Fire Detection

Alarm services
Churchesfire offers a comprehensive design, installation, commissioning and maintenance service for all types of detection including single point smoke, heat and carbon monoxide detection, beam detection, wireless, air sampling (aspirated) and gas suppression systems. All work is carried out in accordance with the latest fire industry standards by our BAFE approved technicians.

Unless you can shout “FIRE” from any of the building’s fire exits and be clearly heard by everybody in the building, such as a single room building, you need a fire alarm. British Standards defines the category required for a specific risk, and your Fire Risk Assessment will specify the category of system required to meet your risk.

The categories of systems are as follows:  

M – Manual System

Category M systems are manual systems and rely on the occupants of the building discovering the fire and acting to warn others by operating the system. Such systems form the basic requirement for places of employment with no sleeping risk (Manual cover should be included in all Life Safety systems except L5 systems, where it may or may not be provided). 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. The precise classification depends on the nature of the area(s) provided with automatic protection  

L - Life Safety System

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 only. 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 owing to the presence of fire or smoke.

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 would relate to parts of the building considered to have a high level of risk or fire hazard.

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

P - Property Protection System

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 so as to minimise the time between ignition and the arrival of firefighters.
