Multiple Houses
Fire Safety System

With multiple housing estates and property developments, it is vital to meet the appropriate building regulations with regard to fire safety.

Protecting Housing Development Owners

Multiple housing estates and multiple apartment developments are increasingly popular across the country. These types of large developments can often present difficulties for developers and designers, especially with regard to open-plan layouts, extended travel distances and fire brigade access in the event of an emergency. When the properties are too far from the nearest accessible road (45 metres), a fire suppression system may be needed.

iMist™ has worked as succesful fire suppression in multiple houses across the UK with completion ranging from 1-18 months. The many advantages of the iMist™ system allow architects to design properties that meet their clients’ requirements, while still maintaining code compliance and adherence to fire regulations.

Why is a Fire Suppression System needed?

BS:9991 says you must have an AWFSS in the following circumstances;

 

5.2.1.2 Multi-Basement Buildings

For dwellings with multiple floors below ground level, a protected stairway, and an AWFSS is required. 9 meters should not be exceeded 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 detection 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.
