Modern buildings and safety legislation require industry to deliver new modes of protection as the uses of buildings become more complicated; to ensure performance and deliver clearer compliance; and to do so faster and more efficiently, with more defined costs and minimum disturbance to ‘business as usual’.

quick and efficient installation

In the current environment the pressures on end users to maintain the very best fire system protection for their occupants and installers to ensure they safely, quickly, and efficiently install compliant, high-performance systems have become much higher.

The installation needs to be completed by spending as little time on site as possible; while respecting social distancing and H&S regulations; disturbing occupants' lives or businesses as little as possible, and all the while guaranteeing costs and timeframes.

commissioning and maintenance

The capabilities of the modern fire system are far beyond what could be offered even 20 years ago

While fire technology is always developing and the capabilities of the modern fire system are far beyond what could be offered even 20 years ago, the basic concept of individual devices connected by wired loops to fire panels has not changed in decades.

Projects generally follow the same process of risk assessment, design, and quote. Then, if won, they move on to installation commissioning, and maintenance. Professionals will be competing with largely the same technology, offering systems that are largely identical except for a few differences in cause and effect.

Plan and complete installation

Even once the tendering process is over, installing a fire system can take months to plan and complete. Depending on the use of the building, there are often things users need to work around and, even when work gets underway, there can be unexpected issues that delay the schedule and increase the cost.

These might range from changes to the building that weren’t included in the plans, to asbestos and external factors, such as the availability of other contractors and trades.

wired fire system

With a wired fire system there are many uncertainties that users have learned to live with, which means the fire installer, project manager, or the end user does not have full oversight of the situation. This makes it difficult to allocate staff resources effectively, particularly when you need different skills at different times and creates a much greater logistical challenge. 

All of this generates uncertainty for fire professionals, end users, and often the occupants of a building, as well as adding to costs.

Wireless fire detection and alarm products

Wireless fire detection and alarm products are widely accepted with the best commercial systems and devices

Wireless fire detection and alarm products hold an answer to many of these challenges.

The technology is mature and widely accepted with the best commercial systems and devices, such as those from Argus, having the same sensing and performance approvals as the best-wired systems, and a specific performance approval (EN54-25) for the wireless infrastructure.

Wireless devices

Wireless devices have traditionally been used in sites where wires cannot go, such as historic buildings, because of their ability to cover large areas and the fact that they can be fitted with minimal disruption to the building’s fabric.

They are becoming mainstream, installed in all manner of sites from industrial sites to schools.

Cost-effective alternative

In fact, over the past decade, rapid advances in technology and manufacturing have made wireless a viable and cost-effective alternative for many fire systems, eliminating the need for cable and all of the problems it can bring.

For example, a recent Argus project in the Middle East saw a school design and installation take 4 days from the start to sign-off.  Contrast that to a sister school that had taken 8 months with a traditional wired system, with all of the cost, disturbance, and fire watch required over the project.

Hybrid configuration

Some systems function either in fully wireless modes or in a hybrid configuration with wireless devices mixed

Some systems such as Argus’s can offer the best of both worlds, functioning either in fully wireless modes or in a hybrid configuration with wireless devices mixed in any combination on wired loops.

There are no surprises with a wireless system, the exact devices required are defined in the initial survey, and the system can be pre-programmed quickly and easily off-site and installed by less skilled workers, in less time.

Eliminated costs and time savings

Disturbance to tenant businesses and the need for fire watches are all but eliminated and costs and timescales are guaranteed, plus the time savings mean that many more projects can be completed.

The result is that the vast majority of installation firms have at least installed wireless ‘add-on’ systems and a significant number are wrapping their businesses around the wireless model.

List of suppliers

The list of suppliers and range of available wireless fire alarm and detection devices is comprehensive, but it is worth working with a leading commercial wireless company.

It is also worth choosing a supplier that is a specialist in wireless fire devices, not simply wireless devices. The definition is subtle but profound when performance considerations come into play.

Battery technology 

Advances in battery technology and LED lighting mean wireless systems can run for many years without a battery change

A serious commercial wireless manufacturer will have the best chamber designs with dual angle detection, multiple sensing technologies, all the relevant input, and output devices, and often, like Argus high-performance EN54-23 devices, specialist control modules such as wireless door holders, and even very specialist devices such as Intrinsically Safe.

Advances in battery technology and LED lighting mean wireless systems can run for many years without a battery change, a period that’s likely to extend further in the future.

No-compromise approach

Battery choice, lifetime, and the cost of batteries become key differentiators in wireless systems, some manufacturers use ‘off-the-shelf batteries’ that can be bought in a supermarket, others specialist batteries, and so more expensive, potentially locking in maintenance suppliers and costs.

Standard commercial batteries will also see performance, environmental, and cost improvements as they are used very widely. In short, the best wireless fire detection technology offers a no-compromise approach to protection with several unique benefits that make it ideal for all types of installation, regardless of the age, usage, or construction of the building in question.

Assurance and adaptability

All wireless fire systems begin with a pre-installation survey, taking a detailed look at the building, identifying any potential issues to be overcome, pinpointing the exact location of each wireless device, and working out an exact schedule for installation and testing.

It will ensure that the completed system will perform as specified, which is a guarantee that wired systems, with their susceptibility to loop faults, can often struggle to maintain, and will also certify the cost of the project, which means no hidden surprises that can change installation projects and even system design and performance.

Wireless communication network

Standard addressable or conventional panels connected via the fire loop to wireless translators

Wireless products are common in every other industry and wireless fire devices are seen by many as equal to, or even superior to, old-fashioned wired versions.

The basic topology of the system remains the same, using standard addressable or conventional panels connected via the fire loop to wireless translators. These build up the wireless communication network, on which the input and output devices sit.

Remote systems

Systems can grow from very small to very large, easily and reliably. The extent of these high-performance systems is limited only by installation standards or the number of devices that a fire panel can control.

Wireless and hybrid systems can be scrutinized and controlled remotely in the same way as any wired installation, offering a round-the-clock view of system status.

Communication system

In terms of monitoring and control, while some wireless systems limit the communication with the panel, the best, such as Argus’s, deliver rich data over the loop and are indistinguishable from a wired system in configuration, performance, and control terms.

This means that all cause and effect, such as false alarm management and monitoring, are readily available.

Wireless is the Future of Fire Systems

With less time needed to install or update each system, it’s possible to deliver improvements quickly and efficiently

Industry bodies such as the UK’s FIA (Best Practice Guide to Fire Safety) have acknowledged the value of wireless technology to help meet changing standards in the fire industry and it can also help to address some of the other challenges we are facing.

With less time needed to install or update each system, it’s possible to deliver improvements quickly and efficiently, with short lead-in times and less manpower.

Wireless adoption

In terms of outlay, because there are no nasty surprises to be found during the installation of wiring loops, installers, and specifiers of wireless can guarantee installation costs, and radically reduce commissioning costs, making their businesses stronger, offering certainty to the end client, and allowing jobs to be scheduled more reliably.

Unlike some new technologies, always waiting for widespread adoption and acceptance in the industry, wireless fire systems are already mainstream and have been for many years. As wireless permeates most of the modern building infrastructure, it will surely become the standard choice.
