Fire detection system at National Indoor Arena can be configured to type of event
The upgrade to the fire-detection system at the National Indoor Arena enables the detection mode of a group of fire sensors to be changed according to the type of event.
Intelligent control panels supplied by Advanced Electronics are at the heart of the upgrade of a large fire-detection system at the National Indoor Arena in Birmingham. The NIA is one of the busiest large-scale indoor sporting and entertainment venues in Europe. It can seat up to 14 500 people, but flexible seating allows the layout to be adjusted. It also has four car parks. The upgrade was installed by BDS Fire & Security and consist of six Mx-4400 fully networked fire-control panels interfaced to over a thousand Apollo Discovery loop devices — including fire sensors, call points and I/O. The system also includes networked repeaters panels and Advanced’s PC-NeT graphics software. The extensive ‘cause-and-effect’ programming in the Mx-4400 panels controls over a hundred loop-driven I/O devices interfaced to automatic smoke doors, extract fans, catering-gas valves and access-control doors. The fire system is interfaced to the PA/VA system to form a fully integrated fire-detection solution to ensure staff and visitors are quickly and safely evacuated in the event of a fire. The PC-NeT graphics software runs on a standard PC connected to the fire network. This highly configurable system allows the use of site maps, images and text to display a visual representation of the fire system. Any device can be isolated or its analogue value obtained by clicking on an icon on the screen. Comprehensive event and alarm history logs can be viewed, and reports easily generated for analysis and auditing. As the use of the NIA changes from event to event, it will sometimes be necessary to change the detection mode of a group of fire sensors. This can be achieved quickly and easily from the PC-NeT software without having to program any of the fire panels. The six Mx-4400 panels are interconnected using Ad-NeT, Advanced’s fire network. The network can withstand a single fault between nodes without loss of communication to any single panel. This is all achieved using standard 2-core fire-resistant cable.
