Intrinsic Alarming: BACnet alarming that incorporates alarm destinations (via
Notification Classes) within a single alarm message.
M
multicast: Destination IP address that represents one or more interfaces. IP datagrams
sent to a multicast address will be sent to all hosts participating in this multicast group.
N
notification class: Notification Class supports enable/disable based on the day of week
and time of day and the alarm priority for all points associated with it.
P
Plain Old Telephone Service (POTS): Acronym for the standard telephone service that
is used in most homes. Communication speed is generally restricted to 52K bps.
point condition: State of a point such as normal, alarm, alarm-by-command, failed,
operator disabled, or proofing.
R
Read Only Memory (ROM): Non-volatile, permanent, but field-programmable memory
that stores the operating system of the field panel. ROM stays intact even in the event
of a power surge, a power loss, or failure of the battery backup.
Remote Automation Level Network (ALN): Automation Level Network (ALN) hosted by
a remote field panel. The ALN is only seen at the remote site and at a centrally located
Insight workstation.
remote field panel: Field panel not directly connected to the Insight ALN. Remote field
panels connect over the telephone lines using a dial-up modem, or over an Ethernet
network using an AEM/AEM100/AEM200.
S
service box: Component that receives the line power and converts it to 24 Vac for the
field panel.
T
telnet: Program that runs on top of TCP/IP, it is the Internet standard protocol for
remote login.
text-based terminal: Operator terminal that displays and accepts text only.
To-Fault: A BACnet event indicating that the BACnet object (point) has transitioned to
the Fault state from some other state for the recipient or device. A BACnet object
mayor may not require acknowledgement of this event by a user.
To-Normal: A BACnet event indicating that the BACnet object (point) has transitioned
to the Normal state from some other state for the recipient or device. A BACnet object
mayor may not require acknowledgement of this event by a user.
To-OffNormal: A BACnet event indicating that the BACnet object (point) has
transitioned to the OffNormal state from some other state for the recipient or device.
OffNormal states in BACnet are: OffNormal, high-limit, low-limit, and life-safety-alarm.
A BACnet object may or may not require acknowledgement of this event by a user.
tombstone: Remnant or memento of a deleted record that is retained for a finite
amount of time in a node’s replication database. Tombstones are used to keep track of
locally deleted records that must be deleted from replication partners during future
global data replication sessions.
totalized value: Sum of information (in hours or minutes) about logical points such as
run time, total volume, and degree days.
