Heat Detectors

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: 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. 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. 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.

Those responsible for the specification of products which go into new modern buildings have been asking for safe, approved cabling, which play a critical part in electrical supply systems. The number of fires in high-rise buildings in Europe and the Middle East have brought the issue of quality of products for fire performance circuits into sharp focus, not least the Grenfell disaster. Meanwhile, new buildings become increasingly complex, with the use of new materials and the designs of many requiring complex electrical systems to support security and fire safety. New and refurbished buildings such as hospitals, schools, shopping malls or airports, may have complex addressable loop fire alarm systems which provide information on individual detectors. Conventional systems only provide information about specific circuits or zones. Indicating exact location of fire, fault For critical alarm circuits in buildings where large numbers of people move about there can be no greater priority than safetyThe addressable systems feature a fire control panel which receives information and status reports from each device, indicating its exact location and if there may be a fire, a fault, heat or contamination. For critical alarm circuits in buildings where large numbers of people move about – many of whom can be vulnerable – there can be no greater priority than safety. The cabling chosen for these systems is therefore critical. If the power to these alarm systems fails because the cabling does not meet the required performance, then the information available for fire and rescue services is directly affected and with it, the chance of finding people who may be in the building. To meet these design challenges, and with the inquiry into the Grenfell disaster still ongoing, it is the use of the very latest technology and science that is taking enhanced fire performance cabling onto a new level. Safe and compliant cable products Decision-makers in the supply chain want reassurance that the products they are specifying are safe and compliant, meeting all recognized specifications. Calls have been made by the Approved Cables Initiative (ACI) for all cable being used in the UK to conform to relevant British, European or international standards amid increasing concerns about the volume of non-approved cables coming onto the market. Installers have welcomed the development of a new generation of fire performance cabling Installers have welcomed the development of a new generation of fire performance cabling which ensures critical fire-safety circuits can continue to operate in the event of a fire from 30 minutes up to 120 minutes. The standard and enhanced cables in the Total Fire Solutions range are tubed, making them a welcome product for contractors with ease of installation. They are all UV stable and they all come with a hard insulant to resist any fault generation over time. These cables meet all relevant industry standards including ISO 9001 and is approved by the leading industry organizations nationally and worldwide including BASEC and LPCB. Carrying out fire risk assessment For the fire and rescue services, the continuity of power means they can continue to read fire alarm system information which can direct them to the seat of the fire and help to locate people who may be in the building. Responsibility for choosing the right system lies with the ‘responsible person’ under the Regulatory Reform (Fire Safety) Order 2005 in business or any other non-domestic premises. This will be the owner, employer, landlord, or may be the facilities manager or building manager. As the responsible person, he or she must carry out a fire risk assessment of the premises and review it regularly and put in place and maintain appropriate fire safety measures. Ultimately, the responsible person faces a fines or jail if they fail to follow these measures and there is a fire. For some buildings, it is crucial to select the highest quality products to meet the most rigorous third-party tests and real-life fire scenarios Any items or products which go into these fire safety systems must be covered by standards set by national, European and international bodies such as British Standards. These will certify that when needed these products will perform their function and operate as expected in real life fire conditions. Ensuring cables meet fire safety standards In support of these standards, cable industry bodies provide testing regimes to ensure that different types of cable are fit for purpose and meet these standards when tested in fire conditions. For installers, or those procuring cables, there is a need to check the cable when it arrives to make sure it is exactly what was specified. Instances of unsafe non-approved cable continue to come to lightFor some buildings, it is crucial to select the highest quality products to meet the most rigorous third-party tests and real-life fire scenarios. These include environments such as hospitals, schools and care homes where older people and children move about. Specifiers looking at new large public sector projects such as hospitals should refer to BS 8519 for the electrical supply, and the most relevant cabling system. Counterfeit Flexible Cords campaign Instances of unsafe non-approved cable continue to come to light. Unsafe flexible cord, intended for use in domestic and industrial applications, has been found on sale in the UK recently, prompting the ACI to issue a fresh alert to the electrical supply chain. The latest find of sub-standard flexible cords is marked ‘Made in Turkey’ and ‘Ermaks’. Samples came to light following the initiative’s recent ‘Counterfeit Flexible Cords’ campaign which alerted the electrical supply chain to dangerous industrial flexible cords. We in the supply chain should all be vigilant to watch out and report these instances of non-compliant cabling wherever we see or suspect they have been installed, while developing only the safest products and systems of our own. We shouldn’t forget that we all have a duty and a responsibility where lives and property are at stake. Importance of MV cables to infrastructure Medium Voltage (MV) cables coming onto the market should be independently approved and certified as compliantThe demand for power has never been greater, with the explosion of development in towns and cities across the UK and the growth of industrial development and technology reliant on consistent supplies. Medium Voltage (MV) cables coming onto the market should be independently approved and certified as compliant as the pressure mounts on the installation of quality products in modern building developments. MV cables are crucial to our infrastructure. Electricity leaves the generating site and is routed via a step-up transformer to take it up to the National Grid distribution voltages of 400Kv, 275Kv and 132Kv. Once in the local area, the supply goes through step-down transformers that reduce the voltage to 415V with domestic supplies tapped off at 230V. To provide power to the sub-stations – very often located on the premises of the establishment that they supply – Medium Voltage (MV) cables are used. MV cables were only developed as the level of voltages increased and the need arose for a greater classification range. design and specification of the cables The technical design and specification of the cables is of paramount importance within the power distribution networkThe size of the market has developed to the point where the global MV cables market was valued at 39.31billion US dollars in 2016 and projected to grow at a rate of more than six percent until 2022. The technical design and specification of the cables themselves is of paramount importance within the power distribution network. There are a number of technical considerations to be taken into account including the size of the installation, the position of the installation in relation to the network and the presence of primary and secondary sub-stations. Prior to installation, a detailed route survey should also be carried out to plan where cables will be jointed and to identify any possible obstructions which may require special civil engineering works such as directional drilling. Underlying the critical nature of supplies to these types of services, the incidence of non-approved cables for these applications also plagues the industry.

The continuity of power in the event of a real fire has never been more important as modern buildings become more complex and the need for the highest quality of products comes under the spotlight. With power for lighting and fire alarms, the fire and rescue services can use the intelligence gathered to evacuate people quickly, confident that they have found all the people in the building. Without power, they are literally scrambling in the dark without good information upon which to make their rescue. The continuity of power will also ensure that sprinkler or water mist systems can continue to operate where they exist. In commercial buildings, there may also be smoke evacuation fans which help to enable safe evacuation. Fire alarms may be digital, with loop systems which will provide information for fire and rescue services  Appropriate Cabling  At the start of a project, the most appropriate cabling should be specified as part of the electrical system rather than at the end of a project. Fire alarms may be digital, with loop systems which will provide information for fire and rescue services across individual areas and floors. At the same time, there are new designs, materials and products continually coming on to the market for major projects, and with it an increasing need for the various parties involved to work closely together to make sure they get it right. There has been an increasing incidence of non-approved cables on the market and unfortunately it is not until cables have been installed, tested or used that issues become clear. For installers, or those procuring cables, there is a need to check the cable when it arrives to make sure it is exactly what was specified. Should there be a problem, have it checked and seek good advice. Keep records of purchase, including reel flanges with batch markings and a sample of the cable markings. Send lengths for testing and then decide on the most appropriate course of action. Choice of cabling is crucial at the start of major projects as issues may occur later  Meeting Rigorous Third-Party Tests  For some buildings, it is crucial to select the highest quality products to meet the most rigorous third-party tests and real-life fire scenarios. These include environments such as hospitals, schools and care homes where older people and children move about. Specifiers looking at new large public sector projects such as hospitals should refer to BS 8519 for the electrical supply, and the most relevant cabling system. It is crucial to select the highest quality products to meet the most rigorous third-party tests This Code of Practice specifies that the type of system selected during the design phase ‘should be derived from a detailed process of consultation with the relevant authorities’ and that ‘the design should be agreed at an early stage.’ The decision-making process for cable selection relevant for life safety and firefighting systems is clearly defined here. This covers three categories ranging from 30 minutes to 120 minutes fire survival time.  Categories 1 and 2 cover means of escape for 30 minutes and then 60 minutes respectively, and these cables are tested in accordance with the relevant codes. Category 3 for firefighting to 120 minutes refers to power and control cables meeting the 120-minute test according to the relevant standards. It should be emphasised that only Mineral Insulated Cable (MIC) or a cable meeting the requirements of BS7846 F120 will meet this criteria. For clarity, BS 8519 does not take precedence over BS 5839 for alarm systems and BS 5266 for emergency lighting. In essence, choosing the most relevant cabling and electrical accessories which will continue to operate under fire conditions has become critical. Application Of Medium Voltage Cables  As the incidence of non-approved cables continues then so the application of Medium Voltage (MV) cables into high-risk environments including hospitals, schools, care homes, industrial sites and sub-stations serving infrastructure sites also becomes critical. In the context off fire engineering, it is important to select the relevant MV Cables in these areas. Adhering to the latest regulations is no longer enough - there needs to be a risk assessment. In order to do this effectively, it is important to ask – are the fire safety procedures up to date? All AEI MV cables are third party tested and approved by BASEC. Educational establishments including schools, colleges and laboratories are some of the most prone structures to fire hazards The whole supply chain needs to take consideration of these areas where vulnerable people often move about such as children or elderly people in hospitals or care homes. The fire and rescue services may need a little more time than a conventional building including reading complex fire alarm information to ensure a safe rescue in the event of a real fire. Educational establishments including schools, colleges and laboratories are some of the most prone structures to fire hazards. This is due to ageing structures, high volume of combustible materials, and changing use in Science, Technology, Engineering and Maths programmes where more combustible and flammable liquids are being used. Concerns have been raised by architects and and designers about fire protection regimes  Sufficient Fire Risk Assessment  Recent research by the Fire Brigades Union, for example, showed that a key focus for all educational institutions must be ensuring that there is an effective fire risk management process in place, delivered by suitable and sufficient fire risk assessment carried out by an expert in the field. The best practice under Business Information Modelling (BIM) and all best practice of fire safety engineering methods should be observed in conjunction with project partners. There have been concerns over a number of years around the fire protection regime for new buildings expressed by the architects and designers themselves. The Royal Institute of British Architects (RIBA) points to the delays to Approved Document B with regard to the relationship of Building Regulations to changing design and construction. AEI Cables provides a full range of cabling products through its Total Fire Solutions service RIBA says the virtual disappearance of the role of the clerk of works or site architect and the loss of independent oversight of construction and workmanship on behalf of the client is a further issue for concern. In essence, RIBA believes that future proposals for the fire safety regulatory regime should be informed by the specialist fire safety expertise of relevant professional organisations and groups, and also take full account of this wider set of construction industry AEI Cables provides a full range of cabling products through its Total Fire Solutions service with the support of its parent company Ducab based in Dubai, with the design, manufacture and supply of MIC, Firetec Enhanced or Firetec Power depending on specific needs. The choice of cabling and accessories should not be underestimated at the earliest opportunity to ensure the fire and rescue services are given every chance of success in rescuing people and saving property.
