You will be aware of the frustration and rolling impacts false alarms in fire detection systems have on a business. It may even be why you clicked on this blog! False alarms can lead to business disruption, financial loss and the wasted precious time of the emergency services. If your business is experiencing an increased amount of false alarms, keep reading, as we dive into effective strategies to reduce false alarms in fire detection systems.
A false alarm for fire detection systems is the triggering of a fire alarm signal from the system that is not caused by a fire. The system therefore falsely detects what it thinks is a fire and alerts the site via an alarm bell or siren. While these events are often viewed as a mere nuisance, they represent a significant drain on national resources. In fact, the latest data from the Home Office reveals that false alarms continue to be the largest incident type attended by Fire and Rescue Services, accounting for 38% of all incidents in the most recent reporting year.
There are several potential causes of false fire alarms, some of which may be more prone within specific industries or natures of a business. Some of the potential causes of false alarms in fire detection systems include:
When a false alarm is activated, a site will likely respond as per its protocol and fire safety plan. Many sites will not be able to immediately identify if an alarm is false and therefore will undertake their evacuation process. However, responding to false alarms can lead to unnecessary disruptions, panic and a waste of critical resources. Recent research indicates that the financial burden of these disruptions across the UK economy remains in the hundreds of millions annually due to lost productivity.
If repeated false alarms occur on a site, it may also lead to complacency among employees if they start to perceive their building’s fire alarm as a false positive or think ‘it’s properly a false alarm’. This thinking puts a business’s workforce and their safety in jeopardy, which is why understanding legal responsibility in fire incidents is vital for every business owner. Addressing the issue of false alarms as soon as possible ensures you remain compliant with the Fire Safety Order and keep your staff protected.
To reduce false alarms, effective strategies need to be put in place to ensure an accurate and reliable fire detection system. Reducing false alarms ensures that emergency response resources, such as the fire brigade, are utilised effectively only responding to events that actually need their attention. These strategies also ensure the system maintains credibility and trust among a business and its employees. Here are our top strategies for reducing false fire alarms.
Proper and professional installation of a fire detection system by a qualified engineer specialising in fire safety systems is key to ensuring a safe and reliable system that will have limited false alarms.
Having an effective maintenance contract in place is also key to ensuring your fire alarm system is kept in good condition and there are no faults or issues that could be causing false fire alarms. A yearly maintenance visit is always advised but regular inspection of the system is also an effective strategy to make sure any issues are solved promptly. Ensuring you have industry-recognised accreditations for your service provider guarantees that your maintenance meets the highest safety standards.
Every site is different and will have different fire safety risks and needs. Installing the right fire safety technology for the site is therefore key to ensuring there is appropriate fire detection technology in place for the environment. For example, a professional kitchen with lots of steam and heat will need a different type of fire detection than a high-rise office building.
Some business sites may also choose to install certain technology that can help improve the accuracy of fire detection and reduce false alarms such as multi-sensor detectors that combine different technologies, instead of relying on just one. This is particularly important when choosing the right fire detection system for complex layouts where standard optical sensors might fail.
As touched on earlier, installing the right detection system for the site is key to reducing false alarms, which includes considering the environment it will be installed. Fire detectors should not be placed in areas prone to steam, high humidity or dust as these can all trigger a false alarm. For industrial settings, factory environments require specialised hardware that can distinguish between manufacturing byproducts and actual smoke. A professional fire safety installer will be able to advise on the very best fire detectors to install for your specific environment.
Another effective strategy for reducing false alarms is to ensure your fire wardens carry out regular testing of the fire detection system to ensure it is functioning properly. The Regulatory Reform (Fire Safety) Order 2005 (RRO) states fire alarms must legally be carried out weekly, with inspections carried out every six months as a minimum.
You can also use a professional fire safety provider to carry out your system testing. They may use smoke and heat sources to stimulate real fire conditions to test the system’s responsiveness without causing false alarms. This proactive approach is part of predictive maintenance in fire safety, which helps identify failing components before they trigger a false event.
To effectively reduce false alarms it’s important to identify and replace ageing systems and components. New technologies are constantly being developed and with this comes better accuracy in fire detection and reduced false alarms. If your fire safety system is over 15 years old, it could be a good idea to bring in a specialist to see how they can improve or update your updated fire detection system. Modern systems often utilise advanced sensors and real-time analytics to filter out non-fire phenomena more effectively than older hardware.
A reason for false alarms could be interference from other sources such as dust, insects or other electricals. Addressing these interferences and eliminating them will be an effective strategy for reducing false alarms within your fire detection system. Putting in measures to protect your detectors, such as installing barriers or shields is likely to reduce false alarms. In sectors like logistics and warehousing, where high ceilings and dust are common, the right shielding is essential for system stability.
Educating staff can be a key part of reducing false alarms, especially in terms of the consequences involved and the importance of not tampering with or obstructing the fire detection system and its varying components. Creating fire safety champions within your team is an effective way to maintain high standards of awareness. Preparing guidelines for staff on what can potentially trigger a false alarm, such as improper use of toasters or aerosol sprays, is essential in reducing them.
Dividing a site into zones and compartments, each with its own fire detention system in place can help localise alarms and reduce the impacts of false alarms on the entire site. This can also help identify false alarms more quickly which will lead to reduced business disruption. For those in property management, clear zoning is not just a safety benefit but a legal requirement to ensure rapid identification of fire sources in multi-tenanted buildings.
Working with a remote monitoring provider to carry out 24/7 monitoring of your site’s fire detection system is arguably one of the most effective means to reducing fire alarms as well as their impact on a site and the overall business. Every alarm that is triggered will be instantly picked up by an in-person monitoring operative who will confirm whether the alarm is false or a true trigger.
If it is false, they can quickly turn off the alarm and notify the site keyholder. If it is due to a real fire being detected, then they can escalate the issue and contact the emergency services on behalf of the site. Remote monitoring for fire systems helps sites to focus their efforts on what matters and leave the responsibility of fire alarms and determining their validity to the professionals.
