Guest Jay Taylor Posted February 14, 2017 Report Share Posted February 14, 2017 Do you have to have a separate fire alarm zone for the attic/loft area to the floors below? I know Zones should not cross floors but is the attic/loft classed as a separate floor? Quote Link to comment Share on other sites More sharing options...
AnthonyB Posted February 14, 2017 Report Share Posted February 14, 2017 BS 5839-1:2013 13.2 Recommendations 13.2.1 Recommendations applicable to all detection zones b) If the total floor area of the building is greater than 300 m2, each zone should be restricted to a single storey. d) For voids above or below the floor area of a room, these may be included within the same zone of the room, provided that the voids and the room constitute a single fire compartment. Depends whether you class it as a void or a floor. If the space is used and has an access ladder/stair I would be leaning towards calling it a floor, if a disused space more likely a void, but in the case of the latter would want remote indicators fitted.
