DORMA door controls, automatics, and glass fittings have been installed in the new expansion to the Darwin Centre at the Natural History Museum.
DORMA TS92, TS93, and ITS96 cam-action door closers were specified by architect CF Moller, due to both their low opening forces in accordance with BS8300 and their aesthetical design, which is in keeping with the overall style of the Darwin Centre.
The TS92 and TS93 cam-action closers have been installed with the electro-magnetic hold-open feature and have been designed to remain open, closing automatically if the fire alarm is triggered. Offering the illusion of an invisible closer, the ITS96 is a concealed cam-action closer hidden within the door leaf and frame, complementing the overall modern and sleek design of the new centre.

DORMA BTS 75V and BTS80 floor springs also feature at the redevelopment. These universal floor springs feature a hydraulically controlled closing cycle, adjustable closing speed and mechanical backcheck. A comprehensive programme of accessories ensures that they can be used successfully with a wide variety of door constructions and floor coverings.
Also installed at the new Darwin Centre is DORMA’s ED200 – an automatic swing door operator that offers an optimum solution for safety in high traffic areas. During an emergency, fire doors and exit doors must continue to open for people to exit, but close firmly to prevent the fire or smoke spreading. With the ED200, its unique package of safety, security and interfacing features means that when a fire alarm is actuated, or when the power is cut, the closer will revert from automatic to manual operation with a hydraulically dampened spring close action.
Opening to the public in September 2009, the new 8-storey, £78 million landmark building completes the Darwin Centre expansion, which is the most significant development at the Natural History Museum since it moved to South Kensington in 1881. The new centre will become home to the museum’s vast collection of bottled specimens and will offer state-of-the art scientific research facilities.
