Fire Alarm Systems


Your fire alarm system will form a major part in your building fire strategy, so making sure that the system is designed, installed and your fire alarms are maintained correctly is imperative; by working to the strictest British Standards 5839-1:2017 and BAFE SP203, Artius PP will support your commercial fire alarm system requirements from architectural plans through to installation and planned maintenance visits from one of our expert fire alarm engineers.


  • A bi-annual service of your fire alarm is carried out as a minimum requirement.
  • Any necessary works are carried out and recommendations considered for optimal performance.
  • All tests are carried out regularly, when necessary, and in accordance with commercial fire safety guidelines.
  • These services are carried out by a competent person.


You have a fire alarm installed at your premises to protect your building and its occupants. Legally, this must be serviced at least once every six months (according to BS 5839-1: 2017).

It is essential that this system functions properly as, in the event of a fire, this acts as an early warning, enabling safe and timely evacuation.

You are legally obliged to ensure that this detection system works and is in line with current regulatory standards. To do this, you must have fire alarm maintenance carried out by a competent person. On top of this, if your competent specialist/maintenance provider recommends replacements or repairs, it is the duty of the responsible person to ensure these works are carried out.

Artius PP is the best choice for your fire alarm maintenance, being a leading BAFE-accredited provider to hundreds of customers across UK.


During your maintenance visits, we’ll check and test the following before issuing you with a certificate report and any recommendations to be carried out:

  • Battery condition
  • Accuracy of zone plans
  • Heat and smoke detectors
  • Manual call points and zones
  • Radio signals (if radio/wireless)
  • Control panel functions and visuals
  • False alarms requiring investigation

Fabric of the building for changes and fire alarm compatibility

If you have monitoring on your fire alarm, we can also maintain this for you, ensuring the signalling connection between your alarm and the receiving centre is performing at its optimal level. If you have emergency lights, fire extinguishers or other fire safety products in place to protect your building, we can maintain these for you as well.

Fire Alarm System Types

Fire Alarm Categories

M – Manual System

Category M systems are manual systems and rely on the occupants of the building discovering the fire and operating the system to warn others. Such systems are a basic requirement in places of employment with no sleeping risk

In addition to manual means of triggering an alarm, L category systems will also normally have an element of coverage using automatic fire detection such as smoke or heat detectors.

L - Life Safety System Category 5


Category 5 systems are the ‘custom’ category and relate to certain special requirements that cannot be covered by any other category. Where such systems are specified, careful reference must be made to the objective of the cover, normally from a fire risk assessment.

L4 - Life Safety System Category 4

Category 4 systems cover escape routes and circulation areas. Detectors might be sited in other areas of the building, but the objective is to protect the escape route.

L3 - Life Safety System Category 3

Category 3 systems provide more extensive cover than Category 4. The objective is to warn the occupants of the building early enough to ensure that all are able to exit the building before escape routes become impassable.

L2 - Life Safety System Category 2

Category 2 systems relate to automatic fire protection in defined areas of the building as well as satisfying the requirements of Category 3. The wider cover relates to parts of the building considered to have a high level of risk or fire hazard.

L1 - Life Safety System Category 1

With Category 1 systems, the whole of a building is covered with minor exceptions.

P2 - Property Protection Category 2

Category 2 systems provide fire detection in specified parts of the building where there is either high risk or where business disruption must be minimised.

P1 - Property Protection Category 1

The system is installed throughout the building – the objective being to offer the earliest possible warning of fire to minimise the time between ignition and the arrival of firefighters.
