Fire Safety - Maintenance of Protection Systems

In general all commercial/public buildings in the UK will incorporate some form of active fire protection system.

Having been installed and appropriately commissioned, these systems are designed to operate in a desired manner, ensuring both the building and its occupants are protected.  Unfortunately as with all electrical and mechanical systems, failure is possible. 

To reduce the likelihood of failure, all fire protection systems must be subject to regular checks, testing and maintenance.  These actions ensure the system is working correctly and any items that are subject to failure, through ‘wear and tear’ etc can be identified and appropriate remedial action taken.

The reason for reducing the likelihood of failure, is the matter of consequence.  It is likely that most (if not all) of the fire safety systems installed in the UK have been installed as life safety installations, i.e. they protect life.  Therefore, failure of such a system could ultimately lead to injuries or even death.

It is not the intention of this bulletin to detail every code requirement for system checks, but to provide an overview of the most common requirements in typical buildings.

System Checks

Many fire safety installations require daily, weekly and monthly checks.  The general rule is that the more frequent the check, the less involved or intrusive it is.  For example, the daily check on a fire alarm system involves a visual check on the fire alarm panel(s), to ensure correct operation, i.e. no faults are indicated.  Similarly, with emergency lighting systems, does each unit appear to be working correctly, do any units appear damaged. 

System Tests

With a lower frequency, comes a more intrusive, involved form of testing.  These tests are typically on a weekly / monthly basis and are normally performed by in-house staff / facilities management.  The most common basic test of a system we should all be aware of, is the weekly fire alarm test.  This test is performed to ensure that the manual call points are sending a signal to the fire alarm panel.  This test also ensures that the sounders are working correctly and allows the occupants an opportunity to report any audibility issues as well as becoming familiar with the sound of the alarm. 

A less common system, but equally important (if installed) is a sprinkler system.  This will be subjected to weekly tests, which ensures the basic operation of the system, pumps and water supply.  This will often be an insurance requirement as failure to meet the insurer’s maintenance checks may invalidate the insurance policy.

Servicing & Maintenance

With most installations, there will be a periodic requirement to service a system, similar to a car.  This tends to be a more involved process and may require replacement of parts.  Most standards require this to be carried out by an appropriately trained engineer accredited with the appropriate qualifications.  Servicing should pick up any technical system faults and can also be used for planned maintenance, when a component is identified as nearing the end of its useable life, servicing will take appropriate action to ensure its replacement prior to failure.

Servicing of systems tends to be less frequent, for example, monthly quarterly or even annually.  This can depend on the system as well as other factors such as the risk group of the building and the size of the installation.


The fire safety protection systems installed in buildings are, in the norm, primarily there to protect life.  We must be mindful of the importance of these systems when we test and maintain them as their failure could have catastrophic results.

  • Fire Engineering Design and Risk Assessment - Firefighting & External Water Supplies - Part 33

    In LWF’s Fire Engineering blog series for Architects and others in the building design business, we have been looking at firefighting and the associated provisions that need to be made for the Fire Service. In part 32, we looked at the standards for wet and dry mains given in Approved Document B and BS 9999. In part 33, we consider dry mains in more detail.A dry rising main is comprised of pipework installed vertically...


  • Fire Safety for Healthcare Premises - Fire Safety Policies - Part 67

    In LWF’s blog series for healthcare professionals, the aim is to give information on best practice of fire safety in hospitals and other healthcare premises. In part 66, we were discussing how fire safety policies should be formed and finished by noting that consultation with all types and levels of staff in a healthcare setting is necessary to ensure a considered and cohesive fire safety policy. In part 67, LWF will continue looking at fire...


  • Facilities Management & Fire Safety - Insurers & Property Protection - Part 14

    LWF’s blog series for those who work in Facilities Management, or who have an interest in or responsibility for fire safety has been looking at the impact of the insurer on property protection from fire. In part 13, while acknowledging there are significant areas of overlap between life safety and property protection measures, we began to look at those areas where measures taken to protect property from fire would not benefit life safety aims, and...


  • Fire Engineering Design and Risk Assessment - Firefighting & Internal Water Supplies - Part 32

    In LWF’s Fire Engineering blog series for Architects and others involved in the building design business, we have been looking at fire safety engineering and, most recently, firefighting. In part 31, we looked at the recommendations made regarding water capacity for any open water used for firefighting purposes and discussed relaying water to the place of fire origin. In part 32, we look at internal water supplies designed for the purpose of firefighting.Fire mains...


  • Fire Safety for Healthcare Premises - Fire Safety Policies - Part 66

    In LWF’s blog series for healthcare professionals, our aim is to give information on best practice of fire safety in hospitals and other healthcare premises. In part 65, LWF considered some of the many important elements when considering general fire safety in a healthcare building, including the provision of alternative escape routes and the potentially unpredictable nature of human behaviour in a fire situation. In part 66, we look at fire safety policies.Clearly-defined fire...
