fire detector – the Siemens ASA neural fire detector.

Specifically designed to eliminate false fire alarms in environments with highly deceptive phenomena, such as CO2, steam, aerosols, or dust, the ASA neural fire detector utilises a unique sensor system which distinguishes genuine smoke from these other phenomena. For more information visit here
