London Metal Exchange

Autograph Sales & Installations have completed a major upgrade to the failsafe paging system they previously installed at the London Metal Exchange, located in the heart of the City Of London.

Established in 1877, the London Metal Exchange (LME) is the world’s premier non-ferrous metals market, and as such sets future market prices, via futures and options contracts, for aluminium, copper, tin, nickel, zinc, lead, various aluminium alloys, steel billet, cobalt and molybdenum. The trading volumes are extraordinary, with some $15.4 trillion traded in 2011 (a new record for the LME), equivalent to $61 billion per day!

The continued expansion of the LME necessitated acquisition of further space and the new installation is essentially an extension of the existing security paging system to cover the extra areas. Top of the LME’s priority list was absolute reliability, a goal which is achieved by the installation of 100% dual-redundancy throughout the whole equipment list: every component is duplicated and linked via an Autograph ‘Signature Series’ switching unit, so that the backup system can be activated instantly if required.

The original equipment had proved its reliability since installation some years ago, and so the new system is a straight copy including MC2 T500 amplifiers, T-Line 100v transformers, Allen & Heath iDR8 processors and Penton RCS5 / FTS ceiling speakers. The Autograph Sales & Installations team were also required to meet the specifications of BS5839 as the system would also be required to deliver emergency evacuation messages to all LME personnel if necessary. As part of the final commissioning and testing process the team also submitted a report to the LME summarising the performance of the new equipment at various locations throughout the building prepatory to future refinements.
