Premises Information and Secure Information Boxes
When the fire and rescue service arrives at a building, the first minutes are shaped by what they know. Premises information — floor plans, key building details, and in some buildings a dedicated secure information box near the entrance — exists to give responders that knowledge quickly. It sits close to the world of the fire alarm engineer without being their responsibility, and understanding it helps an engineer keep the fire alarm's own information useful and know what to flag. This guide covers what the information is for and where the engineer's part begins and ends.
The central point is that premises information supports the fire service's response, and the engineer's job is to keep the fire alarm's contribution to it accurate and to flag obvious gaps.
Who this is for
This is for competent fire alarm and security engineers who work in buildings where premises information or a secure information box is provided. The experience level assumed is competent engineer. Use it to understand the purpose and the boundaries of your role; providing and maintaining the information itself is a management responsibility under the applicable regulations and the fire risk assessment. The fire alarm's own information follows BS 5839-1.
What premises information is for
A secure information box is a secured box, usually near the main entrance or the fire alarm panel, holding information the fire and rescue service needs on arrival — floor plans and key building details, kept current and accessible to responders. Its purpose is to speed and inform the response when it matters most. In certain higher-risk residential buildings the provision of such a box is a legal requirement under specific fire safety regulations; in other premises, equivalent information may be provided in other ways. What is required for a given building comes from the applicable regulations and the fire risk assessment, not from a single universal rule.
How it relates to the fire alarm
The information supports the fire service's response and frequently sits alongside the fire alarm panel and any zone plan or mimic, so an engineer will regularly encounter it. Providing and maintaining the box is a management responsibility rather than the engineer's, but understanding its purpose means the engineer neither obstructs it nor misrepresents it, and appreciates how it fits with the fire alarm's own information. The zone plan and panel indications complement the premises information, helping responders locate an alarm, and are maintained within BS 5839-1. The two forms of information work best when both are accurate and consistent.
Whose responsibility it is
It is worth being clear about ownership. Providing, populating and maintaining premises information — including any required secure information box — is the responsibility of the responsible person or duty holder for the building, informed by the applicable regulations and the fire risk assessment. It is not the fire alarm engineer's duty. The engineer's part is narrower and specific: keep the fire alarm's own information, such as the zone plan, accurate, and flag if the wider premises information is clearly missing, inaccessible or out of date. Duties for the box itself sit firmly with the responsible person.
The engineer's part on service
On service, focus on what is within the fire alarm remit while staying alert to the wider picture. Confirm the zone plan and panel information are accurate and match the building, and note — for the responsible person — if a required information box appears missing, inaccessible or badly out of date. From field experience, an out-of-date zone plan that no longer matches an altered building is squarely a fire alarm finding, whereas a missing or neglected box is a management matter to flag rather than fix. Record what you find, and direct box-related issues to the responsible person clearly.
Common points to check
Recurring issues include a zone plan that no longer matches the building, and, as items to flag, a required information box that is missing, inaccessible or out of date. Confirming the fire alarm's own information is accurate and flagging wider gaps is the essential check.
When not to rely on this alone
When not to use this article: do not treat it as a specification for what premises information a building must provide. That comes from the applicable regulations and the fire risk assessment, applied by the responsible person and competent professionals.
Relevant standards
The fire alarm's own information follows BS 5839-1, a code of practice; premises information and secure information boxes are driven by the applicable fire safety regulations and the fire risk assessment. The general legal duty for fire precautions in most non-domestic premises sits under the Regulatory Reform (Fire Safety) Order 2005, with additional duties for certain residential buildings under the Fire Safety (England) Regulations 2022. Separate the legal duty from the recommended methods, and always work to current editions.
