Information Distribution Via Network - Honeywell XLS80e Manual

XLS80e Fire Alarm Control Panels
On the Master/Slave network, remote network
zones cannot be selected from a menu. When
configuring the Control Matrix, the choice
'Zones on this panel only/Zones on all network
panels' is given. If the latter option is chosen,
the appropriate network zone number must be
entered via the panel pushbuttons. To display
the local zone number corresponding to a
network zone number that is owned by the
current panel, press the
access level 2) - second operation re-displays
the network zone number.
If zone indicator lamps are fitted, they indicate
the status of the network zone numbers up to
a maximum of 256; higher numbers cannot
be indicated.
Network Zones - XLSNET (refer to
Appendix 3 for details of this network)
The maximum number of zones is 8160 (255
x 32 panels max.) numbered in the range 1 to
8192. Remote network zones can be selected
directly from menus. Other information is as
described for network zones on the Master/
Slave network.
14.1.3 Information Distribution via
Network
The protocol for information transfer via the
Network is mostly event-driven. When any
significant change-of-state occurs in a panel,
that panel sends a message to all other panels
and repeaters, with a full description of the
event. If the event involves a sensor or module,
full information about that device, including its
zone, device type, and text name (if any), are
included in the message. Accordingly, it is not
necessary for panels to store configuration
details for every device on every other panel,
since that information is made available to
them if the need arises.
In addition to event-driven communications,
time/status checks are broadcast around the
Network at regular intervals to assure the
correct functioning of all stations and to verify
clock synchronisation.
Note: It is not possible for two stations on the
Network to display different times on
their system clocks.
