Project: Langley Academy
The fire strategy for Langley required all entrances and all compartment doors to open automatically to 90 degrees when signalled by the fire alarm. At all other times, they were to remain closed [FD60]. Entrances had to remain locked [keypad access] but would unlock remotely and fly open. There were also four individual classrooms at the end of the <<fingers>> which similarly would be lockable FD60 fire doors with overhead door closers but which when signalled to do so would unlock, reverse and open automatically in the event of a fire.
Doors were either solid core timber with vision panels or steel, fully glazed.
Working with Dorma Door Controls and with valuable advice from both Fosters and Wates, Scott Beaven were able to adapt Dorma TS83 surface overhead door closer to accept a fire alarm signal enabling the device to function as a conventional overhead door closer day-in, day-out but automatically reverse, and open, and hold at 90 degrees when actuated by the fire alarm. Doors were fitted with motorised locks [also by Scott Beaven] which unlocked instantly and simultaneously.
Actuators were colour powder coated dark grey to match door frames and other metal elements within the building.
