Description
1.
LAN segment 1 extends from the Challenger panel to one side of the TS0893 LAN
Isolation Interface. Termination is ON at the panel and the panel’s side of the TS0893.
Maximum cabling distance for segment 1 is 1500 metres.
2.
LAN segment 2 extends from the TS0893 in building A to the TS0893 in building B.
Termination is ON at both TS0893 modules. Maximum cabling distance for segment 2 is
1500 metres.
3.
Earth point on Challenger panel connected to building earth via plug pack earth wire
(green).
4.
Earth point on remote device connected to building earth via plug pack earth wire (green),
or earth wire from local power supply.
5.
Plastic-body LAN device. Join data cable shields where cable extends past a device that
doesn’t have a LAN earth connection.
Using LAN devices to facilitate cabling
Various LAN devices may be used to provide electrical isolation and to reduce
cabling costs. LAN isolation devices can also be used to extend the distance of
LAN cabling beyond what can be achieved by a single cable run of 1.5 km. LAN
devices include the following:
• TS0844 Power Distribution Board.
The TS0844 module can be used in
either data or power mode, as set by a pair of onboard links. The TS0844
module expands the number of physical connections that can be made to the
panel’s power or data output terminals.
• In data mode, each TS0844 module provides five sets of LAN out
connections and five sets of + and
– auxiliary power output terminals.
• In power mode, each TS0844 module provides 10 sets of + and – auxiliary
power output terminals.
A TS0844 module is shown in Figure 2 on page 7.
• TS0893 LAN Isolation Interface.
Provides an optical isolation barrier
between components on a Challenger (or Intelligent Access Controller) LAN.
The TS0893 can be also used as a LAN repeater; with up to three stages
cascaded together to increase the maximum LAN cabling run from 1.5 km to
6 km. TS0893 modules are shown in Figure 3 on page 7.
• TS0896 RS-485 to Fibre Optic Interface.
A pair of TS0896 modules, with
suitable optical fibre cable, may be used to extend the LAN to remote
buildings or locations within a building (for example where unused optical
fibre cable already exists).
• TS0098 Challenger IP LAN Adaptor:
Multiple IP LAN Adaptor modules
enable Challenger LAN data to be carried over an IP network and to be
converted back to RS-485 communications for connection to LAN devices.

LAN devices.
