CONFIGURING AND STATUS DISPLAY INSTRUCTIONS Status display The Terminal Equipment Controller features a two-line, eight-character display. There is a low level backlight that is always active and can only be seen at night. When left unattended, the Terminal Equipment Controller has an auto scrolling display that shows the current status of the system. Each item is scrolled sequentially with the back lighting in low level mode. Pressing any key will cause the back light to come on to high level.
If alarms are detected, they will automatically be displayed at the end of the status display scroll. During an alarm message display, the back lit screen will light up at the same time as the message and shut off during the rest of the status display. Two alarms maximum can appear at any given time. The range of zones that can be in alarm is 1 to 253.
When left unattended for 45 seconds, the display will resume automatic status display scrolling. To turn on the back light, press any key on the front panel.
