Section 4: Operation; Mass Notification Events; 1: Mn Alarm - Honeywell Notifier NFS2-3030 FACP Programming And Operations Manual

4.1 Mass Notification Events

Special zones ZF20 (MN alarm), ZF21 (MN supervisory), and ZF22 (MN trouble) are used to signal mass notification events locally and
over Noti•Fire•Net. If MN has the highest priority in the system, a ZF20 (MN alarm) will suppress fire locally and for every node in the
initiating node's MN map.
4.1.1 MN Alarm
Activating an MN Alarm
An MN alarm can be activated by any of the following events:
1. Paging at the MN level.
2. Activation of an MN Alarm Type Code on an ONYX panel.
3. Pressing an annunciator or DVC-KD control point programmed to activate an MN alarm message.
NFS2-3030, NCA-2 MN Activations

Local Activation
When an MN alarm activates locally, it:
• Produces a steady audible tone if the piezo is enabled.
• Flashes the "OTHER" LED for NFS2-3030/NCA-2.
• Does not activate the alarm relays.
• Displays MN ALARM in the upper left corner of the display of NFS2-3030, NCA-2, and LCD-160, as well as other information
specific to the alarm. Displays as MN ALM on LCD2-80/LCD-80 in terminal mode.
• Activates Special Function Zone ZF20 (MN alarm zone).
• Suppresses fire alarms if MN has the highest priority (refer to "Output Event Suppression" on page 40)
• Activates "General Pending" type code at the NFS2-3030.
• Does not activate "General Alarm" or "Alarm Pending" type codes.
• Is acknowledged individually.
• Scrolls using "Other Event/Scroll Display" key.
• Any device programmed for "Resound by Fire" will not resound.
• Increments the OTHER counter in the event counts display.
• Sends an MN alarm message to the history buffer and installed printer and annunciators.
• Appears as "MNA" in the Multiple Events list screen, grouped under "MN Alarm".
• Latches the control panel in alarm. The control panel will not return to normal operation until the alarm condition is corrected and
the control panel is reset. Resets require two presses of the reset button if both MN and Fire events are present in the system. The
first press will reset the MN events, the second will reset the rest.
• Initiates any Control-By-Event (CBE) actions. If the node goes off-line, active logic equations with ZF20 in them will stay active
until MN reset.
• Sends an MN alarm message (ZF20) out to the network.

Network Activation
When an MN alarm is sent out to the network from the initiating node, each node on Noti•Fire•Net will check its MN map to determine
if it should react to the MN alarm. If a node has been programmed with the initiating node in its MN map, it will accept the MN alarm
from Noti•Fire•Net and react according to its programming.
• Logic equations with Special Function Zone ZF20 (MN alarm zone) in them will be evaluated.
• Fire alarms are suppressed if MN has the highest priority (Refer to "Output Event Suppression" on page 40).
• If the system is "ALL SYSTEMS NORMAL", NETWORK MN ACTIVE will display.
NFS2-640, NFS-320/SYS MN Activation

Local Activation
When an MN alarm activates locally, it:
• Produces a steady audible tone if the piezo is enabled.
• Illuminates the ACS LED dedicated to MN alarms (required for the NFS2-640 and NFS-320/SYS). No LED on the panel lights for
an MN alarm.
• Does not activate the alarm relays.
• Displays ALARM:ECS/MN MON in the upper left corner of the display, as well as other information specific to the alarm.
Displays MN ALM on LCD2-80/LCD-80 in terminal mode.
• Activates Special Function Zone ZF20 (MN alarm zone).
• Suppresses fire alarms if MN has the highest priority (refer to "Output Event Suppression" on page 40).
• Does not activate "General Alarm" or "Alarm Pending" type codes.
• Is block acknowledged in scrolling mode, acknowledged one-by-one in non-scrolling mode.
