London Fire Brigade to change response to automatic fire alarms in non-residential buildings during daytime

Policy change to reduce false fire alarm responses

As reported by the London Fire Brigade, the Brigade will implement a new policy starting in October 2024.

The Brigade will cease attending automatic fire alarms in most non-residential buildings, such as office blocks and industrial estates, during daytime hours unless a call is also received from a person reporting a fire.

Between April 2023 and March 2024, the Brigade responded to approximately 52,000 false alarms generated by automatic fire alarms.

The policy aligns with practices of almost all other UK fire and rescue services, aiming to utilise firefighters’ time more effectively to enhance community safety.

The Brigade will continue to respond to all automatic fire alarms in residential buildings, schools, nurseries, hospitals, care homes, heritage sites, and other exempt premises.

Additionally, the policy will apply only between 7am and 8.30pm, with responses to all alarms resuming outside these hours.

Consultation and stakeholder engagement

The changes follow a comprehensive consultation last year involving the public, businesses, partners, firefighters, and other Brigade staff.

The consultation’s feedback led to adjustments, including an expanded list of exempt premises.

Deputy Commissioner Charlie Pugsley stated: “Following a consultation with key stakeholders, it is clear that support for the new policy recognises the benefits these changes will have on our service for Londoners.”

Ahead of the policy rollout, the Brigade will work closely with stakeholders, businesses, community groups, and Londoners to ensure they understand the changes, prepare accordingly, and maintain the safety of their buildings and occupants.

Pugsley added: “We are here to keep London’s communities safe, and we want to do this as effectively as possible.”

Impact on firefighter training and community safety

Less than 1% of automatic fire alarms signal genuine fires, with the remaining 99% being false alarms, which burden the Brigade’s resources.

The time spent attending these false alarms will instead be used to improve operational training for firefighters and enhance fire prevention and safety in local communities.

The National Fire Chiefs Council and His Majesty’s Inspectorate of Constabulary and Fire & Rescue Services support efforts to reduce false alarm attendances.

The Brigade emphasises the importance of managing and maintaining automatic alarm systems to minimise false alarms.

Common causes include poor alarm design or maintenance, dust inside detectors, or steam.

Businesses experiencing recurring false alarms are urged to investigate each occurrence and contact their alarm system company to resolve issues.

Reasons for false alarms

False alarms occur due to various reasons such as poor alarm design or maintenance, dust in detectors, or steam.

Ensuring automatic alarm systems are correctly managed and maintained is crucial to minimise false alarms.

Additionally, staff in businesses should be suitably trained to understand their responsibilities under fire safety law.

Recurring false alarms can often be resolved quickly and easily.

Deputy Commissioner Charlie Pugsley explained: “As outlined in our Community Risk Management Plan, reducing our attendance at false alarms will give firefighters more time to focus on preventative activity, such as visiting our most vulnerable residents and communities, fire safety checks, as well as operational training.”

What is an Ionization Fire Detector?

In fire safety, fire detection plays a crucial role in early warning systems. 

Among these detectors, ionization fire detectors are one of the most common. 

But what exactly are ionization fire detectors, and how do they work? 

This article should give you the information on everything about ionization fire detectors, including their advantages and disadvantages, and how they stack up against other types of fire detectors.

What is an Ionization Fire Detector?

ionization fire detector image

An ionization fire detector is a type of fire alarm device designed to detect the presence of smoke particles in the air. 

It operates on the principle of ionization, utilising a small amount of radioactive material to ionize the air within the detector. 

When smoke enters the detector, it disrupts the ionization process, triggering the alarm.

Walter Jaeger, a Swiss physicist, is frequently attributed with the creation of the inaugural functional ionization smoke detector in 1943.

How Does an Ionization Fire Detector Work?

how ionization fire detector works

An ionization fire detector operates on a simple yet effective principle to detect the presence of smoke particles in the air. 

It utilises the process of ionization, facilitated by a small amount of radioactive material, typically Americium-241

The detector consists of an ionization chamber, a hollow enclosure containing two electrodes and a small radioactive source. 

The radioactive material emits alpha particles, which ionize the air within the chamber.

When alpha particles emitted by the radioactive source collide with air molecules in the chamber, they ionize them, creating positively and negatively charged ions. 

This process generates a small electric current between the electrodes.

Under normal conditions, the ionization process maintains a stable electric current between the electrodes. 

This current serves as a baseline for the detector’s operation.

When smoke enters the ionization chamber, it disrupts the ionization process. 

Smoke particles interfere with the movement of ions, causing a decrease in the electric current between the electrodes.

The drop in electric current triggers the alarm mechanism of the detector. 

The alarm may emit a loud sound, flash lights, or activate a connected fire alarm system, alerting occupants to the presence of smoke and potential fire.

What are the Benefits to an Ionization Fire Detector?

ionization fire detector benefits

Ionization fire detectors offer several benefits that make them valuable components of fire detection systems:

Fast-Flaming Fires 

Ionization detectors are highly sensitive to small smoke particles produced by fast-flaming fires, such as those caused by burning paper or flammable liquids. 

This sensitivity allows them to provide early warning in the critical early stages of a fire, giving occupants more time to evacuate safely and firefighters a better chance to contain the blaze.

Quick Response Time

Ionization detectors have a rapid response time, triggering the alarm promptly when smoke particles enter the ionization chamber and disrupt the electric current. 

This quick response is essential in emergency situations, helping to minimize the spread of fire and reduce property damage.

Availability and Affordability 

Ionization fire detectors are widely available and relatively affordable, making them accessible to homeowners, businesses, and organizations of all sizes. 

Their affordability allows for widespread deployment in residential and commercial buildings, enhancing overall fire safety.

Compatibility

Ionization detectors are compatible with standard fire alarm systems, allowing them to integrate seamlessly into existing fire protection infrastructure. 

They can be interconnected with other detectors, sirens, and monitoring systems to provide comprehensive coverage and centralized control.

Simple Installation and Maintenance

Ionization detectors are easy to install and require minimal maintenance. 

They can be mounted on walls or ceilings using simple hardware and do not require complex wiring or configuration. 

Routine maintenance typically involves periodic testing and battery replacement to ensure proper operation.

Effectiveness in Various Environments

Ionization detectors are effective in a wide range of environments, including residential homes, commercial buildings, and industrial facilities. 

They can detect smoke particles in open spaces, hallways, and enclosed rooms, making them versatile solutions for diverse fire detection needs.

What are the Downsides to an Ionization Fire Detector?

ionization fire detector downsides

While ionization fire detectors offer several advantages, they also have some downsides that should be considered:

Slow-Smouldering Fires

Ionization detectors are less sensitive to larger smoke particles produced by slow-smouldering fires, such as those caused by overheated electrical wiring or smouldering upholstery. 

These types of fires may produce less visible smoke and take longer to generate enough smoke to trigger an ionization detector, potentially delaying the alarm and increasing the risk of injury or property damage.

False Alarms

Ionization detectors are prone to false alarms, particularly in environments with high levels of dust, steam, or cooking fumes. 

These environmental factors can disrupt the ionization process and trigger false alarms, leading to nuisance alarms and potential complacency among occupants.

Radioactive Material

Ionization detectors contain a small amount of radioactive material, which is used to facilitate the ionization process. 

While the amount of radioactive material is minimal and considered safe for use in consumer products, some individuals may have concerns about the presence of radioactive material in their homes or workplaces.

Environmental Impact

The manufacturing and disposal of ionization detectors may have environmental implications due to the radioactive material they contain. 

Proper disposal of ionization detectors is necessary to prevent environmental contamination and ensure compliance with regulations governing the disposal of radioactive waste.

Limited Coverage Area

Ionization detectors are most effective at detecting smoke particles in open spaces and may have limited coverage in enclosed areas or rooms with obstructions. 

Supplementing ionization detectors with other types of detectors, such as photoelectric or heat detectors, can help overcome this limitation and provide more comprehensive fire detection coverage.

Incompatibility with Certain Environments 

Ionization detectors may not be suitable for certain environments with high levels of airborne contaminants or extreme temperatures, as these conditions can affect their performance and reliability.

What Other Types of Fire Detectors are Available?

fire detector types

In addition to ionization fire detectors, several other types of fire or smokes detectors are available, each offering unique advantages and capabilities:

Photoelectric Fire Detectors

Photoelectric fire detectors operate on the principle of light scattering. 

They contain a light source and a photosensitive receiver. 

When smoke enters the detector chamber, it scatters the light, triggering the alarm. 

Photoelectric detectors are highly sensitive to slow-smouldering fires and are less prone to false alarms from steam or cooking fumes.

Heat Detectors

Heat detectors are designed to detect changes in temperature rather than smoke particles. 

They are ideal for environments where smoke detection may be less effective, such as kitchens or garages. 

Heat detectors are available in fixed temperature and rate-of-rise models, which activate when the temperature exceeds a predetermined threshold or rises rapidly.

Dual Sensor Detectors

Dual sensor detectors combine the capabilities of ionization and photoelectric detectors into a single device. 

By integrating both sensing technologies, dual sensor detectors can provide comprehensive fire detection coverage, detecting both fast-flaming and slow-smouldering fires while minimising false alarms.

Air Aspiration Systems

Air aspiration systems use a network of pipes and sampling points to continuously draw air samples from the protected area. 

These samples are analyzed for the presence of smoke particles using sophisticated detection algorithms. 

Air aspiration systems offer highly sensitive and early detection of fires, making them suitable for high-value assets and critical infrastructure.

Flame Detectors

Flame detectors are designed to detect the presence of flames or combustion sources, such as those produced by gas or oil fires. 

They use optical sensors to detect the characteristic flicker of flames and can provide rapid detection in environments where smoke detection may be ineffective or impractical.

Ionization vs Photoelectric Fire Detectors

ionization vs photoelectric fire detector

Ionization and photoelectric fire detectors are two distinct types of smoke detectors, each offering unique advantages and capabilities. 

Ionization detectors excel at detecting fast-flaming fires, thanks to their high sensitivity to small smoke particles. 

They operate based on ionization, using a radioactive material to ionize the air within the detector chamber. 

However, ionization detectors may be less effective at detecting slow-smouldering fires, as they are less sensitive to larger smoke particles.

In contrast, photoelectric detectors are highly sensitive to larger smoke particles and are particularly effective at detecting smouldering fires. 

They work based on light scattering, utilising a light source and photosensitive receiver to detect changes in light patterns caused by smoke particles. 

While photoelectric detectors may have a slower response time to fast-flaming fires compared to ionization detectors, they are less prone to false alarms from environmental factors such as dust or cooking fumes.

Ultimately, the choice between ionization and photoelectric detectors depends on the specific fire detection needs and environment. 

Combining both types of detectors can provide comprehensive fire detection coverage, ensuring effective early warning in a variety of fire scenarios.

Ionization vs Heat Fire Detectors

ionization vs heat fire detector

Ionization, photoelectric, and heat fire detectors are three primary types of fire detection devices, each offering unique strengths and capabilities.

Ionization detectors are highly sensitive to small smoke particles produced by fast-flaming fires, making them effective at providing early warning in such situations. 

They operate based on ionization, using a small amount of radioactive material to ionize the air within the detector chamber. 

However, they may be less effective at detecting smouldering fires, as they are less sensitive to larger smoke particles.

Heat detectors are designed to detect changes in temperature rather than smoke particles. 

They are ideal for environments where smoke detection may be less effective, such as kitchens or garages. 

Heat detectors are available in fixed temperature and rate-of-rise models, which activate when the temperature exceeds a predetermined threshold or rises rapidly.

Conclusion

Ionization fire detectors serve as vital components of fire detection systems, offering early warning capabilities in the event of a fire. 

While they excel at detecting fast-flaming fires, they may have limitations in detecting slow-smouldering fires. 

By understanding their strengths and weaknesses, users can make informed decisions about incorporating ionization detectors into their fire safety plans, ensuring comprehensive protection against the threat of fire.

Exploring Dryad Networks’ digital forest that is changing the face of early wildfire detection

Dryad Networks, led by CEO and co-founder Carsten Brinkschulte, is using advanced sensor technology and IoT to pioneer early wildfire detection

The inspiration for Dryad Networks came to Carsten Brinkschulte CEO and co-founder in 2019 during a particularly intense period of wildfires which received widespread coverage in the news.

After selling a previous company, he found himself at a crossroads, and so decided to utilise his background in telecommunications and technology to address this global issue

Wildfires contribute to up to 20% of global CO2 emissions, equal to the emissions from all vehicular traffic annually.

By mitigating wildfires, Brinkschulte says Dryad’s aim is to substantially reduce carbon emissions, but we can also safeguard biodiversity and minimise financial losses, which range from £180 billion to £900 billion annually.

Silvanet

Silvanet is Dryad’s complete solution for early wildfire detection, along with forest management, growth and health and monitoring.

Derived from the Latin word for ‘forest network,’ it represents Dryad’s foundational technology.

“We are essentially constructing a network within forests to host various applications, the primary one being wildfire detection,” Brinkschulte explains.

“This network utilises sensors capable of detecting the earliest stages of a fire and then communicates the exact location of the fire via geo-coordinates to firefighters.”

The backbone of this system is a large-scale low power, wide area network, which operates similarly to Wi-Fi but is designed for expansive outdoor environments.

It has the enhanced capability to establish a mesh network using robotics, allowing for the creation of extensive IoT networks within forested areas.

These devices are solar-powered and mounted on trees, creating a communications bubble approximately one to two kilometres in radius around each gateway.

“Within this network, we deploy sensors that are specifically designed to detect the presence of a fire by sensing the gases emitted,” he elaborates.

“This integration of advanced sensor technology with IoT infrastructure significantly enhances our ability to detect forest fires swiftly and accurately.”

IoT

Traditional forest fire detection methods predominantly rely on human observation, either by individuals spotting fires from nearby locations and alerting emergency services, or by personnel using binoculars in lookout towers to watch for smoke.

There are also technical methods such as cameras that replicate this visual scanning for smoke plumes above the tree canopy, and satellites that can detect fires from space.

Silvanet represents a new approach by employing gas sensors embedded directly in the forest.

“The sensors detect the specific gases produced by organic combustion, offering an advantage in early fire detection,” says Brinkschulte.

“Traditional satellite technology, while providing an excellent overview for tracking and predicting fire paths, is less effective for detecting small fires due to its high altitude or infrequent passes.

“Cameras, although useful over large areas, cannot detect fires that are concealed under the tree canopy and are less effective at night.”

Dryad’s gas sensors, on the other hand, are positioned close to potential ignition points on the forest floor—such as near paths, campsites, and along power lines—where human activity might spark fires.

“This proximity allows them to detect nascent fires long before they grow large enough to be visible to cameras or satellites,” he explains.

“This early detection capability is crucial for enabling quick response, which is vital for controlling fires while they are still manageable.”

Reliable data

Ensuring the accuracy and reliability of fire detection via IoT sensors, particularly when using gas sensors, presents challenges, primarily due to the complexity of distinguishing genuine fire signatures from other similar signals.

To tackle this issue, Dryad has employed machine learning technology directly within the sensors: “The AI is designed to determine whether the detected gases are indeed indicative of a fire or merely other common but unrelated elements, such as exhaust from a passing diesel truck,” says Brinkschulte.

This use of AI at the sensor level, also known as edge computing, is crucial for Dryad’s system.

“Since our network operates on a narrowband technology, it cannot support the transmission of large volumes of data,” he clarifies.

“By processing data locally within the sensors, we can maintain high accuracy and significantly reduce the likelihood of false positives.

“This method ensures that our fire detection system is both reliable and effective in real-world conditions.”

Proximity

The effective range of one of Dryad’s sensors for detecting a fire is approximately 100 metres in radius, roughly the size of a football field.

This range, says Brinkschulte, allows for early detection, which is crucial in preventing the escalation of fires.

The ability of a sensor to detect a fire within this range depends on several environmental factors such as the volume of combustible material, wind speed and direction, and temperature.

“While our sensors can detect fires beyond this range, the fire would need to grow larger and emit more gases to be detectable at greater distances,” says Brinkschulte.

“That is why our focus is primarily on early detection within high-risk and high-value areas, particularly in the wildland-urban interface, where accurate and early detection is most critical.”

This is achieved this with low-cost, easy-to-install sensors that are designed for longevity and do not require batteries, reducing the risk of introducing potential ignition sources into the forest.

The sensors are compact, about the size of the palm of a hand.

The installation process involves simply drilling a small hole into a tree trunk and securing the sensor with a wooden nail – a method designed to minimise impact on the tree and allow the sensor to remain securely in place for up to ten years.

“We use solar power and supercapacitors for energy,” he tells, explaining that the design philosophy ensures that even though each sensor covers a limited area, they are deployed strategically to maximise coverage and resolution.

Environmental focus

Brinkschulte takes the environmental impact of deploying IoT devices in natural habitats very seriously.

“Our sensors and gateways are designed to be as non-invasive as possible, crucially excluding batteries to eliminate the risk of fire hazards,” he stresses.

“Instead, we utilise supercapacitors and solar panels to power these devices, which negates the introduction of potentially hazardous materials into the forest.”

The primary goal of the detection devices is to mitigate wildfires, particularly those that are human-induced and occur at the wildland-urban interface where property and infrastructure are most at risk.

“By focusing on early detection and prevention, we aim to reduce both the environmental and economic impacts of wildfires,” says Brinkschulte.

Looking ahead

Dryad’s vision is to expand the capabilities of IoT in environmental monitoring well beyond the focus on fire detection.

Future applications include the development of fuel moisture sensors, which will help us assess and manage fire risks by measuring ground moisture.

Additionally, the company has plans to monitor other crucial ecological metrics, such as tree growth, soil moisture levels, and even the water flow within tree stems.

These advancements will utilise the existing Silvanet network infrastructure, essentially turning it into a ‘nervous system’ for the forest, broadening its impact on global sustainability.

Brinkschulte shares Dryad’s most ambitious goal, what has calls their ‘moonshot: To develop an autonomous system for extinguishing fires.

“This project hinges on securing the necessary funding, but if successful, we plan to spend the next three years creating an autonomous drone that can actively extinguish fires detected by our network,” he reveals.

“This innovation could significantly enhance our ability to respond to and manage forest fires, marking a significant milestone in the integration of IoT technology with environmental preservation and sustainability efforts.”
