Main photo for Abacus

The Abacus building in Birmingham has been redeveloped from its former 7 storey 1930’s coffee warehouse to create a stylish residential development, including 179 studio apartments. M&E Contractor P&R Morson chose SE Controls to provide a complete smoke ventilation package to create a healthier and safer environment for its internal occupants.

SE Controls designed and installed a natural smoke ventilation system in compliance with the building regulations smoke control guide Approved Document B, to provide heat and smoke extraction in the event of a fire. As the main escape routes for the occupants are via the common corridors and lobbies natural smoke ventilation was provided to remove smoke from these areas.

The system comprised a vertical smoke shaft that ran the whole height of the building and provided automatic automation of fire doors on each floor. A corresponding smoke detector was positioned at each zone of automation and would signal the OS2 control panel to power open the doors on the effected floor in the event of a fire. In conjunction to the opening of the smoke door a roof vent would power open the top of shaft to provide smoke extraction out of the building. As part of the new ADB the adjoining stair case needs to provide smoke ventilation via either a roof vent or AOV achieving a minimum free area of 1m2 at the top of the stair case.

SE Controls provided Repeater Panels on the ground floors of each block to provide system status information for each vent within the smoke ventilation system. Whilst this product is not required under ADB, SE Controls included this product within the specification to provide system status information in the event of a fire or for system maintenance.
