Operation of the Control Panel Disabled Points Mode of Operation
3.9 Disabled Points Mode of Operation
The control panel indicates disabled points by displaying a screen for each disabled detector,
monitor module, and control/relay module. Disabled points do not cause an alarm or any
Control-by-Event activity. If more than one point is disabled, the control panel automatically
displays by priority, mimicking the alarms.
When one or more points are disabled, the control panel does the following:
• Holds all disabled output points in the off-state
• Flashes the SYSTEM TROUBLE LED
•Lights the POINT DISABLED LED
• Sends a Disabled Point message to the LCD display, History buffer and installed printers,
FDU-80 annunciators, and CRT-2s
• Displays a message for each disabled point
