Roller Shutter Fire Exit


Recommended Posts

No reference to roller shutters is included in BS 7273. It has been proposed to install a roller shutter door that is going to be a designated fire exit. The roller shutter will provide the only exit from an external enclosed area that forms part of the escape route away from the building to a place of ultimate safety.  I am considering accepting is as long as the installation complies with BS 7273 with the following three fail safe requirements: 1) It auto opens on power failure. 2) It auto opens on FA actuation. 3) A release mechanism is included in the installation with an emergency release device (green box) next to the shutter.  Your thoughts please?
