28 AFP-3030 Operations Manual — P/N DOC-01-033:C 05/12/2018Operation of the Control Panel CO Prealarm Event2.7 CO Prealarm EventThe CO Pre-alarm function is used to receive an early warning of potential or incipient CO conditions.2.7.1 How the Control Panel Indicates a CO Pre-alarmWhen 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 inFigure 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 mes-sage, lit LED, audible tone, etc.) while flashing the OTHER LED and sending a CO Prealarm message to the History buffer, installedprinter and annunciators.The following is a sample screen for a CO Pre-alarm message.Figure 2.8 Sample CO Prealarm Message2.7.2 How to Respond to a CO Pre-Alarm WarningIf 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 andpossibly preprogrammed text for recommended action. (Refer to Figure 1.9 on page 14 for an example of this screen and anexplanation of its fields.)3. Investigate and correct the condition causing the CO Prealarm.2.7.3 Interpreting Type ID CodesThe Type ID code that displays in a CO prealarm message is related to the type and function of the detector point that initiates the COprealarm. For example, a detector with a PHOTO /CO Type ID code means that the detector is a photo/CO type detector. If the Type IDcode is unfamiliar, refer to Appendix A, “Software Type ID Codes”, on page 53. This appendix is an alphabetical list of Type ID codesand an explanation of each.2.8 Mass Notification Alarm Event2.8.1 How the Control Panel Indicates a Mass Notification AlarmWhen an Mass Notification initiating device (monitor module) activates, the control panel does the following:• Produces a steady audible tone (if the piezo is enabled)• Does not activate the System Alarm relay(s).• Illuminates the OTHER LED• Displays MN ALARM in the upper left corner of the display, a Type Code that indicates the type of device that activated the alarm,and other information specific to the device. The message occupies the top four lines of the screen, replacing the System Normalmessage as shown in Figure 2.9 below. Refer to “Mass Notification Events” on page 11 for a full description of each message field• Sends an MN Alarm message to the History buffer and installed printer and annunciators• Latches the control panel in MN alarm. (You cannot return the control panel to normal operation until you correct the alarmcondition and reset the control panel). If a fire condition is present on the control panel, a second system reset may be required toclear the MN alarm, depending on MN Priority programming. Refer to the AFP-3030 Programming Manual.• Activates any devices programmed as General Pending• Activates special zone ZF20.O T H E R : 2 O F 2P R E A L A R M 1 2 0 % O F F I R E S E N S I T I V I T Y L E V E L 4E L E V A T O R L O B B Y E A S T W I N GF I R S T F L O O R D O O R S M O K E ( P H O T O )1 0 : 3 5 : 1 7 A T U E 2 2 J A N 2 0 1 9 L 0 1 D 1 3 4M O R E I N F O . . .1 O T H L 0 2 D 0 0 3D e t e c t o r L 0 2 D 0 0 32 O T H L 0 1 D 1 3 4D e t e c t o r L 0 1 D 1 3 4A L M : 0 S U P : 0 F L T : 0 D I S : 0 O T H E R : 21 1 : 5 8 : 4 3 A T U E 2 2 , J A N , 2 0 1 9
