The quoted performance is 9 Mbps over 2,000m or 3 Mbps over 5,000m
(0.5mm
2
cable). However the speed achieved will 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.
See Figure 11-29 for wiring, and refer to the PIB User Manual (LT0519)
for configuring the Ethernet Extenders
as “CO” (Central Office) or “CPE”
(Customer Premises Equipment).

The PIB (FP0986) is required to be earthed and the recommended
earthing method is via 2 metal standoffs (J17 and J19) in the positions
shown in Figure 11-30. The other standoffs may be plastic or metal. If
J17 and J19 are not earthed this way, then earth leads (included with the
PIB) must be fitted to the adjacent earth tabs J23 and J25, with the leads
electrically connected to the gearplate/cabinet earth.
