Grade 2 and Grade 3 intruder alarm systems that protect your building when no one is there — monitored 24/7 via independently approved Alarm Receiving Centres.
Schools house expensive IT equipment, musical instruments, catering equipment and sensitive personal data. Local authority buildings contain cash, controlled documents and assets that attract opportunistic theft. NHS premises hold medication, medical equipment and confidential patient records. All of these buildings are empty for long periods — evenings, weekends, school holidays — making them attractive targets.
An intruder alarm system is only as good as its installation grade, its monitoring and its response. We design insurance-grade systems that actually deter, detect and respond — not just make a noise that nobody acts on.
From system design and installation to ARC monitoring and ongoing maintenance, we deliver intruder alarm solutions that satisfy your insurer, protect your assets and give your facilities team confidence.
Grade 2 and Grade 3 intruder alarm systems designed to BS 8243, professionally designed and installed to BS 8243. We design detection coverage around your specific building — using passive infrared (PIR), dual-technology, microwave and perimeter beam detectors as the environment demands — to achieve reliable detection without excessive false alarms.
Connection to our independently approved Alarm Receiving Centre partner for 24/7 monitoring of your alarm system. When a genuine alarm signal is received, the ARC contacts your keyholders and, where agreed, notifies the police — within seconds of activation, any time of day or night.
Dual-path signalling uses two independent communication routes — typically broadband and cellular — to transmit alarm signals to the ARC. If an intruder cuts your phone line or broadband connection, the cellular path ensures the alarm signal still gets through.
Modern alarm panels with app-based management allow authorised staff to set, unset and check the status of the alarm system from their smartphone — essential for schools and public buildings with multiple keyholders and frequent out-of-hours access requirements.
Annual planned preventative maintenance visits keep your system in peak condition and produce the compliance certificates your insurer requires. We test every detector, siren, battery and communication path — and provide a full written report after every visit.
Every Fyrfly intruder alarm installation meets the standards your insurer requires and the quality your organisation deserves.
Your intruder alarm is the last line of defence when your building is empty. We design systems that detect reliably, signal with certainty and respond without delay.
False alarms erode police response and exhaust keyholders. We use dual-technology detectors, careful placement and confirmation logic to achieve the lowest possible false alarm rates — without compromising on genuine threat detection.
Schools with evening lettings, NHS buildings with 24-hour access and council buildings with mixed tenancies all need alarm systems that can part-set specific zones. We design zoning around your operational patterns, not the other way around.
An alarm that triggers your CCTV to record and your monitoring centre to pull up live images is worth significantly more than one that just makes a noise. We design intruder alarms as part of an integrated security ecosystem from the start.
The zoning, grade and monitoring requirements for a school differ significantly from a council office or NHS building. We design to the specific needs of your environment.
Flexible zoning for out-of-hours lettings, insurance-grade detection and ARC monitoring tailored to the demands of school sites.
Grade 2 and Grade 3 installations for public buildings, depots and offices — meeting insurer requirements and protecting public assets.
