11 MNS/ECS Application
This chapter covers the configuration of a 4100ES system to operate as a mass notification system (MNS).
11.1 Application of 4100ES as a UL2572 Mass Notification System
11.1.1

General Information

A 4100ES system with Basic Voice option 4100-9620 (analog), 4100-9621 (digital), or 4100-1412 (ES Net digital) can be configured for
operation as a Mass Notification System (MNS). Configuration of the system is to be done per UL2572, taking into account any special
requirements resulting from a Risk Analysis.
11.1.2 Hierarchy of Operator Interfaces
The 4100ES main user interface serves as the primary local control unit for the in-building MNS, called the Autonomous Control Unit. It is
an "authorized personnel" operator interface, that can take control of the paging and messaging features of the 4100ES system.
The ACU serves as the primary control station in the MNS, and as such has the highest priority among all operator interfaces attached to
the 4100ES system, including network interfaces such as a TrueSite Workstation. The hierarchy of operation is specified by UL2572 as:
• Autonomous Control Unit (ACU)
• Local Control Unit (LOC)
• Central Command Station (CCS)
A Local Control Unit (LOC) is an in-building operator interface for authorized personnel to initiate messages and signaling in an emergency
situation. An example of an LOC is a 4100 Remote Annunciator, configured with remote microphone and LED/Switch modules for
activation of the paging and emergency message features of the 4100ES.
A Central Command Station (CCS) is a networked user interface, such as TrueSite Workstation. These units can activate signaling over
a local in-building or campus network. A CCS is provided with a microphone, which may be a remote microphone, such as 4003-9803
wired from a 4100ES fire alarm node in the system. Another possibility would be a 4100-1244 remote microphone in a transponder bay
installed into a console at the CCS location. Alternately, a 4100ES may be rack-mounted as part of the command console, and the master
microphone would be available for this function.
The hierarchy of the operator interfaces is programmed using Custom Control. For example, the ACU could have a switch programmed to
be a priority 3, an LOC switch could be programmed as priority 4 and a CCS could have a switch programmed as priority 5. Refer to the ES
Panel Programmer's Manual (574-849) for detailed information about programming switch priority and writing custom control.
If transfer of control is required, LED/Switch points must be programmed to activate and to indicate the transfer of control to each desired
location. These switches would be programmed at different priorities and the LEDs would indicate the status of control.
Refer to document 900-249, 4100 Upgrade Audio Enhancement Guide for details on how to configure an audio system with multiple
command centers.
When any unit is in control, an LED must indicate the active control at each location. If a higher priority service takes control from a
lesser priority service, that should be indicated by extinguishing the LED or indicator for the lesser priority service and lighting the LED or
indicator for the greater priority service.
For example, if the LOC takes control, the CCS must be locked out from taking control and an indicator at the CCS must show that the
LOC is in control. If the ACU then takes control from the LOC, the indication must change at both the LOC and CCS that the ACU now has
control. In this case, both the LOC and CCS must be locked from taking control.
11.1.3 Priority of Signals
A Mass Notification System is often a combination of fire alarm and other signals. As such, it may receive signals that affect life safety that
are other than fire alarm signals. Any signal that indicates a danger to Life Safety, including fire alarm, is the highest priority. The highest
priority could also include intruder alert, tornado warning, or other signals as determined by the Risk Analysis.
If multiple signals are received simultaneously, the priority of signals is:
1. Signals associated with life safety
2. Signals associated with property safety
3. Supervisory signals and trouble signals associated with life and/or property safety
4. All other signals
In the 4100ES system, signal priority can be selected by assignment of point type and further by custom control. Refer to the ES Panel
Programmer's Manual (574-849) for detailed information about programming input point priority and writing custom control.
