The integrated breakout system is compatible with the LB range and other profile systems to enable the doors and side screens to be manually ‘broken out’ in the event of an emergency event that requires the full clear opening to be provided for evacuation. The doors when linked into the fire alarm system will fail open and slide to the open position. The doors and side screens are hinged, allowing them both to be pushed outwards if the mass of people becomes too great for the door only opening. Even without the fire alarm connection and power, in the closed position, the doors are still able to be opened outwards. This facility can also have important commercial applications in Garden Centres, Cafes, Car Showrooms or any application where large items need to be transported and the conventional opening is insufficient.
