Mass Notification
A location of mass notification system control (ACU) consists of the following:
1. A list of Speaker Groups to be controlled/monitored.
2. A set of Voice Applications to be performed on the Speaker Groups (for example,
ALL CALL, SELECT EVAC, DISPLAY ALERT, etc.).
3. An LVM microphone.
4. An optional list of telephone groups and an FMT master phone.
5. Request/Grant/Deny access.
A mass notification system may have one or more different locations of control over
the same installed equipment. In a single-node system, a command station with a
PMI located in a CAB enclosure is considered an Autonomous Control Unit (ACU). A
single-node combined system (Fire Alarm + MNS) can only have one ACU.
In a multi-node system with MNS enabled, a Global Voice configuration is required.
An ACU is then synonymous with Display and Control Centre (i.e. a Global command
station including a Global PMI with control). Zeus allows up to five ACUs (i.e. Display
and Control Centres configured as Global command stations including a Global PMI
with control) on a Global Voice network.
In order to maintain a single point of control over the entire system, local nodes must be
configured as display only, and their local command station can only be used in the advent of
a network degrade situation (i.e. when there is no longer a Display and Control Centre that is
able to control the local node).
The MNS application uses the FireFinder-XLS Voice system to accomplish its func-
tionality via switches (e.g. SCM). Individual zone circuits (speaker, strobe) are bundled
into geographic groups during system configuration. These groups are either auto-
matically controlled by pre-programmed system logic, or manually controlled by the
switches located on Autonomous Control Units (ACUs). They can be dedicated to Fire
annunciation only, to MNS annunciation only, or they can be used to annunciate
messages from MNS and from Fire audio channels alike, based on audio channel
priorities. Paging, manual control, or monitoring of the speaker groups can be
performed from any location where an LVM/LPB microphone, SCM switch control
module, or PMI is installed.
