Pyrotenax mineral-insulated (MI) cables have been installed for fire-rated applications in the striking new 19,000m2 landmark office development at 1fifty Cheapside, overlooking St Pauls Cathedral. Specified by Hilson Moran and installed by Haden Young as the backbone system for landlord services in the shell and core, Pyro MI is being employed in circuits for both life safety and fire fighting rated applications, as defined in BS7346-6 Specification for Cable Systems.
MI is recognised as the highest performing fire-rated cable technology and the Pyro MI cable has undergone Lloyds Register witness testing under the most stringent fire test methodology of BS 7346-6:2005 and successfully achieved the highest performance requirement of 120 minutes survival time for fire fighting systems. This ensures that it comes with an assurance for those responsible for cable specification and purchase that they are meeting the requirements of the Regulatory Reform Order (RRO) in regard to the material supply.
At 1fifty Cheapside, a range of heavy duty Pyro MI cables (up to 1H185) has been employed for the fire rated power applications encompassing: sub-mains for life safety systems; fire fighting lifts; fire interface to mechanical equipment and panels; extract fans; motorised smoke dampers; sprinkler pumps and fire alarm panel supplies. For the fire-rated communications applications, including voice alarms and all fire telephones, over 30km of light duty Pyro MI cable has been installed. All were supplied to the project through WF at Dagenham with logistical support from the manufacturer, Tyco Thermal Controls.
1fifty Cheapside is a St Martins Property Corporation Ltd development, due for completion in summer 2008. It has 8 floors of commercial office space above retail units on the ground and lower ground levels. The building has achieved an excellent BREEAM rating and is a dynamic addition to the City’s office environment.
