Fire Detection System Maintenance

In commercial and residential properties alike, fire detection and suppression systems form the backbone of a robust fire safety strategy.

These systems are designed not just to alert occupants to danger but also to actively control or suppress fires in their early stages. However, their effectiveness hinges on regular, professional maintenance.

Here we explore the vital role of fire detection system maintenance, the regulatory framework that governs it, and how FDS Maintenance ensures systems remain compliant, reliable, and responsive when it matters most.

Why Fire Detection & Suppression Maintenance Is Critical

Compliance with Fire Safety Legislation

The Regulatory Reform (Fire Safety) Order 2005 requires that fire detection and suppression systems be “subject to a suitable system of maintenance” to ensure they remain in efficient working order. Failing to comply with these regulations can result in prosecution, invalidated insurance, or, in worst-case scenarios, loss of life.

Additionally, the British Standards relevant to these systems include:

  • BS 5839-1: For the design, installation, commissioning and maintenance of fire detection and alarm systems
  • BS EN 15004: For gaseous fire suppression systems
  • BS 5306-3: For portable fire extinguishers

Operational Continuity

For businesses, especially in critical environments like data centres, hospitals, and manufacturing facilities, even a brief system failure could lead to catastrophic damage. Maintenance prevents these lapses and helps protect valuable assets.

Key Components That Require Maintenance

Fire Detection Systems

Fire detection systems encompass a variety of components, including smoke detectors, heat detectors, manual call points, and alarm sounders. Maintenance tasks for these systems typically include:

  • Testing all detectors for functionality
  • Cleaning detectors to avoid false alarms
  • Verifying battery condition and replacing as necessary
  • Checking the control panel displays, fuses, and event logs
  • Ensuring compliance with BS 5839-1 requirements

Fire Suppression Systems

Suppression systems differ in form and function depending on the environment. They include:

  • Sprinkler Systems: Require pressure checks, flow tests, and inspection for corrosion or obstructions.
  • Gaseous Systems (e.g. FM200, CO2): Periodic cylinder weighing, discharge tests, and tightness checks are critical.
  • Foam Systems: Must be tested for consistency, concentration, and delivery mechanisms.

A good maintenance provider will ensure that all components meet British Standard guidelines and will maintain detailed servicing records.

Fire Extinguishers

While portable, extinguishers are a vital first-response tool and should be serviced annually:

  • Check the pressure gauge and tamper seals
  • Inspect hoses, nozzles, and cylinders for damage.
  • Confirm weight and refill or replace if needed.
  • Verify that the location and signage are compliant with health and safety regulations.

How Often Should Maintenance Occur?

Fire detection and suppression systems must be serviced according to the following general schedules, though individual needs may vary:

  • Fire Alarms: Every 6 months (as per BS 5839)
  • Suppression Systems: Quarterly or biannually, depending on system type and environment
  • Extinguishers: Annually, with extended service every 5 years (foam/water) or 10 years (CO2)
