Notifier demonstrates acoustic skills for fire alarm system
An essential part of the fire safety system for a major retail and leisure development in Lewes was extensive acoustic modelling undertaken by Notifier working with the Honeywell life safety systems support team and Trinity Protection systems. The aim was to optimise the audibility and intelligibility of fire safety messages and other public announcements throughout the Trinity Leeds development.
It includes 120 food and retail outlets from 10 to 10 000 m2 and links the existing refurbished Trinity West shopping mall with the new Trinity East development via a large glass atrium.
The glass atrium and wide walkways provide a difficult acoustic space. Shaun Corbett, project director with Trinity Protection Systems, said, ‘Unlike most retail developments today, which are fully enclosed, this is in many ways an open-air environment — creating a very different acoustic challenge.
However, the results have been outstanding and far better than predicted, with a step change improvement in providing consistent all-round message quality across the whole of the Trinity Leeds site. This has been made possible thanks to Notifier’s advanced circuit and amplifier design.
The voice alarm/public address system is EN54 Part 16 approved and controlled by PAMMI (public address manual machine interface) a graphic user interface making control of the centre’s day-to-day announcements and background music simple whilst ensuring fire-related message take priority.
Each shop unit is liked to the Notifier fire-detection and alarm system.
