Protecting Occupants and Residents
The installation of a fire suppression system can ensure the property is efficiently protected in the event of a fire and can help to assist with the evacuation of residents, while also providing the fire service with an initial fire attack while they are en route.
At iMist, we have worked with many of the UK’s leading developers on HMO projects, including a 1,100+ nozzle installation at Bleriot Gate and in prestigious apartments, such as Great Peters Street in London.
Our engineers are experienced in overcoming the difficulties that installing in such properties can present. You’re in safe hands with iMist.
Why is a Fire Suppression System needed?
BSI: 9991 says you must have an AWFSS in the following circumstances;
188.8.131.52 Multi-Basement Buildings
For dwellings with multiple floors below ground level, a protected stairway, and an AWFSS, 9m meters should not be exceeded for from the foot of the
protected stair to any habitable room
6.4 (b) Dwelling Houses with one or more storey greater than 7.5m in height (4 storeys)
A second, separate protected stairwell is not required if AWFSS is fitted throughout.
9.1 (d) Internal Planning of Flats and Maisonettes
Flats or maisonettes with an open plan arrangement and more than one floor should have a protected stairway and AWFSS fitted. This allows escape to the shared external entrance.
9.4.2 (a) Extended travel distances within an open-plan flat
Flats more than 4.5m above ground level that are entered on the same level can increase total travel distances to the entrances from 9m to 20m with the
use of AWFSS throughout the entire building, along with a LD1 fire detection and fire alarm system in accordance with BS 5839-6:2013.
9.3 (b) Provision of inner rooms in flats not more than 4.5m in height
Inner rooms are not suggested unless the use of an AWFSS is utilised throughout the entire building, along with a grade D LD1 Fire detections and fire alarm system in accordance with BS 5839-6:2013.
9.7 Open Plan Layouts
Open planned flats are permissible with a fully fitted AWFSS.
