FIA updates guidance on fire alarm zone plans
The Fire Industry Association (FIA) has issued new guidance in line with BS 5839-1:2025, reinforcing the critical role of fire alarm zone plans in safety and compliance. The updated guidance outlines clearer requirements and classifies the absence of a valid zone plan as a major non-conformity.
What’s changed in the latest guidance?
Key updates include:
- Major non-conformity status now applies if a zone plan is missing, outdated, or inaccurate
- Clarified guidance on what a compliant zone plan must contain
- Common issues with existing plans and how to avoid them
- How to inspect and maintain zone plans for continued compliance
Why fire alarm zone plans are essential
Zone plans are a critical part of fire safety management, especially in multi-zone or sleeping accommodation buildings. They help:
- Speed up emergency response — responders and occupants can quickly locate the source of an alarm
- Reduce risk — identifying the affected area fast can minimise harm to people and damage to property
- Improve clarity — particularly in large or complex buildings like hotels, schools or care homes
Who is affected?
The updated guidance is especially relevant for:
- Responsible Persons under the Fire Safety Order
- Fire safety assessors and consultants
- Facilities managers and building owners
Zone plan checklist
To remain compliant, zone plans should be:
- Clearly marked and accurately reflect the building’s fire detection zones
- Positioned near the fire alarm control panel
- Kept up to date — changes in layout or systems must be reflected
