SE Controls provides safe environment at Holy Rosary School’s new entertainment hall

A new 1000 seat multi purpose entertainment and sports centre at Holy Rosary School in Johannesburg is using precision automatic window actuators and control systems from SE Controls, to provide effective smoke ventilation in the event of a fire.

Bishop Shanahan Hall is the latest addition to the Catholic day school, which was founded in 1940 and provides private primary and high school education for girls from Grade R to 12 in a range of subjects including languages, mathematics and sciences.

Designed by Dual Design Architects and built by JTSON Construction, the extensive new hall was conceived as a multi-use building that could stage, formal events, indoor sports, competitions, student dances and entertainment, as the school had outgrown its existing facilities, which could no longer accommodate large audience functions.

While Bishop Shanahan Hall provides the highest standard of staging and equipment for events, safety for students, performers and the audience is also at the core of the building’s design, particularly if a fire should occur. The smoke ventilation solution formed part of the rationale behind the overall fire system design, which was prepared by Building Code Consultants (BCC).

To ensure the various escape routes are kept smoke free and assist evacuation, windows in the building are automatically actuated by SE Controls’ compact SECO N 24 40 - 800mm stroke chain actuators, which are fire safety tested to the internationally recognised EN12101-2: Annex G standard.

In addition to the 12 SECO N 24 40 actuators, supplied by SE Controls’ South African operation, which has offices in Durban and Johannesburg, specialist contractor Robertson Ventilation Industries (RVI), installed and commissioned four manual control point (MCP) fireman’s override switches together with 2 x OS2 Type 23 controls panels to control the MCPs and actuators while also linking them to the school’s fire safety system.

Russell Cramb of SE Controls Africa explained: “In addition to providing an effective smoke control solution, our actuators were also specified for this project as the architects wanted them to be almost silent and virtually invisible. To comply with this, each SECO N 24 40 unit was powder coated to match the window frame colour, while the low profile design of the actuator body enabled them to be sill mounted to keep them out of sight.”

Exclusive smoke ventilation solution from SE Controls for London’s Marconi House

London’s prestigious Marconi House apartment and hotel development, which is already set to be one of the capitals most sought after addresses, is using an advanced SHEVTEC® smoke and heat exhaust ventilation system from SE Controls to provide smoke free escape routes for residents and staff in the event of a fire.

Located on The Strand, the building has a long and varied history, originally housing the Gaiety Theatre’s restaurant before being redeveloped as the headquarters of the Marconi Wireless Telegraph Company and being chosen the location for the BBC’s first landmark radio broadcast in 1922.

The latest phase in its evolution, which has been designed by Foster & Partners includes the construction of a five star 157-bedroom hotel linked to and exclusive development of 86 apartments behind the original stone façade that still bears the Marconi name. Alongside this, the five star hotel development provides 157 bedrooms, which is served by a separate and completely independent SHEVTEC smoke ventilation system.
 

As each building has different layouts and specification, SE Controls worked closely with Lloret Fire and Security on the hotel development and Nomico/Galliard on the apartments to create smoke ventilation solutions dedicated to the apartments and hotel while integrating fully with the fire alarm systems.

SE Controls was responsible for the supply, fitting and commissioning of the North and South stair smoke shaft control systems, involving the installation of SHEVTEC automatically opening smoke shaft door actuators on each of the apartment block’s eight levels, primarily to provide pressure relief to the stair core pressurisation systems and passive smoke extraction to the communal lobbies when activated by the fire alarm.

The actuators are controlled by OS2 control panels, which are located on each floor together with tamper proof manual control points (MCP) for use by fire service personnel. Two repeater panels are also installed in the concierge area and the fire control room to provide a constant display of status and activation in the event of a fire.

Within the hotel, smoke ventilation is handled by two smoke shafts with one located in the North stairs and the other dedicated to the ten floor bedroom corridors, which also provides natural ventilation to the building in normal operation.

The extensive SE Controls’ solution incorporates SHEVTEC automatic multi-blade dampers on each floor, including basement levels, together with 28 OS2 Type 21 controllers, 31 fire servicetamper proof MCPs and reset points two repeater panels to provide full status monitoring. All systems used within the SE Controls system are CE marked and conform to the latest legislation requirements for performance, fire safety and operation including the EN12101 and BS9999 standards.

In normal operation, all dampers are open to provide natural ventilation, but automatically close when activated by a signal from the fire alarm system except for the damper located on the floor where the fire has started. This provides pressure relief to the staircase system and enables smoke to be vented from the fire floor, while stopping any cross contamination onto other floors and allowing smoke free escape to be possible on all floors.

Fire service manual control points are located next to each damper to enable control of the vent by fire officers. If a fire should occur on any non-bedroom floors, the system is configured so that all dampers will close to allow evacuation, while still allowing Manual Control Point override.

SE Controls’ Managing Director, Will Perkins, commented: “The developers have not only focused on the quality of the facilities, services, construction and finish within Marconi House, but also on the fire safety strategy and its vital role in ensuring the safety of residents, staff and hotel guests. Smoke ventilation is a vital element in this process and I’m delighted that we were able to put our extensive experience in residential smoke ventilation systems to use on this prestigious development.”

SE Controls wins ‘historic’ award from The National Archive

A major project to replace and upgrade the glazed roof at The National Archive (TNA) in Kew has resulted in SE Controls’ smoke ventilation solutions being recognised within TNA’s Team Awards, which have been awarded collectively to the internal departments, external partners and contractors involved in the successful completion of the project.

The National Archive is the central repository for all UK historic and government records covering almost 10 centuries of information going back to the Domesday Book of 1085. As a result, while the safety of the building’s staff and visitors is the critical concern in the event of a fire, it is also vital that the archive is protected from damage.

By replacing the existing roof glazing, which had begun to leak in a number of places, TNA took the opportunity to improve the overall quality of the glazing, as well as bringing the smoke ventilation and actuation system up to the latest regulatory standards to ensure compliance with the relevant fire safety and building legislation.

The previous pneumatically controlled smoke vent and window automation system was replaced with a new integrated window and actuator solution, which is fully compliant to the latest EN12101-2 standard and is linked to SE Controls’ smoke and environmental control panels within the building’s eight smoke control zones.

HTP Architects designed the new glazed roof and Structura UK was the principal contractor on the project, with both companies also being part of the collective award from TNA. Throughout the project, the entire upgrading was undertaken while the building was occupied and provided full access to the public to ensure no disruption was caused.
