INSTALLATION
CABLING
The repeater panels are designed to be wired in a fault tolerant (fail safe) loop confi guration, from Comms
A +/- to Comms B +/- on the next repeater panel and so on until returning to Comms B +/- on the main
panel again (see diagram). This enables repeater panels to still work if there is a break in the cables. Up
to 1Km of cable can be used between each repeater. 120R terminating resistors can be used to reduce
interference between each leg of the loop.
Any suitable screened cable can be used or fi re resistant cable, ‘NoBurn’, FP200 etc.
If replacing an older system where the existing cabling cannot be confi gured in a loop as shown, it is
possible to re-programme the panel back to legacy, radial circuit comms monitoring. This then allows any
topology of comms cabling to be utilised.
To change the repeater comms monitoring type from Fault Tolerant to Radial/Legacy, see page 7.
