CO Alarm Mode of Operation
Operation of the Control Panel
3.9.2 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

information specific to the device
Figure 3.11 Sample Fire Control Point Display
3.9.3 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.
3.10 CO Alarm Mode of Operation
3.10.1 How the Control Panel Indicates a CO Alarm
When an initiating device (detector or monitor module) activates due to a CO alarm event, the
control panel does the following:
•
Produces a pulsed audible tone
•
Displays a CO alarm event that indicates the type of device that activated the fire alarm
•
Displays
ALARM
in the status banner on the LCD display, along with information specific to
the device, as shown below:
Figure 3.12 Sample CO Alarm Display

Sends a CO Alarm message to the LCD display, remote annunciators, History buffer, installed
printers, and CRT-2s.

Latches the control panel in CO alarm. (You can not return the control panel to normal
operation until you correct the CO alarm condition and reset the control panel)
•
Initiates any Control-By-Event actions—activiates ZF18
