Over the last decade, fire protection has been transformed by the rise of addressable, IP-based devices embedded in networked fire alarm system infrastructure. The scalability and modular architecture of digital fire alarm systems has unlocked a new level of fire safety, for instance by pinpointing the exact location of a triggered smoke detector in an alarm, or by interfacing with public address systems for phased building evacuations. For system integrators, installation and maintenance of alarm systems have reached new levels of efficiency – including automated service alerts and far fewer false alarms – with unprecedented cost savings.

Accordingly, the world market for fire alarm systems has seen significant growth, driven by the digitization of existing systems to meet higher safety standards and legislation. Experts at Grand View Research expect the market to increase from $52.2 billion in 2016 to $93.5 billion by 2022. Addressable systems – including IP-networked smoke detectors and fire panels – already account for more than two-thirds of the alarm technologies segment. And, as analog systems are being phased out, their share will soon be 100 percent.

Networked fire alarm systems

With that said, all elements are in place for the second, even more fundamental transformation in fire protection: In the near future, a growing amount of networked fire alarm systems will be connected to the Internet of Things (IoT). In the near future, a growing amount of networked fire alarm systems will be connected to the IoTThis is part of a larger trend across industries, including smart homes and smart buildings automated by a mixture of sensor data and artificial intelligence (AI). The number of IoT-connected devices worldwide is expected to exceed 14 billion by 2022, more than half of the world’s 28.5 billion connected devices.

For technology providers like Bosch, the IoT’s level of networked intelligence calls for a strategic response. “Our strategic target for all of our electronic product categories is to be IoT-enabled by 2020,” said Volkmar Denner, CEO of Bosch. This vision is supported by “3S’s” in Bosch’s connectivity business: sensors, software, and services. In developing and implementing services and solutions for the connected world, Bosch benefits from its expertise in software and sensor technology as well as, in particular, its broad business portfolio.

Remote Services lead the way

When it comes to bringing the IoT into the fire safety segment, Bosch envisions a future in which connected devices – and their data – open up new kinds of services that offer significant benefits to end customers and system integrators. This digital transformation journey is already well underway, as IoT-based applications are already enhancing the fire safety service offering on several levels. As a prerequisite, networked system architecture such as fire panels and sensors need to connect to the internet via nodes, hubs, and gateways in a secure manner. With this connection in place, the system can communicate with a cloud application server via IP protocol to send real-time data such as device health, battery status, and event history.

Networked system architecture such as fire panels and sensors need to connect to the internet via nodes, hubs, and gateways in a secure manner

Because system integrators can access these data points from any location without physically visiting the installation on-site, the impact of the IoT so far has been most pronounced in the Remote Services segment with the following three focus areas:

  1. Remote Connect. Allows for the remote set-up of a system and programming to customer specifications. Offers cost savings, as set-up can be handled practically without leaving the office for each new installation. Requests for changes can also be implemented at faster turnaround.
  2. Remote Alert. In case of fire, the system sends an alert via the remote portal, which can be integrated with messaging systems. Integrators also receive alerts for device outages and malfunctions.
  3. Remote Maintenance. The system performs regular health checks and condition monitoring, sent at user-specified intervals. Smart fire detectors also ping administrators for electromagnetic pollution or contamination with dust.

Major efficiency gains for system integrators

While IoT-based Remote Services already provide major efficiency gains for system integrators, we’re only just scratching the surface of what is possible. At the same time, the foundation for next-generation IoT-connected services is already created today, as the integration between sensors, software, and services increases.It will not only be crucial for devices to work together within the same network

In the process of building end-to-end fire safety systems that are ready to connect with the IoT, seamless interfaces with third-party apps and platforms via APIs (Application Programming Interfaces) will be a competitive advantage for system technology providers. It will not only be crucial for devices to work together within the same network. It will be even more important that systems can communicate with apps or building management software.

On the same note, the ability to provide integrated, IoT-connected services on a secure backbone – safe from hackers and malicious attacks – will be indispensable, because system data is the most valuable resource moving forward. Analyzed correctly, this data holds the key to what comes next.        

Smart data instead of Big Data

Needless to say, the rise of IoT-connected fire alarm systems will create massive amounts of data. This new ‘Big Data’ reality will call for improved data processing capabilities. Not just in terms of quantity: The most relevant services will be derived from smart data provided by IoT solutions in fire safety. The focus lies with data points that matter and making this data actionable by practice-oriented analysis.

For a quick glimpse into the process, our IoT data scientists are currently running comparative analyses of several fire alarm systems to gain visibility on problematic incidents, for instance when devices trigger false alarms. New services will have the potential to transform the way in which fire alarm systems are maintainedIn the next step, categorizing all systems that report such incidents into clusters would allow to give system integrators a big picture overview pinpointing exactly those among their managed systems that are at risk and need inspection, repairs, or upgrades. On the technical level, Bosch is using Mongo DB, a universal, document-based database for apps, to perform these quantitative analyses, always with a focus on new services and benefits for customers.

As our understanding of this data increases, new services will become possible that have the potential to transform the way in which fire alarm systems are maintained and managed. Whereas today, system integrators can view data points such as device status in their Remote Portal and offer basic maintenance support via cloud-connected apps, tomorrow their service approach will be much more proactive, again thanks to smart data.

The next level of IoT-powered services

In the future, data from IoT-connected systems can be leveraged to predict automatically at what exact point in time a system component is going to fail. Instead of replacing said component ahead of time, as is the case in today’s preventive maintenance approach, this new predictive service protocol allows to save cost by making maximum usage of the device’s lifespan.This new predictive service protocol allows to save cost by making maximum usage of the device’s lifespan

In the bigger picture, the data log of a particular fire alarm installation’s data can provide the basis for targeted system optimization efforts. For instance, if long-term data indicates that sensors in a particular area tend to trigger false alarms because of signal interference, the integrators can perform a deep dive into whether nearby high-voltage cabling is the cause and make adjustments to system architecture accordingly. In the same vein, integrators gain transparency on whether detectors in a certain location tend to need replacement due to dust and contamination, or if electromagnetic compatibility (EMC) with other systems like voice broadcast is causing issues – and take preventative measures.

Self-monitoring Fire alarm systems

Overall, these data points, together with constant real-time information on system health, will provide system administrators with the tools for planning and maintaining fire alarm systems in a more efficient manner. They can design and install new systems based on the data-powered learnings from previous installations. And they can provide a more customer-centric response to information requests or inquiries for system updates.

Most of all, the connection to IoT-based services will provide a new peace of mind: These upgraded fire alarm systems will quietly monitor and secure themselves, and only trigger alarms or notifications when service is needed, while system integrators can focus on more important tasks. Right now, we are building the foundation for making these new IoT-driven services a reality. But compared to what the IoT has is store for the future design of fire alarm systems in buildings, we have only seen the beginning. The biggest benefits are still to come.

In A Busy Wildfire Season, Researchers Seek New Approaches
In A Busy Wildfire Season, Researchers Seek New Approaches

It makes perfect sense that a horrific wildfire season would come in the year 2020 on the heels of a pandemic. Dozens of major fires burned across North America in September, including 85 large uncontained fires and six contained fires across 12 states. Active fires have burned more than 3 million acres already, and 41,417 fires have burned almost 5 million acres year-to-date. The severity of the wildfire season is on track to surpass the 10-year average. Better understanding wildfires Global warming is often mentioned as a contributor to the wildfires, but there are other factors, too. Increasingly, researchers are looking to apply new approaches in address the risk of wildfires. They include tools such as deep learning and artificial intelligence (AI) to better understand wildfires and to control their intensity. The model could be used to reveal areas of greatest risk for wildfires A new deep learning model uses remote sensing and satellite data to trace fuel moisture levels across 12 Western states, in effect tracking the amount of easily burnable plant material and how dry it is. After additional testing is complete, the model could be used to reveal areas of greatest risk for wildfires and to plan the best areas for prescribed burns. Led by a Stanford University ecohydrologist, the research was published in the journal Remote Sensing of Environment. Recurrent neural network The model uses data from the U.S. Forest Service’s National Fuel Moisture Database, which amasses plant water content information from thousands of samples. Using a ‘recurrent neural network,’ the system leverages the fuel moisture data to corroborate measurements of visible light and microwave radar signals from spaceborne sensors that are tasked with estimating fuel moisture measurements. Newer satellites with longer wavelengths allow sensitive observations about moisture content deeper into the forest canopy. Estimates from the model are used to generate interactive maps that fire agencies may one day use to identify patterns and prioritize wildfire control estimates. Researchers are also working to analyze the impact of better and more efficient firefighting on the size and frequency of wildfires. The theory goes: When firefighters extinguish smaller vegetation fires, a consequence is the creation of an environment where wildfires are larger and/or more frequent. Natural cycle of regeneration Older woods will naturally catch fire from the sun’s heat to make way for fresh growth The theory is based on the premise that wildfires play an essential role in the periodic regeneration of forests. Older woods will naturally catch fire from the sun’s heat to make way for fresh growth. However, more efficient firefighting can disrupt the natural cycle and, along with global warming, aggravate the broader likelihood of larger and more frequent fires. Researchers at the WiFire Lab in California and the University of Alberta in Canada are using artificial intelligence (AI) to analyze the environment and provide recommendations for prescribed burns that can save some parts of the forest without interfering with the natural cycle of regeneration. Providing early warning of wildfires Equipment operated by Pacific Gas and Electric (PG&E) caused 2018’s Camp Fire, the most destructive wildfire in California history. Because of the threat of sparking a wildfire, PG&E this year shut off power to 172,000 customers in Northern California on Labor Day weekend, for example. A concern is the threat of winds tearing down power line or hurling debris into them. Southern California Edison (SCE), another utility, warned that about 55,000 customer accounts could lose power. California utilities SCE, PG&E and San Diego Gas and Electric are helping to fund a network of ALERTWildfire video cameras in California that will help to provide early warning of wildfires. Video cameras keep watch throughout five Western United States to provide early warning, and the number of cameras is growing fast.

Should Firefighters And First Responders Use Face Masks?
Should Firefighters And First Responders Use Face Masks?

Should firefighters and other first responders be exempt from requirements that they wear face masks to prevent spread of the novel coronavirus (COVID-19)? The City Council of Portsmouth, New Hampshire, seems to think so. They are proposing an amendment to exempt first responders from complying with the city’s face mask ordinance. Amendment to Exempt first responders from face mask rule Specifically, the proposed amendment states, “Exempted from the requirements of the ordinance requiring wearing of face coverings include law enforcement personnel, first responders or other workers, who are actively engaged in their tasks, if wearing a face covering may hinder their performance.” The Centers for Disease Control and Prevention (CDC) recommends that everyone wear masks in public settings The Centers for Disease Control and Prevention (CDC) recommends that everyone wear masks in public settings, especially when social distancing cannot be maintained. The CDC does not specify a need to exempt first responders. However, there is a possibility that a mask could interfere with the work of firefighters or first responders, especially when they are performing tasks that require physical exertion. Face masks can inhibit communication among first responders Face masks, covering the mouth and nose, could also inhibit communication by muffling sound and obstructing facial expressions. Obviously, communication is of paramount importance for firemen working as a team in an emergency, or when a first responder is seeking to give clear directions to the public. The issue of face masks has been inexorably entwined with the well-being of first responders, since the beginning of the COVID-19 pandemic. Early on during the infection spread, health officials dismissed face masks as a tool to avoid spread of the disease. They said that the masks were ineffective at preventing community spread and that, supplies of personal protective equipment (PPE) needed to be conserved for health professionals and first responders. Importance of face masks in controlling spread of COVID-19 However, the early advice was completely reversed in late March 2020 and masks have been advocated ever since. A mask, worn by an infected individual, reduces the dispersion of virus-laden droplets that spread the disease. Now, experts contend that any type of mask, including cloth or paper, can help to reduce spread of the COVID-19 virus. Expanding the use of masks to include those that are not conformant with the N-95 classification effectively eliminated any concerns about supply and helped to make the widespread use of masks the norm. To some extent, however, mask usage in the United States has been politicized and some see the requirements as an affront to liberty. Need for wearing face masks in public Masks are a useful preventative measure for firefighters working together in a communal area Fire and emergency departments face the same challenges as other businesses and institutions, as they seek to remain safe in a communal workspace. Masks are a useful preventative measure for firefighters working together in a communal area or when training or resting. Wearing masks in public also allows departments to model best practices and promote a positive perception of the department to the public. Disciplined use of face masks demonstrates unselfishness and respect for others. It communicates professionalism and concern for the greater good. Masks go a long way in saving lives of first responders Perception may also be an issue when it comes to the choice of masks, which become a de facto part of a uniform. Masks with political statements should be avoided, for example. Considering that dozens of American fire and EMS members have died of COVID-19 infection, since March 2020, the use of masks is another way that firefighters can work to save lives. However, sufficient flexibility is needed so that the use of masks does not interfere with other lifesaving duties.
