We have installed an Analogue Addressable Fire Alarm and Fire Telephone System at the Millennium Stadium Cardiff. The fire alarm system comprises of seven Advanced Electronics multi loop controllers networked together using a fault tolerant network. The front end is controlled by a graphics package operated from the main security lodge and stadium control room. Some 2400 Apollo Discovery devices are being installed throughout the stadium, Apollo Discovery was chosen due to its high specification and tolerance to environmental conditions and unwanted alarms.
