Globally Acknowledging Troubles
If global acknowledge is enabled on the FACP, the system automatically clears after the source of the trouble clears. Shortly after the
source of the trouble clears, the display should indicate a normal system.
Note:
Pressing a button within 30 seconds of clearing the source of the trouble will delay the change of display screens. The display will
change 30 seconds after the last button pressed.

3.

Restore or replace the defective device (e.g., a switch, wire, or notification appliance.) in accordance with the device's instructions.
The trouble condition automatically clears when the problem has been corrected.
