CO Alarm Mode of Operation Operation of the Control Panel
3.10.2 How the Control Panel Indicates an Active Fire Control
Activation of a FIRE CONTROL point causes the control panel to do the following:
• Initiate the monitor module Control-by-Event
• Send a message to the LCD display, History buffer and installed printers, FDU-80
annunciators, and CRT-2s
• Display an
ACTIVE status banner and FIRE CONTROL Type Code on the LCD display, along with
information specific to the device
Figure 3.15 Sample Fire Control Point Display
3.10.3 How the Control Panel Indicates an Active Non-Fire Point
Non-Fire point operation does not affect control panel operation, nor does it display a message at
the panel LCD. Activation of a Non-Fire point activates CBE—but does not cause any indication
on the control panel. For example, you can program a Non-Fire point to turn lights in a zone to a
lower setting when activated. In this case, when the point activates the control panel activates the
point’s CBE to turn the lights down without any audio or visual indication on the control panel.
