11.1.4 Overriding Fire Alarm Signals
An MNS/ECS system must have the capability to override any other notification signals. When the 4100ES is used as a combination fire
alarm/MNS, the system programming determines which signal has priority. Just as an Evacuation Message has higher priority than an Alert
Message, system programming gives priority to MNS functions over other alarm functions.
In the event that a fire alarm signal is overridden by the MNS signal, and the MNS signal is then "silenced", the building occupants need
to be assured that the evacuation system is still functioning. The standard evacuation signal is feature that is programmable in this 4100
panel and when used, it must set for no less than 3 minutes.
During the period the mass notification system has seized control of audible and/or visible notification appliances of a fire alarm, but
before the mass notification relinquishes control, an audible and visible signal shall be actuated by the notification appliances at least once
every thirty seconds, unless there is an active signal present, to be recognized by the usual building occupants.
With a 4100ES system, use Custom Control equations. A single flash and a short beep of audible and visible appliances meets this
requirement. Alternately, an appropriate prerecorded message may be played. For example, a message instructing occupants to "shelter
in place" may be played after a live microphone message. Risk Analysis by the AHJ should guide the appropriate pre-recorded messages.
Switches for activation of special messages should be marked so as to be identifiable during an emergency by trained personnel.
Custom Control equations for the "chirp/flash" of audible and visible appliances are suggested below.
The Automatic Alert Tone is programmable feature in the 4100 panel. You can create a message or use a pre-recorded message. You must
set it for 1 to 3 seconds. The 4100 panel can initiate a recorded message. If a previously initiated recorded message is interrupted by a
live voice instructions, the previously initiated recorded messages can be used in the selected notification zones when you release the
microphone. This feature also has the option to not resume play automatically.

11.1.7 Public Accessible Panic Switches
Some applications call for panic switches that are accessible to the public. Panic switches are input devices used to signal a non-fire
emergency, and could be used to trigger events and/or announcements in the building. If these switches are installed in public areas of
a building they would typically not automatically trigger a Mass Notification event. Instead, they would trigger the Command Center to
investigate the signal and make the appropriate announcement.
