Fire alarm panel location requirements
Where the fire alarm control panel should be sited, why location is critical for effective response, what BS 5839-1 requires, and common mistakes to avoid.
The location of the fire alarm control panel is more important than it might appear. The panel is the first point of reference when an alarm activates — it tells the responding person where the fire is and gives the fire service the information they need on arrival. A panel sited in an inaccessible location, a locked room, or an area at risk of early fire involvement fails in its primary purpose of directing an effective response.
Where Should the Control Panel Be Located?
BS 5839-1 sets out several requirements for control panel location. The overarching principle is that the panel should be in a position where it can be seen and attended to promptly when an alarm activates, and where the fire service can find it quickly on arrival at the building.
| Requirement | Detail |
|---|---|
| Near the main entrance | The panel should normally be sited at or near the main entrance used by the fire service — so that arriving crews can immediately access the panel without searching the building |
| Accessible at all times | The panel must be accessible whenever the building is occupied, and ideally at all times. A panel in a locked office or behind a security door that requires a code creates a delay that may be critical |
| Away from fire risk | The panel should not be sited in an area at elevated risk of fire — a kitchen, boiler room, or electrical intake room. Early involvement of the panel location in a fire could disable the system before full evacuation |
| Away from flooding risk | Basement locations or areas below water pipes present a flood risk that could disable the panel. Where a basement location is unavoidable, the panel must be suitably protected |
| Protected from tampering | The panel should not be in a public area where unauthorised persons could interfere with it — but the level of protection must not prevent authorised access in an emergency |
| Suitable environment | The panel should be in a location with stable temperature and humidity — extremes of temperature or moisture can affect panel electronics and battery performance |
Fire service access
Why the Fire Service Needs to Find the Panel Immediately
When the fire service arrives at a building in alarm, their priority is to assess the situation as quickly as possible. The control panel — showing which zone is in alarm and, on addressable systems, which specific device — tells them where to direct their initial attack and which parts of the building to prioritise for search and rescue.
In a building where the panel is hidden in a back office, accessible only through a locked door, or in a basement the attending crew has never visited, that critical information is delayed. BS 5839-1 therefore requires that the panel is in a location the fire service can reach immediately on entry — typically the main reception area or the entrance lobby of the building.
The “Firefighter’s Switch” Principle
The same principle that requires firefighter’s switches for high-voltage signs and luminous tube installations applies to fire alarm panels — the responding authority must be able to access controls quickly and without hindrance. In multi-tenanted buildings or those with security access systems, a key safe or agreed access point for the fire service should be considered alongside correct panel location. The fire service cannot use information on a panel they cannot reach.
Repeater panels
When a Repeater Panel Is Needed
In some buildings, the ideal location for the main control panel — close to the main entrance — is not where operational staff are based. A hotel reception may be close to the entrance, but the security office where staff are always present may be elsewhere. In these situations, BS 5839-1 permits the use of a repeater panel — a secondary display panel that mirrors the zone indication of the main panel and allows the alarm to be silenced and reset from a second location.
Repeater panels are also used in large buildings where a single panel at the entrance cannot practically show all zones in sufficient detail. The main panel stays at the entrance for fire service access; repeater panels are positioned at staffed locations for operational management of the system.
Common questions
Frequently Asked Questions
Not ideally — plant rooms are often at elevated fire risk and may not be accessible to the fire service without keys or codes. BS 5839-1 recommends against siting the panel in areas of elevated fire risk, and a plant room or service cupboard is likely to fail the accessibility test as well. Where no better option exists, the panel should be protected from the fire risk in the plant room, and the fire service should be made aware of the location via a notice at the main entrance.
In buildings without a permanently staffed entrance, the panel should still be positioned at the main entrance used by the fire service — typically the front door or the entrance most visible from the street. A notice on the exterior of the building indicating the location of the fire alarm panel is recommended by BS 5839-1. In unmanned premises, ARC monitoring provides the human response element that the unattended panel cannot.
The panel itself typically has a lockable door covering the controls to prevent unauthorised access, while the zone display remains visible through a window or LED indicators on the door. This arrangement satisfies both the need to protect the controls from interference and the need for the zone indication to be readable without unlocking the panel. Keys should be held by authorised personnel and available at all times — not in a key cabinet that requires a code to open.
