Fire Alarm Zone Plans — Design & Installation
A current, legible, and accurately positioned fire alarm zone plan at the main control panel is a BS 5839-1 requirement — not optional. We design, produce, and install fire alarm zone plans for commercial premises across Burnley, Lancashire, and the wider North West.
What Fire Alarm Zone Plans Are and Why They Matter
A fire alarm zone plan (also referred to as a graphic zone chart or mimic chart) is a diagrammatic representation of the building's fire alarm zones — showing which areas of the building fall within each zone, where the detectors and call points are located, and how zones relate to the building's floor layout.
BS 5839-1 Section 23 requires that a zone plan is permanently displayed at, or immediately adjacent to, the main fire alarm control panel. The purpose is to enable the first point of attendance — whether that is on-site staff, security personnel, or the fire and rescue service — to quickly identify the location of an activation and respond appropriately.
The zone plan must accurately reflect the current configuration of the system. An out-of-date zone plan — showing zones, floors, or areas that no longer match the actual system — is not only useless in a fire, it may also lead responders to the wrong area.
Zone Plan Requirements Under BS 5839-1
- Must be displayed at or adjacent to the main control panel
- Must clearly show zone boundaries and their relationship to the building layout
- Must identify all zones by their panel zone number or label
- Must be kept up to date following any changes to the system or building
- Should be of a size and legibility that allows clear reading in an emergency
- Should be laminated or protected from deterioration
When Zone Plans Are Required
New Fire Alarm Installation
Every new fire alarm installation requires a zone plan. We produce the zone plan as part of the commissioning process, reflecting the final as-installed configuration of the system.
System Upgrade or Alteration
When zones are added, removed, or reconfigured, the existing zone plan becomes out of date and must be updated. We produce updated plans following any system alteration.
Building Alterations
Where the building layout changes — new partitions, altered floor layouts, extended areas — the zone plan must be reviewed and updated if the changes affect how zones are represented.
System Takeovers
When taking over an existing system, we audit the zone plan as part of the initial inspection. Plans that are absent, illegible, or inaccurate are identified and replacement is recommended.
Lost or Damaged Plans
Zone plans deteriorate over time, particularly in industrial environments or near equipment that generates heat or fumes. Where the existing plan is no longer legible or has been lost, a replacement must be produced.
Compliance Gaps
During maintenance visits or fire safety audits, the absence of an adequate zone plan is commonly identified as a compliance gap. We can produce a new plan quickly to resolve this.
How We Design and Produce Zone Plans
- Review of existing system documentation, device schedules, and drawings where available
- Site survey to verify zone coverage, device locations, and floor layout
- Design of the zone plan drawing — floor-based layout showing zone boundaries and locations
- Review by client where required
- Print and laminate — durable, protected zone plan ready for installation
- Installation adjacent to the fire alarm control panel
- Record of zone plan in system logbook
In cases where no existing documentation is available, we carry out a full site survey and build the zone plan from scratch based on the as-installed system. This is common on system takeovers and for older systems where original documentation has been lost.
Zone plans for multi-floor buildings are typically produced as separate floor plans, compiled into a set and displayed in a clear sleeve or frame at the panel.
What a Good Zone Plan Contains
- Floor plan outline — accurate representation of the building footprint and layout
- Zone boundaries — clearly delineated areas corresponding to each panel zone
- Zone numbers or labels — matching the zone designations on the fire alarm panel
- Device symbols — optional but useful, indicating the type and approximate location of devices
- North arrow and floor level indicator
- Company name and date of production
A zone plan does not need to be a detailed architectural drawing. What matters is that it is clear, legible, and accurately represents the current zone configuration of the system. A simple, well-produced plan that can be read quickly in a stressful situation is more useful than a complex drawing that is difficult to interpret.

Zone Plans — Frequently Asked Questions
Is a zone plan legally required?
BS 5839-1 requires that a zone plan is displayed at the main control panel. While BS 5839-1 is a British Standard rather than a statutory requirement in itself, the Regulatory Reform (Fire Safety) Order 2005 requires that fire detection and alarm systems are maintained in efficient working order. An absent or inaccurate zone plan is commonly identified during fire safety audits and can be cited as a compliance failure.
Our zone plan is out of date — can you update it?
Yes. Bring us the current zone plan and details of what has changed, and we can produce an updated version. Alternatively, if you are unsure what has changed, we can carry out a survey to verify the current system configuration and produce a new plan from the survey findings.
Do you produce zone plans for multi-floor buildings?
Yes. Multi-floor buildings typically require a separate plan for each floor, compiled as a set and displayed in a sleeve or frame at the panel. We produce multi-floor zone plan sets as standard.
Can you produce a zone plan if there are no existing drawings?
Yes. Where no existing drawings or documentation are available, we carry out a site survey and produce the zone plan from scratch based on what is installed. This is common on older systems and system takeovers.
