For many business owners and facilities managers, the fire alarm system is something that sits in the background: a series of red boxes and white discs that you hope you never actually have to think about. But fire safety isn't just a "fit and forget" exercise. It is a legal obligation that evolves as standards change and buildings age.
The most significant shift in recent years is the introduction of BS 5839-1:2025. This updated code of practice for non-domestic premises has raised the bar for what "compliance" actually looks like. If your system was installed five or ten years ago, there’s a high chance it’s falling behind current requirements.
Being non-compliant doesn't just mean a slap on the wrist from a fire officer; it can invalidate your insurance and, more importantly, put lives at risk.
Here are 10 common reasons why your business fire alarm system might not be compliant today: and, more importantly, how you can fix it.
1. You’re Still Following the 2017 Standards
The fire safety landscape changed significantly with the arrival of BS 5839-1:2025. This updated standard replaced the 2017 version and introduced stricter rules around everything from detector placement to manual call points. If your last major system review was based on the old 2017 guidance, you may be missing critical updates, especially regarding "sleeping risks" (like hotels or care homes) where smoke detectors are now the absolute preference over heat detectors.
How to fix it: Schedule a professional audit. At JKE Fire & Security, we don’t just "check the boxes"; we look at your system through the lens of the latest 2025 standards to ensure you aren't lagging behind.
2. Your Fire Safety Logbook is Missing or Incomplete
If a Fire Officer walks into your building today and asks for your maintenance records, could you produce them? A missing or poorly maintained logbook is one of the most common reasons for non-compliance. You must record every weekly test, every false alarm, and every professional service visit.
How to fix it: If you don’t have a logbook, get one immediately. If you do have one, ensure your staff are trained to fill it out after every weekly test. Our team at JKE provides clear documentation with every visit to make sure your records are always up to date.
3. There’s No Accurate Zone Plan Next to the Panel
In an emergency, the Fire and Rescue Service needs to know exactly where the fire is. A "Zone Plan" is a diagram of your building showing the different fire zones. BS 5839-1:2025 treats these as mandatory. If your panel says "Zone 4 Fire" but you don't have a map telling the fire brigade where Zone 4 is, your system is non-compliant.
How to fix it: Ensure a clear, framed, and accurate zone plan is mounted right next to your fire alarm control panel. If you’ve extended the building or moved walls, your zone plan needs to be updated.
4. You Used an Uncertified Installer
It might be tempting to ask a general electrician to "add a couple of detectors" during a renovation. However, fire systems are life-safety systems, not general power circuits. Without the specific competency and certification required by British Standards, that work may not be compliant. BS 5839-1:2025 places a much heavier emphasis on the competence of the people working on your system.
How to fix it: Only use specialist fire security firms. JKE Fire & Security installers are professionals who understand the nuances of the British Standards, ensuring every detector is placed exactly where it needs to be.
5. Your Maintenance Intervals are Outside the "5-7 Month Window"
Routine maintenance isn't just a suggestion; it’s a requirement. The new 2025 standard provides a specific window: professional service visits should occur every five to seven months. If you only have one visit a year, or if your "six-monthly" visits are actually eight months apart, you are technically non-compliant.
How to fix it: Sign up for a planned preventative maintenance contract. We manage the schedule for you, so you never have to worry about missing that compliance window.
6. Manual Call Points Lack Transparent Covers
This is a small detail that catches many businesses out. Under the latest guidance, all manual call points (the "break glass" units) must have transparent protective covers. This is designed to reduce accidental activations and false alarms. If your call points are "naked," they are no longer compliant with the modern code of practice.
How to fix it: These covers can usually be retrofitted to your existing call points. It’s a quick, cost-effective fix that instantly improves your compliance status.
7. Redundant Equipment is Still on the Walls
During a system upgrade, it’s common to see old, disconnected detectors or bell boxes left in place while the new ones are installed next to them. Under BS 5839-1:2025, this is no longer allowed. Redundant equipment must be removed, not just disconnected. Leaving it in place can cause confusion for occupants and emergency responders.
How to fix it: During your next service or upgrade, ask your engineer to identify and remove any dead equipment. At JKE, we believe in tidy, professional installations that leave no room for confusion.
8. Building Layout Changes Haven’t Been Reflected
Did you add a new partition wall to create an office? Or did you move the racking in your warehouse? Even small changes to a building’s layout can create "voids" where smoke detection is inadequate. A detector that was perfectly placed three years ago might now be too close to a new wall or blocked by a ventilation duct.
How to fix it: Whenever you make structural changes to your premises, you should have your fire system layout reviewed. Compliance is tied to the current layout of your building, not the layout as it was when the system was first installed.
9. Fault "Masking" or Suppression
In the past, some engineers might have "masked" a troublesome zone or detector to stop a panel from constantly beeping while waiting for a part. The 2025 standard explicitly prohibits this. Fault masking to suppress notifications is now a clear breach of compliance. If your panel has a persistent fault that is being ignored or "hidden," you are at risk.
How to fix it: Fix the root cause, don't just silence the symptom. Our responsive maintenance team focuses on getting your system back to 100% health quickly, so you don't have to rely on workarounds.
10. Your Staff Don't Know How to Use the System
A compliant system isn't just about hardware; it's about the people using it. If your "Responsible Person" doesn't know how to read the panel, silence a false alarm, or conduct the weekly test, the system is functionally failing its purpose. BS 5839 stresses that the user must be trained and actively participate in the system’s upkeep.
How to fix it: We provide basic training for your on-site team as part of our installation and maintenance service. Making sure your staff feel confident at the control panel is one of the easiest ways to improve safety.
