Det-Tronics Fire Detectors

Innovation in the fire protection industry can oftentimes be slow to move forward, particularly when compared to other similar industries. This is because legislation, regulation, and enforcement, while all necessary proponents within the sector, can often slow the tide of revolutionary ideas. However, the ability to innovate in this industry can quite literally be a matter of life and death. The developing intricacies of modern infrastructure and the demand for more sustainable solutions must also fuel the need for innovation. Fortunately, there are many companies at the forefront of technical and digital transformation within the industry. At the NFPA Conference in June 2019, much of the chatter revolved around Smart Connected Things (SCoT) within fire protection systems.  Smart Technology Smart Tech can offer more accurate, efficient inspections and testing, which on its own is capable of saving lives These systems are now being used by both building owners and service providers to determine fire protection system conditions as well as helping to perform some critical testing functions remotely - which of course has been invaluable in 2020. Smart Tech can offer more accurate, efficient inspections and testing, which on its own is capable of saving lives and protecting valuable property. For example, if a warehouse has been equipped with smart tech solutions to observe water pressure and flow rates within a building sprinkler system, users can have a real-time view of how much water has been flowing per minute. This means that should a fire break out in a particular part of the building the flow rate within the sprinkler can be routed to that specific area to put the blaze out as efficiently and as quickly as possible. Advanced Smoke Detection Fire protection brands have made huge leaps forward in their quest to develop smoke detectors which meet with the UL 268 Safety Standards for 2020. The new standard requires that all smoke alarms and detectors must meet two critical benchmarks: Increased responsiveness to the new polyurethane foam tests. Ability to distinguish the difference between smoke aerosols from accidental fire sources and smoke aerosols from cooking sources. Basically, domestic smoke detectors must be able to understand the difference between materials, based on the kinds of smoke they emit when they catch fire. Detectors must also distinguish between the smoke produced as a by-product of cooking, or a “nuisance” fire, and a real fire, which could pose a threat to human life. Smoke & Flame Video Detection The new alarms feature “TruSense Technology”, which is designed to be able to differentiate between fast and smoldering flames and common false alarms. These technologies were developed in the hope that homeowners wouldn’t just simply remove smoke alarms or batteries due to frequent false alarms. Video Image Smoke Detection technology has been around the industry for a few years now, but full video detection is now being used to supplement it, in order to further the applications of this technology. A video image will then be processed by the software that then concludes whether the clip contains smoke or flames This tech uses video-based analytical algorithms that integrate cameras into advanced flame and smoke detection solutions. A video image will then be processed by the software that then concludes whether the clip contains smoke or flames. The algorithms used to distinguish smoke and flames can utilize several different metrics, such as a change in brightness, contrast and movement. Water Mist Suppression Systems Depending on the kind of system in place, these recognition tools can even offer security and other surveillance features too. This technology is ideal in locations with large surface areas, such as power plants, stadiums, shopping centers and warehouses and distribution centers, where a fire may be particularly challenging to locate using traditional methods. Flame Video systems trace fire to its origin to make for quicker, more effective extinguishment and evacuation. A major concern for most businesses in any industry is sustainability. Water mist suppression systems are able to fight fires using significantly less water than a traditional system. The water is stored under extreme pressure and is released using specialized sprinklers and spray heads. This enables the water is able to reach a far larger surface area since the droplets are much smaller. Exit Point Technology A water mist suppression system is also designed to cool down an area where fire and smoke are present, by blocking radiant heat and eliminating oxygen from the origin point. These systems are often used in areas that see a lot of foot traffic or buildings where the possibility of water damage would be detrimental. All Fire Alarm Systems must include notification appliances, such as bells, horns and strobe lights. Technological advances use directional sound to help evacuees determine the pathway to the fire exits But the latest devices now provide verbal instruction on what to do in the event of a blaze and tell people where to go to the nearest exit. It’s highly likely that evacuation may be hampered by black smoke and smog in a real-life emergency. This obviously makes visibility limited, thereby possibly making exit signs challenging to see. The latest technological advances use directional sound to help evacuees to determine the location and the pathway to the fire exits. New Sealing Sprinkler Guidance The audible sound is specially adapted to the human ear, meaning that someone could easily determine the direction and sound. While the previous entries in this list have been about products, it’s also absolutely vital that fire safety regulations are also developed alongside these products. Not only does this ensure the protection of occupants within the building, but also the structure of the building itself. For example, The Ministry of Housing, Government & Local Government announced tweaks to the Approved Document B (Fire Safety) which went into effect last November and applied to building works that started this January. These updates apply to blocks of flats and mixed-use buildings with top floors that are more than eleven meters above ground level. The legislation change means that C-PVC sprinkler pipes now need to be sealed with only specialist and approved products. The height threshold for a sprinkler system in residential flat blocks has been reduced from 30 to 11 meters.

Since the Grenfell tower tragedy in 2017, residential high-rise fire safety has become a top priority for tower block building managers. If a high-rise building is found to contain combustible cladding, then the standard ‘stay put’ policy is no longer considered safe, and instead a temporary ‘simultaneous evacuation’ strategy must be put in place until the cladding issue is resolved. Currently a Waking Watch protocol is the preferred option for ensuring resident’s safety, in order to coordinate a simultaneous evacuation in the event of a fire. But, due to the extremely high cost of Waking Watch, Fire Detection & Alarm systems are being used to help reduce and, in some cases, remove these costs, which can amount to upwards of £100,000 per year. After the Grenfell fire, official figures showed that there are 300 towers with ‘Grenfell-style’ Aluminum Composite Material (ACM) cladding. However, there are many different types of high-risk flammable cladding used on purpose-built blocks of flats, such as timber, high-pressure laminate (HPL) and polystyrene cladding. With more and more unsafe buildings being assessed, the scale of this issue continues to grow. Currently a Waking Watch protocol is the preferred option for ensuring resident’s safety The UK Government announced in 2018 that it would pay for the removal and replacement of unsafe cladding in councils and housing associations. However, there is no legal position stating that private landlords should not pass the cost of this work onto tenants, and with the high costs of replacement, along with mounting Waking Watch costs, private landlords are known to pass this cost to tenants in service charges. Along with the cost of cladding replacement, landlords are also charging tenants for the cost of expensive Waking Watch services. Approved fire alarm systems are fast becoming the preferred safety system, due to the reduced overall costs, as well as the NFCC (National Fire Chiefs Council) recommending these over Waking Watch services. Fire safety regulations in high-rise buildings Following the Grenfell tragedy, the Government issued notice that all buildings over 18m had to be assessed for combustible material in their external walls. Following this, in January 2020, the government also issued Advice for Building Owners of Multi-story, Multi-occupied residential buildings stating that “building owners are to consider the risks of any external wall system and fire doors in their fire risk assessments, irrespective of the height of the building” immediately, until a Fire Safety Bill is put in place. Approved fire alarm systems are fast becoming the preferred safety system In order to assess the fire risk of external wall systems of residential apartment buildings an EWS1 assessment (External Wall Fire Review) must be completed. This risk assessment form provides a ‘safe’ or ‘unsafe’ certificate for the building, and must be completed by a competent fire expert. Not only does an ‘unsafe’ certificate affect the owner of the building, with the need for new fire safety solutions, it also directly affects tenants, with mortgage lenders refusing to lend on a apartment until they are satisfied that the facade is safe. Until the building has completed the assessment and been deemed safe, all dwellings within the building are valued at £0, and cannot be sold. 'Unsafe' certificates Buildings that have been awarded an ‘unsafe’ certificate through the EWS1 assessment will need to implement temporary fire safety measures while the cladding is being removed. The key purposes of this guidance, outlined by National Fire Chiefs Council (NFCC) in May 2018 and then reviewed in October 2020, are: early detection of a fire, warning of building occupants, and management of the evacuation. The measures state: In order to prevent tenants from being removed from their homes, ‘Stay Put’ must be temporarily replaced by a ‘Simultaneous Evacuation’ strategy until the building has been remediated. Temporary protection measures must be introduced to ensure the safety of residents; either a 24/7 Waking Watch or a common Fire Detection & Alarm system designed to BS5839 Part 1 category L5 specification. Fire safety solutions Waking Watch is the quickest and easiest way to fulfill the requirements from the NFCC guidance. This solution requires a trained fire marshal or warden to patrol the building 24/7 and alert residents in the case of a fire. They will also be responsible for carrying out the Simultaneous Evacuation strategy and assisting residents’ evacuation. While the Waking Watch solution works well as an immediate solution to fire safety, the mounting costs of this fix means that it is unsustainable in most situations, with tenants facing unaffordable increases to their monthly rent in order to cover the costs. For example, reports into Raphael House, near Essex, show how a five-person 24-hour patrol costs £50,000 per month. This cost is split between the 154 flats, resulting in average costs of more than £300 a month for each resident. Issues with Waking Watch In addition to the cost, there are other issues associated with Waking Watch, including: Patrols cannot cover all areas of the building at all times No fire detection system within the flats themselves Not a long term solution The alternative solution to fire safety in high-rise buildings, as per the NFCC guidance, is to install a Fire Detection & Alarm system designed to BS5839 Part 1 category L5 specification. Although the upfront cost of these systems tend to be higher than a Waking Watch initiative, the overall expenditure, given the cost and time it takes to replace the cladding, far exceeds the cost of a fire alarm system. NFCC compliant fire alarm systems An NFCC compliant fire alarm system ensures early detection of fire and alert to residents. The BS5839 Part 1 category L5 systems do not replace the mains wired smoke alarms required in each apartment, but instead are installed in the common areas of the building in order to provide additional cover for these communal areas. These fire systems should be: Designed in accordance with BS5839, Part 1, category L5 Heat detectors should be installed throughout the building next to the windows that overlook an area of the external wall, including within the dwellings. An immediate evacuation signal should be triggered by the operation of any single heat detector. Installation of a new common area fire alarm system should not cause any further damage to the compartmentation or have an adverse effect on other provisions in the building. Comparison (Waking Watch vs Fire Alarm Systems) Cost: The government has outlined the average cost of Waking Watch in England as £17,897 per building per month, with the hourly rate per person undertaking Waking Watch duties ranging from £12.00 to £30.00 per hour. A total of £644,292 over 3 years. Additional charges for equipment, facilities, accommodation and services can also be applied. A suitable fire alarm system is likely to cost around £65,000 over the course of 3 years, for installation and yearly recurring costs. This means, over this period, installing a fire alarm system will save a total of £579,292. Long term solution: While both Waking Watch and a Fire Alarm System are considered short term solutions, many fire alarm systems can be adapted for future use once the cladding issue has been resolved, providing suitable infrastructure is created at the design and installation stage. Alerting the whole building at once: A Fire Alarm System is a more time efficient solution to detecting a fire than Waking Watch. The system is able to alert the whole building at the same time, allowing for the simultaneous evacuation protocol to be followed in a more time efficient manner. The NFCC states in their Simultaneous Evacuation Guidance... “NFCC strongly recommends that where a change to a simultaneous evacuation is deemed appropriate and will be required for medium to long periods of time that a temporary common fire alarm system is installed. This is because a temporary common fire alarm, when designed, installed and maintained appropriately is a more reliable and cost-effective way to maintain a sufficient level of early detection. An appropriate communal fire alarm and detection system will generally provide more certainty that a fire will be detected and warned at the earliest opportunity rather than rely on using trained staff.” With many residential high-rise buildings needing additional protection due to flammable cladding, and the excessive cost of Waking Watch, now is the time to consider a Fire Alarm System to keep residents in high-rise buildings safe.

During these challenging times, it is more important than ever to protect the supply chain of food, including supermarkets and convenience stores in cities around the world. On average 3,740 fires occur in food and groceries stores in the US annually, including supermarkets and convenience stores, according to a report published by the NFPA (National Fire Protection Association). Structure fires in mercantile properties were responsible for the loss of 12 lives and more than $600 million indirect property damages, and this doesn’t account for the cost of business interruption and the effect on the reputation of the store. Many stores haven’t been able to recover after a fire. The report estimates that a single fire may cost $46,000 on average, which in hindsight is considerably higher than investing in a fire detection system. The most common causes of fire in supermarkets It’s important to look at the data from two different perspectives. The first is the number of fires by cause, and the other is to quantify the property loss by cause. The report estimates that a single fire may cost $46,000 on average Fires caused by cooking equipment , including stores with kitchens and warming and portable equipment, account for 21% of incidences, but only for just 7% of total property damage and four civilian deaths (firefighter and first responder deaths are registered on a different report). On the other hand, electrical distribution and lighting equipment malfunctions and defective wiring account for 15% of the total of fires in a given year, but caused $165 million in property loss, or 27% of the total recorded on the report. It is also important to mention that intentional fires are the third cause reported, accounting for 11% of the total fire incidences and 20% of the property loss highlighted in the report. Occupation, materials and risks The kind of store poses a significant variety of risks associated to the type of occupation, the number of occupants and the materials stored and available in the shopping areas. It’s possible to find combustible materials of diverse nature and propagation speed. Cardboard and paper wrapping can be found in all store areas, including book and magazine stands. Cleaning products, oils and fatty products might have a high propagation speed. All of this, surrounded by different kind of plastics, immensely increase the level of risk. Overall, combustible liquids caused 41% of the civilian deaths recorded during the report In my firefighting years I’ve responded to several fires in food supermarkets and distribution centers, and saw tuna cans (canned with oil) exploding and spreading flames to the surrounding areas. Regarding occupation, it is known that supermarkets and groceries stores are places with high levels of occupation, especially during working hours. But one interesting fact that the report found is that fires occurring between 9pm and 5am can cause, on average, $73,800 in property damage. The NFPA estimates that 21% of human life losses happened between 12am and 3am. This highlights the importance of installing and maintaining an automatic fire detection system. Installing fire detection And Protecting Your Store With the variety of materials and the risk level that can be found in this kind of environment, it’s necessary to take a holistic approach. Fire protection should be designed while considering several angles, from passive protection in all interior and exterior structures and cladding to active protection with sprinkler and clean agent systems, proper ventilation and smoke control and automatic fire detection and evacuation systems. On average 3,740 fires occur in food and groceries stores in the US annually Several detection technologies need to work in parallel, depending on the type of products stored, the environment and the expected level of occupation on the protected area. Store height and ventilation need to be taken into consideration and also the kind of lighting in some cases. Depending on the ceiling height, the shopping floor could be protected with beam smoke detectors. If the ceiling is below six meters, or the store shelves obstruct the beam, it’s possible to use spot type smoke detectors. The same approach can be taken for warehousing and storage areas, but here I would recommend multi-criteria detectors, with heat and smoke detection combined. localized protection As I’ve mentioned before, cooking areas have an increased level of risk, which calls for localized protection. Here, I would recommend multi-criteria (smoke/heat) detectors for areas where food is heated and served, and smoke/heat/Carbon monoxide detectors on cooking areas to avoid nuisance alarms caused by cooking smoke and steam. It’s important to mention that until this year it was possible to install heat detection in cooking areas, but the UL 268 7th edition that comes into effect in 2021 will require cooking areas to be protected with smoke detection, and smoke detectors have to be able to reject nuisance alarms caused by cooking smoke and steam. Smaller supermarkets and convenience stores usually have vertical freezers or horizontal open freezers. Here, electrical and mechanical failures can ignite fires, which is why it is important to protect the rear side of the freezers. I would recommend point-type smoke detectors, as photoelectric smoke detectors tend to perform better on smoldering fires. The report mentions that air conditioning equipment and electrical equipment can be sources of ignition as well. To protect A/C rooms and electrical rooms I would recommend combined smoke/heat detectors, or maybe even smoke/heat/CO to assure better detection and avoid unwanted alarms in these business critical areas. There is a type of photoelectric smoke detector that uses two different LED sources inside the smoke chamber. This technology, called Dual-Ray, allows the smoke detector to identify the particles inside the chamber by size. The detector knows if it is sensing dust or steam, and can even differentiate between cooking or cigarette smoke from actual smoke from a smoldering fire. Bosch Building Technologies first introduced dual Ray technology in 2015. protecting the food supply chain During these challenging times, it’s more important than ever to protect the food supply chain and avoid the social and economic impact of fires in food stores, especially in impoverished areas. Supermarkets and convenience stores present a variety of challenges regarding fire protection, which calls for a holistic approach where passive and active protection are equally important. To achieve this target, one key element is automatic fire detection. Smoke and heat sensing technologies must be combined, and one size-fits-all approach is not enough. Detection and effective evacuation are critical to protect lives and minimize property loss.

AAR MRO Services supports airline operators with everything from maintenance inspections and equipment upgrades to airframe painting and heavy maintenance for all major aircraft in service. The largest MRO operator of its type in the Americas, AAR recently opened the company’s largest facility, located at the Chicago Rockford International Airport. Here, each of two 10-story hangar bays can accommodate hundreds of ‘small’ aircraft, two Boeing 787s or even an Airbus A380, the largest commercial aircraft in production today. Also in each of the two bays are 10 Det-Tronics optical flame detectors that function as the critical sensors for the AAR hangar’s fire protection system. Heavy Maintenance Inspections Aircraft spend anywhere from three days to two months in AAR’s hangars Russel Daubert, AAR Rockford’s Facility Manager, and Chris Wolf, Director of Maintenance, have overseen the 24-hour operations at the MRO hangar since it opened in late 2016. AAR serves multiple airline customers, and like any MRO facility, Wolf says their goal is to “get lines that are current, which means an airline operator will continually bring in one plane after another to keep their fleet operating safely.” Daubert adds, “The biggest portion of our work is airframe overhauls and heavy maintenance inspections, and depending on the aircraft, we can have up to 225 aircraft in each hangar at one time plus 50 to 60 crew.” Aircraft spend anywhere from three days to two months in AAR’s hangars. Fire protection in MRO hangars must be able to handle the challenges associated with servicing aircraft. Conventionally Constructed Fire Hangars According to Wolf, aircraft bring inherent fire hazards to MRO facilities. “These aircraft come in with 70,000 to 80,000 pounds of fuel,” Wolf says. “Add the oxygen tanks on board for passenger and crew safety, plus the possible sparks from electrical equipment or other sources, and you have all the ingredients needed for fire.” Maintenance also involves painting aircraft in the hangars, which can result in the circulation of highly flammable paint plumes under and around wings and fuselage. Hangars in these groups usually require both sprinklers and foam for fire protection Fire protection standards specific to aircraft hangars are spelled out in the National Fire Protection Association’s NFPA® 409 Standard on Aircraft Hangars. This document classifies hangars by size and construction type; conventionally constructed fire hangars with fire areas of 40,000 sq. ft. or less are classified in Groups I, II and III. Hangars in these groups usually require both sprinklers and foam for fire protection. High Expansion Foam Suppression System AAR’s Rockford facility is unique both for its immense size and for its construction method, a fabric tension membrane over steel trusses. The 2-inch thick insulated material meets NFPA 701 and ASTM E-84 standards for flame retardancy, fire safety advantages that led the NFPA to decide hangars covered in this fabric would fall in a Group IV classification. Group IV hangars can have an unlimited fire area and need only a low- or high expansion foam suppression system. One of the goals of MRO service providers is to provide fast turns of the planes entrusted to them by airline operators. To support this objective, a hangar fire detection system must have two very important capabilities: quickly detect the presence of flames, and reject false alarms (generated by welding, engine start-ups, etc.) that could unnecessarily initiate suppression systems, interrupt operations and potentially lead to significant aircraft damage. Fire Protection System The project manager for the Chicago Rockford hangar expansion looked to local fire protection contractor The solution for hundreds of hangars in the past 10 years – from military bases to commercial hangars and MRO facilities – has been to deploy optical flame detectors from Det-Tronics. When it was time to specify the fire protection system for the mammoth hangar bays, the project manager for the Chicago Rockford hangar expansion looked to local fire protection contractor, Absolute Fire Protection, Inc., to handle the fire protection system. In turn, John Danis of Absolute called in 3S Incorporated, a Harrison, Ohio firm that specializes in industrial and special hazard systems, to design the detection and foam suppression part of the fire protection system. Because of the size and scope of the Rockford hangar, 3S and Absolute, along with other design and building partners, worked for nearly three years to take the project from initial planning to construction. Multispectrum Infrared Flame Detectors During that time, a construction engineer had calculated it would take no less than 84 detectors per hangar bay to monitor the facilities for fire. Aaron Hinkle, sales engineer at 3S, disagreed. “I realized that was far more than necessary, if we just picked the right product for the job,” he says. All the alarms contractor had to do was install four detectors on each side wall" Hinkle had worked with the Det-Tronics X3301 Multispectrum Infrared (IR) flame detectors on previous hangar projects, and he knew the units possessed the optical power, field-of-view capacity and speed to do what was required. In consultation with Det-Tronics applications engineers, Hinkle came to the conclusion that, “Because of the X3301’s performance attributes, each 119,000-square-foot hangar could be covered with just 10 detectors from Det-Tronics. Using just ten detectors per bay greatly simplified the work,” Hinkle explains. “All the alarms contractor had to do was install four detectors on each side wall and two on the back wall. The front wall is the giant door that opens up to allow the craft to enter and exit.” False Alarm Rejection There were considerable cost savings in equipment and related hardware, as well as labor savings due both to the small number of units to be installed and the fact that the X3301 detectors could be placed at a much easier-to-reach height of just 8 to 10 feet off the floor rather than near the top of the 10-story hangar bays. To maximize false alarm rejection, X3301 flame detectors are programmed to run in Det-Tronics® Hangar Mode™, an option that incorporates a delay mechanism. The mechanism extends the processing time to react to fires, letting the detector distinguish between an actual fire and an event like a short duration auxiliary power unit startup. The operation mode has no effect on detection ranges or field of view, but can prevent an innocent action (such as a crew firing up gas heaters to stay warm) from resulting in an unwanted foam dump. Foam Suppression System AAR’s foam suppression system has gone off only once, and that was intentional An impressive demonstration to date, AAR’s foam suppression system has gone off only once, and that was intentional. To certify that the new system was working properly, Absolute, 3S and other suppliers commissioned the overall protection system by simulating an actual fire suppression event. They recorded it on video, and it’s a stunning sight. Daubert, facility manager for the AAR hangars, was delighted when he saw the video. “Within seconds of being triggered, foam erupts from dispensers in the ceiling. In no time, it has put a layer on every inch of the hangar’s floor. Within 3-and-a-half minutes, the foam has stacked up to a 10-foot depth, smothering any possible fire.” “I had never seen a system of that magnitude before,” Daubert continues. “Seeing just how fast we could stop a fire from spreading and put it out was pretty impressive. Thanks to the Det-Tronics detectors and the system’s other components, it’s obvious our hangar is well protected from the dangers of fire.”

Det-Tronics has introduced a new high-speed deluge module (HSDM) for the Det-Tronics Eagle Quantum Premier (EQP) fire and gas safety controller. The HSDM expands the capability of the EQP so it can activate ultra-highspeed suppression systems for high-hazard applications such as, but not limited to, munitions manufacturing. Det-Tronics, a provider of fire- and gas-safety systems, is a part of Carrier, a global provider of innovative heating, ventilating and air conditioning (HVAC), refrigeration, fire, security and building automation technologies. The new Det-Tronics HSDM meets today’s standards for an ultra-high-speed detection and releasing system. ultrahigh-speed detection The EQP safety system is FM Approved with the HSDM, making it capable of ultra-high-speed response According to the National Fire Protection Association (NFPA) Standard for Water Spray Fixed Systems for Fire Protection (NFPA 15), ultrahigh-speed detection and releasing systems must be capable of response in 100 or fewer milliseconds (ms) from the presentation of energy source to flow of water from the deluge nozzle. NFPA 72 National Fire Alarm and Signaling Code requires that releasing devices for suppression systems shall be listed for use with releasing service alarm control units. A listed fire alarm system has all components performance-certified both individually and as an assembled system. As an ancillary component of the EQP, the new HSDM is hazardous-location rated by FM Approvals, CSA, ATEX and IECEx, has SIL2 and DNV-GL approvals, and is CE marked. code-compliant system In addition, the EQP safety system is FM Approved with the HSDM, making it the industry’s only listed flame detection and releasing system capable of ultra-high-speed response. “After over 35 years of serving this industry, we are very excited about the release of a new high-speed deluge module as part of our ultra-high-speed system offering,” said Michael Hosch, product manager, Det-Tronics. “This new solution allows us to offer a code-compliant system that is listed and meets the current applicable standards for ultra-high-speed detection and releasing systems.”

The X3302 multispectrum infrared flame detector (X3302) from Det-Tronics is now third-party approved for the industry’s field-of-view for hydrogen fires, as well as approved for methane, methanol and synthesis gas (syngas) fires. Det-Tronics, a global provider of fire- and gas-safety systems, is a part of Carrier, a global provider of innovative heating, ventilating air conditioning (HVAC), refrigeration, fire, security and building automation technologies. The X3302 flame detector’s enhancements include third-party certification to detect a 30-inch (76 cm) hydrogen plume fire at 125 feet (38 meters) on-axis in as little as three seconds, a 25% improvement in on-axis detection range over the previous design. false alarm rejection In addition to being certified SIL 2-capable and performance-certified to FM 3260 for hydrogen fires, the X3302 is now FM Approved to detect methanol, methane and syngas fires, which contain a mixture of 53% hydrogen, 24% methane, 11% nitrogen, 8% carbon monoxide and 4% carbon dioxide. Other certifications include CSA, ATEX, IECEx, INMETRO and California State Fire Marshall. Additional global certifications are pending. Customers will appreciate that the X3302 is easy to install and maintain, which reduces total operational costs" Recently, gas streams for turbine power generation have transitioned to mixtures of hydrogen, methane and other gases. The X3302 can provide fire protection for these applications without requiring supplemental hydrocarbon flame detectors. The X3302 flame detector is also suited for hydrogen storage, aerospace, battery rooms, refining and filling stations. The X3302 flame detector has a patented detection algorithm, heated optics and signal processing features which increase false alarm rejection. Automatic Optical Integrity The patented Automatic Optical Integrity (oi) feature, an automatic calibrated performance test that is conducted once per minute, verifies complete operational capabilities. The detector will declare a fault if it loses more than 50% of its original detection range, proactively alerting operators to a potential loss of fire protection. “We are excited to offer the X3302 with expanded detection capability that addresses the need for reliable, fast multi-fuel fire detection at greater distances,” said Michael Hosch, product manager, Det-Tronics. “In addition to its enhanced functionality and safety record, our customers will continue to appreciate that the X3302 is easy to install and maintain, which reduces total operational costs.”
