Operation of the Control Panel CO Prealarm Event
2.7 CO Prealarm Event
The CO Pre-alarm function is used to receive an early warning of potential or incipient CO condi-
tions.
2.7.1 How the Control Panel Indicates a CO Pre-alarm
When a detector activates a CO Pre-alarm, the control panel does the following if there are no
higher priority unacknowledged events:
• Pulses the panel sounder (if the piezo is enabled)
• Illuminates the
OTHER LED (yellow)
•Displays
CO PREALARM in the upper left corner of the LCD, the type code and other
information specific to the detector as shown in Figure 2.8.
• Sends a CO Pre-alarm message to the History buffer, installed printer and annunciators.
• Activates CBE position 5.
• Activates Special Function Zone 19 (ZF19)
When an unacknowledged event with a higher priority exists, the control panel retains indications
of the higher priority event (the message, lit LED, audible tone, etc.) while flashing the
OTHER LED
and sending a CO Prealarm message to the History buffer, installed printer and annunciators.
The following is a sample screen for a CO Pre-alarm message.
Figure 2.8 Sample CO Prealarm Message
2.7.2 How to Respond to a CO Pre-Alarm Warning
If the control panel indicates a Prealarm, the operator can do the following:
1. Press the SILENCE BUZZER key to acknowledge the CO Prealarm.
2. Press the MORE INFO soft key to display the MORE INFORMATION screen and view
additional information on the device and possibly preprogrammed text for recommended
action. (Refer to Figure 1.9 on page 11 for an example of this screen and an explanation of its
fields.)
3. Investigate and correct the condition causing the CO Prealarm.
2.7.3 Interpreting Type ID Codes
The Type ID code that displays in a CO prealarm message is related to the type and function of the
detector point that initiates the CO prealarm. For example, a detector with a P
HOTO/CO Type ID
code means that the detector is a photo/CO type detector. If the Type ID code is unfamiliar, refer to
Appendix A, “Software Type ID Codes”, on page 63. This appendix is an alphabetical list of Type
ID codes and an explanation of each.
