Design, Installation and Commissioning
All fire alarm systems should be designed to comply with BS5839 to ensure that manual call points, automatic detectors and sounders are installed in the correct positions to give you adequate protection. There are different levels of detection that can be specified in fire alarm systems and they are defined by categories below.
Category L1 system
should include automatic fire detection in all rooms, on all escape routes and in all voids over 600mm in height. This system is designed to allow persons to escape from the building at the earliest opportunity
To arrange a quotation for new extinguishers or for routine maintenance of existing extinguishers please contact us.
Category L2 system
should include automatic fire detection on all escape routes and rooms leading onto escape routes. An L2 system can also include additional areas deemed as a high risk not included in the escape routes and adjoining rooms, such as boiler houses.
Category L3 system
is very similar to a category L2 system in that automatic fire detection should be positioned on escape routes and adjoining rooms, although it does not have to include for additional areas deemed to have a high fire risk.
Category L4 system
includes automatic fire detection on escape routes only, and not in the adjoining rooms as per the L2 and L3 classifications.
Category L5 system
is designed for buildings that have a particular fire risk in specific areas. For example if there is an area of high fire risk which is considered worthy of having some automatic detection but a manual system is also needed, then this will be termed as L5/M.
Category M System
is a manual operation only system which has call points on all exits as well as corridors.
Category P1 system
is designed to provide the earliest possible warning of a fire by including automatic detection in all areas of the building and enabling the fire brigade to attend at the earliest opportunity
Category P2 system
is designed to protect defined parts of the building only. These defined parts of the building may be areas with a high fire risk.
Routine Maintenance
All fire alarm systems require routine testing and inspection, in accordance with BS5839 the minimum period for these inspections is six monthly. At this time detector are tested for correct operation as are the fire alarm controls sounders, stand by batteries and ancillary outputs.
