System Status 2. Determine the system status. For most problems, one or more alarm
and status LEDs will be illuminated. Depending on the controller
type, the following will be displayed:
– system voltage (all)
– system current (Millennium)
– system mode (Millennium)
– system number of alarm/warnings (Millennium)
If the screen is blank, but alarm and status LEDs are illuminated,
call technical support.
If the entire panel is blank, check the controller fuse (F3 basic
power for the Millennium; F2 on the BLJ board for the Vector).
See Figures 12-3 and 12-5. Verify that the controller is getting
power. If not, replace fuse. If the display is still blank, call
technical support.
Alarms Menu 3. To view the Alarms Menu:
• Millennium controller:
If the default screen appears normal, press the MENU button.
The main menu appears with “Alarms” blinking. Press ENTER
to obtain the Alarms menu. Additional data appears that will
help to identify the problem.
• Vector controller:
Press the View Active Alarms button and use the displayed
message code to help identify the problem.
