Today's wireless fire alarms take advantage of the of the most up-to-date radio technology on the market to deliver immediate, yet affordable wireless systems, along with minimal disruption towards the building and surroundings.
Today's systems can be completely wire-free or have a combination of both wired and non-wired to provide a hybrid functionality along with an excellent choice of field devices. The Wireless systems are a secure choice protecting a valuable heritage property, extending the size of a pre-existing wired fire alarm in an occupied hotel or supplying temporary fire cover for a constructing site.
In today's commercial market, there exists a tremendous variety of projects, from ultra-modern, Historical old buildings, Temporary Building structures, all can pose a challenge when considering wiring.
Wire-free systems have provided designers with an exceptionally adaptable and non-intrusion strategy for fire alarm design challenges
Many years ago wireless field devices were a lot larger than their wired counterpart. The reason was due to the size of the electronic components available at that time; however, the advancement of the mobile phone technology has assisted the fire alarm manufacturers ability to produce detectors, sounders and manual call points the same size and appearance as wired units.
To achieve the optimum levels of reliability and performance of wireless field devices which have the same capability of the very best wired products, Wireless relies upon some complex technology.
To comply with the most current European Standard (EN54: Part 25 2008) Radio communication the equipment is Bi-directional and take advantage of the approved 868MHz frequency. Due to the introduction of the CPR (Construction Products Regulations) with allows products to carry the CE mark meaning European Conformity, all Wireless Fire Alarm manufacturers in Europe must comply with EN54-25
The wireless network preserves the security and reliability of transmission using a selection of automated system adjustments, including channel hopping, amplitude realignment and drift harmonising.
The improved transmitting and receiving protocol enables the alarm system to deliver totally intelligent site device implementation and allows analogue information, fire and fault data, device addresses and sort codes to be transmitted to the fire alarm control panel.
All installations will contain a challenging aspect of one sort or another, these might vary from a fragile and ornamental ballroom ceiling, contaminated asbestos structure or an out of the way security station with virtually no cable accessibility.
The wire-free option provides a simple solution to most of these installation challenges. The hybrid approach allows the fire alarm system designer to decide the amount and in which locations the fire alarm has to be wired and which areas wireless, allowing the most cost-effective choice and practical solution. In locations where the site’s architecture or building occupation prevents cabling, this scenario can be managed using a completely wireless installation.
When undertaken the right way, any cabled fire alarm installation demands a contractor who is competent and neat, to prevent the installation from being intrusive. In many cases, there will be a requirement for cable containment, the usage of power tools and in most cases an amount of decoration once the works have been completed. In comparison, all that's required whenever installing a radio wireless device is the capability to fit a few screws per device.
Time is money throughout all avenues of life, whether you're managing a luxurious hotel, busy office or a bank, disruption to your day to day operation is costly. Typically, a building having to close or having the installation carried out, outside normal hours can be expensive.
In these situations, wireless systems now give you a simple option, since their low-noise and quick installation generally allows work to keep going throughout the normal routine site activities.
The installation of the units are non-intrusive, consequently, damage to room decoration or the building structure is avoided as well as the mess and redecoration required following the majority of wired installations.
The wireless fire alarm system is not merely an advanced solution to challenging installation issues but also delivers actual business advantages to the installer and consumer. In addition, a swift installation time cuts down on project time and as a result many other associated project costs. Project managing time, site overheads and access equipment hire all could be reduced.
By applying the most up-to-date equipment at a cost-effective cost and all this together with the reduction in installation costs, allows wireless to be a consideration for any project.
