Sound Safety On Dlr

摘要

The voice alarm and public address system at the new Woolwich Arsenal station has been supplied and installed by PEL Services. Part of the extended DLR (Docklands Light Railway) in East London, Woolwich Arsenal provides an alternative way to cross the River Thames.rnThe system installed by PEL comprises a BoschrnPraesidio digital public address and emergency sound system, linked to Penton column speakers in the concourse and Penton projection speakers on the platforms. There is also a zoned station microphone located in the station operations room for general announcements, plus local station microphones at passenger emergency points for use by station staff at platform level. All equipment was chosen to provide the best audibility for announcements, with ambient noise sensing automatically adjusting the volume of announcements to cope with changing noise levels. The fact that all equipment can be contained in one rack was an important consideration with space at a premium.
