Pressing the System Reset switch turns off all control modules and Notification Appliance Circuits, tempo-
rarily turns off resettable power to 4-wire detectors, causes an 'All Systems Normal' message to be dis-
played on the LCD, and stores 'System Reset' in the printer and history file. It also turns on all LEDs,
piezo, and LCD display segments as long as SYSTEM RESET is held (lamp test). Any alarm or trouble
that exists after System Reset will resound the system.
