Performing a System Reset

4.2 Performing a System Reset
If both fire and MN events are present in the system, two button presses are required to reset the system. The first button press resets the
highest priority events, the second press resets the lowest priority events. When the first button press resets the highest priority events,
the lower priority events will resound, if necessary.
For example, when MN has the highest priority in a system, resetting a panel after an MN event has concluded requires two button
presses if there are fire events in the system. The first button press clears the MN alarms and supervisories, the second will reset the other
system events.
The NCA-2, NFS2-3030 and LCD-160 display the following text at the reset softkey, to indicate the type of reset being performed.

ONYXWorks Workstation displays different buttons for the different reset types.
An MN system reset is sent out over Noti•Fire•Net and picked up by participating MN nodes and the MN event will automatically clear
from their local systems.
MN and Fire Events Present in System
MN is the highest priority: When both MN and fire events are present in the system, and MN events have the highest priority, press the
panel's reset button to:
• Reset MN alarms and supervisories only (ZF20 and ZF21 activations, refer to "Special Function Zones" on page 25), clearing them
from the display and counters.
• Display an MN system reset message on the panel display, as well as on an LCD-160 if one is present.
• Turn off the "Other" LED if no active "other" events are in the system (NFS2-3030, NCA-2 only).
• Output processing:
– Turn back ON suppressed outputs (silenceable fire outputs, strobes).
– Clear general zones mapped to the MN events being cleared.
– Run logic equations.
– Re-evaluate outputs.
• Add an MN system reset entry to printer and history to indicate the MN events were reset.
• Send reset message for MN alarms and supervisories out to Noti•Fire•Net.
All network nodes will go through a 10 second decouple time.
Pressing Reset a second time will reset remaining system events.
Fire is the highest priority: When fire is the highest priority, press the panel's reset button to:
• Reset all events except MN events.
Pressing Reset a second time will reset MN events, and send a reset message for MN alarms and supervisories out to Noti•Fire•Net.
MN Events Only Present in System
When MN events have the highest priority and no other types of events are present in the system, pressing the panel's Reset button once
will:
• Reset MN alarms and supervisories only (ZF20 and ZF21 activations), clearing them from the display and counters.
• Display an MN network reset on the panel display, as well as on an LCD-160 if one is present.
• Turn off the "Other" LED if no active "other" events are in the system (NFS2-3030, NCA-2 only).
• Output processing:
– Clear general zones mapped to the MN events being cleared.
– Run logic equations.
– Re-evaluate outputs.
• Add an MN system reset entry to printer and history to indicate the MN events were reset.
• Send reset message for MN alarms and supervisories out to Noti•Fire•Net.
