XLS80e Fire Alarm Control Panels
14 Master/Slave Network
This section describes how to configure the
panel for use with a Master/Slave network only.
It does
not
describe the XLSNET peer-to-peer
network - refer to the XLSNET
Appendix 3
for
information about this alternative network.
A panel cannot simultaneously be attached to
both types of network. However, if it is on the
XLSNET network, the Master/Slave network
can still be used for repeaters as described in
the XLSNET manual.
14.1 Introduction
The XLS80e Series control panels can work
either as stand-alone units or networked with
other control panels and repeaters. When
networked, each control panel supervises its
own detection system of up to eight loops of
sensors and modules. It then functions
independently of all other panels.
An RS485 communication system enables
events at any panel to be relayed to all other
panels and repeaters, causing appropriate
annunciations and/or actions at those panels
or repeaters.
14.1.1 Number of Stations on Network
The network consists of one Master panel, a
number of Slave panels and (optional) a
number of Repeaters.
The term ‘Station’ is used to refer to the Master
panel, a Slave panel and a Repeater. The
network has a maximum of 32 stations.
Restrictions on the number of Slave panels
and Repeaters are detailed below.
14.1.1.1
Panels
Each Network must include
one
(and only one)
Master panel. This panel has overall control
of the network. It receives all networked
messages from the Slave panels and its
configuration determines how these are acted
upon and redistributed.
The network may also include up to
seven
Slave panels. These panels have independent
control of their own local loops, and report any
local events to the Master panel.
The Master/Slave
network does not
provide the transmission
path integrity required
