Fire Alarm Maintenance

The Importance of Fire Alarm Servicing and Maintenance

Fire Alarm maintenance is critical to fire safety; it is written into the statutory law in the UK. We know how important it is to keep your staff, assets, and premises safe from fire outbreaks for any business. Maintaining your fire alarm system is paramount and ensures it is fit for purpose should a fire occur.

Why You Need Fire Alarm Maintenance

Current UK fire alarm regulations state that all business premises must have ‘an appropriate fire detection system’. The fire alarm system must be serviceable to alert the building’s occupants in the event of a fire. If not adequately serviced and maintained, the fire alarm system may not work as designed in an emergency, which will put lives and property at risk in the event of a fire. Moreover, the responsible person has a statutory duty of care to ensure that a “suitable system of maintenance” is in place to safeguard people to prevent loss of life.

Another reason for fire alarm servicing is to prevent needless false alarms that stretch the fire service and prevent them from attending to actual incidents and emergencies. Financial penalties can be levied against persistent offenders that have regular false alarms.

British Standards for Fire Alarm Maintenance

The British Standard BS 5839 states that Periodic inspection and servicing (every six months as per BS 5839-1) need to be carried out by competent persons with specialist knowledge of fire alarm systems every six months.

The Regulatory Reform (Fire Safety) Order 2005

UK Statutory regulations state that fire alarms must have suitable maintenance:

(1) Where necessary to safeguard the safety of relevant persons, the responsible person must ensure that the premises and any facilities, equipment and devices are provided in respect of the premises under this Order. Subject to paragraph (6), under any other enactment, including any enactment repealed or revoked by this Order, are subject to a suitable maintenance system and are maintained in an efficient state, in efficient working order and good repair.

Compliance With Statutory Regulations

The following guidelines will help you ensure that your fire alarm systems are adequately maintained to work as designed in an emergency and comply with UK statutory regulations.

  • Fire alarm systems should be maintained at least six months or more frequently, depending on the fire risk assessment requirements.
  • Suppose a fire risk assessment requires frequent fire alarm inspections and service visits. In that case, all interested parties should agree on the appropriate inspection schedule because the systems may be no longer compliant with British Standards.
  • The fire safety manual/logbook should maintain a record of all tests and checks, and any defects remedied should be kept in the fire safety manual/logbook.

The Competent Person (Fire Engineer)

  • All tests on equipment and trigger devices should be recorded in the logbook.
  • The competent person should carry out all fire alarm maintenance tasks following current Statutory requirements, regulations and the manufacturers’ recommendations.
  • The competent person should make a visual inspection to check whether structural or occupancy changes have affected the system’s compliance with the recommendations of this standard for the siting of manual call points, automatic fire detectors and fire alarm devices.
  • Check all manual call points remain unobstructed and conspicuous.
  • Check that all manual call points are fitted with a protective cover to access the frangible element.
  • Check if any new exits have been created without the provision of an adjacent manual call point; any new or relocated partitions have been erected within 500mm horizontally of any automatic fire detector.
  • Ensure that no storage encroaches within 300mm of ceilings; a clear space of 500mm is maintained below each automatic fire detector, and that the ability of the smoke detector to receive the stimulus that it has been designed to detect has not been impeded by other means.
  • Check if any changes to the use or occupancy of an area make the existing types of automatic fire detectors unsuitable for detection of fire or prone to unwanted fire alarms.
  • Check any building alterations or extensions that require additional fire detection and fire alarm equipment.
  • The building occupier should inform the alarm maintenance engineer of any structural or occupancy changes that might affect the detector’s siting or operation.
  • After any testing, the system should be left fully operational, including resetting any interlocks with plants and devices.
  • A competent person should check the records of false alarms under current British Standards. The rate of false alarms during the previous 12 months should be recorded and reviewed.


The above is an essential guide, but due to the nature of the varying specifications of fire alarm systems and their various components and devices, the competent person must carry out several further tasks to ensure that the fire system is fit for purpose.

Fire Alarm Maintenance for Different Fire Alarm Systems

It is vitally important that the correct fire alarm system is specified to ensure that it is fit for purpose and installed in accordance with UK statutory regulations to the relevant British standards as recommended in The Regulatory Reform (Fire Safety) Order 2005. All non-domestic buildings are covered in the act.

Meaning of “responsible person.”

“In this Order “responsible person” means—
(a)in relation to a workplace, the employer, if the workplace is to any extent under his control;
(b)in relation to any premises not falling within paragraph (a)—
(i)the person in control of the premises (as occupier or otherwise) in connection with the carrying on by him of a trade, business or other undertakings (for profit or not); or
(ii)the owner, where the person controlling the premises does not have control in connection with the carrying on by that person of a trade, business or other undertakings”.

Essentially, the responsible person, as defined under the act, must conduct a fire risk assessment to ascertain what fire protection systems are required to meet statutory law. However, UK legislation does not provide detailed information on how and what fire alarm and detection systems should be installed but will quote relevant British standards such as BS 5839. All fire alarm systems in the UK should be installed and maintained to BS 5839, which is the British Standard for Fire Detection and Fire Alarm Systems for Buildings. The standard provides recommendations on fire alarm design, installation, planning, commissioning and maintenance of fire alarms and fire detection systems.

Aspirating Smoke Detection Maintenance

Maintenance obligations, such as frequency and methods, should be considered per the manufacturer’s guidelines during system design. 

ASD systems, such as VESDA, Xtralis, Stratos and ICAM, all have a detector that samples the air conditions, looking for any smoke particles. The aspirating detector will pull the air through the pipework, circulating it to test for any smoke particles, indicating the event of a fire. ASD’s that do not clean the pipes during the maintenance run the risk of their fire alarm system generating false alarms or faults as the dust and dirt particles will block the sampling holes within the pipework and obstruct the filter. 

The pipes will have to be cleaned throughout the fire alarm maintenance visit to prevent this from taking place. An example of aspirating smoke detector maintenance checks include:  

  • Airflow reading during maintenance should be checked as ± 20% of the values calculated at commissioning.
  • Measurements of transportation time from the furthest sampling point (or dedicated maintenance test point) throughout maintenance should be confirmed to be inside + 15% or + 3 seconds, whichever is superior, of the exact measurement taken at commissioning.

Beam Detection

As a build-up of dust develops within a beam detector’s optical mechanisms, the sensitivity will increase and become more susceptible to false alarms. Most modern beam detectors include algorithms to compensate for this gradual build-up of dirt whilst retaining constant sensitivity to avoid false alarms. The beam detector lenses and reflector will still require periodic inspections and regular cleaning. Whilst legislation (BS5839-1) highlights the minimum servicing and maintenance visits required, the site’s conditions may determine the need for more frequent servicing.

Following the Manufacturers’ directions for cleaning methods is essential. A typical maintenance technique is to clean the detector lenses and reflector with a damp delicate cloth and a mild soap solution, generally avoiding all solvents.

Servicing and Maintenance Checks
Linear Heat Detection

Regular servicing and maintenance inspections must be carried out to ensure the Linear Heat Detection cable is not faulty and will function correctly in the event of a fire. Visual inspections ensure all support brackets and other fire alarm system components are compliant. The cable should be regularly checked for damage to the outer or inner core, as well as ensuring the neoprene insulators are installed correctly around the cable in the clips. Any junction boxes and created joints should be checked to guarantee they are reliable and correctly installed.

Electrical tests are required to verify that the circuit produced by the conductors is working. A linear heat detection system can not be checked using heat as this will damage the cabling. Therefore electrical tests are required to carry out the servicing and maintenance.

False Alarm Management

In accordance with BS5839-1

False alarms must be investigated so that actions can be implemented to minimise the chance of it happening again. Responsibility for the reduction of false alarms sits with every party who is involved with the specification, design, installation, commissioning, management at the operational level and maintenance of the fire alarm system. 

38,000 false alarms in London

In 2017, the London Fire Brigade attended 38,000 false alarms. This poses a serious problem as it’s a drain on the fire and rescue service and diverts them away from real emergencies. 

Once a fire alarm system has been installed and handed over to the client, the user must ensure that the building is managed to avoid unnecessary false alarms. This includes recording the following information for each false alarm:

    1. Date and time of the false alarm 
    2. Identification/location of the device at fault (if known)
    3. Category of the false alarm (if known)
    4. Reason for the false alarm (if known)
    5. Activity within the area (if the reason for the false alarm is unknown)
    6. Action taken on the cause of the alarm
    7. Whether the fire and rescue service were called and whether they attended 
    8. The name of the person responsible for recording the information

Periodic Inspections

As part of our fire alarm system maintenance checks and in accordance with BS5839-1, we will also carry out periodic inspections on the frequency of recorded false alarms and the reasoning behind why they occurred. This is to identify any faults within the system and correct these to avoid them happening again. 

Following the inspection and servicing visits, we will inform you of the outcome of the investigation with any recommendations on remedial works to minimise false alarms.

Fire Extinguishers
Fire Alarm Sounder Testing
Decibel level of fire alarm sounders

As part of the fire alarm maintenance, we will ensure that the sound level of the alarms is tested. Fire alarm sounders should be evenly installed throughout the premises to provide a sound pressure of 65 dB (decibels). This level is generally the minimum acceptable sound pressure level for fire alarm systems. To prevent any disorientation or hearing damage, installing a more significant number of quieter sounders is preferable to installing a few very loud sounders.

For wireless fire alarm systems, batteries must be tested and regularly replaced as they are utilised within the power supply for the sounders. Should a building suffer from false alarms when the premises are unoccupied, this can exhaust the batteries and leave the building with no operational fire alarm system.
