Which control activates the emergency signaling system if the FAP LED screen is not functioning?

Explanation:
Emergency signaling is designed with a backup control so the alert can be activated even if the Flight Attendant Panel display is inoperative. The CMD control provides a direct path to trigger the emergency signaling system, bypassing the FAP, so the cabin and cockpit are alerted without depending on the FAP LED screen. The other controls are tied to evacuation procedures or to the FAP function and won’t reliably initiate the general emergency alert when the FAP is down.
