Fire Alarm Systems

Fire alarm systems maintenance and servicing has been at the core of the Churches Fire & Security for the last 30 years, building a strong network of expert fire technicians across the UK. Because of our long-standing expertise we can deal with many different types of fire alarm systems, offering excellent servicing contracts to our customers.


Why are fire alarms required?

Fire alarms are required in most buildings, in accordance with the Regulatory Reform (Fire Safety) Order and the Fire Risk Assessment.

How often do fire alarm systems need to be tested?

In compliance with UK law, fire alarm systems for businesses should be tested regularly to ensure their effectiveness and reliability. Typically, fire alarm systems should be tested at least once every six months by a competent person, as stipulated by the Regulatory Reform (Fire Safety) Order 2005. Additionally, regular maintenance and servicing are crucial to keep fire alarm systems in optimal working condition and to identify any potential issues promptly.

How do you determine what fire alarm is required?

British Standards defines the category required for a specific risk. Churches Fire & Security will work with you to develop a Fire Risk Assessment that will specify the category of system required to meet your risk.

Types of fire alarm systems

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.


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.

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.

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 fire alarm system requirements or 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 fire alarm system requirements ensure that the whole of a building is covered with minor exceptions.

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.

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.
