A sequencer system for an ejection assembly may comprise a first A-side controller and a second A-side controller in operable communication with the first A-side controller. A first B-side controller may be in operable communication with the first A-side controller. A second B-side controller may be in operable communication with the first B-side controller and the second A-side controller. The controllers may be configured to each make an initial ejection sequence determination and a verified ejection sequence determination. The controllers may make the verified ejection seat determination based on a two of three voting scheme.
