3.8 Pre-Alarm Warning Mode of Operation
3.8.1 How the Control Panel Indicates a Pre-Alarm Warning
The control panel activates a Pre-Alarm Warning if a detector exceeds the programmed Pre-Alarm
Alert or Action level. When a detector activates a Pre-Alarm, the control panel does the following:
• Pulses the panel sounder
• Flashes the PRE-ALARM LED
• Activates the Pre-Alarm zone (F9)
• Sends a Pre-Alarm message to the LCD display, History buffer and installed printers, FDU-80
annunciators, and CRT-2s
• Displays a pre alarm status banner, the Type Code of the detector, and the Pre-Alarm level
(Alert or Action) on the LCD display, along with information specific to the device as shown
in
Figure 3.11.
