The PIB is connected to the Moxa Fibre/Ethernet switch as shown in Figure 30.
Figure 30 – PIB and Moxa Switch Wiring
Two standard versions of the Moxa fibre switch are available from Johnson Controls:
If shielded CAT3/5/6 copper Ethernet cable (STP) is being used to connect from one Moxa switch to the next
(<100m) refer to the PIB User Manual (LT0519) for installation and wiring details.
A Westermo Ethernet Extender module (SU0328) may be used to provide a bidirectional extension of Ethernet
signals over a single cable pair. It is designed for use with telephone cable, but will generally work with other cable
types, albeit over a shorter distance for the same speed.
The quoted performance is 9 Mbps over 2,000m or 3 Mbps over 5,000m (0.5mm
2
cable). However the speed
achieved may vary depending on the cable. If you propose to use an Ethernet Extender over existing cabling that is
not telephone cable, it would be prudent to do some tests before assuming that the existing cable will be
satisfactory.
Note: 3 Mbps is adequate for most fire networks.
