D+H UK have supplied and installed window drives and controls for a natural smoke ventilation system at an office development in Shenley Wood, Milton Keynes.

D+H UK’s work was focussed within the building’s large atrium, around which individual offices and two courtyards are arranged.

20 Schuco AWS 57 RO bottom hung outward opening roof vents were installed above the atrium.

D+H UK supplied and installed a ZA 85/1000 high speed linear drive to each roof vent.

In the event of a fire, all vents power open fully within 60 seconds and provide the required aerodynamic free area to ventilate the atrium of smoke.

D+H UK provided CE marking and a Declaration of Performance for the vents to comply with EN12101-2.

A CPS-M natural smoke ventilation control panel (with built in battery back up) operates the vents.

The CPS-M operates all 20 vents simultaneously in the event of fire. Dyer’s system includes a single zone break glass unit to manually trigger, test, reset and monitor the system.

D+H UK’s ongoing maintenance contract with Shenley Pavilions ensures that regular servicing takes place to prolong the life of the system by actioning early signs of fault/wear and tear where necessary.
