The <a href="https://en.wikipedia.org/wiki/annunciator_panel" class="extiw" title="en:annunciator panel">annunciator panel</a> of a Cessna 441 Conquest is separated into two modules, with engine fire warning annunciators, engine fire extinguisher switches and an annunciator test switch between them. To the left of the left-hand module is a combined Master Warning annunciator and switch; the Master Warning annunciator flashes when any red annunciator in either module illuminates, pressing the Master Warning closes the switch which stops the flashing warning.
