NFS2-3030 Programming Manual — P/N 52545:K1 03/20/2012 131
Appendix E: CBE: Zones and Equations
CBE (Control-By-Event) is a software function that provides a means to program a variety of
output responses based on various initiating events. The control panel operates CBE through lists of
zones. A zone becomes listed when it is added to a point’s zone map through point programming.
• Each input point (detector, monitor module) can list up to ten zones. Allowable zone types
are general zone, releasing zone,
and special zone.
• Each output point (control module) can list up to ten zones. Allowable zone types are
general zone,
logic zone, releasing zone, special zone, and trouble zone.
• Output points can list zone Z000 (general alarm). Non-Alarm or Supervisory points do not
activate zone Z000 (general alarm).
Networked C
BE, or CCBE (Cooperative Control-By-Event), provides CBE initiating-event/output-
respon
se relationships over the network through general, logic, and/or trouble zones. One of these
zones, programmed into the zone maps of points on this panel and points on other nodes, will create
network cause-and-effect relationships based on the type and content of the zone.
E.1 Zones
There are four types of zones that may be listed to a point for CBE purposes.
Zone Type Description/Function
General Zone A general zone is used to link input and output devices. When an input device
activates, any general zone in its
zone map will be active, and any output device that has an active general zone in its map will be active. General
zones can be used as arguments in logic equations.
Zone Z000 is a general alarm zone: those points listing Z
000 in their zone map p
articipate in a general alarm.
The panel will support up to 1000 general zones, designated as Z0 through
Z999. General zones can be used in
CCBE applications when a node number is entered before the zone number.
Logic Zone A logic zone consists of a logic equation. Whenever
the logic e
quation becomes true, all output points mapped to
the logic zone will activate.
The panel will support up to 1000 logic zones, designated as ZL1 through
ZL1000. Logic zones can be used in
CCBE applications when a node number is entered before the zone number.
Trouble Zone A trouble zone consists of a trouble equation. Whenever the trou
ble eq
uation becomes true, all output points
mapped to the trouble zone will activate.
The panel will support up to one hundred trouble zones, designated as Z
T001 through ZT100. Trouble zones can
be used in CCBE applications when a node number is entered before the zone number.
NOTE: Trouble zones can be used only in CCBE applications be
tween NFS2-3030, NFS-3030 and NFS-640
FACPs. Trouble zones will not activate with other combinations.
Releasing Zone A releasing zone is used to contr
ol a r
eleasing operation.
The panel will support up to ten releasing zones, designated as ZR00 through ZR09.
