When Salford Reds made their debut in their newly opened rugby league Stadium last December, it was the beginning of a new era for the club and its fans. Behind the scenes, numerous contractors and officials had been planning and building towards the premier game in the brand new £16m City of Salford Stadium.

The opening fixture marked the start of fire industry experts; Gent by Honeywell’s first commercial UK site to be installed with the company’s recently launched D1 rack based voice alarm and Public Address (PA) system. This was fitted alongside a Vigilon fire alarm solution in order to protect the Stadium, staff and fans.

D1 Voice Alarm/Public Address system

Tate worked in conjunction with Gent, selecting the company’s latest innovative D1 voice alarm/PA system

Wigan-based safety and security specialists, Tate Security Technology Limited, one of Gent 24’s of Approved Systems Integrators, managed the installation, from the initial design stages right through to commissioning and completion. Tate worked in conjunction with Gent, selecting the company’s latest innovative D1 voice alarm/PA system as the most suitable solution for the Stadium.

Steve Hutchinson, Sales and Development Director, Tate Security Technology, explains, “Discussions about this project began almost two years ago and we have worked closely with the major key partners and the main contractors, supply team on the project since then. We were brought in during the early planning stages to do the full detailed designs based on the Stadium’s construction drawings.

Turnstile entry counting systems

Tate Security Technology Ltd has more than 30 years’ experience working in the UK stadia market. The company has worked closely in the early years of Stadia Safety with the government and the Football League Association and has pioneered new methods of crowd control, Turnstile entry counting systems and including exit gate release, which now forms part and parcel of every major Stadium in the country.

Steve Hutchinson continues, “We chose the Gent system purely because of the quality of D1 voice alarm/PA and the fire alarm product. Gent has an extensive range of fully compliant equipment available to be installed in the market place and what better way to do that than within a brand new Stadium facility.

Vigilon voice alarm systems

The main part of the project started at the end of August 2011 and was completed earlier this year following a series of successful ramp events, including the Salford Reds opening rugby league game in December.

The Gent solution selected for the project was a fire alarm and D1 Public Address/Voice Alarm system that is fully compliant with the relevant standards for sports stadiums, and meets all of the requirements of EN54 parts 16 and 24. Gent’s Vigilon voice alarm systems were among the first to be certified with BRE, in line with the newly harmonized part 16 of EN54.

Networked addressable control panels

City of Salford Stadium system comprises four Vigilon networked addressable control panels, with nine detection loopsThe system in place at the City of Salford Stadium comprises four Vigilon networked addressable control panels, with nine detection loops in total. The D1 voice alarm/PA system, designed specifically for the venue, is a large rack based system comprising three 42u racks and a 19 zone voice alarm/PA system, providing a total power output of 13,000 watts to the loudspeakers throughout the Stadium.

Steve Hutchinson explains how the system works, stating “The cause and effect strategy of the D1 voice alarm/PA system for the whole Stadium changes according to whether there is a match taking place. The system was programmed to meet both building control and the fire strategy to enable two different modes.

High quality communications system

One operates during the games to protect the Stadium and its supporters, providing a high quality communications system and the other can be used on a day to day basis, when there is only the club staff occupying the ground.

The Gent system has been programmed to enable both non-event mode, used on non-match days, and full event match day mode to provide individual zoned areas with phased announcements and evacuation procedures. There are three microphones in total: A fireman’s microphone in the control room; a 19 zone paging microphone in the match day control room; and a 19 zone paging microphone in the DJ room.

Flexible, controllable stadium PA system

The Stadium public announcement system is both flexible and controllable used solely for providing audible messaging to any one of the Stadium’s individual zones. On non-match days the multi zone desk microphone station in the Stadium’s reception area is used to page the ground and office staff. On match days, the D1 voice alarm/PA system gives input into the Stadium’s DJ for background music, scores and general crowd announcements. The control aspect means this can be overridden if there is a need to evacuate.

The Stadium was initially built with a 12,000 capacity, with plans to extend to accommodate up to 20,000 over time. The site includes built-in offices, player facilities, hospitality boxes, concessions, community resources and two community outdoor sports pitches available for business and public hire. The main Stadium area has four covered stands for supporters.

Detailed acoustic modeling

Gent’s technical support team worked closely with Tate Security Technology to play a key part in the rack design

Gent’s technical support team worked closely with Tate Security Technology and played a key part in the rack design, the acoustic modeling and the Stadium speaker mapping. Gent’s detailed acoustic modeling provided in-depth prediction and results in Sound Pressure Level (SPL) distribution and STI results. The whole arena had to be acoustically modeled to ensure it complied with the requirements of BS5839 part 8 2008 and reach the specific audibility levels.

The requirements state that the results have to be at least five decibels above the Stadium’s ambient background noise and the Gent system delivers an SPL of 105 DB and STI results of 0.5-0.55.

Gent technical support services

Steve Hutchinson continues, “It is very difficult to predict the ambient noise levels in stadiums, as it’s often down to the individual design of each stand. The input from Gent’s technical support team was invaluable as their expert mapping enabled us to accurately predict the SPL distribution to give us equal sound as well as meet the minimum requirements across all four stands.

The Gent support services team was set up with the aim of providing expert support in acoustic design, as well as additional support for customers on any aspect of fire detection and alarm products. The team carries a vast amount of experience in the design and application engineering of FD&A and voice alarm/PA systems and can provide advice on everything from site survey and training, to general application guidance.

Factory Acceptance Test

Gent has recently created a new customer friendly D1 rack build area in the company’s extensive Leicester production facility to offer an expert rack build service with a dedicated Factory Acceptance Test area (FAT). The FAT area demonstrates how the rack is configured before it is sent to the site. All racks are built and programmed to a specification and the rack is shipped after it has been witness tested.

Gent’s Kevin Cooper, support services manager, added, “We are delighted that our first commercial installation of the D1 voice alarm/PA system has been so well received by both Tate Security Technology Ltd and the City of Salford Stadium. Gent is one of only a small number of companies that has received the new certification for the voice alarm range last year and this, together with our highly experienced customer service team, has made us the winning choice for fire detection and voice alarm/PA systems. We are proud to be playing our part in protecting the Salford Reds supporters and staff.

How Technology Helps London Fire Brigade With Incident Command
How Technology Helps London Fire Brigade With Incident Command

Drones give Incident Commanders an aerial view, increasing their situational awareness of fires and helping them to develop tactics to tackle them. Station Officer Lee Newman details how the technology was implemented by London Fire Brigade and the continued benefits. Identify external risks The Grenfell Tower fire has resulted in revisions to several operational procedures and the introduction of new equipment within the Brigade. A few months after the fire, the Brigade was tasked with setting up a trial to test the feasibility of having a drone capability to identify external risks and assess building stability at incidents, providing essential safety information that could facilitate ongoing internal firefighting operations. Implement the use of drones The Brigade implemented the use of drones and acquired a Matrice 210 V1 and a Phantom 4 Working with partners who had an existing drone capability, as well as drone experts, the Brigade began work to implement the use of drones and acquired a Matrice 210 V1 and a Phantom 4 as a trainer and reserve drone. In the summer of 2018, an Emergency Services bespoke course was run by Essex Police to train the Brigade’s team of drone pilots, who were all PfCO qualified within one week. From start to finish, it took just nine months to get London Fire Brigade’s drone team operational. Working of the drones On its first day of being available for incidents, the team received an order to attend a 15-pump fire at a leisure center, which was under renovation. They were asked to confirm if there were cylinders on the roof of the building and immediately put the drone to use. The team flew and relayed the camera footage onto a large screen that was fitted into a van provided for the trial. The drone footage was able to identify, to the Incident Commander’s satisfaction, that the cylinders were actually rolls of asphalt due to be laid on the roof as part of the renovation. If the drone concept could have proven its use in one job, this was it. The information from the drone allowed the Incident Commander to decide not to make it ‘cylinders confirmed’ and saved a lot of unnecessary extra appliance movements. Applications of drone Since that first callout, the team has been to around 300 incidents of six pumps or more, including persons in the water, fires, and various missing people’s incidents both in London and into other counties, assisting police forces. From start to finish, it took just nine months to get London Fire Brigade’s drone team operational Drone inventory The Brigade’s drone capability inventory includes a Matrice 300 with an H20T dual thermal and optical camera; a DJI Mavic 2 Enterprise Dual with multi attachments; a Mavic Air 2 and a Yuneec 520. The Brigade also has a Teradek live streaming device and multiple tablets for receiving the streamed footage. The Brigade operates with two Mitsubishi Outlander PHEVs – plug-in hybrid SUVs – and has split the drone equipment into two, with one vehicle carrying the drone and batteries, and the other carrying all the support kit and ancillaries. Working in dark conditions The drones are permitted to fly up to 400 ft above ground level or higher in an emergency and can fly as fast as 50 mph. They also can act as a loudspeaker to give instructions or reassurance and shine a bright spotlight in dark or low light conditions. 24/7 service The Brigade has eight pilots trained and operates a 24/7 service The Brigade has eight pilots trained and operates a 24/7 service. The team is working closely with its blue light partners, including the: Metropolitan Police Service, several search and rescue teams, and a host of fire services surrounding the capital, as well as giving advice to other upcoming drone teams around the UK. Use of drone in future The Brigade’s drone capability has been molded to how it sees the future and what it holds in the way of drone use. For example, the Brigade has developed a capability to drop water rescue aides to people at water incidents, which helps to keep them afloat long enough to be rescued. The drone can also be used alongside the swift water rescue teams to provide situational awareness of hazards and the resulting risks during the rescue phase. Delivering fire escape tools The Brigade also invested in fire escape hoods in late 2018 and has already demonstrated how one might be delivered via a drone to a balcony above the height of an aerial appliance while using the Mavic Enterprise 2 to relay instructions via the loudspeakers. These possible new uses are pushing the boundaries of the Brigade’s original concept and demonstrate how London Fire Brigade works to stay ahead of the curve. 

Chicago Bans Dogs From Firehouses, Despite Long-Held Tradition
Chicago Bans Dogs From Firehouses, Despite Long-Held Tradition

There is a long tradition of canines in the fire service, from Dalmatians riding shotgun in the fire truck to mixed breeds rescued from fires that later become the fire company mascot. The tradition has taken a hit recently in Chicago, where dogs are no longer allowed at firehouses after one station dog killed a smaller breed canine near a firehouse in the Englewood neighborhood. The incident The firehouse dog in Chicago, named Bones, was a mixed breed stray rescued off the street that was living at Engine 116 at 60th Street and Ashland Avenue. A neighbor was walking her smaller breed dog past the firehouse and watched in horror as Bones attacked and killed her small dog. After the incident, Chicago’s Acting Fire Commissioner Annette Nance-Holt issued a department memo: “Any and all prior permissions for dogs in the fire stations or on fire apparatuses are hereby revoked … effective immediately.” Chicago Firehouse dogs Most of Chicago’s firehouse dogs are strays that were picked up and brought to firefighters by the public. Fire crews and paramedics care for the dogs, train them, feed them and get them inoculated and spayed or neutered, then ask formal permission to keep the dogs on site. Historically, permission has been granted, in effect saving the dogs from being euthanized. Breed of choice The tradition of dogs and the fire service goes back centuries, to the 1700s, when carriage dogs first trotted alongside horse-drawn fire carriages. Dalmatians were the breed of choice, given their good temperament, calming effect on the horses Dalmatians were the breed of choice, given their good temperament, calming effect on the horses, and grace under pressure. The Fire Department of New York (FDNY) began utilizing Dalmatians as early as the 1870s. Dalmatians as firehouse ambassadors When motorized vehicles came on the scene, Dalmatians were already associated with firefighters, who continued to keep them on-site as firehouse residents and mascots. Increasingly, Dalmatians and other dogs became public ambassadors for firehouses and were involved in public education about fire safety and emergency preparedness for school and community groups. For example, Sparkles the Fire Safety Dog, a Dalmatian from Clarksville, Ark., was a character in her own set of children’s books about fire safety and traveled around the country teaching children about fire tips. reduce stress, provide comfort Currently, firehouse dogs are other breeds, too, many rescued from house fires or other tragedies. Firehouses often adopt dogs, who become symbols of resiliency, bravery, fortitude – and provide comfort and companionship for firefighters who face high levels of stress on the job. After the 9/11 attacks, two firefighters from Rochester, N.Y., gifted the FDNY Ladder 20 company a Dalmatian puppy, appropriately named Twenty. The dog served as a source of comfort to the firefighters, who lost seven members of the company in 9/11. Dogs recognize signals Taken in as a stray in 1929, a dog named Nip served 10 years with New York’s Engine Company No. 203. During his service, the dog was injured by broken glass, falling debris, scalding burns, and bruises from falling off the fire engine. Nip could recognize all bells and signals. On fire scenes, Nip could alert firefighters if he knew something was wrong and sometimes run into burning buildings to look for victims. Unfortunately, Nip was killed by a hit-and-run driver in front of the firehouse in 1939 (and was stuffed by a taxidermist and displayed at the firehouse until 1974). Dogs promote fire safety Dogs promote fire safety outside the firehouse Dogs also promote fire safety outside the firehouse. For example, accelerant-sniffing dogs are trained to detect minute traces of accelerants that may be used to start a fire, according to the State Farm Arson Dog Program. The special bond between firefighters and dogs is the stuff of legend, despite the recent unfortunate events in Chicago – an ignoble scar on a long, colorful history of dogs in the fire service. Hopes remain that the decision can somehow be reversed, based on social media postings. “This is the first tragedy I have heard of in … 25 years,” said the administrator of the Firehouse Pups group.
