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.
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)
