Do you need help keeping your staff and pupils safe ?
We are experienced in designing and installing fire alarm systems in educational settings, as well as commercial, in line with the rating that is determined by your risk assessment.
Although modern buildings will be built with fire detection, there are still many older premises whose level of coverage can be extended or instances where an upgrade to an addressable system is required. Perhaps a change of use of certain areas or a building extension mean that your current system does not provide the coverage you need.
We are able to work with you to provide the best solution for your premises. We have experience working with consultants in instances where funding has been secured for fire system updates, extensions or installations. Large installations may require that CDM requirements are met and our team are familiar with this legislation.
Below is a guide to fire systems which may help you to understand the ratings and types that your risk assessor will recommend.
Types of systems
Each device will have an address. This makes it quicker to identify the exact area where a fire may have started, which is safer for the pupils, staff, site team and fire brigade and means that it is quicker to put out a fire. These addresses will be separated into zones.
The devices do not have exact locations but will still be separated into zones. This can make fault finding on older systems more difficult and a fault within the zone can cause all detectors after this point to fail.
An L2 or L3 rated system is most likely to be recommended in a school’s Fire Risk Assessment.
– An M rated system provides a Manual Alarm only. An example of this is break glasses only. This manual form of activation should also be incorporated within all L rated systems. An M rated system would not be recommended for a school in modern times, but many schools were built with this form of system in the 60’s to 80’s.
– An L4 rated system includes detection in the main fire escape routes. This would be the corridors, fire escape and the top of stairwells on main landings.
– An L3 rated system includes detection in all fire escapes and stairwells. It includes the coverage in an L4 system and extends to all corridors, passageways and stairwells, rooms over 4m in length which open onto escape routes and the top of vertical risers, such as lift shafts.
– An L2 rated system includes detection in specified areas where a fire could lead to a high risk to life. It covers all areas that an L3 system would cover and also includes sleeping areas, areas with a risk of ignition and areas where there may be vulnerable individuals.
– An L1 system covers all areas except the toilets and bathrooms, small cupboards, stairway or toilet lobbies and small voids.
