Summary
Left: one detection system controls four functions, so its failure removes all of them. Right: revised design with early automatic suppression and smoke doors on local detectors. Based on Australian Building Codes Board (2020b), p. 100.
Original illustration for Common cause failure, level 4 Expert.
- Source basis: Australian Building Codes Board (2020b), p. 100 (example: detection system raises alarm, activates smoke control, alerts fire brigade, releases hold-open smoke doors; total failure probability about 20 %; redesign with early automatic suppression in lieu of active smoke control and smoke doors on local detectors independent of the main system, detection system retained)
- Alt text: Two panels: left, one detection system feeds alarm, brigade call, smoke control and smoke doors; right, sprinklers and local door detectors added.
