Edwards Signaling FIRE DETECTORS(49)
Edwards Signaling E-HD fixed temperature heat detector is an intelligent analogue device that can be configured as either a 135F fixed temperature heat sensor, or a combination rate-of-rise with fixed temperature. The heat sensor monitors the temperature of the air and determines whether an alarm should be initiated. The E-HD heat detector is capable of performing comprehensive self-diagnostics and storing the data. Due to its advanced thermistor technology, the E-HD detector is ideal for sensing fast, flaming fires and for applications where smoke detection is inappropriate. It is particularly well-suited to areas such as laundries and industries where fluctuations in ambient temperature is expected.Add to Compare

With many businesses and facilities re-opening sites following the Coronavirus lockdown, fire safety may not seem high on the list to other worries and responsibilities. But here, Mandy Bowden, Fire Business Development Manager at Comelit Group UK, led by fire industry bodies, demonstrates why it must be a priority, ensuring installation of systems is guided by best practice in accordance with the development, and fire safety measures are maintained and regularly tested to ensure compliance. Fire safety is too often neglected. And in the midst of returning to work and implementing necessary fever screening solutions and social distancing policies, it may even fall further down the necessary requirements, for businesses who are naturally eager to open and ‘get going.’ Providing Fire Safety But the Government and leading authoritative fire industry bodies have made it absolutely clear that, “Coronavirus is not an excuse for disregarding your responsibilities and businesses must ensure that they have an adequate amount of competent people to help in the implementation of both preventative and protective fire safety measures.” Above all else, fire detection is there to save lives; but the way in which systems are presented, will depend on their surroundings. For many facilities it involves more than the best choice of products and services. It also requires compliance to standards, currently changing in light of the Grenfell Tower Inquiry, and a need to consider the environment that it serves to keep safe. fire detection technology It is crucial that buildings are fitted with the highest quality life safety systems to ensure ultra-reliable protection Style of a fire detection system would be considered a priority for a hospitality environment, including hotel and restaurant facilities, to blend with the aesthetics and not impact on the ambience created. In any leisure facilities such as a Gym, it is essential fire detection measures and systems are in place that will provide customers, employees and the premises itself, with sufficient prevention against fire at all times. To keep up with demand, a system needs to be simple to install and operational as quickly as possible for the benefit of members and staff. However, a manufacturing vicinity will require latest fire detection technology to ensure the safety of its building, its specialist products and all personnel who operate on site. Similarly, an art studio is a specialist consideration when it comes to fire safety, especially with the use of different materials and substances in every day works by the artists on site. ensure ultra-Reliable protection Both temporary and permanent healthcare facilities in this period have undoubtedly been key to fighting the Coronavirus pandemic, and experienced an expediential increased demand for patient care. With more people to treat and protect, those working or residing within these spaces have to be considered at greater risk in the event of a fire emergency. It is crucial that these buildings have been and continue to be fitted with the highest quality life safety systems to ensure ultra-reliable protection. And the same is true for care homes, a vulnerable group in the fight against coronavirus. They require critical and reliable, functioning fire detection equipment that presents high performance protection, avoiding false alarms to prevent moving elderly residents unnecessarily. In each of these scenarios, the need to act quickly is paramount. Fire Detection Operations Fire safety must be kept a priority to ensure a return to work can occur seamlessly and successfully In healthcare, immediacy is a common theme through the industry, be it providing treatment or responding to a patient’s symptoms. This is no different in fire safety, with detection systems requiring an ease of use, by anyone operating on site. In businesses returning to work ‘post-lockdown’ the appointed Fire Marshalls and responsible persons may not be the ones returning to office locations, so others need to be trained with simple to operate solutions. In summary, fire safety must be kept a priority, arguably now more than ever to ensure a return to work can occur seamlessly and successfully, and with an obligation of care to workers coming back to operating establishments. By understanding these environments and choosing systems accordingly, duty holders can ensure they reduce risks across their premises and maintain a safe ‘new normal’. multi-Sensor detectors Comelit presents its FIA accredited family of ATENA and ERACLE fire detection and fire alarm systems, which offers a diverse portfolio of intelligent, addressable products that are feature-rich, easy to install, simple to operate and offer incomparable reliability.

2020 introduced a variety of unique challenges for many industries around the world. Not surprisingly, the fire detection industry was not immune to all of those challenges. However, as much of the global community defined our manufacturing and installing peers as “essential” or “critical” it required us, as an industry, to adapt so we could continue to service our customers with our products and services. Many regions around the world are experiencing significant demand for temporary detection systems. This demand is almost universally driven by an increase in education, awareness, and enforcement. While this is a global shift, our company has experienced a large demand in our own backyard. Within the United States, this is being driven by the adoption and enforcement of NFPA 241. NFPA is the Standard for Safeguarding Construction, Alteration, and Demolition Operations. NFPA 241 has been a “concept” since 1930 and the official text was finally adopted by the NFPA in 1933. As with all standards, it has progressed over the years to accommodate changes in technology as well as safety awareness. Fire safety awareness While general safety awareness on construction sites has always been consistently high, fire safety awareness has significantly increased within the last 5 years. Nuisance alarms negatively consume first responder bandwidth Typically, new, or increased regulation within our industry occurs after a single devastating event or several significant events. In this particular case, it was a combination of both. On a national level, fires on construction sites were reaching dangerous and unacceptable levels and becoming so widespread that enforcement of this standard became a priority in several states. Need for accurate and timely fire detection According to a report released by Richard Campbell of the NFPA in February of 2020 titled Fire In Structures under Construction or Renovation, “the estimated number of fires in structures under construction has increased since 2014 after declining between 2008 and 2010” further creating awareness. For the last few years, the focus of many local AHJ’s (authority having jurisdiction) was on new and active worksites or renovation projects. With the changes imposed by the COVID-19 pandemic today, many non-essential industries have either shut down or had their operations significantly reduced. This means the need for a functioning detection system is more critical now than ever as many facilities remain idle or continue to operate with reduced personnel. Detecting fires quickly and accurately gives our first responders the best chance of saving a person or facility. Conversely, having any “detection system” is often not good enough. Nuisance alarms negatively consume first responder bandwidth, possibly removing an engine or fire company from a genuine event. Temporary fire detection In an article by The Boston Globe, Easthampton Fire Chief David Mottor, president of the Fire Chiefs Association of Massachusetts said “Ninety percent of these buildings go up every day and nothing happens. It’s during construction before the sprinkler system is activated when they are most dangerous.” Globally, we have seen four approaches to temporary detection for both construction and renovation sites. We will quickly discuss the advantages and disadvantages below: Using 24/7 fire watch Utilizing local first responders or other authorized/trained personnel to offer 24/7 fire watch requires a person or team of people to be onsite 24 hours a day, 7 days a week to be physically looking for fires. Advantage: Someone is always on site, actively viewing and patrolling the facility. Disadvantage: Maintaining a 24/7 fire watch can be expensive, further the person or team can only see/find fires in proximity to them as they continue to move about a facility. Using digital linear heat detection Digital linear heat detection is a fixed temperature detector that is constructed using a twisted pair of metal conductors that are separated by a heat sensitive polymer. When the ambient temperature meets or exceeds the detector’s fixed temperature the polymers melt, and the detector shorts out resulting in an alarm. Advantages: Detector can be easily installed at a new construction site or a facility being renovated. The technology is a low profile, non-intrusive and cost-effective form of detection. This automatic initiating device is immune to environmental conditions. Protectowire FireSystems offers Confirmed Temperature Initiation technology (mechanical damage does not cause a false alarm). Disadvantages: Detector can be mechanically damaged during normal worksite operation. If you are unsure, be sure to check with the local AHJ or call your insurance provider Using wireless spot detectors There are a few companies on the market that offer wireless spot detectors that can be networked together. Advantage: Typically, this technology uses a mesh network of detectors. The detectors and their bases are battery operated and can be moved or placed per worksite requirements. Disadvantage: This technology can be expensive. Physical barriers on the construction site may hinder mesh network operation requiring the purchase of additional wireless units. Many wireless technology providers focus on smoke detection. Smoke detectors are often not ideal for the harsh environments associated with construction (dust, temperature changes, etc.). Using a hybrid approach This involves using wireless nodes to supervise linear heat detection. Most manufacturers of the wireless systems offer a wireless node that can accept a third-party initiating device. Advantage: Wireless nodes can be placed anywhere, and linear heat detection technology can withstand the harsh construction environment. Disadvantage: Wireless node battery life can be reduced when using a third-party device. Less cost-effective approach. Solution for Facilities While each of the approaches listed above has its own advantages and disadvantages, you must always consider what is best for your facility. If you are unsure, be sure to check with the local AHJ or call your insurance provider. Established in 1938, Protectowire FireSystems is the global manufacturer of Linear Heat Detection Systems. The Company has been manufacturing in the United States for the past 80 years and counting.

New government legislation due to come into force in the United Kingdom on July 1st will require electrical installations in privately rented properties to be tested and inspected at least once every 5 years. The Electrical Safety Standards in the Private Rented Sector Regulations (2020) will require landlords to enlist qualified electricians to complete inspections and provide certification to tenants – or face fines of up to £30,000. While the risk of fire can never be entirely eliminated, the new legislation will introduce higher levels of safety and ensure that one of the primary causes of fire – electrical malfunctions – is regularly tested for. There are a number of procedures and regulations in place for when a fire has already started, but this new law will help to reduce the chances of it getting to that point. After all, prevention is the best form of protection. No safety procedure or response plan will ever fully prepare someone for the reality of a fire. However, a comprehensive prevention strategy and use of the latest technologies to quickly detect and respond to a fire can at least reduce the potential risk to both life and property. Defensive detection A fire can spring from many sources. Current standards do a good job of ensuring properties are well equipped to defend against fires created by overcurrent caused by overloads and short circuits. A comprehensive prevention strategy and use of the latest technologies to quickly detect and respond to a fire can at least reduce potential risk However, electrical fires can also result from mistakes made during the installation process, namely loose cabling or aging circuits that will not be detected by overcurrent protection. Indeed, a defective or worn insulation is the cause of 14% of all electrical fires in buildings. The danger of landlords only performing the bare minimum to protect their buildings is that, should a fire start from a source they haven’t accounted for, the loss and disruption to property could be devastating. For maximum protection, individuals need reliable, innovative products that excel beyond the minimum standards to prevent a fire from starting in the first place. The pending legislation will add to this safety from the start. It will require landlords to use qualified electricians when installing, repairing and maintaining systems, benefitting both landlords and tenants by mitigating electrical issues and instilling greater confidence. Protection against insulation faults The risk of cable insulation faults grows over time and the consequences can be severe. Low-intensity arc faults are more likely to occur in humid, dusty environments, causing injury and deadly fires if precautions aren’t taken. Protection against insulation faults within cables can be assured by residual current devices (RCD), which are triggered by earth leakage currents exceeding 300mA. For maximum protection, individuals need reliable, innovative products that excel beyond the minimum standards to prevent a fire from starting Additionally, final circuits in critical locations (as recommended in IEC 60364), should be protected by an arc fault detection device (AFDD). This is a circuit breaker that automatically cuts off the electricity supply when it detects an arc fault in the circuit. By immediately stopping the supply, AFDDs stop arc faults from reaching temperatures where fires can break out. As well as ensuring that private tenants feel more safe and secure, the new legislation represents an opportunity for electricians to secure more work and develop their skills. Going forward, as the demand for electricians in the private rented sector rises, we expect to see greater opportunity for electrical engineers to win long running contracts with landlords and property managers. Fire may be a risk, but it is not unavoidable. This new legislation promises greater peace of mind for private tenants by ensuring that electrical standards are met and hazards reduced. With expert knowledge and the correct approach to electrical fire prevention, a fire can be extinguished before any damage is done.

Fire detection is reaching new, advanced levels, designed to help save more lives. Edwards, continuing in its legacy as the inventor of the alarm bell, is the first multi-criteria smoke detector manufacturer to receive certification to the UL standard for Fire Alarm Systems UL 268, 7th edition, set to take effect May 2020. The new Signature Optica smoke detectors utilise a next-generation sensor that better distinguishes the type of fire and the danger it creates, as well as reducing nuisance alarms. Edwards is part of UTC Climate, Controls & Security, a unit of United Technologies Corp. UL-certified Signature Optica smoke detectors The Edwards Signature Optica detectors will differentiate between truly threatening smoldering fires and nuisances such as burning food or steam The significantly revised standard incorporates three new tests, including a new cooking nuisance alarm test and two polyurethane foam tests for smoldering and flaming fires. These new tests better represent the smoke profiles and behavior of modern building fires to help ensure next-generation sensors are designed to give building occupants enough time to evacuate safely. All UL-certified smoke detectors are required to meet the enhanced requirements in 2020, representing a major change in the life-safety industry. The Edwards Signature Optica detectors will differentiate between truly threatening fast-flaming or smoldering fires and nuisances such as burning food or steam. The new detectors may also improve overall occupant safety, as commercial buildings typically contain furnishings comprised of synthetic materials such as polyurethane foam that are known to ignite and burn faster than traditional materials. This is a major advancement for commercial building operators, especially in hospitality, healthcare and other facilities that can be prone to nuisance alarms. Importance of multi-criteria smoke detectors “Through our research, we know that fire dynamics have changed over the last several decades,” said Chris Hasbrook, Vice President and GM for UL’s Building and Life Safety division. “We know manufacturers like Edwards have been actively working toward meeting the new smoke detector requirements and we are happy to see the first certification mark on a multi-criteria smoke detector. While expanding the smoke detector’s ability to respond to a range of types of smoke generated from various types of fires, today’s smoke alarm will be more technologically advanced and have the ability to help reduce cooking nuisance alarms, and that’s extremely important for fire safety.” The technology in Signature Optica represents a more sophisticated detection methodologyThe technology in Signature Optica represents a more sophisticated detection methodology. As particles enter the chamber, the size of the particles is analysed by a series of algorithms and consolidated into ratios to determine if the particles stem from a real fire or a nuisance source. This innovative approach was quickly matured using advanced design principles and the Edwards state-of-the-art fire test room. Signature Optica detectors can be retrofitted to existing Edwards systems without replacing control panels or software. Enhanced fire safety “Edwards is providing customers with the tools they need to alarm faster with greater accuracy, building on our 146-year legacy of fire and life-safety innovation,” said Edwards General Manager Angie Gomez. “The new Signature Optica smoke detectors will enhance protection of people and property while minimising false alarms that cause business interruption and unnecessary responses by fire departments.” In 2014 alone, according to the NFPA Journal, U.S. fire departments responded to 2.5 million false alarms. The Signature Optica detector line will become commercially available in the coming months.
