Nittan Europe, UK manufacturer of conventional and addressable fire detection products and systems, has had its Evolution analog addressable fire detection system installed into a new student accommodation development in Beeston, Nottingham. The system was installed by Nottinghamshire based integrated safety and security solutions provider, TIS.

Dagfa House is a unique development of townhouses, clusters and studios adjacent to The University of Nottingham campus. It provides accommodation to 229 students and a range of leisure and study amenities. At the heart of the development is a Grade two listed building that dates back to the 18th-century and was converted into a school in 1948.

Addressable fire alarm system

This latest development has been undertaken by the Cassidy Group, which has over 30 years of experience in construction and property. One of the key fire safety challenges posed by the Dagfa House development was the mix of accommodation blocks, with some being relatively small. A cost-effective fire detection system was required that could potentially evacuate each site in the event of a fire and that would also be future proof, with spares readily available.

A Nittan Evolution analog addressable fire alarm system, comprising two individually networked systems, each utilizing eight Evolution1 panels and Nittan devices was chosen as the solution. Chris Mills, Head of Fire Division at TIS explains: “TIS carried out market research of a number of fire alarm manufacturers before finally settling on the Nittan Evolution panel with Nittan devices which provided a single source approach while providing a cost effective and reliable solution.”

Sophisticated detection algorithms

Evolution uses ASIC technology in the sensors and sophisticated detection algorithms

Evolution is Nittan’s advanced, premium fire system. Evolution uses ASIC technology in the sensors and sophisticated detection algorithms, combining extremely reliable fire detection together with a very high degree of protection against unwanted false alarms. Its advanced, highly flexible protocol allows for substantial amounts of information to be transmitted at high speed and is not affected by the number of devices on the loop.

At Dagfa House, the Nittan Evolution1 Panel was selected because of its built-in network connectivity, making it extremely cost effective, plus its ease of installation and cause & effect configuration. For the primary detection in the majority of locations, Nittan’s EV-PYS Optical Detector with built-in sounder was selected for convenience, due to the reduced cost and time required compared to installing separate detectors and sounders, as well as the combined detector/sounder providing a more aesthetically pleasing solution.

Compliant visual alarm

In the open areas, such as the cinema room, games room, common room and the communal garden terrace, Nittan EV-HIOP-SB High Output Sounder Beacon VADs were installed. These devices provide high volume sound, EN 54-23 compliant visual alarm and are waterproofed to IP65, making them suitable for the outdoor areas. One of the most important devices in any fire alarm system is Manual Call Points, which are strategically located in the Dagfa House development at points of evacuation.

Nittan EV-MCP2-SCI Call Point with built in short circuit isolators were chosen to ensure the loops were adequately protected, so the system remains compliant even under short circuit fault conditions. Each Call Point was also fitted with a hinged front cover for compliance with BS-5839-1: 2017, the code of practice for designing, installing, commissioning, and maintaining fire detection and alarm systems. Nittan fire detection systems are a popular choice for student accommodation, with many applications around the UK.

Even with Firefighters Retiring Earlier, Pension Costs Remain Manageable
Even with Firefighters Retiring Earlier, Pension Costs Remain Manageable

Because the physical challenges take a toll, firefighters tend to retire at earlier ages than other occupations. There is also a greater likelihood of workplace disability. Firefighter pension plans are often more generous to offset a lack of Social Security eligibility for some public safety employees. Also, more years of retirement translate into an overall increase in medical care costs for fire service retirees. Therefore, pension benefits for public safety workers are more expensive than those for other government employees, according to an analysis by the Center for State and Local Government Excellence (SLGE). Even so, retirement costs for firefighters and police officers represent only a small percentage of total expenditures for city, county and school district jurisdictions – around 2%. Even if you focus on jurisdictions in which public safety costs are most significant—the city and county levels – the burden is still small, averaging only 4.9% of aggregate spending for cities and 1.9% for counties. Pension Changes Could Impact Firefighter Recruitment Pension benefit generosity is about 25% greater for police and fire employees Any changes in retirement or medical care plans could negatively impact efforts to recruit enough firefighters, which are already a challenge. For example, shifting the retirement age would reduce total employee compensation, which could negatively affect retention. A wage increase to offset the change would maintain total compensation at previous levels. In 2016, the costs of pension benefits earned for police and fire personnel made up 15% of the payroll, compared with only 8% for non-public safety local employees. Annual retiree health care benefits made up 6% of payroll, compared to 4% for other employees. Analyzing Retirement Benefits Earlier retirement ages translate into longer retirement periods for these workers, which impact higher pension costs. Public safety employees are eligible for their benefits at younger ages than other groups, even though the average expected lifespans at retirement are similar. Pension benefit generosity is about 25% greater for police and fire employees, a difference that offsets the lack of Social Security coverage for some public safety employees. Any changes in retirement or medical care plans could negatively impact efforts to recruit enough firefighters, which are already a challenge “Local governments across the country are continually analyzing the retirement benefits provided to the public safety workforce, along with associated costs,” says Joshua Franzel, PhD., President and CEO of SLGE. “This research provides government leaders and policymakers with a national snapshot so they can make informed decisions.” Outdated Assumptions? Some evidence suggests that assumptions about earlier retirement ages for police and firefighters may be outdated. Despite the physical demands of the jobs, some local governments have sought to retain experienced employees using a Deferred Retirement Option Plan (DROP), which allows employees to claim pensions while continuing to work. Higher DROP participation rates – with some public safety employees working five years longer – suggest that employees may be able to stay on the job until later ages. Also, the U.S. Army (whose jobs can also be physically demanding) has raised its mandatory retirement age for active duty soldiers from 55 to 62.  emphasizing employee health and fitness Use of technology can help to ease the physical burdens of public safety jobs, and an emphasis on employee health and fitness can also improve the picture. The analysis was conducted by CPR researchers Jean-Pierre Aubry, Associate Director of State and Local Research; and Kevin Wandrei, Research Associate. The research assesses the size of public safety retiree benefit costs using public safety employee data from the Public Plans Database, the U.S. Census Bureau, and government actuarial valuations.

Volunteer Departments Face Grim Finances As Pandemic Eliminates Fundraisers
Volunteer Departments Face Grim Finances As Pandemic Eliminates Fundraisers

Among volunteer fire departments, spring is a prime season for fundraising. But not in 2020. Concerns about the spread of the novel coronavirus have ruled out the possibility of large public gatherings. A consequence of the coronavirus shutdown is cancellation of hundreds of volunteer fire department fundraisers across the United States – from fish fries to bingo to hog roasts to chicken barbecues. No more carnivals or spaghetti suppers or gun raffles. And departments are losing thousands of dollars. The resulting financial burden is a momentous and imminent threat to the operation of volunteer fire departments, some of which do not receive any government funding. With two months or more of fundraising lost forever, the economic stability of volunteer fire departments is called into doubt. Underlying the problem is another sobering reality: Fires don’t stop just because of coronavirus. However, overall calls are down for some departments, which provides some level of relief.   Virtual And Online Fundraising Hope springs eternal that some variation of fundraising can resume if things get back to “normal” in June or later this summer. If not, in a worst-case scenario if stay-at-home orders remain in place for several more months, some volunteer departments could be forced to shut down. Raising money may not get any easier for months to come. Underlying the problem is a sobering reality: Fires don’t stop just because of coronavirus Some departments have experimented with virtual and online fundraisers, with mixed results, although the efforts are unlikely to replace the lost revenue from events canceled because of social distancing and stay-at-home orders. Examples include Facebook Live raffles and various types of electronic donation collections. Some volunteer departments operate social halls and rent them out for a variety of public events. With those events cancelled, too, another possible source of revenue is eliminated, at least for the near term. Volunteer Fire Department Costs Some departments have experimented with virtual and online fundraisers, with mixed results Department costs are unrelenting – and varied. They have to pay basic utilities such as electricity, heat and internet, as well as buy fuel for their trucks. Some have loan payments on fire trucks and other equipment, and various maintenance costs, not to mention insurance on equipment and supplemental insurance for firefighters. Just as many households are reeling from the economic impact of the pandemic, many fire departments also find themselves suddenly thrust into uncertain times facing a downwardly spiraling budget and little way to make up the deficit. Rather than living paycheck-to-paycheck, they are accustomed to working fundraiser-to-fundraiser. In general, donations dwindle in a down economy. Some departments are having to slash up to half their spending, addressing the dilemma with a brutal reevaluation of their department’s finances. They are separating “needs” that can’t be ignored from “wants” that can be delayed or eliminated.  For example, purchase of replacement equipment may need to be delayed for a period of time. Navigating Uncharted Waters Volunteer fire departments were already facing challenges such as recruitment and retention declines, and a dearth of funds aggravates the existing challenges. State and municipal governments provide funding to volunteer fire departments in some locales, but can those funds be counted on as governments face their own shortfalls? Tax support and municipal funds may not be a sure thing in the era of COVID-19. The fact is, we are all in uncharted territory.
