Control panel operations
The control panel operates in either normal mode or off-normal mode.
Normal mode
The panel operates in normal mode in the absence of any alarm, supervisory, trouble, or
monitor events. In normal mode, the control panel monitors the system. The panel and LCD
remote annunciators display the time, date, and banner text, if programmed.
Off-normal mode
The panel operates in off-normal mode any time an event is introduced into the system. When
this happens, the panel:
• Changes contact positions on appropriate common relays
• Activates alarm outputs (for alarm events only)
• Turns on the appropriate LEDs and the panel buzzer
