Located on the shore of Italy’s beautiful Lake Como, Castello di Urio is a hotel and conference centre that is steeped in history. When it needed to upgrade its life safety system without affecting the structure of the building, the owners decided to use wireless fire detection technology from Notifier.

Agile wireless fire detection system

Castello di Urio is now a 150-room hotel and conference centre, and a meeting place for people from all over the world who come to enjoy the surrounding area and walk in the vast English garden that it is famed for. Managed by the Le Magnolie Association, the welfare of staff, guests and visitors at Castello di Urio is taken very seriously and recognising that the existing fire detection system was nearing the end of its life, it decided to invest in a new life safety infrastructure.

Domenico Magnani Quantity Surveyor, Soc. Cooperativa BaSE a r.l, explains: “We needed to avoid any disruption to the day-to-day operation of the business, prevent disturbance to the fabric of the building and, just as importantly, ensure that the new system was both reliable and cost effective. After assessing the available options we decided to implement the Agile wireless fire detection system from Notifier.”

Reliability, ease of use and cost effectiveness

The use of wireless based fire detection technology has grown massively in recent years and has proven to be particularly suitable for use in hotels, where installation flexibility and high levels of business continuity are all prerequisites and access can be an issue.

A correctly designed, installed and maintained fire detection system is vital when it comes to effective life safety" “Hotels and conference centres like Castello di Urio are usually unfamiliar environments for guests and visitors, who have little awareness of evacuation routes and fire safety regimes,” comments Alessandro Folli, Product Manager at Honeywell. “Therefore, a correctly designed, installed and maintained fire detection system is vital when it comes to effective life safety. Wireless fire detection systems have seen huge improvements over the past 20 years in terms of their reliability, ease of use and cost effectiveness – attributes that make them the ideal life safety solution for hotels.”

Product compliance standards

Wireless fire detection systems must comply with EN 54-25, which ensures that they provide the same level of protection as their hardwired counterparts. This standard specifies the requirements for how wireless systems operate, such as communication, redundancy through dual battery back-up, minimum battery life, improved fault monitoring and defined product testing procedures. Each device must be marked with the number of the standard, the name of the manufacturer, the model, a CE mark and the notified product certification body number.

Site survey

Even though product quality should be given due consideration, perhaps the most important element of any wireless fire detection system installation is a site survey. This process and must be thorough and comprehensive, as much of the subsequent configuration will depend on the results. Previously, this process was only achievable by visiting a site, however, software tools are now available that allow the user to design and simulate the quality of the wireless network from a remote location. Building plans can be easily imported via the software as images or computer aided design (CAD) files and networks can be easily tested to identify critical communication links.

All survey results should be recorded and data should include signal levels relating to all the radio devices and the background noise level, and confirmation that these signal levels are in compliance with the manufacturer’s recommendations. In the case of a networked system, this should also include the signal levels for the radio links between panels.

Delivering and installing a simple, integrated solution

Wired systems can be challenging to install, labour intensive and, of course, require the extensive use of cabling. Therefore, at Castello di Urio this type of system was out of the question.

Addressing many of the concerns traditionally levelled at wireless based systems, Agile offers unmatched levels of communication reliability and installation flexibility" Alessandro Folli, Product Manager at Honeywell states, “Addressing many of the concerns traditionally levelled at wireless based systems, Agile offers unmatched levels of communication reliability and installation flexibility, providing a robust and efficient method of delivering an integrated solution with greater simplicity and scalability”.

Castello di Urio’s walls and general layout would have made it difficult for a typical wireless fire detection system to provide the requisite level of protection. In stark contrast to a star network, where wireless devices are in direct communication with either a central wireless gateway or a repeater, and can be blocked, Agile’s platform is built on powerful, patented mesh technology that uses multiple communication paths to minimise interference and maximise system robustness.

 

Agile’s multichannel frequency diversity

EN 54-25 requires wireless systems to conform to three specific areas – site attenuation, alarm signal integrity and interference immunity. Agile’s multichannel frequency diversity ensures that these requirements are met.

Alessandro Folli says: “Multiple connection paths between each transmitter and receiver allow continuous, bidirectional communication. If a connection path is broken, the mesh network automatically re-routes the signal, providing a secure and uninterrupted network. Each device acts as an independent router, allowing for multiple communication paths and the Agile system is designed so that if one link is broken, all of the devices continue to communicate with each other without any loss of coverage. Furthermore, the ability to switch between as many as 18 radio channels and two antennas per device provides greater tolerance to interference, improving overall system effectiveness”.

Agile's IQ design software tool

Anyone that has had to evacuate a hotel in the middle of the night will understand the negative impact such an event has on customer satisfaction.

In addition to the unnecessary intervention of personnel and high costs of having the fire and rescue services attend, the loss of revenue, wasted food in restaurants and reputational damage should not be underestimated.

Regular maintenance can identify issues in advance and the Agile IQ design software tool has a diagnostic function that provides a real time picture of the network status that can identify any faults at Castello di Urio. Furthermore, Agile’s monitoring technology accurately predicts battery status, reducing unplanned maintenance requirements and eliminating the need to replace batteries on every inspection.

Immediate visibility and safety

Configuration of the network infrastructure and the fire detection system components was achieved on schedule, which is even more impressive given that it was the first time that our systems integrator had installed the Agile solution” Domenico Magnani, Quantity Surveyor, Soc. Cooperativa BaSE a r.l, says “Castello di Urio required full uptime while the Agile system was being installed, so work was phased so that at no stage were we without fire protection. Configuration of the network infrastructure and the fire detection system components was achieved on schedule, which is even more impressive given that it was the first time that our systems integrator had installed the Agile solution”.

At Castello di Urio more than 250 optical wireless detectors, 30 manual call points and 11 gateways have been installed, networked to the Honeywell control panel situated in the building’s reception area. It is now has a fully zoned, addressable system that gives immediate visibility across the estate.

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.
