Operation of the Control Panel Mass Notification Supervisory Event
2.9.2 How to Respond to an MN Alarm
If the control panel indicates a MN alarm, the operator can do the following:
1. To silence the panel sounder:
Press the ACKNOWLEDGE soft key. The local sounder will silence and the
OTHER LED will
change from flashing to steady. The control panel will send an acknowledge message to the
panel display, history buffer, installed printers and annunciators. If more than one MN alarm is
present on the control panel, Acknowledge must be pressed for each alarm.
2. To silence any activated outputs that are programmed as silenceable:
Press the SIGNAL SILENCE soft key.
SIGNALS SILENCED LED light steady. The control panel
sends a Signal Silenced message to the History buffer, installed printers and annunciators.
NOTE:
If MN events have priority over fire events, any active silenceable devices that were activated
by the fire event will silence when the MN Alarm occurs.
If fire events have priority over MNS events, silenceable outputs will remain active when an
MN Alarm occurs until SIGNAL SILENCE is pressed or a system reset is initiated.
3. Check the MN Alarm message for its location and type. Press the MORE INFORMATION 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 1.8 on page 19 for
an example of the this screen and an explanation of its fields.)
4. Correct the condition causing the MN alarm.
5. When the alarm condition is corrected, press the SYSTEM RESET soft key to return the control
panel to normal operation (indicated by the “System Normal” message). The control panel
sends a “System Normal” message to the panel display, History buffer and installed printer. If
both fire and MN alarms are present on the control panel and MN events have priority over fire
events, the initial reset will clear the MN alarm from the control panel. If fire has priority over
MN events, a second reset must be initiated to clear the MN alarm from the panel.
The soft key PROGRAM/ALTER STATUS is also displayed on this screen. A password is required
to enter these menus, which are described in the NFS2-3030 Programming Manual.
2.9.3 Interpreting Type ID Codes
The Type ID code that displays in the fire alarm message is related to the type and function of the
point that initiates the fire alarm. For example, a monitor module with a
MN MON Type ID code
means that the monitor module connects to a mass notification device. If the Type ID code is unfa-
miliar, refer to Appendix A, “Software Type ID Codes”, on page 78. This appendix is an alphabeti-
cal list of Type ID codes with an explanation of each.
2.10 Mass Notification Supervisory Event
An MN Supervisory point event will occur when a monitor module programmed with an MN
supervisory type code activates.
2.10.1 How the Control Panel Indicates an MN Supervisory Point
Event
The panel will react differently depending on whether or not there are higher priority unacknowl-
edged events.
When no higher priority unacknowledged events are exist, the control panel:
• Produces a warbling audible tone (if the piezo is enabled)
• Activates the Supervisory relay (TB2) and any devices programmed as General Supervisory
and General Pending
