Fire exit via roller shutter

[firestop]

Looking at the problem doesnt give any notion of other available exit routes and travel distances. Would it be at all possible to discount the door as a means of escape and direct people to another door, taking into account travel distances and travel through partition walls to another fire compartment. Just an idea instead of trying to solve electrical problems and counterbalance thingys.

Its just a thought but Ive seen similar applications at large retail outlets, (B&Q), where the roller shutter door, approx 5 metres in width, is left open for "Heavy / Bulky collections, the entrance is manned by B&Q personnel, (Management Control over theft etc) and the weather is kept out by see-through vertical plastic flaps, allowing pedestrian & forklift movements. Clearly this can be counted as an emergency exit if required as it is available during all times of occupation.  I invariably try to suggest an interface of Management Control or Responsibility before I reccomend a company spends big bucks on material alterations where I can on FRA's. Does this help?
