Design, supply, installation and 10-Year maintenance of a fully integrated fire detection and suppression system at king shaka international airport (fale) atns operations centre and bluff radar site

FALE ATNS Operations Centre hosts air traffic control operations. The main building contains offices, a control tower cab, a kitchen, a reception/foyer, workshops and ablution facilities. Management, engineering technicians, administrative staff and South African Weather Services employees are based on the ground floor. Air traffic controllers work from the approach radar hall and the control tower cab.

The existing main building system is fire detection and alarm, with the FACP in the ground floor foyer. Equipment rooms and the UPS room house high-value ATNS equipment. Cabling runs through ground floor floor voids (equipment rooms and passages), Level 14 and Level 16, and control tower shaft cable ducts; these areas have both detection and suppression.

The Operations Centre has a new RCF PA System (SE5120/SE5121 Life Safety Voice Alarm System). ACSA will install a separate FACP in the guardhouse outside the Operations Centre.
